This I find difficult to believe:
Was PzGruppe west HQ so conspicuous that they really believed it could have been spotted, let alone properly identified, from the air?No German suspicions were aroused about Allied code breaking, because a reconnaissance aircraft had been seen before the raid.[9]
Wouldn't the scale of the attack have raised a few eyebrows? I understand the Germans lived under the constant threat from the air, but this wasn't a causal strafing from a flight of Spitfires.
