German success against the M-209 is discussed in David Kahn's "The Codebreakers". It cites a 1962 letter as a source, so presumably this information was in the 1967 edition. In other words, German cryptanalytic success has been public for a long time. Kahn's book has quite a bit of good information on Axis cryptanalytic efforts. Germany was particularly successful, and was using automation to assist their work. One little gem is that Italy managed to pull off an active attack against the Yugoslav Army. They had been reading Yugoslav traffic for awhile, got into a difficult situation, and convinced two divisions they had been ordered to retreat using fake messages. By the time this was discovered and resolved the game was over.
