Hitler's Wall
As soon as Hitler had taken over Western Europe, he began construction on a huge wall to prevent invasion from England. His Atlantic Wall would be the biggest obstacle to the Allied troops as they attempted to kick the Nazis out of France.
D-Day
After several delays due to bad weather, General Dwight D. Eisenhower, the supreme commander of the Allied forces, launched approximately 156,000 soldiers across the English Channel on June 6th, 1944. Phony intelligence fooled Hitler into believing that the invasion would land at Pas-de-Calais, but the real force was sent to the beaches of Normandy in northern France.
Here to Stay
The invasion, known as Operation Overlord, was a fierce and deadly battle, costing the lives of tens of thousands of Allied soldiers in just over two months. Despite these losses, the Allies were able to gain a foothold in Nazi territory, and were soon moving soldiers and supplies across the channel at an unstoppable rate.
The End of the Third Reich
By the end of August, the Allies had recaptured a large portion of France, and had taken Paris back from Hitler. From there, the Allied march to Berlin was inevitable. The Nazi dream of world domination was over, and the Germans surrendered on May 7th, 1945.
