Interesting that the original post refers to Dec 1944 ULTRA decrypts related to Bodenplatte, yet the Bodenplatte attack still maintained the element of surprise (while recognising the detection of some of the attackers by conventional means). Does this point to the limitations of UlLTRA?
As mentioned earlier, it is interesting to compare the ability of the codebreakers to successfully attack Luftwaffe Enigma, compared with the complete failure to break Gestapo Enigma messages, or the Kreigsmarine's Barracuda Enigma cypher:

No doubt the Gestapo/Kreigsmarine attitude to radio security was different from the Luftwaffe's.
