Operation Overlord is arguably WWII’s most important Allied offensive. For Hitler it was his worst nightmare. It was the offensive that would turn the tide of history and mark the beginning of the end for the Nazi regime and Hitler’s reich. Led by Supreme Commander of the Allied Expeditionary Force, Dwight D. Eisenhower and Winston Churchill it would see over 150,000 allied troops enter occupied France, landing on the famous beachheads of Normandy and being dropped behind enemy lines.
