As for the commander of the landing ground forces, it is well known that the Allied generals who can take on this post are either Lieutenant General Patton of the United States Army or Lieutenant General Montgomery of the British Army. General Beavan made plans to appoint Patton as commander of Army Group One, and on 26 April, Patton arrived in the south-east of England to inspect troops, meet with local officials, and visit celebrities.

His whereabouts were constantly reported in the press, and Patton spoke at the opening of a club: "After the war, Britain, the United States, and the Soviet Union will rule the world...... but when the newspaper published it, the Soviet Union was missing, causing a diplomatic storm.

It was puzzling that it was the eve of the landing, and the British press censorship was so strict that it was impossible for such an omission to make a speech that would affect the unity of the allies. The only explanation is that this was an elaborate hoax, just to reinforce the impression of Patton's presence in the southeast of England, so that the Germans thought that Patton, as commander of the landing force, would appear frequently in the southeast of England, which naturally meant that the landing would be in Calais.

The real landing force commander Montgomery was at the headquarters in Portsmouth to plan and study the battle plan, and Bivan also selected James, an army lieutenant who looked like Montgomery, to live by Montgomery's side for several months, to learn in detail about Montgomery's likes and dislikes, habits, and other details of life in all aspects of clothing, food, housing, and transportation, and then disguised himself as Montgomery to visit Gibraltar and Cairo, creating the false impression that Montgomery was not in Britain.

This led the Germans to deduce that Montgomery would not have been the commander of the landing at this time when he was not in England, and the "Mercury Plan" made the German High Command know that it was in the southeast of England through deception and camouflage in radio communications, barracks, troops, commanders, and so on. The Allies had assembled about 40 divisions to form the First Army Group, commanded by Patton, and the main direction of attack for the landing must have been Calais.

"Project Glimmer": electronic jamming and electronic deception carried out by the air forces of the allies. In accordance with the special instructions of the Supreme Command, the large radio interception and decipherment base set up by the German troops in The Hague, the Netherlands, was first violently bombed, completely destroying it and eliminating the threat to Allied radio communications.

Secondly, in the large-scale air raid on the German radar stations, the nine German radar stations north of the Seine were deliberately not bombed, so that the Germans could use these radar stations to detect the false fleet sent by the Allies before the landing, which sailed to Calais three hours before the landing, consisting of 18 small boats, each towing a raft. A large balloon with a diameter of up to 29 feet is installed on the top. Radar transmitters are installed in the balloons, which emit a radar signal equivalent to that of a Vendon-class landing ship, and dozens of planes fly over the fleet throwing tin chaff.

These measures were reflected on the screens of the German radar stations as a large landing flotilla heading for Calais under the cover of a large number of aircraft. In order to further confuse the German army, the Air Force made a special provision in the combat operations before the campaign: Whenever one reconnaissance plane was sent to Normandy or one ton of bombs was dropped. Be sure to send 2 reconnaissance planes or drop 2 tons of bombs to Calais.

The use of double agents is also an important part of Project Guardian. Thanks to the excellent work of the British counterintelligence services. Soon after the start of the war, a number of German spy groups in Britain were uncovered. and segregated German expatriates and purged a number of German spies in Britain.

Although German intelligence agencies continued to send agents to infiltrate Britain, a British counterintelligence agency was more efficient. Second, Britain's currency, weights and measures were completely different from those of continental Europe, making it easy for spies entering Britain to be detected, so Germany was unable to carry out intelligence work in Britain.

The British set up a special "Double Cross Committee" to turn arrested German spies into double agents in British service. After a long period of patient and meticulous training, he finally had four double agents who were trusted by German intelligence: "Garbo", "Jumbo", "Tricycle" and "Brewster".

Among them, the most trusted and influential in Germany is "Jiabao", "Jiabao" is a Spaniard, and his real name is Juan? Pujol? Garcia, who twice asked to join the British intelligence service, was denied. In January 1941, he defected to the German intelligence agencies and was ordered to infiltrate Britain through Portugal, but after he arrived in Portugal, he lied that he had entered Britain, and according to some newspapers and magazines published in Britain, he fabricated some information with his talent for fabricating information, and most of it was correct, so he was deeply respected and trusted by Germany.

It was not until February 1941 that Britain discovered that the Luftwaffe Navy and Air Force had launched a large-scale interception of an allied convoy bound for Malta, but there was no such fleet.

With the assistance of the "Double Cross Committee," a steady stream of carefully planned true and false information was sent to Germany, thus establishing the status of an ace agent in the German intelligence organs, and receiving the task of identifying the First Army Group [that is, the fictitious troops of the "Mercury Plan"), and taking the opportunity to report the strength of the First Army Group and other information in a grand manner.

"Treasure" is a French woman of Russian descent, Lily? It was she who gave a detailed report on the situation of the First Army Group and won the trust of the German intelligence services, and the German intelligence agencies also specifically asked her to go to Spain and provide her with a radio station for direct contact, which is extremely rare among the German intelligence services, and the degree to which she was valued can be seen.

"Brutus" is a former Polish Air Force officer, in the summer of 1940 in France organized underground resistance, arrested in November 1940, the German spy agency threatened him with the lives of the remaining 64 members of his group to serve Germany, came to Britain through Spain, and then surrendered to the British intelligence service, and then with the cooperation of the British intelligence agency, began to send reports to Germany outside London. A total of 123 pieces of information were sent to Germany from January to June 1941, almost all of which were confirmed by German intelligence to be accurate and deeply believed by the German army.

The British also organized an unusually cunning, even cruel and despicable operation in the "Guardian Project". In July 1941, the resistance group codenamed "Boom" in northern France was subordinate to the British Special Operations Service. Derigou's whistleblowing was uncovered by the German Gestapo, including the head Francis? Dozens of members of the resistance, including Suthir, were arrested.

The telegraph operator of the "Boom" cell, who was coerced by the Gestapo, continued to maintain contact with the British headquarters, because the telegraph operator's fingering was like a person's handwriting, which was difficult to counterfeit. The operator took the opportunity to report to the headquarters in accordance with the pre-stipulated non-issuance of a security code, and the so-called security code is to deliberately misspell or repeat a certain word in a certain line specified in the regulations, and if the word is not misspelled or repeated in the agreed place, it means that the radio station has been controlled by Germany.
