Fortress Europe
Fortress Europe (German: Festung Europa) was a military propaganda term used by both sides of World War II which referred to the areas of Continental Europe occupied by Nazi Germany, as opposed to the United Kingdom across the Channel. == World War II defences == In British phraseology, Fortress Europe meant the battle honour accorded to Royal Air Force and Allied squadrons during the war, but to qualify, operations had to be made by aircraft based in Britain against targets in Germany, Italy, and other parts of German-occupied Europe in the period from the fall of France to the Normandy invasion.
