Following the Confederate withdrawal from their Yorktown position, Maj. Gen. George B. McClellan was not prepared to mount an immediate pursuit with his entire force from the siege lines he had occupied for nearly a month. Initially, he was able to send forward only a portion of his army, led by the Third Corps of Samuel P. Heitzelman, to follow Gen. Joseph E. Johnston's Confederates. Heitzelman's divisions, led by Brig. Gens. Joseph Hooker and Phil Kearny, made contact with Johnston's army four miles sout…READ MORE

Lee also sought to take the war out of the ravaged Virginia farmland and gather supplies for his Army of Northern Virginia. Using the Shenandoah Valley as cover for his army, Lee was pursued first by Union Maj. Gen. Joseph Ho…READ MORE
