[Wumpus Hunter]

As I recall, the book says the guy was caught through the Cullen's (the coast guard guy) insistance to his superiors that SOMETHING was going on. They eventually listened to him, and found where the krauts had buried explosives and stuff in the sand. They also found clothing, and ran the squealer down through a dry cleaning tag or something.

I thought the guy who ratted got executed too, but maybe I'm wrong. I'll try to dig up that book tonight and get you a title.

Actually it seems that two of them were not executed and at least one wrote a book about his experiences. I found this several places on the web.

Here is longer article from Atlantic Monthly on this incident:
