During the early hours of the morning the Fourth United States Infantry relieved the Twentieth Massachusetts Regiment from their entrenched position along William Street. The exhausted Twentieth withdrew to the city of Fredericksburg.
In light of the slaughter of the previous day General Edwin "Bull" Sumner convinced General Ambrose Burnside to abandon additional assaults by all three Grand Divisions.
