A skull-cracking explosion sounds from the barrel of the deck gun; the shell skims the water, hits the closest destroyer right in the boilers. The destroyer doesn’t blow up, but it does go dead in the water. They take a few more shots at the other destroyer and manage to knock out one of its guns and one of its depth charge launchers. Then the lookouts see airplanes headed their way, and it’s time to dive. Bischoff does one final periscope scan before they go under, and is surprised to see that the destroyer that was trying to evade the torpedoes managed to do so; apparently two of them curved back and hit transport ships instead.
