Porter served as a division and corps commander in the Army of the Potomac until he was dismissed from service in January 1863. During Porter's absence, the regiment was commanded by Lieutenant Colonel James P. Sanderson. Porter was succeed as regimental commander by Colonel Oliver L. Shepherd who served as such from January 1863 to December 1870.
