Hitler's Rest: D-Day Sleep Strategy

On June 6, 1944, the Allied forces launched an invasion of Normandy, France, as part of World War II. This operation, known as D-Day, was a pivotal moment in the war. However, when the invasion began, Adolf Hitler, the leader of Germany, was asleep. This unexpected detail raises questions about Hitler's role in the defense of Normandy and the impact of his sleeping habits on the course of history. It also highlights the complexities of military decision-making and the human factors that can influence the outcome of significant events.

Hitler's sleeping habits

Adolf Hitler had peculiar sleeping habits for a governing head of state. He was a notorious insomniac and would often stay awake late into the night, either working or watching films, and would not go to sleep until very late. Consequently, he was unaccustomed to waking up early and often slept until noon or later. On one occasion, he slept until 2 pm and stayed awake until midnight, eating cake and watching movies.

Hitler's daily routine involved getting up at about 10 am, seeing his barber, and then going for a walk. He would then have breakfast between 11 am and 11.30 am, usually consisting of coffee, bread, and marmalade. In the afternoon, he would receive visitors, including his doctor, artists, and other personalities. He would work until 10 pm, dine between 1 and 1.30 am, and sleep as late as 4 am.

On the day of the D-Day invasion of Normandy in June 1944, Hitler went to bed at around 3 am after watching a film with Joseph Goebbels and Eva Braun. He was not woken up when the first unconfirmed news of the invasion began to circulate at around 5 am, and his aides hesitated to wake him with what they believed might be mistaken information. By the time Albert Speer arrived at around 10 am, Hitler had still not been awakened, and it was only between 8.15 and 9.30 am that the initial skepticism at the Supreme Command of the Wehrmacht was dispelled. It is likely that Hitler was awakened as soon as the intelligence reports were confirmed.

Hitler's unusual sleeping habits had consequences for his decision-making during World War II. On D-Day, for example, two crucial Panzer divisions under his exclusive control were unusable because they could not be deployed without his express order.

Confusion among the Nazis

The Nazis' confusion on D-Day can be attributed to several factors, including Hitler's sleeping habits, the effectiveness of the Allied deception campaign, and the chain of command within the German military.

Hitler's unusual sleeping habits are well-documented. He often stayed awake late into the night, watching films or working on his construction plans, and consequently slept in until noon or later. On the eve of D-Day, Hitler retired around 3 a.m., and his subordinates had strict orders not to wake him for any reason. As a result, he slept through the initial hours of the invasion.

The Allies' deception campaign, codenamed Operation Fortitude, also played a significant role in the Nazis' confusion. Through the use of double agents, fake radio transmissions, dummy tanks, and aircraft, and other elaborate ruses, the Allies successfully convinced the Nazis that the invasion would take place at Pas-de-Calais, the closest point to Great Britain across the English Channel. This deception was so effective that even after the invasion of Normandy began, the Nazis still believed it to be a diversionary tactic, with the main attack yet to come at Pas-de-Calais.

Additionally, the chain of command within the German military contributed to the confusion. Hitler's insistence on controlling every aspect of his war machine meant that certain decisions, particularly those regarding the deployment of Panzer divisions, could only be made by him. This led to delays in responding to the invasion, as Hitler's approval was needed before certain units could be mobilised.

The absence of key German commanders on D-Day further exacerbated the situation. Field Marshal Erwin Rommel, who was in charge of defending the Normandy region, was visiting his wife in Germany, and many other senior commanders were not at their posts due to the stormy weather. This meant that there was a lack of clear leadership and coordination in the German response to the invasion.

In summary, the combination of Hitler's sleeping habits, the successful Allied deception campaign, and the complexities of the German chain of command all contributed to the confusion among the Nazis during the D-Day invasion. The delayed response allowed the Allies to gain a foothold and ultimately achieve victory in Europe.

The delayed German response

The German high command's initial confusion about the true nature of the invasion also contributed to the delay. Influenced by German intelligence reports, Hitler had previously spoken about the invasion beginning with a decoy attack, and the Allies' deception tactics, such as dropping dummy parachutists, added to the uncertainty. The German leadership hesitated to wake Hitler with unconfirmed information.

The delay in waking Hitler had significant consequences. Two crucial Panzer divisions under his exclusive control were left idle, and the Allies were able to gain a foothold during this time. When Hitler finally woke up around noon, he was informed of the invasion but seemed relieved, believing that the Allied troops were inferior and that the invasion played into his hands.

Hitler's morning lie-in, combined with the rigidity of the German command system, significantly weakened the German response to the oncoming Allied forces. The top German commander in the west, Field Marshal Gerd von Rundstedt, had requested the release of two reserve Panzer divisions held in Paris, but his request was initially denied by the overall military headquarters in Germany due to uncertainty about the invasion. By the time Hitler approved the release of the divisions at lunchtime, it was too late to make a difference. They had to wait out the daylight hours to avoid being destroyed by Allied aircraft, which controlled the French skies.

The Allies' advantage

The Allies had also gone to great lengths to deceive the Germans about the invasion, including running Operation Fortitude, which featured fake radio transmissions, and dropping dummy paratroopers from aircraft near Normandy. This added to the Germans' confusion about the location of the landing and the authenticity of the attack.

Hitler was finally woken at noon, by which time the Allies had gained a significant advantage. Two crucial Panzer divisions under Hitler's exclusive control were unable to be deployed, and the German response was slow and disorganised.

The combination of Hitler's sleeping habits, effective Allied deception tactics, and the flexibility of the Allied command structure thus contributed to the Allies' advantage on D-Day.

The role of the Panzer divisions

The Panzer divisions were instrumental in stifling the British hopes of reaching Caen during their initial attack. The 21st Panzer Division, under the command of Feldmarschall Erwin Rommel, was the only German armoured division poised to launch any counterattack during the Allied landings on D-Day. Rommel's determination to defeat the Allies on the beaches meant major improvements were needed to be carried out on his first line of defence – the much-vaunted 'Atlantic Wall'. This was the chain of coastal fortifications that stretched from western France to Norway.

The 21st Panzer Division was originally one of the two armoured divisions that made up the Deutsches Afrikakorps in the North African campaigns of 1941-1943. The division was reconstituted in June 1943 in Normandy, where it remained on garrison duty until the Allied invasion of June 6, 1944. The division was the only Panzer division to engage the Allies on the first day.

The 21st Panzer Division was grouped with two other Panzer divisions, 12SS and Panzer Lehr, under the command of Sepp Dietrich, which were to push northwest to retake Bayeux. However, this plan was abandoned when the divisional staff were killed in an air raid. The division continued to fight as part of the front throughout June and July.

The disposition of German armour meant only the 21st Panzer Division was immediately available for a counterattack. Some of its units had already been engaged by British airborne forces, but it was not until mid-afternoon on D-Day that the division finally advanced against the British north of Caen. The German assault was beaten back by British tanks and artillery. Some panzers actually reached the coast but then had to withdraw. They lost 70 out of 124 tanks.

The 21st Panzer Division continued to operate on the front through the remainder of June and into July. It was all but destroyed in the Falaise Pocket during the closing stages of the Battle of Normandy.
