and to support Sheridan's cavalry. Warren's corps moved out at 3:00 a.m. over the Vaughan Road toward Dinwiddie Court House. Warren's orders were subsequently modified to make a movement over the Quaker Road toward the Confederate defenses. Grant ordered Humphrey's II Corps to march at 9:00 a.m. to positions from the Quaker Road-Vaughan Road intersection to Hatcher's Run. Warren was to move along the Boydton Plank Road to cut that key Confederate communication line. Both corps were ordered to keep the Confederates in their trenches while the Union advance proceeded. Anticipating the Union moves, Lee ordered Major Generals Fitzhugh Lee's, W.H.F. "Rooney" Lee's and Thomas L. Rosser's cavalry divisions to defend the western end of the line, including the important road junction of Five Forks in Dinwiddie County. Fitzhugh Lee started that day, leaving Longstreet with only Brigadier General Martin Gary's cavalry brigade for scouting duties. Lee also prepared for Major General George Pickett to move his men to join the cavalry and take command. Five Forks was along the shortest route to the South Side Railroad. Lee ordered the movement of the infantry the next morning when he learned that Union forces were headed toward Dinwiddie Court House. With his trenches ending at the Claiborne Road-White Oak intersection, Lee had to send Pickett past the end of the Confederate line of defenses in order to defend Five Forks.
