Patrol Narrative:

 

September 13, 1942:

 

15:20   Entered assigned patrol area without being spotted by the enemy.  Began patrol by following zigzag pattern over known shipping lanes.

 

23:40   Received Ultra report of possible convoy heading 180 at approximately 21-28N  120-00E.   Plotted intercept course and ordered all ahead full.

 

September 14, 1942:

 

06:00   Received a new Ultra communication detailing a closer convoy.  Adjusted course to intercept.

 

09:05  Lookouts spotted a three ship convoy, dead ahead moving away.  We accelerated to flank speed and performed an end around maneuver to get in front of them.

 

10:31  Achieved ideal attack position.  Dove to periscope scope depth when the enemy reached 8,000 yards. 

 

10:40  Accelerated to flank speed to position myself just off the convoy’s starboard bow.

 

10:46  Took periscope observations to update the TDC solution

 

11:05  Convoy now at 1,000 yards.  Commenced attack.

 

Fired two Mk 14’s at middle ship.  The first prematurely detonated.  The second hit and cracked the ship in two.

 

Adjusted target and fired two fish at the first ship in the convoy.  Without waiting for the results, I ordered right full rudder and swung the Sargo around for a stern shot on the last ship in the convoy. 

 

Just before firing on the last ship, sonar reported two hits on the first ship.  Amazingly, she wasn’t destroyed.

 

With a solid TDC solution on the last ship, I fired two fish from the stern tubes.  Both hit and sunk the merchant.

 

11:12  I swung the Sargo again to bring the stern tubes to bear on the first ship in the convoy.  She was making about 2 knots even after taking two hits from my forward tubes.  I fired a single Mk 14.  Torpedo tore a massive hole in her side.  The ship sunk beneath the waves in minutes.

 

11:14 Surfaced the boat to continue my search along the known shipping lanes.  Ran at 2/3 speed to recharge the batteries to full.  Also commenced full reload on all tubes.

 

13:06  Lookouts reported a ship at 8,500 yards heading right at us.  We dove to periscope depth and maneuvered to ship’s port bow for the attack.

 

13:13  Setup was text book -- single ship, no zigzagging and no escorts.  We fired 2 fish at 1,300 yards.  The first ran erratically off to port.  The second one hit, but was a dud.  The air flask was seen to detonate.

 

Closed the distance to 800 yards and fired the remaining two fish from the bow tubes.  Both were duds.

 

13:21  Ordered right full rudder to swing the Sargo about for a stern shot.  The Jap merchant was now more than aware of our presence and made a run for it.

 

13:23  Fired two fish at 1,100 yards.  Both were duds.  Fired remaining two torpedoes.  Again both were duds.

 

13:24  Attempted to follow the target while submerged to give the torpedo crews time to reload.    Had to increase to flank speed to keep the target within range. 

 

13:36  Tube one was reloaded.  Fired single fish at 1,600 yards to slow the target.  Shot missed.  The target was able to increase speed.  She might have brought a new boiler on line.

 

14:11 Target was almost out of sight to the northeast.  Surfaced the boat to try and get around her.  Seas were extremely rough.  Best speed we can make is 12 knots.  Attempting to plot an end around run

 

15:51  A check with the navigator shows that the target has exited our assigned patrol area.  After almost an hour and a half, we have been unable to catch up the target.  I ordered us about to return to our assignment.  Radioed to ComSubSoWesPac  the course and speed of the target.  Hopefully someone else can get her.

 

September 15, 1942:

 

06:13 Lookouts spotted a destroyer coming our way.  At 6,000 yards we dove to periscope depth and change course in order to get out of her way.

 

Periscope observation revealed that she was part of a 5 ship convoy.  The convoy consisted of 4 destroyers and one cruiser.  As per the ROE, I avoided all four destroyers. 

 

I considered taking on the cruiser, but with the failures of 8 torpedoes in a row, I’m not at all confident about taking on a warship.

 

07:10  Periscope observation revealed clear seas above.  We surfaced.

 

07:31  SD contact with aircraft at 17,000 yards, closing fast.  We were unable to see the aircraft due to low cloud cover.  Dove to periscope depth and changed course to be safe.

 

08:07  Came up to radar depth and could make  no SD contact.  Sonar immediately notified us of low speed screws bearing 336. 

 

08:12 Order flank speed to get reach intercept point for this new 3 ship convoy

 

This one was unescorted and a prime target for us to use up the remaining 4 torpedoes.

 

08:15  I misjudged the convoy speed.  They were much closer than anticipated.  Fired a single Mk 14 from bow tube at 1,300 yards.  Hit the lead ship and sunk her.

 

Fired single fish from the bow at the second ship in the convoy.  Again hit and destroyed her.

 

Fired last bow torpedo at the third and final ship in the convoy.  After leaving the tube, the torpedo ran erratically off to starboard.

 

 

08:19  Order right full rudder to bring the stern around to shoot my last fish. 

 

08:26  Setup was perfect.  Target was bearing 181.  Fired last torpedo.  It hit her amidships and damaged her.   She continued to make good speed.  Being out of torpedoes, I surfaced the boat and commenced to finish her off with the deck gun.  Due to the rough seas and inexperience of my gun crew, it took 28 rounds to sink the target.

 

08:47  With no more torpedoes, I decided to return to port.

 

September 26, 1942

 

07:10  Arrived in port and commenced re-supply and refit.
