possession of a part of White Oak Road to the west of the Confederate right flank, which was between the end of the Confederate line and Pickett's force at Five Forks. Ayres's division stopped just short of White Oak Road, facing west toward Five Forks. This cut the direct communication route between Anderson's (Johnson's) and Pickett's forces. Union casualties (killed, wounded, missing – presumably mostly captured) were 1,407 from the Fifth Corps and 461 from the Second Corps and Confederate casualties have been estimated at about 800. Dinwiddie Court House (March 31) About 5:00 p.m. on March 29, 1865, Major General Philip Sheridan led two of his three divisions of Union cavalry, totalling about 9,000 men counting the trailing division, unopposed into Dinwiddie Court House, Virginia, about west of the end of the Confederate lines and about south of the important road junction at Five Forks, Virginia. Sheridan planned to occupy Five Forks the next day. That night, under orders from General Robert E. Lee, Confederate Major General Fitzhugh Lee led his cavalry division from Sutherland Station to Five Forks to defend against an anticipated Union drive to the South Side Railroad in order to cut use of that important final Confederate railroad supply line to Petersburg. Fitzhugh Lee arrived at Five Forks with his division early on the morning of March 30 and headed toward Dinwiddie Court House. On March 30, 1865, in driving rain, Sheridan sent Union cavalry patrols from Brigadier General Thomas Devin's division to seize Five Forks, key junction for reaching the South Side Railroad. Devin's force unexpectedly found and skirmished with units of Fitzhugh Lee's cavalry division. A patrol of the 6th United States Cavalry Regiment under Major Robert M. Morris lost 3 officers and 20 men in the encounter with Fitzhugh Lee's troopers. Confederates casualties included Brigadier General William H. F. Payne who was wounded. That night Confederate Major General George Pickett reached Five Forks with about 6,000 infantrymen in five brigades (under Brigadier Generals William R. Terry, Montgomery Dent Corse, George H. Steuart, Matt Whitaker Ransom and William Henry Wallace) and took overall command of the operation as ordered by General Robert E. Lee. General Lee was concerned that detected Union Army movements were aimed at Five Forks and the South Side Railroad. The cavalry divisions of Major Generals Thomas L. Rosser and W.H.F. "Rooney" Lee arrived at Five Forks late that night.
