S-34 (SS-139) Hoping to harass enemy shipping in the newly-conquered Aleutians in June 1942, the S-34 entered the area but ran aground during her first attack. Discovered by an enemy destroyer, the S-34 jettisoned all reserve fuel, floated off the reef, then dived to avoid ramming by the destroyer. On the bottom, she was subjected to a harrowing depth charge attack that forced her to exceed her test depth and experienced an encounter with a giant octopus. Eight days later, she limped back to Dutch Harbor. Every ballast tank was punctured, her screws and rudder were bent on the reef, and depth charge fragments had to be pried from the conning tower fairing.
