Fortress Monroe lies at the apex of a wedge-shaped peninsula formed by the York and James Rivers, which converge as they flow toward the coast. April 4th, McClellan started on his march up this peninsula. A line of Confederate fortifications, twelve miles long, stretched across it, from Yorktown to the James, defended by 10,000 men. Yorktown must be taken to turn this line. A month was wasted in laborious siege preparations, for early in May, just before an overwhelming cannonade was to begin, the southern army evacuated the place and retreated toward Richmond.

McClellan hurried after it. A desultory battle was fought all day on the 5th, near Williamsburg, the enemy withdrawing at night. McClellan now moved slowly up the peninsula, the last of May finding his army within ten miles of Richmond, encamped on both sides of the Chickahominy. By this time nearly 70,000 troops had gathered for the defence of the Confederate capital.

May 31st, the Confederate General Joseph E. Johnston fell upon the part of McClellan’s army south of the river, at Fair Oaks, and in a bloody battle drove it back a mile. McClellan sent re-enforcements across the river, and the retreat was stayed. The lost ground was regained next day, and the enemy driven into Richmond. Johnston having been wounded, General Robert E. Lee was now placed in command of the Army of Virginia, destined to lay it down only at the collapse of the Confederate government.

McClellan waited three weeks for better weather. He also expected McDowell’s corps of 45,000, which had been kept near Fredericksburg to defend Washington, but was under orders at the proper time to cooperate with McClellan by moving against Richmond from the north. But Stonewall Jackson came raiding down the Shenandoah Valley, hustling General Banks before him. Washington was alarmed, and McDowell had to be retained.

Lee boldly took the offensive, and the “Seven Days’ Fight” began. June 26th he attacked McClellan’s extreme right under Porter, on the north side of the Chickahominy. He was repulsed, but Porter fell back farther down the river to Gaines’s Mill, there fought all the next day against great odds, and was saved from total rout toward night only by the arrival of re-enforcements.
