Serving on board the USS 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.
