junction of the Quaker Road and Boydton Plank Road near the end of the Confederate White Oak Road Line. Late in the afternoon of March 29, 1865, Sheridan's cavalry occupied Dinwiddie Court House on the Boydton Plank Road without opposition. The Union forces had cut the Boydton Plank Road in two places and were close to the Confederate line and in a strong position to move a large force against both the Confederate right flank and the crucial road junction at Five Forks in Dinwiddie County to which Lee was just sending Pickett's mobile force defenders. The Union Army was nearly in position to attack the two remaining Confederate railroad connections with Petersburg and Richmond, if they could take Five Forks. Encouraged by the Confederate failure to press their attack at Lewis's Farm and their withdrawal to their White Oak Road Line, Grant decided to expand Sheridan's mission to a major offensive rather than just a possible battle or a railroad raid and forced extension of the Confederate line.

Lee ordered Major General Bushrod Johnson to have his remaining brigades under Brigadier General Henry A. Wise and Colonel Martin L. Stansel in lieu of the ill Young Marshall Moody, reinforced by the brigades of Brigadier Generals Samuel McGowan and Eppa Hunton, attack the exposed Union line. Stansel's, McGowan's and Hunton's brigades attacked both most of Ayres's division and all of Crawford's division which quickly had joined the fight as it erupted. In this initial encounter, two Union divisions of over 5,000 men were thrown back across Gravelly Run by three Confederate brigades.

Humphreys conducted diversionary demonstrations and sent two of Brigadier General (Brevet Major General) Nelson Miles's brigades from his II Corps forward. They initially surprised and, after a sharp fight, drove back Wise's brigade on the
