 The attack was yet another failure, adding to the high toll of casualties as the Union corps was held up by the fire of a single Confederate division.Not only was the V Corps unable to take its objective, it had also failed to draw Confederate troops from elsewhere in the line, as Grant had intended.Both Meade and Grant were upset with Warren's performance and Grant authorized Meade to relieve Warren, replacing him with Meade's chief of staff, Maj. Gen. Andrew A. Humphreys.
