Served on board the U.S.S. Richmond in the attack on Port Hudson, 14 March 1863. Damaged by a 6-inch solid rifle shot which shattered the starboard safety-valve chamber and also damaged the port safety valve, the fireroom of the Richmond immediately became filled with steam to place it in an extremely critical condition. Acting courageously in this crisis, McClelland persisted in penetrating the steam-filled room in order to haul the hot fires of the furnaces and continued this gallant action until the gravity of the situation had lessened.
