The President of the United States of America takes pleasure in presenting the Navy Cross to Lieutenant Commander Morton Claire Mumma, Jr., United States Navy, for extraordinary heroism in the line of his profession as Commanding Officer of the U.S.S. SAILFISH (SS-192), on the FIRST War Patrol of that submarine in enemy controlled waters of off Luzon, Philippine Islands. On the night of 13 December 1941, the ship made contact with a convoy escorted by three Japanese destroyers. Lieutenant Commander Mumma boldly maneuvered his submarine into striking position despite enemy depth charge counter measures and directed operations and fire to score a torpedo hit on an enemy destroyer. Through his experience and sound judgment Lieutenant Commander Mumma brought his ship safely back to port. His conduct throughout was an inspiration to his officers and men and in keeping with the highest traditions of the United States Naval Service.
