On March 31, 1865 General Pickett, commander of the Confederate forces at Five Forks had launched an attack on Sheridan’s troopers driving them south to just north of Dinwiddie Court House. However, his left flank being threatened by troops of the V Corps arriving to reinforce Sheridan, Pickett retreated to Five Forks. Sheridan followed the retreating Pickett, and launched an attack on the Confederate breastworks at 1:00 PM on April 1, with two divisions of dismounted Union cavalry, armed with Sharps repeating rifles. This intense fire pinned down the Confederates while the infantry of the V Corps massed to attack the Confederate left. At 4:15 the attack went in , overcoming a stubborn Confederate defense. Sheridan removed General Warren from command of the V Corps on the grounds of being dilatory in arranging the attack of the V Corps, a decision which was ruled unfounded by an Army court of inquiry in 1883. Confederate casualties were almost 3,000 many of them prisoners, and Union casualties were 830. The Confederate right had now been turned, and largely obliterated, and the Southside Railroad lay exposed to the Union. Richmond and Petersburg could no longer be held.
