PATROL LOGS
USS SUNFISH SS281
1ST PATROL, COMMENTS ON
:The first patrol went from 23 Nov, 1942 to 14 Jan, 1943. Out of a period of fifty-two days, twenty-eight were spent in the patrol area. The assigned mission was to conduct an offensive patrol against enemy forces, including merchant shipping, and to plant an offensive minefield after through reconnaissance. The Commanding Officer was handicapped by his impression that he had to remain on the defensive until after laying the mine plants.
This patrol was characterized by lack of aggressiveness in attacking good targets. The contact at 1035 on 10 December should have been attacked, not evaded at deep depth. Additional targets were passed by and evaded on December 19, 20, 23, and Jan 2, 1943. The watchword of any successful Submarine Commanding Officer must always be "aggressive attack." Enemy destroyers make excellent targets and they have no perogative of freedom from attack.
The SUNFISH left for patrol with 16 torpedoes and 24 Mark 12 mines. Both before and after laying the mines, a number of excellent opportunities for torpedo attacks were lost. To any one submarine, opportunities for attack come relatively seldom.
Enemy targets at hand must be attacked and sunk. (J.H. Brown, Jr.)
Nov 25-27, 1942.
Enroute Pearl Harbor to Midway. Heavy seas and gales reduced speed 3 to 5 knots. Made dive to 250 feet for training and test. Flooded antenna trunk. Superstructure immediately abaft forward capstan stove in by heavy seas.
Nov 28, 1942.
1147 Arrived at Submarine Base, Midway. Bow buoyancy vent operating levers and bell cranks are supported in this portion of stove in superstructure. When the deck bracing carried away, bow buoyancy operating levers failed to close the vents completely, resulting in out taking heavy seas over the bow. Number 2 periscope packing gland and SJ radar packing gland leaked badly at 250 feet and the radio antenna trunk was flooded. The SD radar had been acting peculiarly, so remained at Midway overnight and part of the next day in order to effect repairs and adjustments.
Dec 1-4, 1942.
Incl Held daily surprise dives, fore control drills, school, fired 15 rds of common from the 3" gun, simulating battle surface, and fired triple mount 20mm. Serviced torpedoes. Weather for these days was excellent.
Dec 7, 1942.
Sea rough, wind high, from the west.
1400 Nothing sighted so resumed base course to close HACHIJO SHIMA. Zigzagging.
1625 Sighted same patrol vessel as previously during the day, bearing 277 T, distance 6 miles.
1626 Dived. O.O.D.'S DESCRIPTION: Vessel was 100-150' in length, painted gray, had 50' mast and box-like superstructure amidships; seemed to ride high in the water. Nothing could be seen through the periscope, so at
1658 Surfaced on southerly course and immediately sighted same patrol vessel, distance 4 miles, heading in our direction.
1659 Dived to open out. Because of the mine-laying mission of this vessel I consider it essential that we are not detected enroute to area, or in the area until the mine plant has been accomplished. The decision has been made, therefore, to avoid contact with minor vessels, the sinking of which would not be worthy of jeopardizing the primary mission.
Dec 8, 1942.
Running on surface, sea rough, wind high.
1036 Sighted HACHIJO SHIMA, bearing 265 T, est distance 40 miles.
1213 Contact sighted through periscope and identified as 100 foot sampan. Description: Brown in color, clipper bow, mast abaft deck house and another mast astern, possibly for radio antenna. From our position 800 yards away, this vessel appeared to have lumber piled on the after deck, though where such a vessel could be taking lumber on a course east of HACHIJO SHIMA is inconceivable. Worked around contact and decided to remain submerged the remainder of the day in order to pass HACHIJO SHIMA during darkness.
Dec 9, 1942.
2235 On course 000 T, closing DAIO SAKI. SJ radar contact bearing 130 T range 13,000 yards. Immediately put contact astern and commenced tracking on course 310 T. (Lat 33-58 N/Long 137-14 E)
2241 Control party tracked target out to 15,000 yards. At this point, I had to make the decision whether this target was valuable enough to shoot at, thereby disclosing our presence in the area prior even to reconnoitering for the mine plant. The target evidently had at least 90 deg angle on the port bow, which would have meant high speed running to get into firing position. If we sank the target our presence would definitely be discovered and the mine plant might become impracticable due to intensified anti-submarine activity, since it was estimated that we would close NAGOYA considerably during the approach. Judging from the size of the "pip" on the SJ radar at 15,000 yards, this was a worthwhile target. It was decided to attack. Went to battle stations. continued tracking on courses between 300 and 071 T. Target was zigzagging radically.
2311 Went ahead 80-90% on 4 main engines.
2321 Believe target's base course is 350-000 T, which would indicate his destination is NAGOYA. Target's speed by plot and TDC is 14.0 knots.
2348 Went to full power on four main engines. Target sighted. Has lines of a destroyer when seen from 12,000 yards, but radar indicated a much larger ship. Appears to be a heavy cruiser or aircraft tender of CHIYODA or MIZUHO class. At no time during run for position ahead did we get closer than 9,850 yards. Decided to attack if we could get into firing position before target changed course radically to westward to enter NAGOYA.
Dec 10, 1942.
0035 Range 8,000 yards; dived for attack, using SJ radar.
0108 Plot and TDC discovered target had changed course to his right 120 T and was headed away.
0110 Surfaced and commenced rapid pursuit in target's direction but the range opened rapidly.
0140 Changed to 160 T and slowed to two engine speed. The battery and air tanks had not been completely charged when contact was made, so decided to give up chase, since target was lost at 15,000 yards and probably suspected our presence.
0940 Heard pinging, getting louder, bearing 200 T.
1035 Sighted smoke, masts in line, and fighting top of pinging ship. Surfaced heat waves blanked out vessel from bridge to water line, so identification could not be definite. Apparently a DD, however and close, because screws were heard plainly.
1043 Rigged for silent running and went to deep submergence - 425 feet. At 400 feet the pinging stopped. Upon reaching 350 feet the pinging was again heard.
1235 Finally succeeded in putting DD astern, pinging getting weaker.
1749 Surfaced. Sighted lights of sampans. Maneuvered to avoid.
0528 Standing by to make morning dive. SJ radar contact bearing 135 T, distance 13,000 yards. Two ships were dimly sighted, in the morning twilight, angle on the bow 120 port. Too far to close submerged and now too light for a surface attack.
0530 Dived. Heard faint pinging that was soon lost.
0819 Conducted periscope patrol south of ENSHU NADA during the day.
Dec 12, 1942.
0503 Dived on 100 fathom curve to reconnoiter western approach to IRAKO SUIDO.
0616 Sighted small coastal freighter (2500 tons.) Bearing 31 T, distance 5,000 yards, course 265 T.
0636 Sighted small coastal freighter (2500 tons.) Bearing 32 T, distance 3,500 yards, course 265 T.
0925 Sighted tops of man of war, bearing 000 T, distance 6,000 yards. Course 090 T. This contact similar in size to light cruiser, had two tall vertical stacks, a tripod mast forward, what appeared to be a director control station or large lookout station atop forward mast, and had a stick mast aft, with no top or crow's nest. Reconnoitering for mine plant with such targets available requires will power.
1110 Periscope depth control lost.
1115 Periscope depth regained so I looked again at the above-mentioned contact and saw the tops of the man of war, angle on the bow zero, estimated range 5,000 yards, speed 15 knots. During approach (by target) depth control was lost and only three quick observations were made prior to final setup. These were enough to revise speed estimate to 18 knots but not sufficient to identify target as to type. Only two tubes aft were loaded with torpedoes so at,
1122 Fired first torpedo, 10 L on TDC.
1122-40 Fired second torpedo, gyro 30 L on TDC. Both missed. Target is similar to a CA of the KINUGASA class.
1224 Came right for possible bow shot as target was coming left rapidly to head for us. I believe target is a DD.
1225 While coming around for a bow shot, lost depth control and periscope went under. Since we were going down anyway--
1226 Went deep and rigged for depth charge and silent running.
1127-1531 Heard screws of three ships (one heavy and slow). Contact fired upon made several approaches. His screws were so heavy that they vibrated the conning tower. No pinging was heard and no depth charges were dropped. The torpedoes fired went out at 63 deg right. Gyro power setting was not switched on in the control room and the after torpedo room failed to match up by hand. This was a very discouraging experience.
1531 Screws faded out.
1542 Periscope depth. Nothing sighted.
Dec 13, 1942.
Incl Patrolled during the day at periscope depth on VAN DIEMEN-TOKYO route.
Dec 14, 1942.
Decided to lay one field this date.
0529 Submerged to close KAMI SHIMA.
1630 Battle stations submerged.
1640 Commenced mine laying in depth of water 12 to 20 fathoms on various courses.
1649 Sighted large patrol vessel bearing 135 T, distance 2,000 yards, on northerly course. Passed 500 yards astern. Continued to lay mines as felt sound conditions were poor and there was much to do.
1731 Completed first mine plant. Headed south to clear the area.
1952 Surfaced in bright moonlight and cleared the area. (1.170 battery gravity)
Dec 15, 1942.
0253 Fire in the main control cell. Stopped engines and lay to while investigating cause. Smoke so thick in maneuvering room couldn't locate cause immediately.
0258 Went ahead on port screw taking suction for engine through maneuvering room induction to clear the smoke. The cork insulation over the starboard main motor resistor was flaming and smoking. Fire impossible to extinguish unless cork could be cut away but cork was inaccessible because control cell was energized. Continued to clear the area.
0503 Fire was extinguished, smoke cleared, and temporary wiring repairs made to control cell. Still cannot use starboard screw because of burned out starting grid resistor.
0537 Dived at daybreak. Using port screw. Starboard screw still out of commission. This casualty delayed the second mine plant much to the disappointment of all hands. We have had the mine plant hanging over our heads and have had to remain on the defensive so far in order to remain undetected.
1756 Surfaced. Patrolled during the night in and out of bright moonlight.
Dec 16, 1942.
0033 Moonset. Stopped, lay to, and pulled battery disconnects to make repairs to control cell.
0313 Completed repairs and tests of starboard main motor circuit. Everything satisfactory.
0314 Headed north at 15 knots to arrive in position for second mine plant during the day, weather permitting.
Dec 17, 1942.
Closing coast of ATSUMI HANTO
0256 Commenced second mine plant.
0410 Completed second mine plant.
0411 Commenced retirement to southward at four engine speed to get clear of 120 fathom curve as soon as possible.
0431 Good "pip" on SJ radar ahead and closing rapidly from 5,950 yards. (Lat 34-24.7 N/Long 137-18 E)
0432 Dived and continued retirement to southward of minefield. Crew had been at battle stations for considerable time so decided to conduct patrol away from coast during the day to rest the crew.
Dec 18, 1942.
0650 8 miles southeast of DAIO SAKI sighted what appeared to be a large freighter smoking heavily bearing 201 T, distance 8,000 yards, on northwest course. Commenced approach. (Lat 34-10 N/Long 136-52 E)
0727.40 Fired first torpedo - gyro angle 349.
0727.53 Fired second torpedo - gyro angle 339.
0728.10 Fired third torpedo - gyro angle 324.
All torpedoes missed due to failure to set a reduced range into the TDC. This was a control error due to the sudden zig of the target towards us, just prior to firing. The range setup was 1,300 yards and should have been 700 yards. This caused larger gyro angles than anticipated and must have thrown all torpedoes astern of the target.
0730 One depth charge or bomb (not close). Started to swing for stern shot but freighter opened range rapidly. Went to 150 feet.
0733.20 Second bomb or depth charge as we passed 80 feet, closer than the first. At 10 seconds later, third explosion, closer than second.
1024 At periscope depth sighted low-wing monoplane with single float, distance 4 miles, circling approximate position of attack. Nothing seen of the freighter so presumed she had gone into IRAKO SUIDO.
1043 Heard and felt explosions at great distance. Wishful thinkers hoped the target had crossed our minefield, which was in close proximity to her track.
Dec 19, 1942.
0541 Submerged off vicinity of MIKI SAKI; position doubtful.
2144 Making standard speed to avoid surfacing in heavy seas. Sighted DD or torpedo boat of TIDORI class through periscope, distance 4,000 yards. Rigged for silent running and went to 150 feet to clear area.
Dec 20, 1942.
0132 Surfaced on easterly course to charge batteries.
0149 SJ radar contact bearing 345 T, range 7,150 yards. Believed to be DD sighted earlier. Attempted to evade on the surface though in bright moonlight so put the DD astern. DD came left after us so at
0151 Dived. Battery too low to run at periscope depth so ran at 140 feet for the remainder of the night and conducted infrequent periscope observations during the day to conserve the battery.
1817 Surfaced.
1927 Resumed battery charge. Nothing further sighted this night.
Dec 21, 1942.
1747 Sighted running light of plane.
1818 Surfaced.
Dec 22, 1942.
0532 Submerged on northerly course close to coast south of FUKUDA where the 100 fathom curve cuts close to the beach.
1500 Sighted smoke and masts of several ships, bearing 285 T. Commenced approach. Targets tentatively identified as three medium sized freighters. The gap between ships was filled by a DD. During one observation sighted biplane circling in our vicinity so went to 90 feet and continued approach. When final bearing was close, I raised the periscope only to find that the minimum range to any target was 3,000 yards. No torpedoes were fired. The escort had very effectively thrown me off track. Since a new or previously unknown shipping lane had been discovered by us, decided that there would be more good hunting in this vicinity. (Lat 34-16 N/Long 138-08 E)
Dec 28, 1942.
1519 O.O.D. sighted plane bearing 090 T, distance 5 miles on southerly course, not picked up on SD radar. Tried to submerge but couldn't get down. All vents showed "open" on the indicator board. By going ahead emergency, went to 100 feet, only to come back to 35 feet as soon as speed was reduced. This was a helpless feeling. Used maximum speed and flooded auxiliary tanks to stay under.
1738 Surfaced. After sunset examined bow buoyancy vent operating gear to determine if misaligned. Everything appears normal. The cause of this remains a mystery and it is hoped that this never happens again, especially under such circumstances.
January 13, 1943.
1216 Enroute to MIDWAY. O.O.D. sights what appears to be life ring from Jap ship. Maneuvered to pick up ring.
1456 While almost dead in the water, took two waves over the bow. The second wave carried Harrleson, H.F. SM 1/C, over the port side and rapidly astern. Immediately began maneuvering to pick up man lost overboard.
1500 Harrelson disappeared from sight and was not seen again.
1556 Picked up life ring.
1825 Held funeral service for Harrelson. Lat 32-29 N/Long 172-33 E
Jan 14, 1943.
1238 Arrived Submarine Base, midway, for refit.
2ND PATROL, COMMENTS ON:
The second patrol of the SUNFISH was carried out in an aggressive and successful manner. The attack on the ASAMA MARU class transport was well executed in spite of an unfavorable zig that unfortunately forced the SUNFISH to change bow to stern shots at the last moment. A number of fast targets were encountered in the patrol area. Contacts were aggressively developed and all attacks were well conducted. (J.H. Brown, Jr.)
Sunk
1 - Freighter (TAZAN MARU class) 5,478 tons
1 - Freighter (ARGUN MARU class) 6,662 tons
12,140 tons
Damaged
1 - Transport (ASAMA MARU class) 16,975 tons
From: Commanding Officer Submarine Squadron TEN.
Subj: USS SUNFISH SS281, 2nd patrol, comments on.
The second war patrol of the SUNFISH was aggressive and well conducted. The patrol extended over a period of 57 days of which, 33 days were spent in the patrol area or in close proximity. The employment of the direction finder in listening in on distress frequencies after a torpedo attack has been delivered in a NEW INNOVATION. This appears to have possibilities in tracking damaged vessels with the object of maneuvering into position for a further attack and subsequent sinking. The C.O., officers, and crew of the SUNFISH are congratulated on their aggressive, well-conducted patrol.
Feb 4, 1943.
1003 Departed Submarine Base, Midway, enroute area.
Feb 5-11, 1943.
Conducted daily surprise dives, drills, and other activities for new personnel. Weather excellent.
Feb 14, 1943.
1241 60 miles from CHICHI SHIMA air base, dived to avoid detection by aircraft.
Feb 16, 1943.
0110 Heavy seas pounded superstructure, came over bridge and down conning tower hatch. Pit log jumping from 10-14 knots. Average 12 knots.
1737 Sighted mast and stack of ship through #1 periscope, bearing 250 T, estimated distance 15 miles. Range closing rapidly.
1740 Dived to escape detection and ran at high speed toward contact's estimated track, alternating high speed running at 75 feet with low speed periscope observations at 48 feet. Ship was not identified and was not seen again. Ass't O.O.D. thought that it was a large man of war.
1845 Surfaced, nothing in sight.
Feb 18, 1943.
0300 Entered patrol area.
Feb 22, 1943.
1106 Sighted smoke on horizon bearing 276 T, drawing to northward. Commenced approach at 6 knots.
1227 Ship identified as small freighter which passed very close to land. Detection would have been certain before favorable firing position could have been gained. Abandoned approach.
Mar 4, 1943.
0626 Sighted tanker through surface fog, bearing 110 T, 8,000 yards. Commenced approach. Using high speed to close but range opened and at 0820 tanker disappeared in fog. Prepared for surface chase.
0825 Prepatory to surfacing, sighted masts and stack of large ship bearing 250 T, hull down, seen only occasionally through mist or fog. Commenced high speed approach.
1100 Identified ship as BAIKAL MARU, painted white and ascertained that she was listed as a hospital ship. Abandoned approach on BAIKAL MARU.
Mar 7, 1943.
2020 SJ radar contact, bearing 290 T, 6,000 yards. Nothing sighted, poor horizon. Commenced approach. Radar "pip" indicates small ship.
2147 Fired 4 torpedoes at heavily loaded freighter, 90 S track, 5 deg spread, 8 seconds apart, depth 10 feet, greatest gyro angle 5 L, range 1,000-900 yards. First went ahead, two and three ran under ship. No explosions heard or felt on bridge but noted large spray of water followed by dense smoke from position of after hold. Thought bow shots failed to explode or ran deep. As freighter swung left to ram, range 800 yards, SUNFISH swung left for stern shots and as freighter presented 90 S track for the second time, fired 3 stern shots, 3 deg spread, range 900 yards, depth 5 feet, greatest gyro angle 5 R, 8 sec apart. First torpedo went ahead and enemy swung left to avoid. Second ran under target that was now completely obscured by smoke; third torpedo track went into the densest part of smoke. Still had no heard or felt explosions on the bridge and could not see if freighter was sinking due to smoke.
2150 Saw orange flame shoot from position of ventilator abaft stack and felt explosion on bridge, probably from boiler explosion.
2153 Freighter commenced firing gun. Over in range but close in deflection. Scream of shells passing overhead heard in conning tower. Dived to get clear of gunfire and to reload.
2205 Screws stopped fairly close aboard, feebly started then stopped and were not heard again. Shortly, sound heard loud crackling noises never heard before on SUNFISH sound gear and on last bearing of screws. Wanted to surface immediately but had unwisely commenced reload.
2240 Surfaced. Detected distinct smell of smoke. Searched area for one hour. Consider this ship sunk.
Mar 9, 1943.
1613 Position 044 T, distance 58 miles from TUNGYUNG TAO LT. Sighted mast of ship bearing 034 T, barely visible on horizon. Headed for contact and commenced approach.
1615 Raised periscope for another look and saw large passenger ship, stack, and superstructure up over horizon. Estimated speed at 20 knots - angle on the bow zero.
1618 Enemy zigged 20-30 degs right, showing two fat stacks, tremendous beam and superstructure, two single masts with outstanding cross-trees placed well above top of stacks. painted gray. At 2,500 yards angle on bow 10 P.
1639 Commenced firing 4 torpedoes, 81-87 P track, 4 deg spread, gyros 9-3 R, depth 20 feet, interval 10-8-8 seconds.
Estimated torpedo run 850-950 yards.
1639.40 First of three explosions which closely matched firing interval and torpedo runs for hits by first three torpedoes. Shortly after all torpedoes were fired, raised periscope and saw large column of water rising under forward funnel. Immediately lowered periscope and ordered 145 feet. (Charted water 162 feet) About this time, as SUNFISH passed 70 feet, DD's screws were plainly heard passing over conning tower.
1644-1709 8 depth charges, all very close. SUNFISH at 145 feet, running silent. Knocked paint and cork off hull, loosened bolts, put out lights temporarily, broke lights, emptied drawers in yeoman's office, etc.
1710 Destroyer's screws faded out on steady 270 T bearing.
1936 Surfaced with light of one vessel in sight on horizon. Cleared eastward to inspect for topside damage, effect repairs, and to close 200 volt battery ground. After surfacing manned distress frequency and obtained strong signal on 270 T where light was previously seen. Transmission stopped suddenly and was not heard again during the night though radio KELUNG was heard to ask whether distress signal of ship had been cleared.
Mar 13, 1943.
1516 Sighted smoke bearing 254 T. Commenced approach on smoke.
1516-1707 Tracked target, minimum range 8,000 yards, course 020 T, speed 12 knots.
1753 Surfaced and ran at 3 engine speed, charging batteries, trailing freighter.
2132 Reached position and submerged for periscope attack. Moon high, visibility good in target's direction.
2218 Fired 3 bow tubes, range 1,300 yards, 105-110 starboard track, gyros 0-5L, 5 deg spread, interval 8 secs, depth 10 feet.
2219.05 First of two explosions which corresponded in time with hits by 2nd and 3rd torpedo. Observed large column of water under after hold which momentarily obscured middle of freighter. Target's screws still turning, heading for TAKARA JIMA, smoking heavily.
2223 Violent explosion simultaneous with orange flame from ventilator abaft stack. Probably a boiler explosion.
2243 Underwater explosion on bearing of freighter followed by her sinking on an even keel.
2248 Surfaced. Patrolling southeast AMAMI O'SHIMA.
Mar 25, 1943.
1055 Sighted type 98 heavy bomber bearing 330 rel, distance one mile, crossing bow on course 180 T. Bomber came out of fog bank and apparently was as surprised as we were. Sighting seemed simultaneous; bomber banked for approach (Rising Sun plainly seen with naked eye) as SUNFISH dived. SUNFISH leveled off at 200 feet when first of stick of 3 bombs exploded. First was close, second and third barely audible. No damage.
Mar 29, 1943.
1024 Moored at S/M Base, Midway.
3RD WAR PATROL, COMMENTS ON:
The SUNFISH was at sea for 56 days on the third war patrol and spent 38 days in the assigned areas. While in enemy areas SUNFISH sighted 8 enemy aircraft and was depth bombed by one of them. Two submarine periscopes were sighted and disappeared before attack could be made. SUNFISH conducted successful night bombardment of FAIS without enemy opposition. It is regretted that the only worthwhile contact made by SUNFISH did not result in attack.
Apr 28, 1943.
0849 Departed Pearl with PC escort.
May 13, 1943.
1111 Dived on sight contact - type 95 observation plane. Remained submerged until dark.
May 15, 1943.
0032 Patrolled PALAU-MARIANAS-BONIN-EMPIRE route.
May 23, 1943.
Reconnoitered ANGAUR ISLAND, western side, from position 2 to 6 miles offshore. Took pictures while closing, but by 1500, rain squalls prevented pictures.
May 24, 1943.
0234 Sighted patrol vessel bearing 150 T, 4 miles which turned and headed towards SUNFISH. We were not challenged. Circled at 4 engine speed in search of possible shipping astern. There must be shipping where patrols are so much in evidence.
May 27, 1943.
1336 Close-in reconnaissance of FAIS. When close enough to island to see sun-bathers on the beach, opened out and gave gunnery personnel a look and instructions.
May 28, 1943.
0046 Closing FAIS at battle stations surface.
0128 FAIS now silhouetted in rising moon at radar range 7800 yards. First few shots were slightly left of the refinery buildings but were quickly spotted on in deflection and from then on all salvos, spotted up and down to cover range. Rooftops were illuminated by shells exploding as they pierced. After expending 26 rounds of 3 inch HC ammo, satisfied that the Japs would have some repair work and probably a case of the jitters, at least.
May 29, 1943.
Received COMSUBPAC information regarding A/S measures here. To date, SD radar has indicated presence of only one plane before plane was sighted. The result is that SUNFISH probably has lookouts second to none. They have had plenty of experience on this patrol. Departed area for TRUK.
Jun 2, 1943.
Patrolled HADDOCK's "thrill a minute" area and the area between HALL and NAMOUITO islands.
Jun 10, 1943.
0515 Sighted unidentified plane to eastward and shortly saw smoke and masts, range 20,000 yards.
0620 Range 10,000 yards, angle on the bow 90 S. Best position attainable was 6,000 yards, 150 S bow angle. Convoy course 180 T, speed 8 knots. trailed at 3 knots with plan to surface for end-around when range had opened to 20-25 miles to lessen interference by aircraft.
1107 Smoke still in sight; preparing to surface. Commenced high speed approach and during the next few minutes sighted two additional sets of masts to left of first. Broke off attack when at 1240 Identified vessels as two tuna-type patrols and one catcher trawler. They remained in sight and prevented surfacing as earlier planned.
1833 Surfaced at sunset and ran at best speed in pursuit of convoy.
Jun 11, 1943.
When contact not regained at 0030, the time estimated for contact, converged on original track and at daylight dived 15 miles ahead of estimated position. These tactics, with excellent visibility existing during darkness, should have covered a lane at least 30 miles wide along estimated track but contact was not regained. The only worthwhile contact on this patrol has slipped by.
Jun 19, 1943.
1230 Simultaneous with 40 deg left zig lookout sighted periscope on starboard quarter. Made ready stern tunes and put reported bearing stern. Periscope not seen again so did not fire. Sent contact report to COMSUBPAC.
Jun 24, 1943.
1059 Moored S/M Base Pearl Harbor.
4th PATROL, COMMENTS ON:
The fourth war patrol of the SUNFISH was conducted in an aggressive manner. Contacts were numerous and the SUNFISH took advantage of them by making five good attacks. Excellent teamwork of the SUNFISH organization was apparent. This patrol is considered successful for the purpose of Combat Insignia Award.
(C.A. LOCKWOOD, Jr.)
Sunk
1 Tanker (RIKKO MARU class) 9,182 tons
1 Freighter (KASIMA Maru class) 9,908 tons
1 Transport (class unk) 10,000 tons
29,090 tons
Damaged
1 Transport (KOKURYU MARU class) 7,369 tons
1 Freighter (TAIGEN MARU class) 5,660 tons

All attacks made by the SUNFISH were well planned and well executed in the face of strong anti-sub measures. It is believed that the AK hit in the 18 September attack sank. However, positive evidence is lacking. The Commander Sub Squadron TEN congratulates the Commanding Officer and personnel of the SUNFISH for a highly successful war patrol. (C.W. STYER)
Jul 28, 1943.
1501 Departed Pearl with PC escort.
Aug 13, 1943.
1659 Sighted 3 faint columns of smoke bearing 155 T; altered course to close, commenced tracking and started battery charge. After dark, closed to 20,000 yards and tracked by eye. Saw two large ships on line of bearing. Visibility excellent.
2137 Battery charge complete. Dived on track and headed towards targets which had been tracked on base course 345 T, speed 8 knots, with 20 deg zigs. At range of 5,000 yards, identified ships as one large tanker and large passenger-freighter of about same tonnage, both heavily loaded. Used small amount of periscope.
2241 Targets presented nice shot, bow to stern, with ½ ship length of open water in between.
2244 Saw passenger-freighter dropping back so swung right for 80 P track and fired 6 torpedoes, point of aim tanker's bow, total 11 deg spread, 8 sec interval, gyros 3R-0, depth 12 feet. As torpedoes were fired it was realized that these should have treated as two separate targets. 1 min, 24 secs after firing, heard first of three distinct torpedo explosions 8 seconds apart and saw and heard tanker explode and begin to settle by the stern, swinging slowly in our direction. Hits by #4,5, and 6 on the tanker, misses by #1,2, and 3 meant for the passenger-freighter. Pandemonium now reigned, with the tanker and escort, and possibly the passenger-freighter all dropping depth charges and firing guns. Heard one heavy explosion which sounded like boilers. Passenger-freighter now turning towards and heading down torpedo tracks, coming up starboard side of tanker, increasing speed, presenting 30 P angle on the bow. Swung right for stern shots and kept the periscope up, watching passenger-freighter and tanker and looking for escorts. Escort's screws getting louder and depth charges getting closer, but still could not see it on a sweep. Must be in-line with the passenger-freighter, now coming in fast.
2252 Fired 4 stern torpedoes at passenger-freighter, 50 P track, range 800 yards, speed 12 knots, total 4 deg spread, 8 sec interval, depth 12 feet, gyros 10R-1R. Thirty-five seconds later heard first of three solid torpex hits about 8 seconds apart, immediately followed by a devastating explosion which shook SUNFISH so severely that members of the control party were thrown off balance. Coinciding with this explosion, observed a tremendous shower of flame, sparks, dense black smoke, steam, and pieces of ship from amidships of passenger-freighter, which extended skywards at least 200 feet. Saw that the tanker was now under. Saw escort coming in fast on our port beam, and close, small bow angle, appeared to be a HIDORI. Saw that passenger-freighter had stopped and was settling fast so rigged for depth charge and went deep. At 100 ft, escort dropped a pattern of 4 charges astern, then started several fast runs, dropping charges each time, none too close. During this time, loud, unmistakable noises of the passenger-freighter breaking up were heard throughout the boat; noises like nuts and bolts being dropped on our hull, accompanied by numerous thuds and low order explosions for about 15 minutes. Only an occasional depth charge now. Total of 25 depth charges were dropped by all vessels, no damage.
Aug 14, 1943.
0055 Commenced reload and at 0140 when escort screws faded out, started for periscope depth.
0219 Surfaced in bright full moon. All clear, set course for area. Sent report to COMSUBPAC estimating 18,000 tons probably sunk.
Aug 16, 1943.
1000 Sighted overturned metal lifeboat, cans, boxes, and floating wood.
1130 Starboard lookout and J.O.O.D. sighted periscope on starboard beam, distance 3-4000 yards. Put it astern and made ready after tubes but it was not sighted again.
Aug 22, 1943.
2042 Sighted smoke bearing 040 T. Headed towards it and at 2100 had radar contact on large group of ships, 16,900 yards. The TBT could stay on one target. Ranges varying from 10,000 to 18,000 were obtained with bearings 20 deg on either side of estimated convoy center. This is an approach officer's nightmare.
2140 Convoy now tracking on course 165 T, speed 8-12 knots with SUNFISH on starboard beam so maneuvered for position ahead. Visibility was improving and 10 or 12 ships were counted. Decided on a moonlight periscope attack that would give us time for more accurate data and allow for target discrimination.
2309 In position ahead, commenced closing. At this time the convoy seemed to go into a huddle and come out on course 270 T, speed 9.5 knots, so maneuvered to get ahead.
Aug 23, 1943.
0150 When ready to submerge for attack found that convoy had zigged to new course 230 T which placed us too far off the track for a submerged approach.
0300 Again in position ahead, but visibility was such and dawn so near so decided on daylight submerged approach.
0447 Daybreak, convoy in sight, range 24,000 yards. Dived on track and headed in.
0530 SUNFISH in position dead ahead and between two starboard columns. Decided to attack these.
0711 When the convoy was 10,000 yds out all ships zigged 60 deg left to 170 T and reformed ranks on the two port columns, coming out of the huddle in a loose "T" formation, two loose columns of 4 ships then capped by 4 ships abeam in the rear, with a MINEKAZE class destroyer 1000 yds ahead and between the two leading ships, and a small 800-1000 ton trawler or freighter (pinging) close stern of the last four ships. (This convoy commander either is a former submariner or played football for U.S.C.!)
0757 Convoy again zigged, new course 220 T.
1243 Surfaced for chase.
1832 In position abeam, closed to keep masts in sight.
2015 In position ahead, 6,000 yds from track, commenced closing at 5 knots, on opposite and parallel course, 2 engines on propulsion.
2038 Sea was glassy smooth. It was too dark for an intelligent periscope approach on multiple, scattered targets and it seemed too light for an undetected surface approach. We had now chased this convoy 287 miles, on 4 engines a majority of the time, and had been in bad positions too frequently to risk it again, so decided on a surface attack, using slow speed to keep our wake and bow wave as small as possible. Kept our bow pointed at the DD, range 6,000 yds until we were abaft his beam, then swung right and headed towards ARIZONA MARU type AK at 5 knots. Planning on firing bow tubes at this ship and 7,000 ton AP now astern of AK, then swing around for stern shots and go out on 4 engines.
2144 Having swung for attack on AK (range 5,200 yds, 60 P track) destroyer evidently sighted SUNFISH or thought he saw something in our direction, flashed a signal to the convoy and headed towards us. Sped up to 10 knots to get close to AK before destroyer got too close to us. Now observed trailing escort also heading towards us.
2150 Our course normal to convoy's, range to large AK 3800 yds, gyros already left and too large, saw there was not time to swing left for a shot at AK with DD now broad on port bow, and big as a barn. Trawler broad on starboard bow, closer than DD, so shifted to 7,000 ton AP astern of AK and fired three bow tubes #1 and #2 torpex, #3 TNT, 1 deg spread, range 3,800 yds, gyros 10-12 L, 8 sec interval. Immediately ordered full speed on 4 engines, hard right rudder and shifted radar to DD. Range 2500 yds and then 2300 yds in a few seconds. Range to trawler 1500 yds.
2151 Dived, but had difficulty getting down with full rudder. As we went down, sound, who had been ordered to stay on DD during approach, reported a torpedo blanking out DD's screws. This was not one of ours; must have been from DD. 2 minutes and 23 seconds after firing heard a good solid torpex hit and 8 seconds later a second equally loud hit followed in less than one second by a tremendous distant explosion which shook the boat. This sounded like a boiler explosion. Less than one minute later, 2 depth charges, close but less violent than the previous explosion.
2158 Three depth charges, not close. DD and trawler could be heard passing overhead, one of them pinging. Found a density layer at 230 feet. Trimmed at 300 feet.
2215 Trawler overhead a good part of the time. We are thankful for having such a valuable instrument as the bathythermograph to indicate density layers.
Aug 24, 1943.
0125 Pinging and screws faded out.
0140 Surfaced, all clear. Sent contact report and headed for our area, recharging batteries. Decided not to continue chase because: (a) convoy had 40 mile head start: (b) probably had changed base course radically, since there were several choices of routes.
Aug 28, 1943.
2205 O.O.D. sighted what he thought to be torpedo track crossing ahead.
2345 SJ radar contact 1100 yds, broad on starboard beam. Avoided; SJ contact lost 1t 1550 yds. Nothing seen in the poor visibility.
Aug 29, 1943.
0052 Sighted greenish-yellow flare at 155 T.
0110 Sighted flashing light on horizon 230 T.
0112 SJ contact board on port bow, 013 T, 1000 yds. Nothing seen so headed towards and dived with O.O.D.'s torpedo track still in mind. Nothing heard for several minutes, then at 0130 sound heard faint noises ahead that developed into a light fast screw that faded out at 0230. Due to hazy weather none of these mysterious adversaries was ever seen.
Sep 3, 1943.
2337 Radar contact on another large ship, 14,000 yds and 6,000 yds beyond (to eastward), 20 deg to left (northward). Had to do some broken field running as we dodged lighted sampans during the approach.
Sep 4, 1943.
0008 Range 3000 yds, but visibility so poor target still not seen. To ensure hitting a lightly loaded ship set depth 8 feet. At range 1,900 yds, outline of large ship seen by Commanding Officer and O.O.D. on the bridge. Target was not smoking; stack could not definitely be seen. At this late point was reluctant to chance any confusion by ordering deeper torpedo depth, so crossed our fingers against any prematures and at,
0014 Range 1,700 yds, on 90 P track, fired 4 bow torpedoes, depth 8 ft, 5 deg spread, gyros 10-15 L, 8 sec int, two center torpedoes torpex, two wing torpedoes TNT. Observed #2 start zig-zagging, them straighten out and head for the target. 1 minute 24 seconds after firing heard and saw #2 hit amidships and 3 to 4 seconds later heard and saw #3 hit slightly aft of #2. #1 and #4 apparently missed ahead and astern, or were duds. Both hits illuminated the target and revealed a large AP, with a single fat stack, large, long superstructure, cruiser stern, built along modern lines, estimated at 10,000 tons. Commenced tracking second ship, leaving TDC on one just attacked.
0019 Tracked second ship making a run for the beach just 12 miles distant, making good speed. This places SUNFISH astern so abandoned chase, opened up to westward, and get clear of inevitable escort.
0020 Range to first target 3000 yds - a heavy explosion which literally picked up SUNFISH, moved her over a few yards, and set her down again. Simultaneously observed towers of flame and sparks from the target; probably boilers going up. Was quite certain that target would sink so opened out to westward on 4 engines.
0025 A heavy barrage of depth charges and estimated 5 inch gun salvos from a point 20 deg to the right of target. This was the noisiest escort ever encountered. He had an abundance of ammunition and depth charges and he expended them freely.
0027 Range to target 6,000 yds, still stopped and fading out rapidly on radar screen.
0030 Target no longer seen on radar screen. It is considered that this target sank about this time. Assuming that the loud radio signals heard over net came from target, indications are that the target sank about 0032 by radio room clock, with enemy radio operator staying with his transmitter to the last. Conclusion by the Commanding Officer is that this ship definitely sank.
0041 DD still dropping depth charges and firing broadsides in our direction (our wake looked like Times Square before a blackout). Our disappointment in not getting the second ship was tempered by the certainty that our target sank and by the comfort of knowing SUNFISH was out from under what sounded from a distance like a terrible working over for the fish in that vicinity. Patrolled to southward long PESCADORES-DUTCH EAST INDIES-SINGAPORE routes.
Sep 17, 1943.
Patrolled along IWO JIMA and KITO JIMA along track of first convoy attacked.
Sep 18, 1943.
1149 Saw large freighter, zig-zagging on 290 T, speed 9.5 knts.
1510 Sighted submarine dead ahead 000 T, 5 miles, small starboard bow angle closing rapidly; also sighted another unidentified vessel astern of submarine. Submarine looked like one of ours through the periscope. Dived, headed for freighter's track; this course put submarine on port beam. Range now 24,000 yds. Saw nothing more of submarine or vessel astern even though planed up to 10 ft periscope exposure.
1610 Sighted two OTORI's and small freighter astern of target. Target now identified as similar to TAIGEN MARU (5,660 tons), lightly loaded. Sea was dead calm, except for heavy ground swells.
1631 Range to large AK 5,000 yds, sound picked up AK's heavy screw (80 rpm). Now observed, for the first time, two OTORI's, one 1,000 yds ahead of AK, the other, 1,300 yds on starboard beam of AK, latter pinging.
1646 In position 1,000 yds on starboard beam of freighter, 105 stbd track. Pinging OTORI now astern of SUNFISH 300 yds. Fired 3 remaining bow torpedoes (TNT) at AK, 5 deg spread, 12ft depth, gyros, 3R-7R, 8 sec intervals. Both OTORI's were heard to speed up shortly after firing (300 rpm) so went deep at full speed to get through density layer at 150 ft and rigged for depth charge. Sound heard first hit 50 secs after firing, a few secs later a low order explosion. Sound tracked torpedo run until depth charging began.
1649 AK's screws stopped and were not heard again.
1649.07 Heard the first of two heavy explosions, not depth charges. Immediately followed by loud thuds and metallic banging heard throughout the hull.
1650 First of 40 depth charges, the first 30 of which were very close and violent. Thought that the conning tower would rip off. Both OTORI's running overhead, alternately one forward and one from astern. Apparently have us well located and are taking turns. These were definitely first team escorts and seemed to have no trouble locating SUNFISH though we were at 250 ft with the bathythermograph registering a heavy density layer at 150 ft. Evasive tactics consisted of trying to keep them astern, using 40-80 rpm's, speeding up immediately after each pattern.
1655 More depth charges that were large and close, shaking us up considerably, breaking lights, knocking cork off hull, causing pointers of gauges and electrical motors to hit the pegs, knocking filler caps off of battery cells, opening various valves, jarring main motor control switches out of position, and doing other minor damage. In the first 5 minutes, took 14 depth charges, close. During another 5 minutes, took 16 depth charges, close.
1716 Last depth charge, making a total of 40 in 26 minutes, the first 30 all close. Later patterns were all set deep and it was necessary to speed up to hold the boat down.
1726 Two escorts now heard pinging, slow speed, apparently searching. They used long and short scale, with single, double, and continuous pings.
1809 A heavy explosion, lacking the preceeding "click" of a depth charge, which was prolonged and accompanied with a hissing sound. This had the characteristic of a boiler explosion.
1828 Another heavy, prolonged explosion, immediately followed by loud, sharp crackling noises on the sound gear for three minutes, on approximate bearing of target if still stopped. These crackling noises were identical to those caused by ships previously known to have sunk.
2027 Surfaced, all clear. Cleared vicinity and resumed course for Midway. Since this convoy consisted of only one worthwhile ship, believed sunk, did not send contact report.
Sep 19, 1943.
Had a fire in main control cubicle upon surfacing this date. Caused by loose cork from depth charging.
Sep 25, 1943.
0830 Arrived Midway.

Hits were followed by 2 explosions 3 secs apart and metallic breaking up noises were heard throughout the boat. First sounded like a boiler explosion. The second was followed by loud, sharp crackling noises on sound gear for 3 minutes. At 2 hrs and 41 mins after firing, escorts still in vicinity but AK was not in sight."
Captain's remarks:
Lt Cdmr Fred Connaway, USN, making his PCO patrol, was a valuable asset to the ship and a great aid to the Commanding Officer. He seemed to have the happy faculty of knowing exactly what was wanted and in being in the right spot at the right time. This is the second consecutive patrol made by this vessel with but one qualified ship's officer besides the Commanding Officer. Lt Cdmr Connaway rounded out the complement very nicely.
5TH WAR PATROL, COMMENTS ON:
The fifth war patrol of the SUNFISH was conducted in the BONIN islands in the east China Sea. The major part of this patrol was severely handicapped by extremely inclement weather. This reduced area coverage considerably and, likewise, reduce the number of contacts. Only two contacts worthy of torpedo attack were seen and these could not be closed. (J.H. BROWN, Jr.)
It is regretted that continuously heavy weather prevented better area coverage and that the patrol was so unproductive. (C.W. STYER)
The SUNFISH's fifth war patrol lasted for 59 days, of which, about 37 days were spent in and near the patrol area northeast of FORMOSA. Heavy seas, gales, and poor visibility were encountered for considerable periods of time and reduced the effectiveness of the patrol. On one occasion navigation was by dead reckoning for five consecutive days! The two AK's could not be pursued as they were closing nearby islands and the carrier task force could not be closed to torpedo range. (K.G. HENSEL)
Oct 16, 1943.
1500 Departed Midway Island.
Oct 22, 1943.
0829 Sighted 2 aircraft headed for SUNFISH. Identified as Type 97 Mitsubishi flying boat. Second aircraft was Type 97 Mitsubishi torpedo bomber. Dived. Decided to remain submerged during daylight in attempt to elude persistent and alert aircraft patrols.
Nov 1, 1943.
Received dispatch directing us to proceed to new area. Progress was limited by heavy storm from north which reached maximum intensity when a large wave broke over the bridge. Considerable water was taken down the conning tower hatch on down to the bilge's and fortunately no electrical equipment was grounded out due to the alertness of the control room watch.
Nov 7, 1943.
Underway to OKINAWA GUNTO.
Nov 16-21, 1943.
SUNFISH experienced worst storm of her career beginning early in the morning of the 16th and increasing in fury until it was impossible to maintain a periscope watch. Mountainous seas with 40 to 50 foot waves. Winds were 50 to 70 knots. On the night of the 16th, the after lookout was washed onto the main deck by a heavy wave. It was considered unsafe for lookouts to take their station so two officers stood the bridge watch.
Nov 25, 1943.
0600 Sighted smoke and masts on horizon bearing 320 T, distance about 12 miles. Commenced approach.
0700 Targets identified as two AK's 3-5000 tons, on course 070 T. plot of their track showed that SUNFISH had been 20 miles ahead of them before daybreak.
0830 Unable to close targets closer than 7m miles. Broke off approach.
0945 Sighted Type 97 Navy torpedo bomber bearing 100 T distance 3 miles on northerly course. Plane carried three bombs or depth charges where torpedo was normally carried.
3 Dec, 1943.
1007 Sighted task force consisting of 2 carriers and 2 or more destroyers bearing 100 t, distance 10 miles. Commenced approach. Base course 340 T, speed 19 knots.
1030 Unable to close targets closer than 12,000 yards so broke off approach.
14 Dec, 1943.
1230 Arrived S/M Base, Pearl.
6th WAR PATROL, COMMENTS ON:
The sixth war patrol of the SUNFISH was conducted in the Caroline and Marianas Islands. Sunfish also accomplished, in an excellent manner, a photographic reconnaissance of TAONGI Atoll and KUSIE Island. In spite of heavy air patrols, SUNFISH covered her assigned areas thoroughly and was able to launch four aggressive and tenacious attacks. Three attacks were made on one ships which resulted in ultimate sinking. The first attack was made on an unidentified Japanese aircraft carrier. The COMMANDER SUBMARINE FORCE, PACIFIC FLEET, congratulates the Commanding Officer, officers, and crew for this outstanding and aggressively conducted war patrol. (C.A. LOCKWOOD, Jr.)
SUNK:
1 - Aircraft Carrier (Type unk) - 25,000 tons
1- Freighter (KAMOI MARU class) - 5,356 tons
30,356 tons
This outstanding patrol, a high point in submarine warfare, was the first patrol for the Commanding Officer (E.E. SHELBY).
The Squadron Commander adds his heartiest congratulations for this courageous and exceptional performance. (R.E. BLUE)
SUNFISH's sixth war patrol will long live in the annals of submarine warfare, resulting in the sinking of a Jap CARRIER on the anniversary of the birthday of George Washington. This was a 52 day patrol with 31 days spent in the patrol area. The carrier was tracked and sunk in a night surface attack under the most adverse conditions of heavy seas, spray, and rain squalls. After determining that it was stopped or nearly so, SUNFISH headed in, saw a cloud of smoke over the carrier when finally sighted, and fired six bow tubes with a run of 2,100 yds. Three to six hits sank the flattop in 13 minutes. A few minutes later, another contact was made resulting in three attacks and the sinking of a large freighter that was making 2 knots nearby. In the first phase, one hit was made from 3 down-the-throat shots, stopping her. Then 3 more at 1,100 yds got two hits forward. SUNFISH dived due to aircraft contacts in the pouring rain, more SD contacts while attempting to surface after daylight, and after surfacing, sank it with one stern shot at 800 yds. (K.G. HENSEL)
15 Jan, 1944.
1110 Departed Pearl for Midway Island.
18-19 Jan, 1944.
2400 Enroute area.
4 Feb, 1944.
0835 Ship contact. Range 17,000 yards. Appears to be a hospital ship with markings. Started end around to examine ship.
0920 Definite hospital ship. Decided to close and take photographs.
1050 Ship identified as HIKAWA MARU (second time that she has been closed by this vessel).
17 Feb, 1944.
0918 SD contact closed to 8 miles. Dove.
1018 Believed we were strafed at periscope depth.
1210 Believed we were strafed at periscope depth.
1259 Surfaced; SD contacts at 20 to 30 miles. Listening to our own planes on VHF. (By this time had heard over 200 heavy distant explosions as of bombs or depth charges, not counting the practically continuous explosions similar to 20MM fire from shells exploding on or in the water).
18 Feb, 1943.
0853 High periscope ship contact. Started tracking and gained position ahead. Target's steady course suspicious.
0920 Dove and commenced approach.
1015 Ship made out to be a hospital ship. Crew's unanimous opinion was sink the thing anyway; two hospital ship contacts, and nothing else, is too much to stand.
1025 Took pictures of ship at 900 yds.
23 Feb, 1943.
0015 Heard what sounded like two torpedo or depth charge explosions far away, apparently to the north.
0200 SJ contact 355 T, 20,000 yds, big pip, commenced lobe switching at this range. Started closing. From this time on the radar operator, with the assistance of the approach party, turned out the most remarkable job of radar tracking under the worst possible conditions.
0258 SJ contact on small ship on starboard bow, 5,200 yds.
0300 Tracking had shown target on various courses, at speeds never greater than 4 knots, bearing remaining practically constant. Pip tremendous at 7,000 yds. Conclusion at this time was that ship was circling. Decided to close straight down bearing and make setup on sight contact.
0312 Escort range opening and slowly drawing aft.
0312.40 Sighted large blur on stbd bow with what looked like a cloud of smoke laying over it. Range 5,350 yds.
0317 Heading directly for target, escort closing range rapidly.
0325 Target bearing remaining steady, got a brief glimpse at 3,700 yds. A big ship with smoke overhead. Then heavy rain.
0331 Rain shifted to a drizzle, got first good look at target at 2,560 yds. Aircraft Carrier with a 50-60 deg port angle; large cloud of smoke hanging low overhead under low clouds.
0332 Held rapid debate; decided impossible for one of our carriers to be here. Thought most probable that carrier had been damaged by explosions heard around midnight.
0334.24 Commenced firing spread of six with ½ deg btwn torpedoes, own speed 5 knots. Torpedo run 1st shot, 2,100 yds. Increased speed and started swinging with last shot to bring stern tubes to bear.
0336.09 Impossible to say how many hits. C.O. felt two distinct shocks (those below-decks felt three) before noise and shock of seemingly one explosion blended everything together. The center of the target erupted in flame, smoke, and debris flying two to three times as high as the ship. The explosion was somewhat continuous as debris continued to erupt skyward.
0340 One terrific explosion (no flame or flash seen) of long duration. the shock from this explosion jerked the boat in the water, and the blast snapped the heads of the personnel on the bridge causing them to have to take a step to maintain their balance.
0341 Following this heavy explosion there was two or three explosions close together that sounded similar to torpedo explosions. Their time corresponds with the end of run explosions and possibly two or three torpedoes missed; although this seems impossible considering length or target, small spread used, and the fact that the first torpedo hit center of target.
0342 Radar reported pip getting smaller. Started reload forward.
0349.30 Radar pip completely gone. Radar range at 5,000 yds at disappearance. Closing last target bearing; escort turned away, range opening rapidly on direct bearing for SAIPAN.
0354.15 Picked up fairly large radar pip, 17,000 yards, 17 deg farther south than last bearing on carrier pip. Started closing and tracking with rush reload job going on forward.
0439 Sighted object dead ahead, 3,400 yds. Careful scrutiny caused unanimous conclusion it was the bow of the carrier projecting vertically up out of the water. You could hear the cheering below decks through the hull.
0441 TBT officer, (long merchant marine experience), broke the illusion with report, "That's a freighter bows on." Range 3,000 yds. Headed directly for him at 1/3 speed. 5 knots.
0449.20 Started firing down-the-throat shots. First torpedo came out and steadied on a course about 15-20 deg to the left. Second torpedo wake indicated it was going to miss slightly to the left. Target appeared to start a turn to the left. Fired a third at 1,500 yds; sped up and turned to the left to keep bearing ahead. C.O. did not feel a hit, everyone else says one hit by second or third torpedo. C.O. refused to believe it.
0505 Sighted target in the rain, range 1,450 yds. Ship appeared dead in the water. Later concluded crew were abandoning ship at this time, as there was no crew aboard when ship was sunk much later.
0507.40 Fired spread of three remaining forward torpedoes, 1 deg spread, run 1,100 yds.
0508.25 Saw and felt two hits, one on bow and one just forward of bridge. Raining so hard could not see target at 700 yds.
0525 SD radar contact. Dove. Made circle around target submerged.
0551 Heard distant explosions, depth charges or bombs, estimated 1-2 miles away.
0640 Sighted target with bow blown off at the bridge, bearing 228 T, drifting with the wind. Started closing.
0730 Closed target sufficiently to make out details of Jap freighter with the bow blown; down only slightly by the head. Japs build good ships.
0749 Wanted to get on surface for lifeguard calls although with heavy rain doubtful raid is going on.
0813 Slowed for a look at target when three bombs fairly close. Toss up - are they ours planes finishing off our ship or Japs bombing us? Rigged for depth charge. Three bombs much closer. Our boys are either poor shots or they are Japs. Three more alongside and one astern. Went deep. 4 more close while passing 80 feet.
0820 Last of 27 bombs.
0825 1 bomb - machine gun fire.
0840 Periscope depth, target afloat and undamaged any further, must have been Jap planes.
0845 Surfaced, target 1,500 yds.
0846 Established communication with our planes and examined target. Decided it would take too long to sink with 3" gun. We were in a hurry to close our lifeguard station 9 miles distant. No sign of carrier. Wreckage and oil slicks strewn over area as far as could be seen.
0907 Swung in across missing bow of freighter at:
0909.40 Fired one stern torpedo, 800 yds, 8ft setting, to hit under stack. It worked like a clock. Every ship should get a shot like that for part of the crew to see. We took movies and photographs of it; hope they are good.
0915 Proceeded at full speed to lifeguard station.
1045 Sent my 222310 to CSP. (Comm Stat Pearl) VHZ received it but would not receipt nor answer afterward. Radioman is suspicious that a Jap told him to send it to him.
1258 Received first report of downed plane. Went to battle stations and rescue stations. From this time until 1626 spent time searching five out of six positions reported.
1415 Smoke from fires piling up under clouds and blanking out view of SAIPAN and TINIAN from view.
1525 Received last report (a repeat), and this was the last voice radio heard from our planes.
1615 Sighted 9 two-motor bombers coming from N.W. They passed about 10 miles N.E. of us and landed on TINIAN. Jap eyesight must not be so good.
1620 High periscope ship contact, bearing 232 T, heading for SAIPAN. At this time we were about seven miles off of the coast of TINIAN and in plain sight. The approach of an apparently large vessel seemed suspicious. This was not an appropriate time; the Japs could not be sure that the raids were not over and they well knew submarines were present.
1626 Dove, started approach. Target appeared to be using moderate zigzag plan towards SAIPAN harbor.
1715 Saw complete target, hull up, for the first time. Made vessel out to be a Q-ship. Description contained in "Anti-Submarine measures" section.
1718 Sighted two float planes circling Q-ship.
1732 Q-ship abandoned zigzag and headed straight for our diving point. Closest we got was 4,000 yds, 120 deg P track.
1825 Q-ship changed course to 250 T and heading for position I wanted to reach. Both seaplanes now searching entire area, making no pretense of covering track of ship.
1845 Last look at Q-ship, which was searching wildly to eastward courses in approximate vicinity where I dove.
Feb 29, 1944.
Enroute Pearl Harbor.
Mar 7, 1944.
1115 Moored in assigned berth, S/M Base, Pearl Harbor, Territory of Hawaii.
Torpedo Attack #1 was delivered at 1735, 22 Feb, 1944. Location was: Lat 15-23N/Long 45-02.5E. Target description: Silhouette at night at 2,000 yds, 90 deg port angle, most clearly resembles SHOKAKU class carrier, 29,800 tons. Length estimate varies from 800-1,000 feet. Target draft 15 ft/Course 326 T/Speed 1/2-2 knts Range 2,100 yds. Observation: "Saw continuing series of explosions and center of ship erupted 2-300 feet into air. C.O. felt first and second shocks, below decks felt three. At 5 minutes, 45 secs, a terrific explosion rocked the boat and the blast knocked personnel off balance. At 7 minutes, immediately after last explosion, radar showed pip getting smaller and completely gone in 15 minutes. There was no sign of the carrier at daybreak 2 ½ hours later, nor during search of area subsequent to second attack."
Torpedo Attack #2,3,4 was delivered at 1849, 1907, 2309, 22 Feb, 1944. Location was: Lat 15-20N/Long 145-02.5E.
Target description: AK (KAMOI MARU class) Target draft 15 ft/Course 333 T/Speed 2 Range 1,400 yds. During second attack target speed dropped to 0 and range was 1,100 yds at time of firing. Observation: "On first attack, heard one hit. On second attack, saw two torpedo hits, one just fwd of bridge and one on bow. Later saw ship with bow blown off. On third attack, saw one hit center of target and ship sunk."
C.O.'s final patrol comments: "The statement 'Action builds morale' has certainly been proven. After a long, almost despairing wait for a contact, the night action one day prior to leaving station put every one in the highest spirits and left them impatiently awaiting another target. Being present and witnessing the courageous and effective work of the pilots who carried out the airstrike was an inspiration to us all. All hands deeply regret that we were unable to find and rescue the pilots who were forced down during the raid."
7th WAR PATROL, COMMENTS ON:
The seventh war patrol of the SUNFISH went from 22 Jun to 1 Aug, 1944, in the Kuriles Islands Area. In spite of fog, the SUNFISH was able to conduct a thorough area search for enemy traffic. The SUNFISH carried out well-planned and aggressive torpedo attacks against two enemy independents and one escorted convoy. In addition, an outstanding gun battle was fought against a fleet of sampans and armed trawlers which resulted in the destruction of 13 sampans and one large trawler type patrol vessel. This battle was an excellent example of the proper use of all weapons. (M. COMSTOCK)
SUNK
1 - Freighter (DAIBOSI MARU NO. 6 Class) 4,000 tons
1 - Freighter (Class Unknown) 4,000 tons
1 - Large freighter (Class Unk) 7,500 tons
13 - Sampans 2,500 tons
1 - Trawler patrol vessel 500 tons
18,500 tons
DAMAGED
1 - Freighter (SEIA MARU class) 6,600 tons
Area coverage by the SUNFISH was excellent, most of it being on the surface under conditions of poor visibility, depending almost entirely on SJ radar. This patrol was characteristic of the previous patrol by this Commanding Officer in that it was most outstanding every respect. The aggressiveness and tenacity displayed throughout, in spite of fog and cold weather, are exemplary. The attacks on four merchant vessels were well planned and aggressively carried out. The gun battle on 7 July, resulting in the destruction of 14 ships for 3,000 tons, is one of the most outstanding submarine performances of the war.
Torpedo Attack #1: Three torpedoes were fired on the surface at an anchored unidentified target similar to the DAIBOSI MARU. The third torpedo was seen to hit and the ship was seen to sink.
Torpedo Attack #2: In a night radar surface attack, one hit was obtained with three torpedoes fired at a medium sized unidentified freighter. The attack took place at 0004 on 6 July, in foggy weather. Ship was not sighted until range had closed to 1,200 yds. Radar pip disappeared in 90 seconds, ship was heard to break up, and Jap survivors sighted in life rafts.
Torpedo Attack #3: Two salvos of three torpedoes each were fired from periscope depth at two ships in a convoy consisting of three merchantmen escorted by two FUBUKI class destroyers. One hit was observed and a second hit timed in the first target, which was a large unidentified ship. A severe depth charge attack prevented further observation of this ship or of the results of two timed hits in the second ship, a medium freighter of about 6,000 tons. Breaking up noises were heard from both ships.
Deck Gun Attack #1: On 7 July, the SUNFISH destroyed thirteen sampans and one armed trawler for a total of 3,000 tons in one of the most outstanding gun battles of the war. (Later called by CINCPAC as, "the best gun action for a sub in the entire war.")
The aggressiveness and control of the situation displayed by the Commanding Officer in this "melee" is most outstanding. The fire control necessary to engage as many as five sampans at one time speaks for itself. The SUNFISH brought the following guns to bear during the engagement:
(1) 4".50 cal Deck Gun
(2) 20MM cannons
(2) .50 cal machine guns
(2) .30 cal machine guns
(2) .30 cal BAR's
The outstanding performance of duty of V.V. McCLANAHAN, MoMM2/c, USN and T.L. ALDRIDGE, SC2/c, USNR during this engagement were noted by the C.O.
Jun 22, 1944.
1330 Departed Pearl Harbor for area, via MIDWAY.
Jul 3, 1944.
1200 Entered area, 60 miles from Paramushiru To, by DR.
Jul 4, 1944.
1132 Sighted small fishing boat, distance 3 miles, looked awash. Manned 20MM guns and closed on chance it was manned. Closed to 20 ft and boat was not manned.
2200 Decided Japs weren't moving through 4th strait; will patrol up coast to NE and be off Paramushiru Strait by day break.
Jul 5, 1944.
1238 Sighted masts of ship (not smoking) about 3 miles north of beach. tracked it as if stopped or anchored. Worried about shallow water but decided to go in on the surface using fathometer and identify ships. They appeared to be anchored well offshore, off coves. Went to battle stations.
1313 Made out Russian identification on one ship, an old freighter of about 3,500 tons. Headed for northern ship which showed no colors or markings.
1340 No guns, markings, flags, etc., visible. Range 4,000 yds; fathometer showing 15, slowed to 1/3 speed, rigged searchlight and started challenging with AA signal (My DAD was on the signal light) while heading in on a 90 deg track. (In past experience Jap escorts have always challenged with AA signal) Situation unusual; ship not ID'd, probably just inside territorial waters, and showing no colors. Continued challenging and closing. Much scurrying about the ship, apparently getting up steam as she started smoking. Ship was in a quandary as he had seen us bows on and did not know what to do. At 2,000 yd range, the Japs nerve broke and he ran up Jap colors on his after flag staff. The "color raiser" then tied something white to the pole and started waving it furiously from the after deck house.
1349 Fired first torpedo at 1,500 yds, 10 ft depth, and watched wake run directly under stack. This torpedo laid a regular smoke screen.
1350.30 Fired second torpedo at 6 ft depth, range 1,100 yds, and started swinging left to clear. Wake passed under ship about 20 ft aft of stack; this may have been a dud as several men heard a thump at correct time although no disturbance in the water was seen. We looked and felt silly. Steadied, and at 1,100 yds.
1356 Fired torpedo set at 5 ft. This one laid down a regular smoke screen, but at,
1356.50 Hit, just aft of stack. Ship sank in about one minute. Cannot account for first two torpedoes passing under, especially #2 at six feet. Ship was partially loaded, and it drew at least 12-14 feet.
1440 SJ radar contact. Contact in fog, sub in the clear, 220 T, 12,000 yds, commenced tracking. Finally made out small ship in edge of fog. Started end around.
1504 After periscope inspection made him out to be small 600 ton coastal gun boat, PG-5. Secured from end around and decided to proceed north and investigate northern route across sea of Okhotsk.
2312 SJ radar contact, 18,700 yds, 325 T. Commenced tracking, visibility 1,000-1,500 yds. Large pip. Tracked at 9 knots. Closed to 1,000 yds off track on last leg, stopped and waited for ship to close. Zigzagging indicates a Jap. At 1,200 yds just made out a dim shape. Saw a vertical bar of light when a door was opened and then shut; that made it positive, if any nav lights were burning I would have seen them. Got final set up and at,
0004 Fired first torpedo, run 900 yds. Just after second torpedo was away, saw door on target open again and target sounded a short "toot" on air whistle. Fired third torpedo. Hit at time for second torpedo run. Followed by short series of explosions; breaking up noises heard on bridge. Radar pip gone in 90 seconds. manned 20MM and closed area. Sighted large oil slick and wreckage over area. Closed rafts and observed Japs on rafts; heard much moaning and sing-song shouting Jap. Decided against picking up prisoners so early in the patrol.
Jul 7, 1944.
1213 SJ radar contact, 110 T, range 4,800 yds, two small pips. Started tracking on 290 T, targets on course about 230 T, speed 8 knots.
1216 Came out of fog and went to 040 T to get back into fog; would have to investigate them abeam or astern. Lost contact at 6,000 yds. Closed again; fog settling in nicely. Regained contact and started trailing astern at 4,000 yds. SJ reports 3 to 5 in a group, sometimes more, sometimes less. Visibility less than 1,000 yds. Battle stations surface manned; commenced closing to pass within 700 yds of largest pip. Decided to take the port one first and as they turned away come on ahead of them and try to herd them in a circle. SJ range 800 yds; fog really thick. Closed.
1347 At 500 yds sighted 250 ton sampan about 25 deg on stbd bow. At same time lookouts began reporting three more from stbd bow to quarter. Began divided fire. Immediately ran into the center of a group of fire more ahead and across the port bow. Developed into a nice melee with us doing much circling until the entire group, including the large flankers was wiped out. Three large ones tried hard to ram us and a couple of smaller ones also tried to ram us. We sank 12 of the 14 and left the remaining two completely wrecked and riddled at the waterline, gradually sinking.
1544 After making several circles through wreckage, failed to find any of the survivors that we had previously sighted on the wreckage. Secured from battle stations surface and resumed patrol down the coast to the SW. Our damage appears to be one bullet hole in periscope shears and one antenna shot down.
Jul 9, 1944.
0936 SJ radar contact - 3 pips, 310 T, range 15,650 yds. About 20 miles north of Araido To. Started tracking, closed to 11,000 yds. Five pips on screen. Fog began to thin out.
1000 Sighted one FUBUKI class DD in edge of fog, swinging radically from right to left. Base course of convoy 120 T, speed 11 knots. came to 090 T and continued working to get ahead.
1012 Visibility quickly increasing. FUBUKI in plain sight and it was apparent that we would soon be sighted, so made quick dive and continued approach. Made out leading FUBUKI in periscope at 7,000 yds. When FUBUKI was about 4,000 yds could make out three freighters in line of bearing, about 1,000 yards apart. Leading FUBUKI was patrolling radically across bows of leading ships and a second FUBUKI was doing the same astern of convoy. FUBUKI's making 15-17 knots. All ships heavily loaded; very little freeboard. Zigging together.
1039 Target zigged to left to 060 T. Position not good; way outside. Set up on leading freighter range 3,600 yds. It was an extremely long freighter and very heavily loaded.
1050 Targets back on 115 T. Decided to accept situation. Final setup, 95 deg stbd angle on the bow, torpedo run 3,000 yds.
1053.10 Fired three torpedoes at large AK; Shifted set up (skipped small AK) and at
1053.55 Fired three torpedoes at medium AK, torpedo run 2,700 yds. Started coming left. Took look at stern FUBUKI; swinging to cross stern of last ship, stbd to port. Looked at second target, no zig yet; saw wakes of spread. Looked at first target and saw torpedo wakes; no zig yet. Swung to first FUBUKI, crossing ahead of leading AK port to stbd. Looked back at leading FUBUKI and saw AA shell explode in the air. FUBUKI was heeling over swinging toward, black smoke pouring out of his stack. Looked at other FUBUKI; heading right at us. Two fanning spreads, one about 20 deg right and one 35 deg left, pointed us out on a calm sea. Started deep and looked at first target, almost time.
1055.20 First hit, could just see masts, saw smoke and splash higher than mast just forward of amidships; heard second hit but did not see it as scope dipped under. Breaking up noises started immediately and were heard throughout the hull.
1055.49 Two torpedo explosions within 4 seconds of run for 2nd and 3rd of second salvo. At 240 ft we bounced off a layer while blowing negative. Stopped blowing and drove through the layer. The bathythermograph was no help as it ran off of the scale at 28 deg F. Leveled off, went at,
1059 First two patterns went off alongside and overhead. We ended up plunging down to 450 ft, 11 deg up angle, 80 rpms, holding but heavy. We had closed negative flood; had to build up pressure and open it by hand. Did not want to use safety and risk air leaks until necessary. Breaking up noises dying out.
1112 Pattern of five overhead; we had started blowing negative with the first one. This last group was certainly right where we had planned to be.
1114 Two more. Boat coming up, making 80 rpm. A cheerful note has been added; a new series of breaking up noises has started; heard on JP and in end compartments.
1115-1118 Six depth charges - sort of single drops. At 370 feet.
1120 Two good ones (Depth charges) boat pushed down to 425 feet.
1121 Two, not so close. Their listening gear must be excellent. We heard screws on the JP for short intervals when they kick ahead and through the hull when overhead. JK reported faint pinging now and then with the pinger right overhead.
1123-1152 Eight single drops, in vicinity, but believed they are off of us.
1120 Appeared that they had lost us; much pinging astern. Boat began to sweat heavily.
1243 Several not close.
1248 Several far away. Had been running WNW, keeping stern pointed towards DD's. Made preparations to surface. Planned to come to periscope depth and look the situation over and to surface if the fog had set in.
1251-1258 With no warning from sound, received 11 depth charges all very close. Two and three at a time.
1259-1317 6 charges farther away. Began to hear long range pinging on JK at 1230. We had run into warmer water at 30 deg F.
1429 Three depth charges, far away.
1439 One, far way.
2022 Surfaced, decided to clear the area to northern traffic routes.
Jul 10, 1944.
1540 Sighted life ring in water.
1542 All back full. Fire in maneuvering room. All stop.
1543 Fire out. Armature was stuck.
1621 Contactor repaired; answering bells on both shafts.
Jul 12, 1944.
0240 SJ radar back in commission. One has to make a patrol up here to really appreciate the SJ. Consider the last 28 hours as practically wasted.
1621 Sighted aircraft coming in from astern. Probably saw us. Fast dive.
1643 Two explosion. Commenced routining torpedoes.
Jul 18, 1944.
2245 Had quite a scare; phosphorescent torpedo spread had us cold; turned out to be seals, who continuously cut luminous wakes about us all night. Phosphorescent is so bad that OOD's and lookouts have to stand back as not to see bow and stern wakes and ruin their night vision. The glow of our wake at 7 knots reflects off of the low overhead.
Jul 20, 1944.
0500 Lookout sighted smoke. Large ship.
0533 Dove and made quick approach.
0559 Looks like a Liberty ship - Russian ship.
Jul 25, 1944.
1730 Maneuvered to avoid two torpedo wakes. These wakes were sighted across bow at about 120 deg track. (see war story)
Jul 27, 1944.
2200 Received dispatch from COMSUBPAC ending patrol, Enroute Midway.
Aug 1, 1944.
1043 Moored at Midway.
Detail of action, Gun Attack:
The action took place in heavy fog at ranges under 600 yards. The element of surprise was heavily in the submarine's favor. The volume of fire for all weapons was terrific. This, coupled with surprise, enabled us to clear enemy decks before their guns were manned or to clear them almost immediately after fire was opened on the submarine. The .30 cal BAR at one time stopped the fire of a machine gun that had opened fire on us. The terrible destructive power of the small guns literally cut the targets to pieces while the deck gun literally burst them apart at the seams. Control of fire was such, that, except for one period when there was too many targets, one gun of one type was fired while the other was reloaded. Hits with the 4" HC (High-capacity) completely demolished large sections of target, especially the upper works. The following types of guns were observed being employed by the sampans: .25 cal MG's and rifles, 7.7MM guns, and twin 25MM on patrol boats. Enemy fire was not effective- usually overhead or alongside in the water. Especially evident was the lack of Jap desire to fight once our fire was brought to bear on their decks. They ducked below bulwarks, jumped overboard, or were blown to pieces (20MM fire does some strange things.) The patrol boat was painted gray with a steel hull. He mounted 25MM guns both fore and aft, which he never got into action, his crews being wiped out as they manned the guns. He tried hard to ram, the 4" gun blowing him up (ammo explosion from appearance) at about 100 yards bows on. Several sampans tried to ram and in two attempts, when the ramming ship blew up, debris completely flew over submarine! Looked for survivors but they don't last long in water of 31 deg F. The performance of duty of personnel in this, their first gun action, left nothing to be desired.
***During the gun action on 7 July, 1944, the outstanding performance of duty of V.V. McCLANAHAN, MoMM2/c and T.E. ALDRIDGE, SC2/c, stood out. A separate letter requesting official commendations for these two men is being forwarded.
8th WAR PATROL, COMMENTS ON:
The eighth war patrol of the SUNFISH was conducted in the east China Sea and the Yellow Sea. Excellent area coverage was maintained throughout this splendid patrol. All contacts worthy of a torpedo attack were aggressively developed. The Commander Submarine Force, Pacific Fleet, congratulates the Commanding Officer, officers, and crew for another highly successful, fighting patrol for the SUNFISH. (J.H. BROWN)

20 Aug, 1944.
0530 Underway are in company of escort planes.
10 Sep, 1944.
1146 Extremely large convoy. Base course 240T, speed 8.5 knots. One quick count gave 21 large ships and 8 escorts. The center column of formation was comprised of three groups of tankers. All ships were heavily loaded, having unusually high decks loads. There was one CHIDORI type DE patrolling ahead of center column.
1208 Targets are back on course 240T. Closing.
1210.18 Fired #2,3, and 4 torpedoes at large modern diesel freighter, torpedo run 1,400 yds. Shifted set-up to next AK astern of target, a large old-type freighter, and at,
1211.11 Fired #5&6 torpedoes (#1 tube out of commission). First hit in first target just as tube #5 fired. Saw second hit occur in first target. Started coming left at standard speed. Debris, smoke, and water were still in the air from first hit directly under bridge, second hit directly under mainmast. Target listing to strbrd and sinking rapidly by the stern.
1212.05 Hit in second target. Shifted scope to look. Hit directly under stack and boilers must have exploded with the hit; stack high in the air and whole center section including bridge blown out. Ship sagging at about 15-20 degrees in the center. Ship could not stay afloat for 10 minutes. Lowered scope as we are finishing our turn and picking up speed.
1212.55 One timed hit for third torpedo of first salvo. Believed that third torpedo passed astern of target and hit overlapping tanker. This hit was not observed.
1215 Five depth charges close across the stern. Decided time to go deep. Went to 240 feet in 270 feet of water. Negative gradient all of the way down.
1219-1233 Breaking up noises heard on JP and in all compartments. This could only be the second target as the first one was certainly on the 270 foot bottom in 5 minutes.
1345 Forced to pump to hold depth. Thought we had gotten away with it, when at,
1355-1357 First of 21 depth charges close aboard on strbd quarter. This was a perfect drop of two overlapping patterns; almost a continuous series of explosions. In the shallow water, the boat did a veritable shimmy. No damage at all but boat writhed and wiggled like an eel. It must be the pressure waves going between us and the bottom.
1549 Screws passing astern. Escort got suspicious and hand keyed for about five minutes then worked off to the west.
1835 Heard 12 distant depth charges.
1936 Surfaced, reloaded, and commenced high speed search to cover possible enemy courses at speeds of 7-9 knots, to the south of SAISHU TO.
12 Sep, 1944.
2254 SJ radar contact. Course 016T, 21,250 yds. Speed 8.5 knots.
2354 In position 3,000 yds off track, 8,000 yds ahead. Turned up target's track until clear of escort.
13 Sep, 1944 .
0007 Target sighted by Captain, J.O.O.D, and port lookout. Appeared to be 450-500 feet long. Little or no superstructure visible. Unanimous conclusion - a tanker or ore ship.
0013 TDC set-up had not been touched for five minutes and checked perfectly.
0013.30 Fired 5 bow torpedo salvo, 6 ft depth, 1 deg spread, torpedo run 2,700 yds. Commenced swinging to bring stern tubes to bear. Phosphorescent wakes showed good spread and indicated torpedoes passed under target.
0020 Pulled out to 5,000 yds and watched target disappear into island background.
0122 Commenced closing on 120 S track. Small ship on opposite bow turned on white light.
0127 With target at 1,400 yds ahead, made out a small 50-60 foot tug. But we could not see a single thing between him and the trailing light 400 feet astern. After many harsh words at fate, we had decided we had been duped and that this spot had possibilities. Too many small craft not fishing. Also, we stood a good chance of getting our dummy target away from the beach the next night for some 4" gun treatment.
1700 Sighted floating mine at Lat 35deg 21'N/Long 124 deg 54'E.
1717 Exploded mine with 20MM gunfire.
2222 SJ contact, 133T, 23,000 yds. Commenced tracking.
2327 Target group sighted from the bridge. Convoy consists of 2 large AK's on line of bearing with two large AO's astern, zigging together. Radar shows one escort ahead, one on port side, and one on strbd side of convoy. Dead slow speed in phosphorescent water.
2342 Running very slow to allow escort to pass; swinging right to keep bow on escort. Passed up AK's for AO's. Escort past. Coming back right very slowly to attack course. Escort 15 deg on strbd bow.
2351.31 Fired first of three torpedoes, run 1,700 yds, 70S track, depth 6 ft, at large modern, squat stack tanker. Shifted set-up.
2352.00 Fired first of two torpedoes, 2,200 yd torpedo run, at large, high stack, tanker, on port quarter of first target. Started coming left and getting clear.
2352.43 The Mk 23's certainly made a satisfying bang after last night. Three hits right on time in first tanker, one a little forward of bridge, others slightly aft. Had hoped that tanker carried gasoline, however, there was a satisfying explosion accompanied by a great blast of blue-white flame and great red sparks.
2353.40 Two hits right on time in second tanker. Caused explosion similar to first target. The Japs got freehanded, expending depth charges, lights and flares. One escort started firing wildly with a 3" gun and machine gun. We started racing strbd escort with a 1,600 yd lead. Port escort shooting passing overhead and apparently scared strbd escort who veered off and obligingly turned on a red truck light so we could keep track of him. The first tanker observed to sink almost immediately in a nearly horizontal position. The second tanker is settling by the stern. Passed lead AK's at 8,000 yds and had the novel experience of hearing convoy leader sound blast on whistle for each zig. From then on, he regularly signaled each zig for us. Decided to concentrate on leading large AK.
0310.55 Fired four remaining Mk 18's aft, 100S track, run 2,650 yds, 1 deg spread, depth 6 foot. We pulled away down reverse of spread course and at proper time the target was dead astern; no hits. Second target passing in nice torpedo range. We lost contact at 35,000 yds.
0426 Transmitted, area notice #2 to subs in the area. AK's would be in SHANGHAI waters shortly after daybreak. We sure missed those nine torpedoes that we had been duped into firing night before but got some revenge.
1741 Surfaced and set course to depart area.
26 Sep, 1944.
1820 Sighted USS PIPEFISH; closed, proceeded in company.
27 Sep, 1944.
Arrived Pearl Harbor.
9th WAR PATROL, COMMENTS ON:
The SUNFISH's ninth war patrol was conducted in the Yellow Sea area. The SUNFISH, along with the USS PETO (SS265) and the USS SPADEFISH (SS411), formed a wolfpack under Commander G.W. Underwood, as the group commander. This group also performed lifeguard duty as well. The SUNFISH maintained excellent area coverage and was rewarded with numerous contacts, many of which, however, were small-craft. Despite HEAVY enemy anti-submarine air coverage, the SUNFISH was able to deliver five excellent torpedo attacks with severe damage to the enemy. It is probable that the enemy escort vessels were sunk or damaged as a result of the explosion of the ammunition ship sunk in attack #4. Unfortunately, the evidence of damage to the escorts is not sufficient to permit credit. (C.A. LOCKWOOD)

23 Oct, 1944.
1130 Departed Pearl for Midway in company of USS SPADEFISH and USS PETO.
28 Oct, 1944.
1000 Arrived Midway and took on two replacements, plus one additional man who talked both us and his squadron into letting him go.
11 Nov, 1944.
0928 Sighted first B-29 through periscope. Surfaced. During next two hours sighted 50 B-29's and had SD contact on many more. Strike was two hours ahead of schedule.
1326 Decoded CSP's 110323. Proceeded at 4 engine speed to position of ditched B-29. Japs jamming entire frequency all afternoon.
1715 Arrived at estimated position of B-29. Fired mortar star shell. Commenced box search. 2008 fired another mortar star shell.
2306 Lookouts reported a possible red star, 232T, over horizon. Started closing.
12 Nov, 1944.
0008 Fired another mortar star shell. Flashed blinker gun across bows. At each five miles run down bearing, circled, sounded whistles, and fired "Buck Rodgers" star. Sea calmer, wind down to about 20 knots. Sky clearing.
0733 Surfaced from trim dive and commenced box search.
1615 Sighted USS QUEENFISH and exchanged signals on search. She and USS PICUDA would continue search.
15 Nov, 1944.
2347 BARB informed us that an aircraft carrier and 4 DD's; no other data. Assumed 17 knots speed and changed course to 243 deg T for intercept.
0030 BARB reported one hit, and came through with new position 17.5 knots, and changed course of carrier to 025 deg. Came left to 068. (Bucking sea, best speed 18.5-19 knots) We are shooting for an intercept 10 miles ahead of carrier. We can just make it if the data is right.
0100 SJ contact 37,500 yds. Carrier about 10 miles north of reported position. Our only chance was if someone ahead and could slow or turn him. Started sending position reports every 15 minutes, BARB doing same. Somebody should be ahead. QUEENFISH reported that she was out of the race. SPADEFISH same. PETO was to the north of us at surfacing and PICUDA may have been to the north; hoped so.
0240 Target making about 20.5 knots. Two large pips indicate a carrier and a cruiser. Three definite escorts and probably one more on the strbd bow.
0300 BARB out of the race. We were losing.
0330 Reluctantly abandoned chase. Target two hours out of SASEBO entrance. Fate has been unkind.
17 Nov, 1944.
1354 Heard three explosions, may have been torpedoes (had correct intervals) but sounded more like depth charges.
1357 Made out masts of convoy bearing 016T to 040T.
1413 Made out convoy. A total of 12 large ships with several escorts. 4 AO, 4 AK with 4 goal masts, 2 AP, 1 medium AK, and all have heavy deck loads. Continued to close track.
1454 Sighted aircraft carrier and 4 escorts. Started approach; closed range to 16,000 yds. Watched carrier launch and recover aircraft and then show us both bows as she reversed course and headed away.
1530 Sighted masts of freighters, range about 15,000 yds.
1540 Heard five depth charges (No torpedo explosions). During the next 3 minutes, saw and heard escort drop a total of 24 more to the south of the convoy. Escort must have had a good contact as he stayed with it for about 2 hours. Convoy scattered.
1630 Convoy turned west and formed up. Continued approach. Unable to get in firing position unless they changed course back to the SW.
1703 Convoy, after getting past us on a westerly course at about 8,000 yds range, changed course to SW. We are at the extreme range of Mk 18's but decided to try it anyway after five hours of approach. Calling on the Mk 18's for a full run, and with a prayer, at,
1718 Fired three torpedoes at leading freighter of near column. 100 P track, 10R gyro track, 3,500 yd torpedo run. Followed with three more at 2nd freighter of port column. Same torpedo data. No hits. Last torpedoes were heard running for a full five minutes but apparently slowed enough to go astern or run deep at the end of run.
1725 Last ship in strbd column saw a torpedo go by and turned away.
1731 First of 23 depth charges dropped by an escort astern of convoy.
1845 Surfaced and began chase. Sent contact report on both convoys and carrier.
2133 In position ahead and commenced approach down track. Came left to open track for stern shot. Steadied on course for 90 track, and at,
2207 Fired three torpedoes at leading freighter, 100 track, 2,000 yd run, and one torpedo at second freighter, 95S track, 1,900 yd run. Two hits in first target and it sank in two minutes and one hit in second ship setting it on fire. (Burned for 3.5 hours before finally exploding and sinking at 0132). Near escort dropped at string of nine charges that shook us up, and started shooting in all directions. Then, all Jap hands joined us in celebrating. All ships started firing 3" and 4", 20MM, etc, in all directions, even into the air, and 33 more "blockbuster" depth charges were dropped. Quite a sight. Very little ammunition shot our way. Opened range fast as burning ship was illuminating the entire area. A peculiar intense white flame from bow to stern but not a great deal of smoke. Had a SJ contact, 330T, 9,000 yds, probably PETO that was heading to the north of the convoy.
2309 Sighted flames from a burning ship over the horizon 255T. Looks as if someone has gotten into the other convoy or the carrier. Fifteen minutes later saw a series of large explosions from this fire after which flames went out.
2330 Started tracking an escort that was picking up survivors.
18 Nov, 1944.
0005 Target not following any zig zag plan. Started approach down the track.
0023 Our luck was gone. target sighted us, dropped a depth charge, and opened up with a 20MM gun, straddling us in both range and deflection. How he missed us is a miracle. Dove and fired three down the throat shots. No hits and got two depth charges as he passed by.
0114 Surfaced and commenced chase.
0132 Our burning ship suddenly exploded in a nice burst of fireworks and sank.
0134 Saw a series of explosions (fireworks) to the north (at least one ships blew up) just over the horizon. This was followed by depth charges and much gunfire. Abandoned chase of small AK and headed north after bigger game. Also can draw the dogs off. More depth charges and gunfire. PETO (?) has either attacked the rest of our convoy or has gotten that convoy that China planes had reported as standing out to the north of KOTO.
0136 Saw explosion and flames as from a gasoline tanker. A beautiful sight.
0140 Saw new flames a little to the left as an ammunition ship exploded. This was the most wonderful fireworks display ever seen; exploding shells, etc. Must have gone a mile or more into the sky. Good work by someone on the other convoy.
0146 A goodly number of depth charges to the north. PETO is getting bounced around.
0210 SJ contact, 022 T, 27,000 yds.
0211 More gunfire and depth charges.
0300 Made out two large modern diesel freighters lying to about 4,000 yds apart. They were apparently picking up survivors, escorts were starting and stopping. Can't understand this as this is not a Jap practice, maybe a green outfit, nice targets though. Closed.
0314 Fired three torpedoes at 2,800 yds and started coming left. At this time one escort was 500 yds on the port bow of target passing down his port side. He had a look at our broadside silhouette for at least two minutes, and saw us. Just as we had started swinging left, he came for us, and at, 0315 He opened up on us with everything that he had, starting with a 3" gun and ending with a depth charge, plus a steady stream of 20MM from 3 guns, that a dozen men said that they heard raining on the superstructure and periscope shears. (Later examination revealed they must have been exploding in the water alongside). Dove and rigged for depth charge. Ordered 125 feet in 28 fathoms of water. Diving officer blew negative at 90 feet whereupon we promptly came up. The depth gauge in the After Torpedo Room read "0" and the occupants thereof plainly heard the waves slapping the hull. (See War Story) Final trim revealed that we were 28,000 pounds light. This gave us a few bad moments and probably would have been much worse, had not at,
0317 First of three torpedo hits (just as we get under for the first time), followed by a tremendous explosion that continued to rumble and explode for at least five minutes and gave us a continuous series of shocks. This was accompanied by the most terrible wrenching, grinding, and tearing noises anyone has ever heard. This ship was evidently an ammunition ship and exploded similar to the others that we had witnessed at a distance. The escort apparently did us a favor by forcing us to dive immediately after firing. The explosion must have disabled or sunk both of the close escorts, the one alongside, and the one scheduled to pass over us. It was 25 minutes before sound picked up an escort coming our way from the direction of the other freighter. He got contact (no gradient), and at,
0352 We received a pattern of nine. He stayed with us.
0413 Pattern of ten close, (their new no-click model blockbusters).
0434 Pattern of four fairly close.
0435 One single, closer still. They shake you up in shallow water.
0440 Pattern of four farther away.
0655 Periscope depth. Sighted PC boat about 5,000 yds to the SW searching E-W.
In retrospect we will call this the "First Battle of the Yellow Sea." There were Jap ships burning, blowing up, and sinking over a 50 mile stretch. We have made no attempt to log all of the gunfire sighted or heard, nor all depth charges heard in 18 hours, only those close or intended for us. It is estimated that close to 1,000 depth charges were heard. Apparently the Japs had concentrated at least three convoys along the SW coast of Korea and by providing carrier air coverage, tried to make one big push to get them across to SHANGHAI. Some got through and others turned back but it was a costly 18 hours. If this is future Jap policy, it is suggested that these two areas could accommodate several more submarines with even more devastating results for the Japs.
21 Nov, 1944.
0939 Sighted dead Jap in water, estimated about 48 hours.
1040 Three more Jap bodies and small amount of wreckage. (All bodies in blue trousers and sweaters with life jackets).
1330 Sighted returning B-29's. Six told us hello and gave position.
1500 Sank floating mine with 20MM.
24 Nov, 1944.
2000 Requested rendezvous with SPADEFISH to exchange movie films. Got reply and position. SPADEFISH was 90 miles away! Couldn't believe it. It was here that the future mascot of the SUNFISH "MYRNA" was given to the SUNFISH's crew by the SPADEFISH's crew. She was born at sea while in the patrol area.
29 Nov, 1944.
1930 Received CTG's msg SPADEFISH going home. Feel lonely, out of six boats we are the only one left in area and can feel more lifeguard duty coming up.
30 Nov, 1944.
1353 Two stack small AP (DARIEN Maru class) came into sight rounding the KAN. Range 7,000 yds and he started swinging well out from the KAN.
1403 Target came left, giving zero angle. Only one torpedo aft, nothing for it but to head for the target, and if no zig, fire down the throat.
1410.50 Fired first of three torpedoes, 10L gyro, 70 S track, 850 yd run, target speed 10.5 knts.
1411.30 One hit by last torpedo, just forward of the bridge. Apparently too high of a target speed estimate. Men boiled out from everywhere (all in blue uniform) and they started throwing life rafts, floats, etc, over the side. Target slowly going down by the head. Target heading for the reef. Ship down about 15 degrees by the head.
1416.45 Believe now that target is grounded on the reef. Ship down about 15-20 deg by bow, small list to strbd. Stern surging up and down, bow hard on reef. High stern being swung to left on to the reef by the sea.
1433 After fifteen minutes of observation of target on rocks concluded that transport was hard aground and settling and that she was exposed to the sea. Believe that she would very shortly be beyond salvage.
1450 PCO confirmed transport up on the reef. Transport had settled on the reef, exposed to the seas, and would either break up or be a permanent landmark.
5 Dec, 1944.
0935 Earlier sighted Chinese junk alongside. Evident that they were in distress. Finally made out that they were hungry and had been blown far away from China Banks by the last five day storm (150 miles away). The crew was ready to give them the ship. We gave them a lot of food amid much grateful bowing. When we cast off our lines they set up a wail and made more gestures. It was not until we were clear that I realized their gestures were "drinking" and that they needed water. We circled, while we scouted up a 5 gallon can and (4) gallon jugs and filled them.
1014 Sighted two floating mines and realized that we were in the middle of a floating minefield.
1030 Started coming alongside and held up the water jugs. They shouted and danced so that it did your heart good. Had just thrown a line across when at,
1035 Lookout sighted two engine bomber about 14 miles out flying at us on the port beam. Quickly tossed two water jugs into the junk and got clear. Dove.
1105 Plane out of sight. Started trailing junk while we had dinner. There was no question now of leaving junk. My crew would have mutinied, I am sure, if I hadn't of planned to get the water, and other gear collected, aboard the junk.
1324 Surfaced and received a royal welcome from the junk. Transferred all gear and water.
At this point a very touching incident occurred. Our QM (My Dad) had shown them our flag just before we dived for the plane. We broke out the colors the second time and held them up and they all kneeled and bowed three times and then rose and cheered. We all cheered, and parted company amidst cheers.
6 Dec, 1944.
0800-1053 Sighted ten Jap cadavers in the water. (Army uniforms)
12 Dec, 1944.
Enroute Majuro .
19 Dec, 1944.
0901 Moored alongside USS Gilmore.
10th WAR PATROL, COMMENTS ON:
The tenth war patrol of the SUNFISH, under the command of E.E. SHELBY, was conducted in the Yellow and East China Sea. Despite a through area coverage, the SUNFISH had only three worthwhile contacts during this patrol and attack was prevented by ice floes. On 20 February, off CHOSAN KAN, underwater collision with an ice floe bent both periscopes preventing their further usage and necessitating return to base. The Commander Submarine Force, Pacific Fleet, sympathizes with the SUNFISH for this unfortunate casualty and the lack of opportunity to inflict damage upon the enemy. (J.H. BROWN)
It is unfortunate that periscope damage, suffered during an aggressive attempt to close to attack position on an enemy ship, terminated her patrol early and deprived the SUNFISH of part of her scheduled opportunity to inflict damage upon the enemy. (L.S. Parks)
Commander Submarine Division 202 regrets with the Commanding Officer, officers, and men of the SUNFISH the periscope casualty that denied them the opportunity of adding to their already large bag of enemy shipping. He congratulates them on the completion of an arduous patrol. (Rob Roy McGregor) (He later became the technical advisor for the film, "Run Silent, Run Deep.")
15 Jan, 1945.
1002 Underway and stood out of Majuro, enroute Saipan, in company with USS GATO.
22 Jan, 1945.
1240 Moored alongside USS FULTON, Saipan.
29 Jan, 1945.
0900 Departed Saipan for patrol area.
20 Feb, 1945.
0635 Submerged for patrol.
1015 Sighted masts of target.
1020 A single stack 1,000-1,500 ton freighter came into view hugging the coast, just before rounding the tip of CHOSAN KAN. This put the ice-floe between us and the target about 6,000 yds away. Started out around northeast end of floe to get to the north side.
1100 (Periscope): - Smoke bearing 024T, on other side if ice-floe. We would have to get on the other side of the floe to attack in open water, but would not have time to go around the floe. Planned to close the target and when necessary to continue past the floe, go deep, and pass under floe, which appeared to be about 300 yds wide.
1210 #2 periscope had been run down about 10 feet (about 500 yds away from floe), after an observation, when it struck the floe. Lowered it immediately. Concluded it had struck an unobserved piece of the ice-floe. Came right and tried to raise #1 scope. #1 scope hit while being raised and lowered it immediately, jamming on the way down. Came to SW course and ran standard speed for several minutes, then tried #1 scope again. Got it up but with heavy strain on motor. About ¼ of the field was visible and the field cocked at an angle. Watched target stand down towards ice field.
1247 The ice-floe completely blocked the entrance between CHOSAN KAN and HAKUREI TO to the south. The target could not enter, reversed course, and stood back inside the reef to the north of CHOSAN KAN.
1325 Commenced standing out to the open sea.
1817 Surfaced eighteen miles west of CHOSAN KAN and inspected periscopes. #1 bent about 3 degrees aft and slightly to one side, barely usable. #2 periscope bent about 20 degrees at a point two feet from the tip, making it unusable. (John Baguley later said to me, "that it was strange to surface and wonder if anything was up there.")
27 Feb, 1945.
0600 Moored APRA HARBOR, Guam.
11th WAR PATROL, COMMENTS ON:
The eleventh war patrol of the SUNFISH, under command of Lt Cdmr J.W. REED, was conducted in the areas off of the east coast of HONSHU and the southern coast of HOKKAIDO. The SUNFISH coordinated her patrol with the PARCHE. The Commander Submarine Force, Pacific Fleet, congratulates the commanding officer, officers, and crew of the SUNFISH for this aggressive and successful patrol added to her brilliant record. During the past ten patrols, she is credited with having sunk nineteen enemy ships totaling 147,386 tons and damaging five enemy ships totaling 44,104 tons. (MERRILL COMSTOCK)

1730 Underway for 11th war patrol. In company of TRUTTA and PARCHE. Enroute area.
1 Apr, 1945.
1245 Sighted PUFFER and PETO on opposite course. Exchanged recognition signals. Headed to area THREE.
9 Apr, 1945.
1309 Heard definite torpedo explosion to south of us followed by depth charging. Must be PARCHE at work on somebody.
1409 Sighted funnel and mast of ship bearing 199T, range 17,000 yds, zero angle on the bow. Target appears to be a medium naval auxiliary with "bed spring" type radar forward of funnel. Commenced tracking, speed 14.5 knts.
1445 Target zigged towards giving us a 10 deg strbd angle on the bow. Came left for a stern shot.
1447 Target zigging left presenting us with about a 150 deg strbd angle on the bow.
1448 Realized it was now or never; accepted unfavorable setup and commenced firing four torpedoes aft.
1450.24 Torpedo explosion timed for first torpedo fired. Took a look at target and saw huge geyser of water at the stern of target.
1454 Target began kicking over depth charges and firing stern gun. Sound heard pinging from direction of the target. Target fishtailing, disappearing into YAMADA KO.
1508 Small fast boat heading towards us, probably PT boat. Came left and headed out to clear 100 fathom curve.
14 Apr, 1945.
0831 Sighted medium freighter, similar to BENGAL MARU, page 240, ONI 208-J, bearing 291T, range 12,000 yds, coming down from the north-west hugging the beach. Commenced tracking.
1014 Fired three torpedoes forward for a 90 strbd track, 30L gyro, and a 3,000 yd run.
1019 One torpedo exploded on the beach. All torpedoes missed target. Target unaware that he had been fired upon. About a minute after firing, target swung left to swing around ESAN SAKI.
1158 Sighted float plane.
1820 Surfaced. Sighted patrol boat at 8,000 yds, put it behind us and opened out. ESAN SAKI looks like a good hunting ground. Plan to visit it again soon.
16 Apr, 1945.
0256 SJ radar contact, 290T, range 9,000 yds.
0615 Sighted HASHADATE type patrol boat emerging from fog bank bearing 037T, range 4 miles. Went to battle station; commenced tracking.
0850 Sound reported screws ahead. Sighted 5 merchantmen coming out of YAMADA KO with 3 escorts. Came right to close track. Sighted small float plane circling over convoy.
0855 Sound reports pinging on port quarter. This is a new one! Quick look shows another patrol boat 3,000 yds on our port quarter.
0908 Coming in for a bow shot on largest AK when leading escort, (same HASHADATE that we had sighted earlier on anti-sub sweep) zigged across our bow presenting a beautiful shot. Just couldn't let him go by. Fired three torpedoes on a 90 strbd track, range 2,500 yds, gyros 3L.
0912 Commenced swinging left for a stern shot.
0913 Heard two loud torpedo hits, 10 secs apart, followed by loud breaking up noises, which could be heard throughout the hull. We took so much water forward that the periscope dunked. Could not see results on AK.
0914 Twelve close depth charges that knocked pit log off of the bulkhead, broke several light bulbs, and caused the forward torpedo room hatch to show "open". Loud screws all around. Rigged for silent running and eased below a 2 degree negative gradient and started working out to deep water. We were worked over by three escorts that knew their jobs. Counted a total of 50 depth charges.
1855 All clear on sound and SJ radar. Surfaced; completing a grueling 16 hour dive!
17 Apr, 1945.
1835 Heard two depth charges. Japs have a habit of dropping a pattern of charges just about sunset in this area.
18 Apr, 1945.
2247 SJ contact, two pips bearing 060T, range 37,000 yards!! Commenced tracking on 3 engines, finishing charge on one engine.
19 Apr, 1945.
0000 Tracking earlier radar contacts. Crew at battle stations.
0035 Changed course to 050T, coming in for the attack.
0039 Targets are overlapping. 60 deg port track, gyros 13R, and torpedo run to leading target is 1,900 yds. Commenced firing 6 tubes forward using radar bearings. Each torpedo plainly visible as it left the tube and steadied up.
0041 Swinging right. Heard first of two torpedo explosions. Saw huge column of water but unable to see the ships. Sighted red rocket from target.
0046 Heard explosion from direction of target. Radar pip on leading target growing smaller. Tracking has it dead in the water.
0053 Heard another explosion from the target. Sound hears crackling noises from the target.
0057 Commenced tracking on remaining pip. Working ahead of target. Beach is 4 miles away.
0153 Commenced firing of four torpedoes aft, 90 port track, gyros 15R, run 2,300 yds, using radar bearings.
0156 Saw, heard, and felt one torpedo explosion. Still can't see target.
0214 Fired one torpedo for a 70 port track, gyro 1L, range 1,000 yds, using TBT bearings of flashes of light that checked with radar bearings. Torpedo missed. Possible erratic torpedo performance as this torpedo had a large air leak. Commenced opening out towards deep water.
0240 Radar reports pip of target collapsed and disappeared. Target originally picked up at 37,000 yds. Now, nothing on radar but land echoes.
20 April, 1945.
0007 Received orders from COMSUBPAC to head for Pearl.
Final Note: One this patrol, one case of ACUTE APPENDICITIS responded to treatment with morphine, strict diet, and bed rest. Also, one tooth was extracted while on patrol. The performance of the officers and men under fire was in keeping with the highest traditions of the service and left nothing to be desired.
