In the early morning of March 29, 1865, two corps of the Union Army of the Potomac, the V Corps under Major General Gouverneur K. Warren and the II Corps under Major General Andrew A. Humphreys, moved to the south and west of the Union line south of Petersburg toward the end of the Confederate line. The Confederate defenses were manned by the Fourth Corps of the Army of Northern Virginia under the command of Lieutenant General Richard H. Anderson. The corps only included the division of Major General Bushrod Johnson.
