Brigadier-General J. H. Martindale (seated) and his staff, July 1, 1862. Fitz John Porter's Fifth Corps and Couch's division, Fourth Corps, bore the brunt of battle at Malvern Hill where the troops of McClellan withstood the terrific attacks of Lee's combined and superior forces. Fiery "Prince John" Magruder hurled column after column against the left of the Federal line, but every charge was met and repulsed through the long hot summer afternoon. Martindale's brigade of the Fifth Corps was early called into action, and its commander, by the gallant fighting of his troops, won the brevet of Major-General.

Glad indeed were the men of the Army of the Potomac as they emerged from their perilous march across White Oak Swamp to hear the firing of the gunboats on the James. It told them the Confederates had not yet preëmpted the occupation of Malvern Hill, which General Fitz John Porter's Corps was holding. Before the battle opened McClellan went aboard the _Galena_ to consult with Commodore John Rodgers about a suitable base on the James. The gunboats of the fleet supported the flanks of the army during the battle and are said to have silenced one of the Confederate batteries.

In about a month, McClellan had changed the position of his army twice, shifting his base from the Pamunkey to the James. The position he held on Malvern Hill was abandoned after the victory of July 1, 1862, and the army marched to a new base farther down the James, where the heavy losses of men and supplies during the Seven Days could be made up without danger and delay. Harrison's Landing was the point selected, and here the army recuperated, wondering what would be the next step. Below we see the historic mansion which did service as General Porter's headquarters, one of McClellan's most efficient commanders. For his services during the Seven Days he was made Major-General of Volunteers. McClellan was his lifelong friend.
