The President of the United States of America takes pleasure in presenting the Navy and Marine Corps Medal to Chief Electrician’s Mate John D. Coggin, United States Navy, for heroic conduct during World War II. During an engagement with a Japanese gunboat, Chief Electrician’s Mate Coggin’s submarine rammed the enemy vessel and it countered with a blast from a heavy machine gun, inflicting great damage. Skillfully maintaining vital electrical equipment as long as possible and later making hasty repairs, he enabled his ship to be kept under control and reach port safely.
