At 2:30 p.m., Brigadier General Joshua 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 corps. Under heavy fire, Chamberlain's brigade, along with Colonel (Brevet Brigadier General) Edgar M. Gregory's brigade, charged Hunton's brigade and drove Hunton's troops back to the White Oak Road Line, which allowed Chamberlain's and Gregory's men across White Oak Road. The remainder of the Confederate force then had to withdraw to avoid being outflanked and overwhelmed. Warren's corps ended the battle again across a section of White Oak Road between the end of the main Confederate line and Pickett's force at Five Forks, cutting the direct route of communications between Anderson's (Johnson's) and Pickett's forces. Union casualties (killed, wounded, missing presumably mostly captured) were 1,407 from the V Corps and 461 from the II Corps and Confederate casualties have been estimated at about 800.
