Awesome information,
Aktungbby. Over 40% accurate and the 1 knot silent running speed of the U-boats meant the Atlantic was safe. Except for the U-boats!
Well, the stuff on the surface was safe, anyway. The only thing a sub could do about that attack was run out from under it and I don't even think a fleet boat could have done that. A Guppy II might have, but wow! Talk about a game changer...
