Five Forks. Ayres's division, which had not engaged in the combat as Chamberlain and Gregory pushed the Confederates back, 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 and nearly completely cut communication between them. Warren connected his forces before receiving a message from Meade's chief of staff, Brigadier General and Brevet Major General Alexander S. Webb, to do just that. Webb stated that it was believed that Sheridan was advancing but in fact they were being pushed back by Pickett's force at the Battle of Dinwiddie Court House. Casualties Historian Chris M. Calkins gives the Union casualties (killed, wounded, missing – presumably mostly captured) as 1,407 from the Fifth Corps and 461 from the Second Corps and Confederate casualties as about 800. The Civil War Trust online gives similar casualty figures in round numbers as 1,800 of the Union force and 800 of the Confederate force. David W. Lowe in Frances H. Kennedy, ed., The Civil War Battlefield Guide gives the casualties as Union 1,781 and Confederate as 900–1,235. Aftermath As a result of the battle, the Confederates had lost control of the White Oak Road, were trapped in their works and had lost the direct line of communication to Pickett's force. The Confederates had taken losses they could not afford and suffered a blow to their morale. While Warren's V Corps led by Griffin's division, with help from Miles's division of Humphrey's II Corps, turned the Battle of White Oak Road into a Union victory, Sheridan had to save his imperiled troopers who were hard pressed as the Battle of Dinwiddie Court House ended for the day. The Confederates won the day on March 31 at Dinwiddie Court House by pushing the Union cavalry into a tight position. But when Warren heard the sound of the distant battle receding toward Dinwiddie Court House, he sent Brigadier General Joseph J. Bartlett's brigade of Griffin's division to reinforce Sheridan and attack Pickett's force on its flank. Since it was dark when Bartlett's men reach Gravelly Run, they did not try to cross but engaged the Confederates on the other side with sniper fire. About 6:00 p.m., Meade learned that Pickett in fact was pushing Sheridan back to Dinwiddie Court House. Meade ordered Warren to send a force to Sheridan down the Boydton Plank Road. Warren
