re: WW2 is full of great stories, here is one I read yesterday-US Naval Sub related

If you want another interesting sub story you should check out the sinking of the USS S-5. She went down in shallow waters with her arse end sticking up out of the water. The crew worked for days trying to cut through the hull to escape before finally being rescued by a merchant vessel that happened across them. A lot of luck saved that crew. Any number of things could have killed them all but they managed to get out.
