There’s a new book out by Marc Milner dealing with the planning and the first few days of the Normandy invasion. I’ve gotten through the first hundred pages and so far its being a good read, with a lot of interesting information. He makes the case the Canadians real role in Normandy was to form two brigade fortress positions and defeat the expected counter attacks by the German Panzer Divisions in either side of the Mue river valley.
