left of the Confederate line, taking about 100 prisoners. At 2:30 p.m., Brigadier General Joshua Chamberlain's men forded the cold, swollen Gravelly Run, followed by the rest of Griffin's division and then the rest of Warren's reorganized corps. Under heavy fire, Chamberlain's brigade, along with Colonel (Brevet Brigadier General) Edgar M. Gregory's brigade, charged Hunton's brigade and drove Hunton's troops back to the White Oak Road Line, which allowed Chamberlain's and Gregory's men across White Oak Road. The remainder of the Confederate force then had to withdraw to avoid being outflanked and overwhelmed. Warren's corps ended the battle again across a section of White Oak Road between the end of the main Confederate line and Pickett's force at Five Forks, cutting the direct route of communications between Anderson's (Johnson's) and Pickett's forces. Union casualties (killed, wounded, missing presumably mostly captured) were 1,407 from the V Corps and 461 from the II Corps and Confederate casualties have been estimated at about 800. Battle of Dinwiddie Court House About 5:00 p.m. on March 29, 1865, Major General Philip Sheridan led two of his three divisions of Union cavalry, totaling 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. 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's Station to Five Forks to defend against an anticipated Union drive to the South Side Railroad which could sever 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. Devin's force unexpectedly found and skirmished with units of Fitzhugh Lee's cavalry division. 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 Corse, George H. Steuart, Matt Ransom and William Henry Wallace) and took overall command of the operation as ordered by General Lee. The cavalry divisions of Major Generals Thomas L. Rosser and W.H.F. "Rooney" Lee arrived at Five Forks late
