This song is about D-Day of Operation Overlord.
Operation Overlord was the code name for the invasion of western Europe during World War II by Allied forces. The operation began on 6 June 1944 with the Normandy Landings (commonly known as D-Day) when an airborne assault preceded an amphibious assault. Nearly 160,000 troops crossed the English Channel on 6 June, and more than 3 million troops had landed by the end of August.
