Bivan's strategic deception can be said to be admirable, but if it fails to do a good job of secrecy and leaks the truth, then not only will the well-planned strategic deception be useless, but it will also bring disaster to the landing, so Britain has adopted unprecedented secrecy measures, codenamed "Diehard Procedure".

First of all, in order to prevent Germany and Italy from obtaining information from Ireland, Britain and the United States forced Ireland to close the German and Italian embassies in Ireland and confiscate their radio equipment. On 9 February 1941, Britain severed all people-to-people relations with Ireland. On March 17, it further announced a blockade of Ireland and intercepted all aircraft and ships leaving Ireland without permission.

Second, in order to prevent diplomats in the UK from obtaining information, the UK announced on April 17 that it would temporarily revoke diplomatic privileges and prohibit diplomats from travelling in and out of the UK. prohibition of the use of diplomatic mail; Diplomatic missions are prohibited from using radio stations to communicate with their countries, and in case of emergency, they can only use radio stations and operators provided by the United Kingdom; Diplomatic embassies of various countries are on full alert.

Third, strict news censorship is imposed on non-governmental news reports, and all reports must go through multiple checks before they can be published. Journalists were forbidden to send newspapers abroad, and newspapers and magazines were forbidden to be exported, in order to prevent Germany from obtaining information from them. From 25 May, all letters sent from the UK have been deferred. Restrict the entry and exit of citizens into and out of the UK except for essential persons.

Secrecy was also unprecedented, with 1 April declaring 10 miles off the southern coast of England where the landing force had assembled a military exclusion zone, and from 6 April the troops were on leave, and all official correspondence and telephone calls of military and civil servants were censored. US military personnel are forbidden to use transatlantic telephones and telegraphs to communicate with the US mainland without authorization.

From 28 May, all troops participating in the initial landing were not allowed to leave the barbed wire fence and inspected by the military police. About the landing plan. Always limited to carefully selected officers. Seven days before D-Day (i.e., the code name of the landing day), the landing date and plan are issued to the divisional commander. Three days before Day D, landing zone maps, charts, and other enemy information were distributed to battalion commanders. Two days before D, combat orders were issued to all units. At the same time, 2,000 intelligence personnel closely monitored and inspected the officers and men of the units participating in the battle.

Despite such unprecedented secrecy measures, leaks still occurred from time to time, but thanks to timely remediation, the truth was not learned by the German army.

On March 22, 1941, the staff of the Chicago Post Office in the United States opened a military parcel containing a landing operation plan without permission, and the personnel concerned were immediately examined and monitored by the Federal Bureau of Investigation, and it was finally found that it was only an accident.

April 18, 1941. U.S. Army Major General Henry? At a reception in London, England, Miller claimed that the Allies would attack France in early June. He was immediately relieved of his duties. The rank was demoted to lieutenant colonel and repatriated.

On May 28, 1941, twelve top-secret documents on the landing operation were blown into the street by the wind from the street windows of the British General Staff and scattered onto the road. Everyone in the General Staff at this time. From high-ranking officers to low-ranking clerks. It's like a great enemy. Rush out in search of the papers scattered across the street. But only eleven copies were recovered, just when everyone was anxious. A passer-by handed the twelfth document to the sentry on duty, and it was a false alarm.

So, how effective were the deception and secrecy measures of the Allies? The Allies deciphered the German code through "super-secret" and kept a close eye on the German reaction.

There are two kinds of codes in Limer's headquarters, one is the Engel code common to the German army, and the other is the original code, which the Allies have deciphered is the Engel code, and from the deciphered intelligence analysis, the German commander on the Western Front, Limer, the "villain" who had attacked the British home fleet, has been deceived, because at least seven German infantry divisions and three armored divisions are moving towards the Calais area. In fact, the Allies did not know at all, these troops were also fake, only the supplementary training regiments of those units were in the Far East, and the main forces of the division did not move at all, but only kept radio silence.

At this time, an accidental incident occurred, the Germans found the bodies of two American officers on the Omaha beachhead where the Allied troops landed, and carried with them all the combat plans of the US 5th Army and the 7th Army in the landing that they had not had time to destroy.

Limer's principle was to convince the Allies as much as possible that they had deceived themselves, that the Allied landing in Normandy was only a feint, and that the real landing was Calais.

Subsequently, the Chief of the General Staff of the US Army, Admiral Marshall, rushed to London and closely followed the movements of the German army together with the personnel of the Supreme Command and the London Supervision Office. Discussions were underway about bombing all bridges over the Seine, including those in the city of Paris, in order to stop German reinforcements. At midnight, the confidential secretary sent a message that the "super secret" had just received:

Limer had ordered the 15th Army to return to Calais, and the Germans in other parts of Western Europe were rushing to reinforce Calais. -- Everyone was relieved that, although the fighting in Normandy was still raging, everyone knew that the landing was in full swing.

The most surprising was Bevan, who never imagined that the "Guardian Project" would be so successful. Chief of the General Staff of the British Army, Allen? Marshal Brooke said, "Since Li Mo is such a big fool, how could we use such a long time and so much energy to defeat him? Then, British Prime Minister Winston Churchill and the head of British intelligence Menzies came to the High Command and spoke highly of the organization and implementation of the "Guardian Project": in the long history of British intelligence, this is the pinnacle!

But for Li Mo, a traverser, they are just clown-like performances, and they don't even know what to do, who is a fool will soon find out.

The assault echelon of the 82nd Airborne Division of the US Army is composed of the 505th, 507th, and 508th Paratrooper Regiments and reinforced detachments, with a total of 6,800 people, commanded by the division commander, Major General Ridgway, and carrying 369 transport planes, planning to be airborne on the west bank of the Mettler River west of St. Manygris, with the task of capturing St. Manygris, controlling the bridges and ferries of the Mettler River from Rafiel to Schiff Dubon, and ensuring the passage of the US 7th Army through the Mettler River.

The 505th Regiment was led by William? Colonel Ekman commanded the plan to land on the east bank of the Mettler River and capture Rafiel, Novel Opland, and Saint-Man-Ygris with 3 paratrooper battalions. The 1st Battalion was defeated by the Germans on the way to Rafael, and the battalion commander and acting battalion commander were killed one after another, and failed to complete the scheduled task of occupying Rafael.
