The Normandy landings were the landing operations and associated airborne operations on 6 June 1944 of the Allied invasion of Normandy in Operation Overlord during the Second World War. Codenamed Operation Neptune and often referred to as D-Day (after the military term), 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. German leader Adolf Hitler placed Field Marshal Erwin Rommel in command of German forces and developing fortifications along the Atlantic Wall in anticipation of an invasion. US 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 6 June with extensive aerial and naval bombardment as well as an airborne forces—the landing of 24,000 American, Operation Tonga. The early morning aerial assault was soon followed by Allied amphibious landings on the coast of France 06:30. The target stretch of the Normandy coast was divided into five sectors: Utah Beach, Omaha Beach, Gold Beach, Juno Beach, and Sword Beach. 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 land mine and covered with obstacles such as wooden stakes, Czech hedgehog, and barbed wire, making the work of the beach-clearing teams difficult and dangerous. The highest number of casualties was at Omaha, with its high cliffs. At Gold, Juno, and Sword, several fortified towns were cleared in Urban warfare, and two major gun emplacements at Gold were disabled using specialised tanks.
The Allies were able to establish at each of the five landing sites on the first day, but Carentan, Saint-Lô, and Bayeux remained in German hands. 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. German casualties on D-Day have been estimated at 4,000 to 9,000 men. Allied casualties were at least 10,000, with 4,414 confirmed dead.
Instead of an immediate return to France, the western Allies staged offensives in the Mediterranean Theatre of Operations, where British Army were already stationed. By mid-1943, the campaign in North Africa had been won. The Allies then launched the invasion of Sicily in July 1943 and subsequently invaded the Italian mainland in September the same year. By then, Soviet forces were on the offensive and had won a major victory at the Battle of Stalingrad. The decision to undertake a cross-channel invasion within the next year was taken at the Trident Conference in Washington in May 1943. Initial planning was constrained by the number of available landing craft, most of which were already committed in the Mediterranean and Pacific War. At the Tehran Conference in November 1943, Roosevelt and Churchill promised Stalin that they would open the long-delayed second front in May 1944.
The Allies considered four sites for the landings: Brittany, the Cotentin Peninsula, Normandy, and the Pas-de-Calais. As Brittany and Cotentin are peninsulas, it would have been possible for the Germans to cut off the Allied advance at a relatively narrow isthmus, so these sites were rejected. With the Pas-de-Calais being the closest point in continental Europe to Britain, the Germans considered it to be the most likely initial landing zone, so it was the most heavily fortified region. But it offered few opportunities for expansion, as the area is bounded by numerous rivers and canals, whereas, landings on a broad front in Normandy would permit simultaneous threats against the port of Cherbourg, coastal ports further west in Brittany, and an overland attack towards Paris and eventually into Germany. Normandy was hence chosen as the landing site. The most serious drawback of the Normandy coast—the lack of port facilities—would be overcome through the development of artificial . A series of modified tanks, nicknamed Hobart's Funnies, dealt with specific requirements expected for the Normandy Campaign such as mine clearing, demolishing bunkers, and mobile bridging.
The Allies planned to launch the invasion on 1 May 1944. The initial draft of the plan was accepted at the Quebec Conference in August 1943. General Dwight D. Eisenhower was appointed commander of the Supreme Headquarters Allied Expeditionary Force. General Bernard Montgomery was named commander of the 21st Army Group, which comprised all land forces involved in the invasion. On 31 December 1943, Eisenhower and Montgomery first saw the plan, which proposed amphibious landings by three divisions with two more divisions in support. The two generals insisted that the scale of the initial invasion be expanded to five divisions, with airborne descents by three additional divisions, to allow operations on a wider front and to hasten the capture of Cherbourg. The need to acquire or produce extra landing craft for the expanded operation meant that the invasion had to be delayed to June. Eventually, thirty-nine Allied divisions would be committed to the Battle of Normandy: twenty-two American, twelve British, three Canadian, one Polish, and one French, totalling over a million troops.
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 Beach and and the Canadians at Juno Beach would protect the US flank and attempt to establish airfields near Caen on the first day. (A sixth beach, code-named "Band", was considered to the east of the Orne). 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. Montgomery envisaged a ninety-day battle, lasting until all Allied forces reached the River Seine.
Many of the German radar stations on the French coast were destroyed in preparation for the landings. In addition, on the night before the invasion, a small group of Special Air Service operators deployed dummy paratroopers over Le Havre and Isigny-sur-Mer. These dummies led the Germans to believe that an additional airborne landing had occurred. On that same night, in Operation Taxable, No. 617 Squadron RAF dropped strips of "window", metal foil that caused a radar return which was mistakenly interpreted by German radar operators as a naval convoy near Le Havre. The illusion was bolstered by a group of small vessels towing . A similar deception was undertaken near Boulogne-sur-Mer in the Pas de Calais area by No. 218 Squadron RAF in Operation Glimmer.
Group Captain James Stagg of the Royal Air Force (RAF) met Eisenhower on the evening of 4June. He and his meteorological team predicted that the weather would improve enough for the invasion to proceed on 6 June. The next available dates with the required tidal conditions (but without the desirable full moon) would be two weeks later, from 18 to 20 June. Postponement of the invasion would have required recalling men and ships already in position to cross the English Channel and would have increased the chance that the invasion plans would be detected. After much discussion with the other senior commanders, Eisenhower decided that the invasion should go ahead on 6 June. A major storm battered the Normandy coast from 19 to 22 June, which would have made the beach landings impossible.
Allied control of the Atlantic meant German meteorologists had less information than the Allies on incoming weather patterns. As the Luftwaffe meteorological centre in Paris was predicting two weeks of stormy weather, many Wehrmacht commanders left their posts to attend war games in Rennes, and men in many units were given leave. Field Marshal Erwin Rommel returned to Germany for his wife's birthday and to petition Hitler for additional Panzers divisions.
In early 1944, the German Western Front (OB West) was significantly weakened by personnel and materiel transfers to the Eastern Front. During the Soviet Dnieper–Carpathian offensive (24 December 1943 – 17 April 1944), the German High Command was forced to transfer the entire II SS Panzer Corps from France, consisting of the 9th and 10th SS Panzer Divisions, as well as the 349th Infantry Division, 507th Heavy Panzer Battalion and the 311th and 322nd StuG Assault Gun Brigades. All told, the German forces stationed in France were deprived of 45,827 troops and 363 tanks, assault guns, and self-propelled anti-tank guns.
The 1st SS Panzer Division "Leibstandarte SS Adolf Hitler", 9th, 11th, 19th and 116th Panzer divisions, alongside the 2nd SS Panzer Division "Das Reich", had only arrived in France in March–May 1944 for extensive refit after suffering heavy losses during the Dnieper-Carpathian operation. Seven of the eleven panzer or italic=no divisions stationed in France were not fully operational or only partially mobile in early June 1944.
German Supreme commander: Adolf Hitler
Allied forces at Gold and Juno faced the following elements of the 352nd Infantry Division:
Rommel believed that the Normandy coast could be a possible landing point for the invasion, so he ordered the construction of extensive defensive works along that shore. In addition to concrete gun emplacements at strategic points along the coast, he ordered wooden stakes, metal tripods, mines, and large anti-tank obstacles to be placed on the beaches to delay the approach of landing craft and impede the movement of tanks. Expecting the Allies to land at high tide so that the infantry would spend less time exposed on the beach, he ordered many of these obstacles to be placed at the high water mark. Tangles of barbed wire, , and the removal of ground cover made the approach hazardous for infantry. On Rommel's order, the number of mines along the coast was tripled. The Allied air offensive over Germany had crippled the Luftwaffe and established air supremacy over western Europe, so Rommel knew he could not expect effective air support. The Luftwaffe could muster only 815 aircraft over Normandy in comparison to the Allies' 9,543. Rommel arranged for booby-trapped stakes known as Rommelspargel (Rommel's asparagus) to be installed in meadows and fields to deter airborne landings.
German armaments minister Albert Speer notes in his 1969 autobiography that the German high command, concerned about the susceptibility of the airports and port facilities along the North Sea coast, held a conference on 6–8 June 1944 to discuss reinforcing defences in that area. Speer wrote:
The First Army contingent totalled approximately 73,000 men, including 15,600 from the airborne divisions.
Overall, the Second Army contingent consisted of 83,115 men, 61,715 of them British. The British and Commonwealth air and naval support units included a large number of personnel from Allied nations, including several RAF squadrons manned almost exclusively by overseas air crew. For example, the Australian contribution to the operation included a regular Royal Australian Air Force (RAAF) squadron, nine Article XV squadrons, and hundreds of personnel posted to RAF units and RN warships. The RAF supplied two-thirds of the aircraft involved in the invasion.
79th Armoured Division: Major General Percy Hobart provided specialised armoured vehicles which supported the landings on all beaches in Second Army's sector.
The resistance was alerted to carry out these tasks by messages personnels transmitted by the Radio Londres from London. Several hundred of these messages, which might be snippets of poetry, quotations from literature, or random sentences, were regularly transmitted, Steganography the few that were actually significant. In the weeks preceding the landings, lists of messages and their meanings were distributed to resistance groups. 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.
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."
The invasion fleet, which was drawn from eight different navies, comprised 6,939 vessels: 1,213 warships, 4,126 landing craft of various types, 736 ancillary craft, and 864 merchant vessels. The majority of the fleet was supplied by the UK, which provided 892 warships and 3,261 landing craft. In total there were 195,700 naval personnel involved; of these 112,824 were from the Royal Navy with another 25,000 from the Merchant Navy; 52,889 were American; and 4,998 sailors from other allied countries. The invasion fleet was split into the Western Naval Task Force (under Admiral Alan G. Kirk) supporting the US sectors and the Eastern Naval Task Force (under Admiral Sir Philip Vian) in the British and Canadian sectors. Available to the fleet were five battleships, 20 cruisers, 65 destroyers, and two monitors. German ships in the area on D-Day included three torpedo boats, 29 fast attack craft, 36 , and 35 auxiliary and patrol boats. The Germans also had several available, and all the approaches had been heavily mined.
Minesweepers began clearing channels for the invasion fleet shortly after midnight and finished just after dawn without encountering the enemy. The Western Task Force included the battleships , , and , plus eight cruisers, twenty-eight destroyers, and one monitor. The Eastern Task Force included the battleships and and the monitor , twelve cruisers, and thirty-seven destroyers. Naval bombardment of areas behind the beach commenced at 05:45, while it was still dark, with the gunners switching to pre-assigned targets on the beach as soon as it was light enough to see, at 05:50. Since troops were scheduled to land at Utah and Omaha starting at 06:30 (an hour earlier than the British beaches), these areas received only about 40 minutes of naval bombardment before the assault troops began to land on the shore.
The US 82nd and 101st Airborne Divisions were assigned to objectives west of Utah Beach, where they hoped to capture and control the few narrow causeways through terrain that had been intentionally flooded by the Germans. Reports from Allied intelligence in mid-May of the arrival of the German 91st Infantry Division meant the intended drop zones had to be shifted eastward and to the south. The British 6th Airborne Division, on the eastern flank, was assigned to capture intact the bridges over the Caen Canal and River Orne, destroy five bridges over the Dives to the east, and destroy the Merville Gun Battery overlooking Sword Beach. Free French paratroopers from the British SAS Brigade were assigned to objectives in Brittany from 5 June until August in Operations Dingson, Samwest, and Operation Cooney.
BBC war correspondent Robert Barr described the scene as paratroopers prepared to board their aircraft:
Paratroops from 101st Airborne were dropped beginning around 01:30, tasked with controlling the causeways behind Utah Beach and destroying road and rail bridges over the Douve River. The C-47s could not fly in a tight formation because of thick cloud cover, and many paratroopers were dropped far from their intended landing zones. Many planes came in so low that they were under fire from both flak and machine-gun fire. Some paratroopers were killed on impact when their parachutes did not have time to open, and others drowned in the flooded fields. Gathering together into fighting units was made difficult by a shortage of radios and by the bocage terrain, with its , stone walls, and marshes. Some units did not arrive at their targets until afternoon, by which time several of the causeways had already been cleared by members of the 4th Infantry Division moving up from the beach.
Troops of the 82nd Airborne began arriving around 02:30, with the primary objective of capturing two bridges over the River Merderet and destroying two bridges over the Douve. On the east side of the river, 75 per cent of the paratroopers landed in or near their drop zone, and within two hours they captured the important crossroads at Sainte-Mère-Église (the first town liberated in the invasion) and began working to protect the western flank. Because of the failure of the pathfinders to accurately mark their drop zone, the two regiments dropped on the west side of the Merderet were extremely scattered, with only four per cent landing in the target area. Many landed in nearby swamps, with much loss of life. Paratroopers consolidated into small groups, usually a combination of men of various ranks from different units, and attempted to concentrate on nearby objectives. They captured but failed to hold the Merderet River bridge at La Fière, and fighting for the crossing continued for several days.
Reinforcements arrived by military glider around 04:00 (Mission Chicago and Mission Detroit), and 21:00 (Mission Keokuk and Mission Elmira), bringing additional troops and heavy equipment. Like the paratroopers, many landed far from their drop zones. Even those that landed on target experienced difficulty, with heavy cargo such as Willys MB shifting during landing, crashing through the wooden fuselage, and in some cases crushing personnel on board.
After 24 hours, only 2,500 men of the 101st and 2,000 of the 82nd Airborne were under the control of their divisions, approximately a third of the force dropped. This wide dispersal had the effect of confusing the Germans and fragmenting their response. The 7th Army received notification of the parachute drops at 01:20, but Rundstedt did not initially believe that a major invasion was underway. The destruction of radar stations along the Normandy coast in the week before the invasion meant that the Germans did not detect the approaching fleet until 02:00.
Only 160 men out of the 600 members of the 9th Battalion tasked with eliminating the enemy battery at Merville arrived at the rendezvous point. Lieutenant Colonel Terence Otway, in charge of the operation, decided to proceed regardless, as the emplacement had to be destroyed by 06:00 to prevent it firing on the invasion fleet and the troops arriving on Sword Beach. In the Battle of Merville Gun Battery, Allied forces disabled the guns with plastic explosives at a cost of 75 casualties. The emplacement was found to contain 75 mm guns rather than the expected 150 mm heavy coastal artillery. Otway's remaining force withdrew with the assistance of a few members of the 1st Canadian Parachute Battalion.
With this action, the last of the D-Day goals of the British 6th Airborne Division was achieved. They were reinforced at 12:00 by commandos of the 1st Special Service Brigade, who landed on Sword Beach, and by the 6th Airlanding Brigade, who arrived in gliders at 21:00 in Operation Mallard.
The initial assault battalions were quickly followed by 28 DD tanks and several waves of engineer and demolition teams to remove beach obstacles and clear the area directly behind the beach of obstacles and mines. Gaps were blown in the sea wall to allow quicker access for troops and tanks. Combat teams began to exit the beach at around 09:00, with some infantry wading through the flooded fields rather than travelling on the single road. They skirmished throughout the day with elements of the 919th Grenadier Regiment, who were armed with antitank guns and rifles. The main strongpoint in the area and another to the south were disabled by noon. The 4th Infantry Division did not meet all of their D-Day objectives at Utah Beach, partly because they had arrived too far to the south, but they landed 21,000 troops at the cost of only 197 casualties.
The Rangers fended off numerous counter-attacks from the German 914th Grenadier Regiment. The men were isolated, and some were captured. By dawn on 7 June, Rudder had only 90 men able to fight. Relief did not arrive until 8 June, when members of the 743rd Tank Battalion and others arrived. By then, Rudder's men had run out of ammunition and were using captured German weapons. Several men were killed as a result, because the German weapons made a distinctive noise, and the men were mistaken for the enemy. By the end of the battle, the Rangers casualties were 135 dead and wounded, while German casualties were 50 killed and 40 captured. An unknown number of French collaborators were executed.
Casualties were around 2,000, as the men were subjected to fire from the cliffs above. Problems clearing the beach of obstructions led to the beachmaster calling a halt to further landings of vehicles at 08:30. A group of destroyers arrived around this time to provide fire support so landings could resume. Exit from the beach was possible only via five heavily defended gullies, and by late morning barely 600 men had reached the higher ground. By noon, as the artillery fire took its toll and the Germans started to run out of ammunition, the Americans were able to clear some lanes on the beaches. They also started clearing the gullies of enemy defences so that vehicles could move off the beach. The tenuous beachhead was expanded over the following days, and the D-Day objectives for Omaha were accomplished by 9 June.
Meanwhile, infantry began clearing the heavily fortified houses along the shore and advanced on targets further inland. The No. 47 (Royal Marine) Commando moved toward the small port at Port-en-Bessin and captured it the following day in the Battle of Port-en-Bessin. Company Sergeant Major Stanley Hollis received the only Victoria Cross awarded on D-Day for his actions including attacking two pillboxes at the Mont Fleury high point. On the western flank, the 1st Battalion, Royal Hampshire Regiment captured Arromanches (future site of Mulberry "B"), and contact was made on the eastern flank with the Canadian forces at Juno. Bayeux was not captured the first day because of stiff resistance from the 352nd Infantry Division. Allied casualties at Gold Beach are estimated at 1,000.
Major German strongpoints with 75 mm guns, machine-gun nests, concrete fortifications, barbed wire, and mines were located at Courseulles-sur-Mer, St Aubin-sur-Mer, and Bernières-sur-Mer. The towns had to be cleared in house-to-house fighting. Soldiers on their way to Bény-sur-Mer, inland, discovered that the road was well covered by machine gun emplacements that had to be outflanked before the advance could proceed. Elements of the 9th Canadian Infantry Brigade advanced to within sight of the Carpiquet airfield late in the afternoon, but by this time their supporting armour was low on ammunition so the Canadians dug in for the night. The airfield was not captured until a month later as the area became the scene of fierce fighting. By nightfall, the contiguous Juno and Gold beachheads covered an area wide and deep. Casualties at Juno were 961 men.
The 'Morris' strongpoint near Colleville-sur-Orne was captured after about an hour of fighting. The nearby Hillman Fortress, headquarters of the 736th Infantry Regiment, was a large complex defensive work that had come through the morning's bombardment essentially undamaged. It was not captured until 20:15. The 2nd Battalion, King's Shropshire Light Infantry began advancing to Caen on foot, coming within a few kilometres of the town, but had to withdraw due to lack of armour support. At 16:00, the 21st Panzer Division mounted a counter-attack between Sword and Juno and nearly succeeded in reaching the Channel. It met stiff resistance from the British 3rd Division and was soon recalled to assist in the area between Caen and Bayeux. Estimates of Allied casualties on Sword Beach are as high as 1,000.
The Allied invasion plans had demanded a rapid build-up of troops and the establishment of a secure bridgehead, which was achieved with fewer casualties than expected. The plan had also called for the capture of Carentan, Saint-Lô, Caen, and Bayeux on the first day, with all the beaches (other than Utah) linked with a front line from the beaches; none of these latter objectives were achieved. At Utah the 4th Division made significant progress inland, making a rendezvous with the airborne troops, and the British and Canadians were between inland. The five beachheads were not connected until 12 June, by which time the Allies held a front around long and deep. Caen, a major objective, was still in German hands at the end of D-Day and would not be completely captured until 21 July. The Germans had ordered French civilians other than those deemed essential to the war effort to leave potential combat zones in Normandy. Civilian casualties on D-Day and D+1 are estimated at 3,000.
The Allied victory in Normandy stemmed from several factors. German preparations along the Atlantic Wall were only partially finished; shortly before D-Day Rommel reported that construction was only 18 per cent complete in some areas as resources were diverted elsewhere. The deceptions undertaken in Operation Fortitude were successful, leaving the Germans obliged to defend a huge stretch of coastline. Rommel was in Berlin and the forecasted stormy weather meant that some other German commanders and troops were not present in Normandy. The Allies achieved and maintained air supremacy, which meant that the Germans were unable to make observations of the preparations underway in Britain and were unable to interfere via bomber attacks. Infrastructure for transport in France was severely disrupted by Allied bombers and the French Resistance, making it difficult for the Germans to bring up reinforcements and supplies. Some of the opening bombardment was off-target or not concentrated enough to have any impact, but the specialised armour worked well except on Omaha (where most of it had been lost at sea), providing close artillery support for the troops as they disembarked onto the beaches. Indecisiveness and an overly complicated command structure on the part of the German high command were also factors in the Allied success. German forces retreated east across the Seine on 30 August 1944, marking the close of Operation Overlord.
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. Sections of Mulberry HarbourB still sit in the sea at Arromanches, and the well-preserved Longues-sur-Mer battery is nearby. The Juno Beach Centre, opened in 2003, was funded by the Canadian federal and provincial governments, France, and Canadian veterans. The British Normandy Memorial above Gold Beach was designed by the architect Liam O'Connor and opened in 2021.
