Timeline: 1944

The Normandy landings, codenamed Operation Neptune, were the landing operations of the Allied invasion of Normandy, in Operation Overlord, during World War II. The landings commenced on Tuesday, 6 June 1944 (D-Day), beginning at 6:30 am British Double Summer Time (GMT+2). In planning, as for most Allied operations, the term D-Day was used for the day of the actual landing, which was dependent on final approval.

The landings were conducted in two phases: an airborne assault landing of 24,000 British, American and Canadian airborne troops shortly after midnight, and an amphibious landing of Allied infantry and armoured divisions on the coast of France starting at 6:30 am. Surprise was achieved thanks to inclement weather and a comprehensive deception plan implemented in the months before the landings, Operation Bodyguard, to distract German attention from the possibility of landings in Normandy. A key success was to convince Adolf Hitler that the landings would actually occur to the north at the Pas-de-Calais. There were also decoy operations taking place simultaneously with the landings under the codenames Operation Glimmer and Operation Taxable to distract the German forces from the real landing areas.

Supreme Commander of the Allied Expeditionary Forces was General Dwight D. Eisenhower while overall command of ground forces (21st Army Group) was given to General Bernard Montgomery. The operation, planned by a team under Lieutenant-General Frederick Morgan, was the largest amphibious invasion in world history and was executed by land, sea and air elements under direct British-American command with over 160,000[6] soldiers landing on 6 June 1944: 73,000 Americans, 61,715 British and 21,400 Canadians. 195,700[8] Allied naval and merchant navy personnel in over 5,000 ships were also involved. The invasion required the transport of soldiers and materiel from the United Kingdom by troop-laden aircraft and ships, the assault landings, air support, naval interdiction of the English Channel and naval fire-support. The landings took place along a 50-mile (80 km) stretch of the Normandy coast divided into five sectors: Utah, Omaha, Gold, Juno, and Sword.

Prior to the Events Edit

The Allied invasion was detailed in several overlapping operational plans. According to the D-Day museum: "The armed forces used code names to refer to the planning and execution of specific military operations. Operation Overlord was the codename for the Allied invasion of northwest Europe. The assault phase of Operation Overlord was known as Operation Neptune. Operation Neptune began on D-Day (6 June 1944) and ended on 30 June 1944. By this time, the Allies had established a firm foothold in Normandy. Operation Overlord also began on D-Day, and continued until Allied forces crossed the River Seine on 19 August 1944."

Just prior to the invasion, General Eisenhower transmitted a now-historic message to all members of the Allied Expeditionary Force. It read, in part, "You are about to embark upon the great crusade, toward which we have striven these many months."[9] In his pocket was a statement, never used, to be read out in case the invasion failed.

Allied PlanningEdit

Under the high-level plan Operation Bodyguard, the Allies had instituted a comprehensive and complex series of deceptions which led to the landings achieving strategic and tactical surprise. One of the key successes of these operations was Operation Fortitude South which convinced Hitler that the Allies' plan was for their main attack to be across the Straits of Dover by the fictitious First United States Army Group to be led by George S. Patton and that the Normandy landings were a diversionary tactic. The fiction was maintained after the Normandy landings to the effect that Hitler, still believing an attack was imminent across the straits, was unwilling, until it was too late, to reinforce his troops in Normandy with forces placed to defend the Pas de Calais.

Particularly relevant to the Normandy landings was the use of heavy bombers in Operations Glimmer and Taxable which flew in highly precise patterns over the Straits of Dover, to drop radar-reflecting aluminium strips ("window", now known as chaff), to create a picture on German radar of an invasion fleet moving across the straits simultaneously with the arrival of the invasion fleet in Normandy.

WeatherEdit

Only 10 days each month were suitable for launching the operation: a day near the full Moon was needed both for illumination during the hours of darkness and for the spring tide, the former to illuminate navigational landmarks for the crews of aircraft, gliders and landing craft, and the latter to provide the deepest possible water to help safe navigation over defensive obstacles placed by the German forces in the surf on the seaward approaches to the beaches. A full moon occurred on 6 June. Allied Expeditionary Force Supreme Commander Dwight D. Eisenhower had tentatively selected 5 June as the date for the assault. The weather was fine during most of May, but deteriorated in early June. On 4 June, conditions were clearly unsuitable for a landing; wind and high seas would make it impossible to launch landing craft from larger ships at sea, and low clouds would prevent aircraft finding their targets. The Allied troop convoys already at sea were forced to take shelter in bays and inlets on the south coast of Britain for the night.

It seemed possible that everything would have to be cancelled and the troops returned to their embarkation camps (which would be almost impossible, as the enormous movement of follow-up formations into them was already proceeding).[11] The next full moon period would be nearly a month away. At a vital meeting on 5 June, Eisenhower's chief meteorologist (Group Captain J.M. Stagg) forecast a brief improvement for 6 June. Commander of all land forces for the invasion General Bernard Montgomery and Eisenhower's Chief of Staff General Walter Bedell Smith wished to proceed with the invasion. Commander of the Allied Air Forces Air Chief Marshal Leigh Mallory was doubtful, but the Allied Naval supremo Admiral Bertram Ramsay believed that conditions would be marginally favorable. On the strength of Stagg's forecast, Eisenhower ordered the invasion to proceed. As a result, prevailing overcast skies limited Allied air support, and no serious damage could be done to the beach defences on Omaha and Juno.[12]

The Germans meanwhile took comfort from the existing poor conditions, which were worse over Northern France than over the English Channel itself, and believed no invasion would be possible for several days. Some troops stood down, and many senior officers were away for the weekend. Field Marshal Erwin Rommel took a few days' leave to celebrate his wife's birthday,[13] while dozens of division, regimental and battalion commanders were away from their posts conducting war games just prior to the invasion

Operation Neptune Edit

Warships provided supporting fire for the land forces. During Neptune, it was given a high importance, using ships from battleships to destroyers and landing craft. For example, the Canadians at Juno beach had fire support many times greater than they had had for the Dieppe Raid in 1942. The old battleships HMS Ramillies and Warspite and the monitor HMS Roberts were used to suppress shore batteries east of the Orne; cruisers targeted shore batteries at Ver-sur-Mer and Moulineaux; eleven destroyers for local fire support. In addition, there were modified landing-craft: eight "Landing Craft Gun", each with two 4.7-inch guns; four "Landing Craft Support" with automatic cannon; eight Landing Craft Tank (Rocket), each with a single salvo of 1,100 5-inch rockets; eight Landing Craft Assault (Hedgerow), each with twenty-four bombs intended to detonate beach mines prematurely. Twenty-four Landing Craft Tank carried Priest self-propelled howitzers, which also fired while they were on the run-in to the beach. Similar arrangements existed at other beaches.

Fire support went beyond the suppression of shore defences overlooking landing beaches and was also used to break up enemy concentrations as the troops moved inland. This was particularly noted in German reports: von Rundstedt reported that: ... The enemy had deployed very strong Naval forces off the shores of the bridgehead. These can be used as quickly mobile, constantly available artillery, at points where they are necessary as defence against our attacks or as support for enemy attacks. During the day their fire is skilfully directed by . . . plane observers, and by advanced ground fire spotters. Because of the high rapid-fire capacity of Naval guns they play an important part in the battle within their range. The movement of tanks by day, in open country, within the range of these naval guns is hardly possible.[32]

HMS Lawford , one of several Captain class frigates converted to act as a headquarters ship for the Normandy landings. Note the extended superstructure (to accommodate the Staff Officers) and additional smaller mainmast to support the extra aerials. On 8 June 1944, while operating off Juno Beach, she was hit by enemy fire during an air attack and sunk The only naval contact during D-Day occurred when four German torpedo boats reached the Eastern Task Force late in the afternoon and launched eighteen torpedoes, sinking the Norwegian destroyer HNoMS Svenner off Sword beach but missing the battleships HMS Warspite and Ramillies. After firing, the German vessels turned away and fled east into a smoke screen. Thanks to ULTRA, the Allies knew where the Germans' channel was through their own minefields. The only Allied losses to mines were the USS Corry off Utah; USS PC-1261, a 173-foot patrol craft; three LCTs; and two LCIs

British & Canadian LandingsEdit

The success of the amphibious landings depended on the establishment of a secure lodgement from which to expand the beachhead to allow the build up of a well-supplied force capable of breaking out. The amphibious forces were especially vulnerable to strong enemy counter-attacks before the build up of sufficient forces in the beachhead could be accomplished. To slow or eliminate the enemy's ability to organize and launch counter-attacks during this critical period, airborne operations were used to seize key objectives, such as bridges, road crossings, and terrain features, particularly on the eastern and western flanks of the landing areas. The airborne landings some distance behind the beaches were also intended to ease the egress of the amphibious forces off the beaches, and in some cases to neutralize German coastal defence batteries and more quickly expand the area of the beachhead. The US 82nd and 101st Airborne Divisions were assigned to objectives west of Utah Beach. The British 6th Airborne Division was assigned to similar objectives on the eastern flank. 530 Free French paratroopers, from the British Special Air Service Brigade, were assigned to objectives in Brittany from 5 June to August.[34][35] (Operations Dingson, Samwest, and Cooney). The Royal Air Force flew and supplied half of the aircraft deployed. Nearly half of the US gliders were the larger Airspeed Horsa, as they carried twice as much as the US equivalent. The RAF created a new command, the 2nd Tactical Air Force flying low level missions especially to support operations on the ground.

The first Allied action of D-Day was Operation Deadstick, a glider assault at 00:16 on the bridges over the Caen canal and the River Orne. These were the only crossings of the river and canal north of Caen around 7 kilometres (4.5 mi) from the coast, near Bénouville and Ranville. For the Germans, the crossing provided the only route for a flanking attack on the beaches from the east. For the Allies, the crossing was also vital for any attack on Caen from the east.

The tactical objectives of the British 6th Airborne Division were (a) to capture intact the bridges of the Bénouville-Ranville crossing, (b) to defend the crossing against the inevitable armoured counter-attacks, (c) to destroy German artillery at the Merville battery, which threatened Sword Beach, and (d) to destroy five bridges over the Dives River to further restrict movement of ground forces from the east.

Airborne troops, mostly paratroopers of the 3rd and 5th Parachute Brigades, including the 1st Canadian Parachute Battalion, began landing after midnight, 6 June and immediately encountered elements of the German 716th Infantry Division. At dawn, the Battle Group von Luck of the 21st Panzer Division counter-attacked from the south on both sides of the Orne River. By this time the paratroopers had established a defensive perimeter surrounding the bridgehead. Casualties were heavy on both sides, but the airborne troops held. Shortly after noon, they were reinforced by commandos of the 1st Special Service Brigade. By the end of D-Day, reinforced by Operation Mallard, the 6th Airborne had accomplished all of its objectives. For several days, both British and German forces took heavy casualties as they struggled for positions around the Orne bridgehead. For example, the German 346th Infantry Division broke through the eastern edge of the defensive line on 10 June. Finally, British paratroopers overwhelmed entrenched panzergrenadiers in the Battle of Breville on 12 June. The Germans did not seriously threaten the bridgehead again. 6th Airborne remained on the line until it was evacuated in early September.

American airborne landingsEdit

The US 82nd and 101st Airborne Divisions, numbering 13,000 paratroopers delivered by 12 troop carrier groups of the IX Troop Carrier Command, were less fortunate in completing their main objectives. To achieve surprise, the drops were routed to approach Normandy from the west. Numerous factors affected their performance, chief of which was the decision to make a massive parachute drop at night (a tactic not used again for the rest of the war). As a result, 45% of units were widely scattered and unable to rally. Efforts of the early wave of pathfinder teams to mark the landing zones were largely ineffective, and the Rebecca/Eureka transponding radar beacons used to guide in the waves of C-47 Skytrains to the drop zones were the main component of a flawed system. Three regiments of 101st Airborne paratroopers were dropped first, between 00:48 and 01:40, followed by the 82nd Airborne's drops between 01:51 and 02:42. Each operation involved approximately 400 C-47 aircraft. Two pre-dawn glider landings brought in anti-tank guns and support troops for each division. On the evening of D-Day two additional glider landings brought in two battalions of artillery and 24 howitzers to the 82nd Airborne. Additional glider operations on 7 June delivered the 325th Glider Infantry Regiment to the 82nd Airborne; two large supply parachute drops that date were ineffective. After 24 hours, only 2,500 men of the 101st and 2,000 of the 82nd were under the control of their divisions, approximating a third of the force dropped. The dispersal of the American airborne troops, however, had the effect of confusing the Germans and fragmenting their response. In addition, the Germans' defensive flooding, in the early stages, also helped to protect the Americans' southern flank. Paratroopers continued to roam and fight behind enemy lines for days. Many consolidated into small groups, rallied by NCOs or junior officers, and were usually a hodgepodge of men from different companies, battalions, regiments, or even divisions. The 82nd occupied the town of Sainte-Mère-Église early in the morning of 6 June, giving it the claim of the first town liberated in the invasion.

Operation OverloadEdit

Sword BeachEdit

The assault on Sword Beach began at about 03:00 with an aerial bombardment of the German coastal defences and artillery sites. The naval bombardment began a few hours later. At 07:30, the first units reached the beach. These were the DD tanks of 13th/18th Hussars followed closely by the infantry of 8th Brigade.

On Sword Beach, the regular British infantry came ashore with light casualties. They had advanced about eight kilometres (5 mi) by the end of the day but failed to take some of the deliberately ambitious targets set by Montgomery. In particular, Caen, a major objective, was still in German hands by the end of D-Day, and would remain so until mid-July (central urban area cleared 8–9 July, suburbs fully cleared by 20 July in Operation Atlantic), see Battle for Caen. 1st Special Service Brigade, under the command of Brigadier The Lord Lovat DSO, MC, went ashore in the second wave led by No. 4 Commando with the two French Troops first, as agreed amongst themselves. The 1st Special Service Brigade's landing is famous for having been led by Piper Bill Millin. The British and French members of No. 4 Commando had separate targets in Ouistreham: the French, a blockhouse and the Casino; the British two German batteries that overlooked the beach. The blockhouse proved too strong for the Commandos' PIAT (Projector Infantry Anti Tank) weapons, but the Casino was taken with the aid of a Centaur tank. The British Commandos achieved both battery objectives only to find the gun mounts empty and the guns removed. Leaving the mopping-up procedure to the infantry, the Commandos withdrew from Ouistreham to join the other units of their brigade (Nos.3, 6 and 45), moving inland to join-up with the 6th Airborne Division.

Juno BeachEdit

The Canadian forces that landed on Juno Beach faced two heavy batteries of 155 mm guns and nine medium batteries of 75 mm guns, as well as machine-gun nests, pillboxes, other concrete fortifications, and a seawall twice the height of the one at Omaha Beach. The first wave suffered 50% casualties, the second highest of the five D-Day beachheads. The use of armour was successful at Juno, in some instances actually landing ahead of the infantry as intended and helping to clear a path inland.

Despite the obstacles, the Canadians were off the beach within hours and beginning their advance inland. A single troop of four tanks managed to reach the final objective phase line, but hastily retreated, having outrun its infantry support. In particular, two fortified positions at the Douvres Radar Station remained in German hands (and would for several days until captured by British commandos), and no link had been established with Sword Beach.

By the end of D-Day, 30,000 Canadians had been successfully landed, and the 3rd Canadian Infantry Division had penetrated further into France than any other Allied force, despite having faced strong resistance at the water's edge and later counterattacks on the beachhead by elements of the German 21st and 12th SS Hitlerjugend (Hitler Youth) Panzer divisions on 7 and 8 June.

Gold BeachEdit

At Gold Beach, 25,000 men were landed, under the command of Lieutenant-General Miles Dempsey, Commander of the British 2nd Army. Casualties were also quite heavy; around 400, partly because bad weather delayed the swimming Sherman DD tanks, and also because the Germans had strongly fortified a village on the beach. However, the 50th (Northumbrian) Infantry Division overcame these difficulties and advanced almost to the outskirts of Bayeux by the end of the day. With the exception of the Canadians at Juno Beach, no division came closer to its objectives than the 50th. No. 47 (RM) Commando was the last British Commando unit to land and came ashore on Gold east of La Hamel. Their task was to proceed inland then turn right (west) and make a 16-kilometre (10 mi) march through enemy territory to attack the coastal harbour of Port en Bessin from the rear. This small port, on the British extreme right, was well sheltered in the chalk cliffs and significant in that it was to be a prime early harbour for supplies to be brought in, including fuel by underwater pipe from tankers moored offshore.

Omaha Beach Edit

Elements of the 1st Infantry Division and 29th Infantry Division (US) faced the recently formed German 352nd Infantry Division, a mixed group of Russian "volunteers" and teenagers stiffened with a cadre of eastern front veterans, unusual in the fact that it was one of the few German divisions remaining with a full complement of three regiments albeit at reduced strength; fifty percent of its officers had no combat experience. However, Allied intelligence was unaware until two weeks before the planned invasion that the 100 km stretch of beach originally allocated to be defended by the 716th Infantry Division (static) had been cut into two parts in March, with the 716th moving to the "Caen Zone", and the 352nd taking over the "Bayeux Zone", thus doubling the complement of defenders.[38] Omaha was also the most heavily fortified beach, with high bluffs defended by funneled mortars, machine guns, and artillery; the pre-landing aerial and naval bombardment of the bunkers proved to be ineffective. Difficulties in navigation caused the majority of landings to drift eastwards, missing their assigned sectors and the initial assault waves of tanks, infantry and engineers took heavy casualties. Of the 16 tanks that landed upon the shores of Omaha Beach only two survived the landing. The official record stated that "within 10 minutes of the ramps being lowered, [the leading] company had become inert, leaderless and almost incapable of action. Every officer and sergeant had been killed or wounded [...] It had become a struggle for survival and rescue". Only a few gaps were blown in the beach obstacles, resulting in problems for subsequent landings. The heavily defended draws, the only vehicular routes off the beach, could not be taken and two hours after the first assault the beach was closed for all but infantry landings. Commanders (including General Omar Bradley) considered abandoning the beachhead, but small units of infantry, often forming ad-hoc groups, supported by naval artillery and the surviving tanks, eventually infiltrated the coastal defences by scaling the bluffs between strongpoints. Further infantry landings were able to exploit the initial penetrations and by the end of the day, two isolated footholds had been established. American casualties at Omaha on D-Day numbered around 5,000 out of 50,000 men, most in the first few hours, while the Germans suffered 1,200 killed, wounded or missing. The tenuous beachhead was expanded over the following days, and the original D-Day objectives were accomplished by D+3.

Pointe du HocEdit

The massive concrete cliff-top gun emplacement at Pointe du Hoc was the target of the 2nd Ranger Battalion, commanded by James Earl Rudder. The task was to scale the 30 meter (100 ft) cliffs under the cover of night, approximately at 5:30, one hour prior to the landings with ropes and ladders, and then attack and destroy the German 15,5 cm Kanone 418(f) coastal defence guns, which were thought to command the Omaha and Utah landing areas. The infantry commanders did not know that the guns had been moved prior to the attack, they had to press farther inland to find them and eventually destroy them. However, the fortifications themselves were still vital targets as a single artillery forward observer based there could have called down accurate fire on the US beaches. The Rangers were eventually successful, and captured the fortifications. They then had to fight for two days to hold the location, losing more than 60% of their men. They subsequently regrouped and continued northeast to the rally point one mile from the gun emplacements on Pointe Du Hoc.

Utah BeachEdit

Landing craft approach the beach as smoke on the shore emanates from German positions Casualties on Utah Beach, the westernmost landing zone, were the lightest of any beach, with 197 out of the roughly 23,000 men that landed. The 4th Infantry Division troops landing at Utah Beach found themselves in the wrong positions because of a current that pushed their landing craft to the southeast. Instead of landing at Tare Green and Uncle Red sectors, they came ashore at Victor sector, relatively little German opposition was encountered. The 4th Infantry Division was able to press inland relatively easily over beach exits that had been seized from the inland side by the 502nd and 506th Parachute Infantry Regiments of the 101st Airborne Division. This was partially by accident, because their planned landing was further along the beach. (Brigadier General Theodore Roosevelt, Jr., the Assistant Commander of the 4th Division, upon discovering the landings were off course, became famous for saying "We will start the war from right here.") By early afternoon, the 4th Infantry Division had succeeded in linking up with elements of the 101st. American casualties were light, the troops were able to press inward much faster than expected, making it a near-complete success.

Aftermath Edit

Once the beachhead was established, the Mulberry Harbours were made operational around 9 June. One was constructed at Arromanches by British forces, the other at Omaha Beach by American forces. Severe storms on 19 June interrupted the landing of supplies and destroyed the Omaha harbour. The Arromanches harbour was able to supply around 9,000 tons of materiel daily until the end of August 1944, by which time the port of Cherbourg had been secured by the Allies.

Despite this, the German 21st Panzer division mounted a counterattack, between Sword and Juno beaches and succeeded in nearly reaching the channel. Stiff resistance by anti-tank gunners and fear of being cut off caused them to withdraw before the end of 6 June. According to some reports, the sighting of a wave of airborne troops flying over them was instrumental in the decision to retreat.

The Allied invasion plans had called for the capture of Carentan, St. Lô, Caen and Bayeux on the first day, with all the beaches linked except Utah and Sword (the last linked with paratroopers) and a front line 10 to 16 kilometres (6.2 to 9.9 mi) from the beaches; none of these had been achieved. Casualties had not been as heavy as some had feared (around 10,000 compared to the 20,000 Churchill had estimated) and the bridgeheads had withstood the expected counterattacks.
