"The President of the United States of America takes pride in presenting a Gold Star in lieu of a Second Award of the Navy Cross (Posthumously) to Lieutenant Commander Andrew Britte Hamm (NSN: 0-82340), United States Navy, for extraordinary heroism in operations against the enemy while serving as Pilot of a carrier-based Navy Dive Bomber of Bombing Squadron ONE (VB-1), attached to the U.S.S. BENNINGTON (CV-20), and deployed over Kure, Japan, on 28 July 1945. While flying a Navy dive bomber plane in which, in the face of one of the heaviest anti-aircraft barrages ever encountered over the Japanese homeland, Lieutenant Commander Hamm pressed home his attack to a very low altitude above the target, released his bomb and scored a direct hit on an enemy aircraft carrier. At the time he was the leader of his Dive Bombing Squadron in its attack on Japanese battleships, heavy and light cruisers, aircraft carriers and smaller warships in the heavily defended Kure Naval Base harbor of the island of Honshu. His own damaging bomb hit and his leadership of the attack in the face of the intense and accurate anti-aircraft fire of the ship and shore batteries contributed materially to the success of the overall attack by the Task Force. His determination and heroic conduct were in keeping with the highest traditions of the United States Naval Service."
Second Navy Cross awarded posthumously.
