order CAPT Cromwell to activate the wolfpack. When failed to acknowledge the message, even after several repetitions, she was assumed – correctly – to have been lost at sea. It wasn't until after the war that the details of her loss – and that of John Cromwell – to enemy action became known from both Japanese sources and surviving crewmembers who had been prisoners of war. had actually arrived on station on 16 November and made radar contact with a large, high-speed convoy on the night of the 18th. After making a fast surface run to get ahead of the quarry, LCDR Connaway submerged for an attack at dawn. As he started his final approach, however, his periscope was spotted by the enemy, and Connaway was forced to take deep and allow the convoy to pass overhead. Then, he surfaced again to attempt another end run in broad daylight. Unfortunately, the Japanese destroyer Yamagumo had lagged behind the convoy specifically to counter such a move and, after forcing Connaway to make a quick dive, dropped a pattern of depth charges that – unbeknownst to the crew – damaged the depth gauge. went deep and laid low for several hours. Around noon, Connaway attempted to bring back to periscope depth, seeking another opportunity to attack. However, while coming up, the broken depth gauge stuck at 125 feet, confusing the diving officer, and causing the boat to broach the surface in full view of Yamagumo, which was still patrolling the area. As crash-dived again, the Japanese destroyer dropped a string of 18 depth charges, severely damaging the boat and causing temporary loss of depth control. Numerous leaks developed in the hull, and so much water came on board that the submarine was forced to run at high speed to maintain depth. This invited a second Japanese attack that did even more damage. At this point, Connaway concluded that the only chance of saving his crew was to come to the surface and fight it out there. surfaced, and with decks awash, her crew manned the deck guns. The result of this uneven contest was hardly in doubt. Yamagumo's first salvo hit 's conning tower, killing the entire bridge watch team, including Connaway and his executive and gunnery officers. The gun crew died almost instantly from shrapnel. The senior ship's officer surviving, a reserve lieutenant, ordered the boat scuttled and the crew to
