One of the most interesting questions of WWII history is whether the Germans could have taken measures that would lead to a defeat of the Allies in the West. Many authors and historians claim that the Germans had huge forces in the West but were prevented from moving them to Normandy because of a deception plan. I have criticized this belief. The problem is that the positioning of German divisions in the West does not correspond with that theory.
Why did the Germans place new units in Normandy? Why did they position powerful mobile units close by? Weren’t they expecting an Allied assault against the Calais area?
It seems that by May ’44 their attention had definitely shifted towards the Normandy-Brittany areas.
Hitler in a talk with Japanese ambassador Oshima on 27 May 1944 said that diversionary attacks would take place in Norway, Denmark, the Southern part of Western France and the coasts of the French Mediterranean. A major allied assault would come in either Normandy or Brittany. This would be a serious operation but once the Allies had consolidated their position it would probably be followed by the main invasion in the Calais area.
