The german military administration in France ended with the Liberation of France after the Normandy and Provence landings. It formally existed from May 1940 to December 1944, though most of its territory had been liberated by the allies by the end of summer 1944.
One of the main reasons for the success of the D-Day landings was the element of surprise, the incredibly huge invasion force, congregating along the south coast of England went undetected by German Intelligence. Hitler's Generals believed the stormy weather meant it would be mission impossible, and it almost was.
