brigade moved to the southwest side of Hatcher's Run, having already just moved to Burgess Mill. Brigadier General Eppa Hunton's brigade of Pickett's division joined Anderson and Bushrod Johnson along the White Oak Road Line near the junction with the Claiborne Road. Major General Bryan Grimes's division reinforced Brigadier General Edward L. Thomas's brigade which had to fill in part of the line formerly occupied by Scales's brigade. Confederate First Corps Commander, Lieutenant General A. P. Hill, returned to duty from sick leave on March 31. Union actions The incessant rain severely hampered operations and the Union army's mobile force's ability to keep supplies moving to their new positions. A large number of Warren's V Corps soldiers had to help the teamsters move wagons and horses through the mud and even to corduroy roads. Gravelly Run was swollen to three times its usual size and bridges and pontoons on Hatcher's Run were swept away. Skirmishers from the V Corps kept the Confederates mostly in their White Oak Road Line between the Boydton Plank Road and Claiborne Road on March 30. Despite incomplete information and somewhat vague and conflicting orders from Meade and Grant, on Grant's order, Warren pushed the Union V Corps forward to strengthen his hold on a part of the Boydton Plank Road. The V Corps entrenched a line to cover that road from its intersection with Dabney Mill Road south to Gravelly Run. In the afternoon, Warren saw Griffin's men take over Confederate outposts but he also saw that any attempted movement further up the Boydton Plank Road was covered by Confederate artillery and fortifications. Meanwhile, Humphrey's II Corps closed the gap between the V Corps and the XXIV Corps. The XXIV Corps captured a large part of the Confederate picket line in their front. Humphrey's corps also moved as close to the Confederate line as possible without starting a general engagement and entrenched at the forward positions. Union casualties for the March 30 actions at the White Oak Road Line were 1 killed, 7 wounded and 15 missing; the number of Confederate casualties is unknown. During the night of March 30, Grant advised Meade not to have the VI Corps and IX Corps make a general attack along the line on March 31 as earlier planned, but to stand ready to take advantage of any sign that the Confederates had weakened their line. Grant also noted
