Rear Admiral William Gamble
The destroyer-minelayer Gamble was moored in Middle Loch south of Pearl City on 7 December. She put to sea and at 1632 her No.1 gun opened fire on what was reported to be a surfacing enemy submarine. The submarine immediately submerged and sent up a signal to identify herself as the American submarine Thresher.
