The President of the United States of America takes pleasure in presenting a Gold Star in lieu of a Second Award of the Navy and Marine Corps Medal to Carpenter William S. Thomas, United States Navy, for heroic conduct as a diver during salvage work at Pearl Harbor following the Japanese attack on 7 December 1941. Carpenter Thomas made dives totaling more than 100 hours under water despite extremely hazardous conditions inside wrecked hulls. He contributed largely to the success of the salvage work.
