Lately, I've read a lot about how the "Allies" in WW2 (I always found that term strange since the others were also "allies", just not with the USA!) kept breaking all the German ciphers from both the Enigma and Lorenz machines in all their variations and upgrades. From the sound of it, the USA and "Allies" were basically able to "predict" Germany's every move by being able to decrypt their communication messages.
My question is: did Germany not do this in the opposite direction at all? If so, why not? If they did, I sure have never read one darn word about it anywhere. It would be extremely interesting to hear about such efforts and how successful they were.
