That was a cool story. I heard the audiobook on the the whole Voyage of the Archer fish. it was interesting. the reason they fired so many Torpedoes is because they had so many Duds. Also they had so many that would immediately start going in circles and go back and actually hit the submarine that fired it. We lost a few submarines that way. I'm thinking it was Espionage but who knows.

But yeah, the skipper of that submarine was responsible for changing our tactics in submarine warfare because he was so successful
