On Oct. 5, 1918 there was an explosion on the submarine USS O-5 (Submarine #66) (later SS-66) while at the Brooklyn Naval Shipyard, one man was killed and two others, including the commanding officer, were badly injured. Both men were taken to the Brooklyn Navy Hospital where one soon succumbed to his wound. The commanding officer languished in agony until he was finally released from his torment on Oct. 14.

The boat was repaired and was later the scene of another disaster when on Oct. 28, 1923 she was run down by SS Abangarez in Limon Bay, Canal Zone, again three men were lost. Two men were trapped in her sunken hull, one by choice.

Torpedoman 2nd Class Henry Breault, an ex-Royal Navy seaman, scrambled to the hatch of the boat, but before it went down he returned to the torpedo room to help a trapped man named Brown. He entered the torpedo room and closed the bulkhead door locking both men inside. After more than thirty hours the two men were rescued, Breault was later awarded the Medal of Honor. The O-5 was raised and scrapped.
