Als Nachtrag zu meinem Beitrag [#6] hier ein Link zu einer englischsprachige Seite, die ausführlich berichtet hat:

Operation Sauerkraut - The Story of Cornflakes, Pig Iron and Sheet Iron

Poison Cornflakes for Breakfast

SGM Herbert A. Friedman (Ret.)

Modified versions of this article were first published in the Society of Philatelic Americans Journal, Volume 34, No. 6, February 1972, and the German Postal Specialist, Volume 38, No. 2, February 1987. In addition, because the operation was both clandestine and involved postage stamps and postcards, the propaganda product is very collectable and has been written about in a number of WWII books and articles in the philatelic press. For instance, some of the books that mention the OSS propaganda campaigns are Anthony Cave Brown’s The Secret War Report of the OSS; R. Harris Smith’s OSS – the Secret History of America’s First Central Intelligence Agency; Neal H. Peterson’s From Hitler’s Doorstep – the Wartime Intelligence reports of Allen Dulles 1942-1945 and Kermit Roosevelt’s Top Secret – The Overseas Targets – War Report of the OSS. Of course, there were many more. I just read off the first few titles in my bookcase.
