392. The Peninsular Campaign, 1862.--By the end of May McClellan had gained a position within ten miles of Richmond. Meantime, Jackson fought so vigorously in the Shenandoah Valley that the Washington government refused to send more men to McClellan, although Johnston had gone with his army to the defense of Richmond. On May 31 the Army of the Potomac and the Army of Northern Virginia fought a hard battle at Fair Oaks. Johnston was wounded, and Lee took the chief command. He summoned Jackson from the Valley and attacked McClellan day after day, June 26 to July 2, 1862. These terrible battles of the Seven Days forced McClellan to change his base to the James, where he would be near the fleet. At Malvern Hill Lee and Jackson once more attacked him and were beaten off with fearful loss. [Sidenote: Lee's plan of campaign.] [Sidenote: Second battle of Bull Run, August, 1862.] 393. Second Bull Run Campaign.--The Army of the Potomac was still uncomfortably near Richmond. It occurred to Lee that if he should strike a hard blow at the army in front of Washington, Lincoln would recall McClellan. Suddenly, without any warning, Jackson appeared at Manassas Junction (p. 317). McClellan was at once ordered to transport his army by water to the Potomac, and place it under the orders of General John Pope, commanding the forces in front of Washington. McClellan did as he was ordered. But Lee moved faster than he could move. Before the Army of the Potomac was thoroughly in Pope's grasp, Lee attacked the Union forces near Bull Run. He defeated them, drove them off the field and back into the forts defending Washington (August, 1862).

But he found more resistance than he had looked for. McClellan was again given chief command. Gathering his forces firmly together, he kept between Lee and Washington, and threatened Lee's communications with Virginia. The Confederates drew back. McClellan found them strongly posted near the Antietam and attacked them. The Union soldiers fought splendidly. But military writers say that McClellan's attacks were not well planned. At all events, the Army of the Potomac lost more than twelve thousand men to less than ten thousand on the Confederate side, and Lee made good his retreat to Virginia. McClellan was now removed from command, and Ambrose E. Burnside became chief of the Army of the Potomac.
