Hi, Howard. I think you're using *way* too many initials here. You gotta remember that the average reader doesn't have a clue as to what HUMINT, IMINT, and SIGINT mean. And the first mention of WWII should be spelled out.... Best, Hayford Peirce 16:54, 5 June 2008 (CDT)

OK, will expand and link.

As far as "all" German spies, I tend to believe it, for several reasons. First, no one has ever surfaced with a credible story of being an uncaught spy. Second, nothing in captured records or debriefings indicated the Germans were getting any HUMINT that didn't come from a controlled source. Third, the Abwehr (military intelligence, before it was broken up due to involvement in anti-Hitler activities) was running the spies, and that their message traffic was in an Enigma version that was being read. Fourth (a little softer) the Germans bought the Plan Bodyguard strategic deception that Double-Cross supported; before Normandy, all German eyes were on the Pas de Calais, which was the fake invasion. While the local generals concluded Normandy was the real thing, Hitler still wouldn't believe it wasn't a feint and the real major invasion was yet to come.

Somewhat supporting was that a certain number of German high-altitude reconnaissance planes were allowed to get back to Germany, and the main reconnaissance effort came exactly where Bodyguard wanted the Germans to believe the (mythical) First United States Army Group (FUSAG), under Patton, was staging.

Thanks, Hayford. Should I have mentioned RUMINT and ININT, or Rumor Intelligence & Initial Intelligence? Seriously, there get to be some fairly exotic tradecraft techniques to signal if one is under enemy control, and for a competent counterespionage organization to prevent such warnings.

Good note; good example of talk page vs. article collaboration. While there are some British records that may not declassify until 75 years after 1945, or the death of the last participant, I'd really be surprised if anything surfaced at this point. It's indirect evidence, but another confirmation is that the Nazis seemed to accept all of their doubled agent reports, and not take actions inconsistent with them.

The agents, by and large, were not especially ideological; at least the ones who were doubled. XX gave them the choice "double or die", and some, indeed, preferred the rope. Howard C. Berkowitz 13:12, 6 June 2008 (CDT)
