Operation Overlord was the codename for the Allied invasion of Nazi-occupied Western Europe during World War II. This military operation, which began on 6 June 1944, is more commonly known as D-Day.

On the morning of 6 June 1944, thousands of Allied troops landed on five beachheads in Normandy—Utah, Omaha, Gold, Juno, and Sword. The landings involved a combination of American, British, and Canadian forces. Despite facing intense German resistance, particularly at Omaha Beach, the Allies were able to secure the beachheads.

Allied aircraft drop more than 5,000 tonnes of bombs along the coast from Le Havre to Cherbourg, targeting roads, railways and German batteries. Such tactical bombings were also aimed at preventing the Germans from pinpointing the precise landing zone.

Nearly a thousand gliders land, and unload soldiers and equipment. They had to overcome obstacles on the beaches such as “Rommel's Asparagus” – wooden stakes with tripwires – ordered by Germany’s General Rommel. The Allies managed to take control of the strategic Pegasus Bridge in the town of Bénouville, the first place to be liberated.
