It came under fire for the first time at Fort Bisland, losing 7 killed and wounded, and a detachment under Capt. Conrady skirmished at Breaux bridge, Bayou Teche. The regiment took an active part in the siege of Port Hudson, where its total loss was 92 killed and wounded. Among the mortally wounded in the second assault on June 14, was Maj. Galloway.
