The battles took place near Richmond, Va. Confederate General Robert E. Lee drove the invading Union Army of the Pototmac, commanded by General George B. McClellan, away from Richmond and into a retreat down the Virginia Peninsula. The Seven Days Battles ended the Peninsula Campaign. The Army of the Potomac encamped around Berkeley Plantation, birthplace of William Henry Harrison, remaining in its position near the safety of the James River, protected by fire from Union gunboats, but suffering from heat, humidity, and disease. In August, they were withdrawn by order of President Lincoln to reinforce the Army of Virginia in the Second Battle of Bull Run. The casualties on both sides were tremendous. Lee's Army of Northern Virginia suffered about 20,000 casualties (3,286 killed, 15,909 wounded, 946 captured or missing) out of a total of over 90,000 men during the Seven Days. McClellan reported about 16,000 casualties, (1,734 killed, 8,062 wounded, 6,053 captured or missing) out of a total of 105,445 soldiers. Despite their victory, many Confederates were stunned by the losses.
