Gravelly Run. Adjacent to the V Corps in the line, the II Corps under Major General Andrew A. Humphreys sent two of Brigadier General Nelson Miles's brigades forward and they initially surprised and after a sharp fight drove back Wise's brigade on the left of the Confederate line, taking about 100 prisoners. Humphreys also ordered three diversionary demonstrations along the adjacent line to prevent the Confederates from reinforcing Johnson. Because no reinforcements were available, Johnson pulled his tired men back to the line of fortifications south of White Oak Road that Ayres's men had set up the night before. Miles saw through his field glasses that the Confederate rifle pits west of Boydton Plank Road were unoccupied but because the 5th New Hampshire Regiment's attack was in the wrong place on the line, the Confederates were able to reoccupy the empty trenches. Griffin's V Corps brigade and Wainwright's artillery stabilized the Union line by 1:00 p.m. Warren and Griffin then approached Brigadier General Joshua Chamberlain, wounded only two days earlier at the Battle of Lewis's Farm, with the question: "General Chamberlain, will you save the honor of the Fifth Corps?" Despite the pain from his wounds suffered at Lewis's Farm, Chamberlain agreed to the assignment. At 2:30 p.m., 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 units. From Johnson's new position in rifle pits south of White Oak Road, which had been constructed by Ayres's men, the Confederates hit Chamberlain's men with a heavy fire as they emerged from the nearby woods. Warren ordered Chamberlain to hold his position but Chamberlain suggested to Griffin that they would be better off attacking the Confederates than remaining under fire and being picked off. Griffin approved the proposal and Chamberlain's brigade, along with the brigade commanded by Colonel (Brevet Brigadier General) Edgar M. Gregory, charged Hunton's brigade and drove them back to the White Oak Road Line. Then Chamberlain's and Gregory's men crossed White Oak Road. The remainder of the Confederate force then had to withdraw to prevent being outflanked and overwhelmed. Warren's men pursued across White Oak Road west of Claiborne Road but after a personal reconnaissance where Warren and a large party of scouts came under fire, Warren concluded that an immediate attack on the Confederate fortifications would gain nothing. Warren's corps ended the battle having gained
