Normandy landings
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. Codenamed Operation Neptune and often referred to as D-Day, it is the largest seaborne invasion in history. The operation began the liberation of France, and the rest of Western Europe, and laid the foundations of the Allied victory on the Western Front.

Planning for the operation began in 1943. 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. The weather on the day selected for D-Day was not 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 planners had requirements for the phase of the moon, the tides, and time of day, that meant only a few days each month were deemed suitable. Adolf Hitler placed Field Marshal Erwin Rommel in command of German forces and developing fortifications along the Atlantic Wall in anticipation of an invasion. U.S. President Franklin D. Roosevelt placed Major General Dwight D. Eisenhower in command of Allied forces.
The invasion began shortly after midnight on the morning of June the 6th with extensive aerial and naval bombardment as well as an airborne assault—the landing of 24,000 American, British, and Canadian airborne troops. The early morning aerial assault was soon followed by Allied amphibious landings on the coast of France ca. 06:30 AM. The target 50-mile (80 km) stretch of the Normandy coast was divided into five sectors: Utah, Omaha, Gold, Juno, and Sword. Strong winds blew the landing craft east of their intended positions, particularly at Utah and Omaha.
The men landed under heavy fire from gun emplacements overlooking the beaches, and the shore was mined and covered with obstacles such as wooden stakes, metal tripods, and barbed wire, making the work of the beach-clearing teams difficult and dangerous. Casualties were heaviest at Omaha, with its high cliffs. At Gold, Juno, and Sword, several fortified towns were cleared in house-to-house fighting, and two major gun emplacements at Gold were disabled using specialised tanks.
The Allies failed to achieve any of their goals on the first day. Carentan, Saint-Lô, and Bayeux remained in German hands, and Caen, a major objective, was not captured until 21 July. Only two of the beaches (Juno and Gold) were linked on the first day, and all five beachheads were not connected until 12 June; however, the operation gained a foothold that the Allies gradually expanded over the coming months. German casualties on D-Day have been estimated at 4,000 to 9,000 men. Allied casualties were documented for at least 10,000, with 4,414 confirmed dead.
Operations
Operation Overlord was the name assigned to the establishment of a large-scale lodgement on the continent. The first phase, the amphibious invasion and establishment of a secure foothold, was codenamed Operation Neptune.[26] To gain the air superiority needed to ensure a successful invasion, the Allies undertook a bombing campaign (codenamed Operation Pointblank) that targeted German aircraft production, fuel supplies, and airfields.[26] Elaborate deceptions, codenamed Operation Bodyguard, were undertaken in the months leading up to the invasion to prevent the Germans from learning the timing and location of the invasion.[32]
The landings were to be preceded by airborne operations near Caen on the eastern flank to secure the Orne River bridges and north of Carentan on the western flank. The Americans, assigned to land at Utah Beach and Omaha Beach, were to attempt to capture Carentan and Saint-Lô the first day, then cut off the Cotentin Peninsula and eventually capture the port facilities at Cherbourg. The British at Sword and Gold Beaches and Canadians at Juno Beach would protect the U.S. flank and attempt to establish airfields near Caen on the first day.[33][34] (A sixth beach, code-named "Band", was considered to the east of the Orne.[35]) A secure lodgement would be established with all invading forces linked together, with an attempt to hold all territory north of the Avranches-Falaise line within the first three weeks.[33][34] Montgomery envisaged a ninety-day battle, lasting until all Allied forces reached the River Seine.[36]
Armoured reserves
Rommel believed that Germany's best chance was to stop the invasion at the shore. He requested that the mobile reserves, especially tanks, be stationed as close to the coast as possible. Rundstedt, Geyr, and other senior commanders objected. They believed that the invasion could not be stopped on the beaches. Geyr argued for a conventional doctrine: keeping the Panzer formations concentrated in a central position around Paris and Rouen and deploying them only when the main Allied beachhead had been identified. He also noted that in the Italian Campaign, the armoured units stationed near the coast had been damaged by naval bombardment. Rommel's opinion was that because of Allied air supremacy, the large-scale movement of tanks would not be possible once the invasion was under way. Hitler made the final decision, which was to leave three Panzer divisions under Geyr's command and give Rommel operational control of three more as reserves. Hitler took personal control of four divisions as strategic reserves, not to be used without his direct orders.[79][80][81]
Through the London-based État-major des Forces Françaises de l'Intérieur (French Forces of the Interior), the British Special Operations Executive orchestrated a campaign of sabotage to be implemented by the French Resistance. The Allies developed four plans for the Resistance to execute on D-Day and the following days:
The resistance was alerted to carry out these tasks by messages personnels transmitted by the BBC's French service from London. Several hundred of these messages, which might be snippets of poetry, quotations from literature, or random sentences, were regularly transmitted, masking the few that were actually significant. In the weeks preceding the landings, lists of messages and their meanings were distributed to resistance groups.[94] An increase in radio activity on 5 June was correctly interpreted by German intelligence to mean that an invasion was imminent or underway. However, because of the barrage of previous false warnings and misinformation, most units ignored the warning.[95][96]
A 1965 report from the Counter-insurgency Information Analysis Center details the results of the French Resistance's sabotage efforts: "In the southeast, 52 locomotives were destroyed on 6 June and the railway line cut in more than 500 places. Normandy was isolated as of 7 June."[97]
At Omaha Beach, parts of the Mulberry harbour are still visible, and a few of the beach obstacles remain. A memorial to the U.S. National Guard sits at the location of a former German strongpoint. Pointe du Hoc is little changed from 1944, with the terrain covered with bomb craters and most of the concrete bunkers still in place. The Normandy American Cemetery and Memorial is nearby, in Colleville-sur-Mer.[210] A museum about the Utah landings is located at Sainte-Marie-du-Mont, and there is one dedicated to the activities of the U.S. airmen at Sainte-Mère-Église. Two German military cemeteries are located nearby.[211]
Pegasus Bridge, a target of the British 6th Airborne, was the site of some of the earliest action of the Normandy landings. The bridge was replaced in 1994 by one similar in appearance, and the original is housed on the grounds of a nearby museum complex.[212] Sections of Mulberry Harbour B still sit in the sea at Arromanches, and the well-preserved Longues-sur-Mer battery is nearby.[213] The Juno Beach Centre, opened in 2003, was funded by the Canadian federal and provincial governments, France, and Canadian veterans.[214] The British Normandy Memorial above Gold Beach was designed by the architect Liam O'Connor and opened in 2021.[215]
