The History Channel version had it that the guy who called the FBI was the leader of the Long Island group and thus made the call to let the coast guard guy live. BTW, as I remember it, the History Channel version the FBI brushed off the guy when her first called them and he had to go in in person?

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.
