The Allies had knowledge that over 3,000 miles of coastline from Norway to France would in no way be able to be defended. With this knowledge, they tricked Hitler into believing that a joint attack of American, British and Russian forces would occur in Norway. Along with this, they shifted Hitler’s attention toward the French port of Calais, and made it appear that it was the most likely to be attacked. In doing so, this pushed the German forces around, so there was a lower concentration of troops near Normandy, which is where the actual invasion was to take place. Also, the Germans monitored communications for battle plans, they received confirmation from their own spies who were actually double agents working for the Allies. It’s obvious, there was definitely a few tricks up the Allies
