Normandy landings
The decision to invade Normandy in 1943 began a complex web of military deception known as Operation Bodyguard. Allied planners needed to convince Adolf Hitler that the main attack would strike at Pas-de-Calais instead of the actual target. This strategy relied on creating a fictitious First United States Army Group under Lieutenant General George S. Patton, supposedly stationed in Kent and Sussex. Genuine radio messages from the 21st Army Group were routed through landlines to Kent before being broadcast to German listeners. The goal was to make the Germans believe an invasion force existed where none actually did.
Adolf Hitler placed Field Marshal Erwin Rommel in command of German forces along the Atlantic Wall. Meanwhile, US President Franklin D. Roosevelt appointed Major General Dwight D. Eisenhower to lead all Allied forces. The Allies considered four potential landing sites: Brittany, the Cotentin Peninsula, Normandy, and Pas-de-Calais. They rejected Brittany and Cotentin because these peninsulas could be cut off by the Germans at narrow isthmuses. Pas-de-Calais remained heavily fortified because it was the closest point to Britain.
Normandy offered a broad front for simultaneous threats against Cherbourg and Paris. The lack of port facilities there became a major logistical challenge. Planners overcame this obstacle by developing artificial Mulberry harbours. Modified tanks nicknamed Hobart's Funnies handled mine clearing and mobile bridging tasks. Initial planning started with three divisions but expanded to five after Eisenhower and Montgomery insisted on a wider front. This expansion required extra landing craft and pushed the invasion date from May into June.
Group Captain James Stagg of the Royal Air Force met Eisenhower on the evening of the 4th of June 1944. He predicted that weather conditions would improve enough for the invasion to proceed on the 6th of June. High winds and heavy seas had made launching landing craft impossible on the 5th of June. Low cloud cover also prevented aircraft from finding their targets. A full moon was desirable for illumination while high tides helped expose beach obstacles.
The Allies needed specific tidal conditions that occurred only on a few days each month. Postponing the operation beyond the 6th of June meant waiting two weeks until 18 to the 20th of June. Such a delay would have forced planners to recall men and ships already positioned in the English Channel. It would also increase the chance that German intelligence detected the entire plan. Eisenhower decided to launch the attack despite the risks.
A major storm battered the Normandy coast from 19 to the 22nd of June, making landings impossible during those later dates. Allied control of the Atlantic gave them better weather information than the Germans. The Luftwaffe meteorological centre in Paris predicted two weeks of stormy weather. Many Wehrmacht commanders left their posts to attend war games in Rennes. Field Marshal Erwin Rommel returned to Germany for his wife's birthday.
Paratroopers of the 82nd and 101st Airborne Divisions numbered over 13,000 men delivered by Douglas C-47 Skytrains. Navigation proved difficult because thick cloud cover obscured drop zones. Only one of five paratrooper drop zones received accurate radar signals and Aldis lamps. Paratroops from the 101st Airborne began dropping around 01:30 on the 6th of June 1944. They controlled causeways behind Utah Beach while destroying road and rail bridges over the Douve River.
Many planes flew so low they came under fire from flak and machine guns. Some paratroopers drowned in flooded fields or died when parachutes failed to open. Gathering into fighting units became hard due to shortages of radios and dense bocage terrain. Units did not reach targets until afternoon, sometimes after causeways had already been cleared by infantry moving up from beaches. By 02:30 troops of the 82nd Airborne began arriving with objectives to capture two bridges over the River Merderet.
The British 6th Airborne Division captured intact bridges over the Caen Canal and River Orne at 00:16. These structures were renamed Pegasus Bridge and Horsa Bridge. Lieutenant Colonel Terence Otway led a force of only 160 men against an enemy battery at Merville. Allied forces disabled the guns using plastic explosives despite suffering 75 casualties. The emplacement contained 75 mm guns rather than expected heavy coastal artillery.
Utah Beach saw members of the 8th Infantry Regiment land at 06:30 on the 6th of June 1944. Strong currents pushed landing craft south to a site with fewer German defenses. Brigadier General Theodore Roosevelt Jr. ordered further landings re-routed to this new location. The 4th Infantry Division landed 21,000 troops with only 197 casualties. They disabled main strongpoints by noon while skirmishing throughout the day with elements of the 919th Grenadier Regiment.
Omaha Beach presented the heaviest resistance with the 352nd Infantry Division facing American forces. Many landing craft ran aground on sandbars forcing men to wade 50 to 100 meters in water up to their necks. DD tanks of two companies flooded and sank before reaching shore. Casualties reached around 2,000 as men faced fire from cliffs above. A beachmaster called a halt to vehicle landings at 08:30 until destroyers provided fire support.
Gold Beach required British troops to clear heavily fortified houses along the shore. Company Sergeant Major Stanley Hollis received the only Victoria Cross awarded on D-Day for actions including attacking pillboxes at Mont Fleury. Juno Beach saw Canadian soldiers face machine gun emplacements covering roads inland. Bayeux remained in German hands because of stiff resistance from the 352nd Infantry Division. Sword Beach became congested quickly due to windy conditions and rapid tide changes.
Hitler ordered construction of fortifications along the Atlantic coast from Spain to Norway but shortages prevented completion. Rommel reported that construction was only 18 percent complete in some areas shortly before D-Day. The Pas-de-Calais region received most defenses while Normandy had fewer strongpoints. Rommel placed wooden stakes and mines on beaches to delay landing craft approach.
Field Marshal Gerd von Rundstedt disagreed with Rommel about tank deployment strategies. They believed large-scale movement of tanks would be impossible once invasion began due to Allied air supremacy. Hitler made the final decision leaving three Panzer divisions under Geyr's command. He took personal control of four other divisions as strategic reserves requiring his direct orders. This indecisive command structure hampered German response efforts.
The Luftwaffe could muster only 815 aircraft over Normandy compared to 9,543 Allied planes. Many German units were understrength with conscripts from Russia and Mongolia lacking motorized transport. Combat losses meant soldiers averaged six years older than their Allied counterparts. The 7th Army received notification of parachute drops at 01:20 but Rundstedt did not initially believe a major invasion was underway.
German orders required French civilians other than those essential to war effort to leave potential combat zones in Normandy. Civilian casualties on D-Day and D+1 are estimated at 3,000 people. The Allied victory stemmed from factors including partially finished Atlantic Wall defenses and successful deception operations. Infrastructure for transport in France was severely disrupted by Allied bombers and French Resistance sabotage efforts.
At Omaha Beach parts of the Mulberry harbour remain visible today alongside some beach obstacles. A memorial to the US National Guard sits at location of former German strongpoint. Pointe du Hoc remains little changed from 1944 with terrain covered in bomb craters and concrete bunkers still standing. The Normandy American Cemetery and Memorial is nearby in Colleville-sur-Mer.
A museum about Utah landings exists at Sainte-Marie-du-Mont while another dedicated to US airmen stands at Sainte-Mère-Église. Sections of Mulberry Harbour B still sit in sea at Arromanches. The Juno Beach Centre opened in 2003 funded by Canadian governments and France. The British Normandy Memorial above Gold Beach designed by architect Liam O'Connor opened in 2021.
