The Normandy Landings were the first operations of the Allied invasion of Normandy, also known as Operation Neptune and Operation Overlord, during World War II. The landings commenced on June 6, 1944 (D-Day), beginning at 6:30 British Double Summer Time (H-Hour). In planning, D-Day was the term used for the day of actual landing, which was dependent on final approval. The assault was conducted in two phases: an air assault landing of American, British and Canadian airborne troops shortly after midnight, and an amphibious landing of Allied infantry and armoured divisions on the coast of France commencing at 6:30. The invasion required the transport of soldiers and materiel from the United Kingdom by troop carrying aircraft and ships, the assault landings, air support, naval interdiction of the English Channel and naval fire-support. There were also subsidiary 'attacks' mounted under the codenames Operation Glimmer and Operation Taxable to distract the Kriegsmarine and the German army from the real landing areas.[3] The operation was the largest single-day amphibious invasion of all time, with over 130,000 troops landing on June 6, 1944. 195,700 Allied naval and merchant navy personnel were involved.[4] The landings took place along a stretch of the Normandy coast divided into five sectors: D-Day Utah Beach , D-Day Omaha Beach , D-Day Gold Beach , D-Day Juno Beach and D-Day Sword Beach.

The Invasion of Normandy was the invasion and establishment of Allied forces in Normandy, France, during Operation Overlord in World War II. This article covers from the initial landings on June 6, 1944, until the time of the Allied breakout in late-July.

Allied land forces that saw combat in Normandy on June 6 came from Canada, Free French Forces, the United Kingdom, and the United States. In the weeks following the invasion, Polish forces also participated and there were also contingents from Belgium, Czechoslovakia, Greece, and the Netherlands. Most of the above countries also provided air and naval support, as did the Royal Australian Air Force, Royal New Zealand Air Force and the Royal Norwegian Navy.

The Normandy invasion began with overnight parachute and glider landings, massive air attacks, naval bombardments, an early morning amphibious landing and during the evening the remaining elements of the parachute divisions landed. The "D-Day" forces deployed from bases along the south coast of England, the most important of these being Portsmouth.

The objective of the operation was to create a lodgement that would be anchored in the city of Caen (and later Cherbourg when its deep-water port would be captured). As long as Normandy could be secured, the Western European campaign and the downfall of Nazi Germany could begin. About 6,900 vessels would be involved in the invasion, under the command of Admiral Sir Bertram Ramsay (who had been directly involved in the North African and Italian landings), including 4,100 landing craft. A total of 12,000 aircraft under Air Marshal Sir Trafford Leigh-Mallory were to support the landings, including 1,000 transports to fly in the parachute troops; 10,000 tons of bombs would be dropped against the German defenses, and 14,000 attack sorties would be flown.

Some of the more unusual Allied preparations included armoured vehicles specially adapted for the assault. Developed under the leadership of Maj. Gen. Percy Hobart (Montgomery’s brother-in-law, and an armoured warfare specialist), these vehicles (nicknamed Hobart's Funnies) included "swimming" Duplex Drive Sherman tanks, the Churchill Crocodile flame throwing tank, mine-clearing tanks, bridge-laying tanks and road-laying tanks and the Armoured Vehicle, Royal Engineers (AVRE)–equipped with a large-caliber mortar for destroying concrete emplacements. Some prior testing of these vehicles had been undertaken at Kirkham Priory in Yorkshire, England. The majority would be operated by small teams from the British 79th Armoured Division attached to the various formations.

Allied forces rehearsed their roles for D-Day months before the invasion. On April 28, 1944, in south Devon on the English coast, 638 U.S. soldiers and sailors were killed when German torpedo boats surprised one of these landing exercises, Exercise Tiger.

In the months leading up to the invasion, the Allies conducted a deception operation, Operation Fortitude aimed at misleading the Germans regarding the date and place of the invasion.

There were several leaks prior to or on D-Day. One such leak was the crossword that came out in The Herald and Review six days before the beach landings were to take place. Some of the answers consisted of Overlord, Neptune, Gold and other key terms to the invasions; the US government later declared that this was just a coincidence. Through the Cicero affair, the Germans obtained documents containing references to Overlord, but these documents lacked all detail. Double Cross agents, such as Juan Pujol (code named Garbo), played an important role in convincing the German High Command that Normandy was at best a diversionary attack. U.S. Major General Henry Miller, chief supply officer of the US 9th Air Force, during a party at Coleridge's Hotel in London complained to guests of the supply problems he was having but that after the invasion, which he told them would be before June 15th, supply would be easier. After being told, Eisenhower reduced Miller to Colonel and sent him back to the U.S. where he subsequently retired. Another such leak was Gen. Charles de Gaulle's radio message after D-Day. He, unlike all the other leaders, stated that this invasion was the real invasion. This had the potential to ruin the Allied deceptions Fortitude North and Fortitude South. For example, Gen. Eisenhower referred to the landings as the initial invasion.
