Rank and organization: First Class Fireman, U.S. Navy. Born: 1835 Washington,
D.C. Accredited to: District of Columbia. G.O. No.: 17, 10 July 1863.
Serving 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, Rush
persisted in penetrating the steam_filled room in order to haul the hot
fires of the furnaces, and continued this action until the gravity of the
situation had been lessened.
