Torpedoman Second Class, Henry Breault USS O-5
"For heroism and devotion to duty while
serving on board the U.S. Submarine O-5 at the time of the sinking of
that vessel. On the morning of 28 October 1923, the O-5
collided with the steamship Abangarez and sank in less than a
minute. When the collision occurred, Breault was in the torpedo room.
Upon reaching the hatch, he saw that the boat was rapidly sinking. Instead
of jumping overboard to save his own life, he returned to the torpedo
room to the rescue of a shipmate who he knew was trapped in the boat,
closing the torpedo room hatch on himself. Breault and Brown remained
trapped in this compartment until rescued by the salvage party 31 hours
later."
