The weather on D-Day was far from ideal, and the operation had to be delayed 24 hours a further postponement would have meant a delay of at least two weeks, as the invasion planners had requirements for the phase of the moon, the tides, and the time of day that meant only a few days each month were deemed suitable. In the months leading up to the invasion, the Allies conducted a substantial military deception, codenamed Operation Bodyguard, to mislead the Germans as to the date and location of the main Allied landings. Planning for the operation began in 1943.

The operation began the liberation of France (and later Western Europe) and laid the foundations of the Allied victory on the Western Front. Codenamed Operation Neptune and often referred to as D-Day, it was, and still is, the largest seaborne invasion in history. The Normandy landings were the landing operations and associated airborne operations on Tuesday, 6 June 1944 of the Allied invasion of Normandy in Operation Overlord during World War II.

ġ0,000+ casualties 4,414 confirmed dead Ĥ,000–9,000 killed, wounded, missing or captured 170 coastal artillery guns (Includes guns from 100mm to 210mm, as well as 320mm rocket launchers.).
