Up to this point, the entire corps had never fought a major engagement as a whole, only pieces of it participating in the battles on the Peninsula and Antietam. Their chance finally came when Maj. Gen. Joseph Hooker took the Army of the Potomac to Chancellorsville he left the VI Corps in front of Fredericksburg, which was still held by a strong force of the enemy. Maj. Gen. John Sedgwick, who had succeeded to the corps command, ordered an assault on Marye's Heights, and that strong position that had defied the assaults of the previous battle, was now carried by the VI Corps at the point of the bayonet. The divisions of Newton and Howe were the ones engaged together with Col Hiram Burnham's Light Division. Brooks's (1st) Division was engaged later in the day, at Salem Church. The corps lost in this battle 4,589 (485 killed, 2,619 wounded, 1,485 missing). The missing ones were, for the most part, lost in the action at Salem Church. On the day before this battle, the corps returns showed a strength of 23,730, "present for duty", of whom less than 20,000 were present in action. The Light Division was broken up after the battle, its regiments being assigned to other divisions.
