D-Day is a historical event that took place on June 6, 1944 during World War II. It was the day when Allied forces landed on the beaches of Normandy, France in a massive operation known as Operation Overlord.
The invasion marked the beginning of the end for Nazi Germany's control over Europe. The Allied forces, consisting of American, British, Canadian, and other troops, faced heavy resistance from German forces but ultimately managed to secure a foothold on the continent.
D-Day was a turning point in the war and is considered one of the most significant military operations in history. It paved the way for the liberation of Western Europe and the eventual defeat of the Axis powers.
