Survivors and crew went about the ship throwing everything moveable over the side to lighten her. I dumped loads of 4 inch shells from ready use lockers. Both sets of quadruple torpedo tubes were turned outboard by hand and fired to lighten ship. On board Petard, six torpedoes were fired at the Japanese submarine, but they all missed, the seventh was fired by local control and did the trick. It blew the submarine in half; I watched the two halves upend and sink with no survivors.
