while warren's v corps led by griffin's division, with help from miles's division of humphrey's ii corps, turned the battle of white oak road into a union victory, sheridan had to save his imperiled troopers who were hard pressed as the battle of dinwiddie court house ended for the day. the confederates won the day on march 31 at dinwiddie court house by pushing the union cavalry into a tight position. but when warren heard the sound of the distant battle receding toward dinwiddie court house, he sent brigadier general joseph j. bartlett's brigade of griffin's division to reinforce sheridan and attack pickett's force on its flank. since it was dark when bartlett's men reach gravelly run, they did not try to cross but engaged the confederates on the other side with sniper fire.
