The defeat in the Battle of Sicily was a great blow and a disgrace to Montgomery.

So as soon as he retreated to Tunisia, he turned on the remnants of his British 8th Army Group; Start training more rigorously.

He ordered his troops to train in all kinds of climates, whether it was wind and rain, violent storms, ice and snow, even hot weather, and dark nights, they had to carry out arduous and all-out actual combat training.

His aim was to make the remnants of his own units more effective than the SS units that had defeated them, and even all the German units.

Moreover, he will also seriously simulate the special combat situations that may occur on the real battlefield, such as how to deal with the German attack and how to counterattack in the case of the sudden appearance of a large number of new weapons and equipment like Sicily, or the loss of air supremacy.

Moreover, these actual combat simulation training was carried out continuously and completed in 25 hours.

Of course, sometimes such brutal combat training is carried out at a high frequency for several days and nights, and even those recruits who have just been added to the 8th Army Group have to carry out such arduous training together.

While the soldiers were conducting these trainings, Montgomery was always standing near them, observing the combat weaknesses of the British troops, finding out all these weaknesses, and then using the strengths of the British army to replace these weaknesses, and even finding ways to overcome these fatal combat weaknesses.

Because for Montgomery, the current German army and Hitler have been regarded by him as cunning foxes, and they should not be taken lightly.

Therefore, even if in the midst of harsh actual combat training, all the officers and soldiers who were unable to withstand overwork training and training in a difficult combat environment were replaced, and he had to train a group of troops that could really defeat the German SS.

Because at this moment Montgomery had already listed the German SS, and even the German troops that fought more fiercely, as the object to be defeated.

He was to be ashamed of his defeat in the Battle of Sicily.

Of course, in addition to the fact that he trained his troops so harshly after the war, Patton did not lose to him at all.

Because Patton also dispatched the navy, land and air force, as well as armored troops, and artillery units to conduct more brutal combat training.

Because for Patton, he also wants to make his troops strong as soon as possible, catch up with the German troops, and then in the next battle, beat the German army to pieces, so that he can avenge the dead American soldiers, and rebuild the glory for his lost reputation.

Of course, whether it's him or Barton, when they're doing these practical combat training that challenges the limits of human beings; It was also the construction of a large number of comfortable barracks for those soldiers, and the provision of a large number of delicious and nutritious food, as well as nutrients.

At the same time, all kinds of sanitary conditions, medical systems, bonus systems, military supplies and other logistical supplies, and things are also to achieve the effect of grace and power.

Because Montgomery and Patton's ultimate goal was to fully unite their troops through these brutal combat training and the treatment of soldiers who bought people's hearts, and to optimize the combat effectiveness of their troops to the maximum, defeat the German army, and become an invincible elite division.

At the same time, they also hope that their troops, no matter any disadvantage, or any big victory, can maintain a strong will to fight, not impatient, and optimistic.

In addition to this, Montgomery also had Churchill's consent, and in Britain itself, a great deal of defense work began to be built; and a large number of counterattack reserves in case the Germans launched a surprise attack on the British mainland, or a landing operation.

Because in this Sicilian campaign, the high-ranking officers of Britain and the United States and other allied countries saw the German aircraft carrier fleet and submarine forces; As well as the awesomeness of the aviation forces, as well as the long-range offensive of the German army, it has become a fire.

That's why Churchill so painfully agreed to Montgomery's home defense strategy and to train their British troops to the death.

Of course, even President Roosevelt and Eisenhower, as well as Marshall, unanimously agreed to Patton's brutal combat training of the army, navy and air force.

In addition, the United States also began to build fortifications for the homeland defense strategy, because it was worried that the Japanese army would carry out a landing operation on the homeland with the German army, which had an aircraft carrier fleet and an ultra-long-range submarine force.

In addition, this time, whether it was the intelligence department of the British army, the US military, or the intelligence department of the Soviet army and other countries, they all sent all the elite spies like crazy, trying to enter Germany by all means, or the German troops in the German-occupied areas, to investigate the information of the new weapons and equipment that the Germans had sunk a large number of US aircraft carriers within an hour.

Of course, they are also willing to loot the information of other new German weapons and equipment at any cost.

At this time, the commander of the U.S. Army Air Corps, Henry Brown, was in charge of the U.S. Army Air Corps. General H. Hap Arnold, General Ulf and General H. Brigadier General G. Köllner, along with the famous aviator Charles Lindenberg, and General Arnold, were accompanying Hopkins, President Roosevelt, and Admiral Marshall on a tour of the production plant of the B-29 bomber group.

These are Bell's new facilities in Marietta, Georgia; North American Aircraft's new facility in Kansas City, Missouri; General Motors' Fisher Brothers division has a new plant in Cleveland, Ohio, and Boeing's Wichita, Kansas, among other plants.

Behind President Roosevelt's group of high-ranking American figures, there were also Boeing, Consaureid, Douglas, and Lockheed's entourage.

In addition to these people, there are also people from Chrysler, Hudson, Goodyear, Briggs, Murray, Cessna and other companies have also sent senior executives over, because these companies are aircraft parts companies designated by the U.S. government to produce the main fuselage components of the B-29.

Eventually, senior managers from Bendix, General Electric, Sperry, and Westinghouse, who were vying for contracts for remote-controlled turret systems, also came to the scene and followed President Roosevelt on their inspections.

Because after the defeat in the Battle of Sicily, General Arnold and General Ulf after obtaining the consent of President Roosevelt; A specialized process group of B-29 bombers and P-51 Mustang fighters was immediately established.

The function of this group is to get the aircraft manufacturers designated by the US government in one to two months; In a hurry, we went all out to work overtime to produce the latest B-29 bomber fleet equipped with very sophisticated electronic equipment and equipped with the AN/APN-4 Roland long-range navigation system of Figurt.

At the same time, when rushing to produce the production process, the technical masters, engineers, technical directors, and scientists of the major production lines, experimental workshops, assembly lines, and R&D departments of the U.S. military are constantly raising all kinds of incurable diseases on the drawings and objects of the B-29, as well as solving the problems and loopholes of each component of the B-29, and quickly cutting through the mess.

As for the general problems and calculations, as well as the experiments, it is left to the engineers in the design room, the process room, and the central laboratory to deal with, or to find out the problems and shortcomings that have been missed.

Of course, the pilots who fly these new bomber groups and fighter groups are constantly recruiting, supplementing, and expanding the US air force, and conducting brutal training to make these pilots more familiar with the combat performance of these aircraft.

At the same time, the FJ-1 "Nemesis", which was originally supposed to be developed in December 1944, tested in September 1946, and officially delivered to the US Navy in November 1947, was officially developed and produced in advance on July 23, 1943.

At the same time, President Roosevelt hoped to be able to carry out a test flight of this jet aircraft on an aircraft carrier within three months.

In addition to the FJ-1 "Nemesis" jet, which has been included in the emergency development and production process by President Roosevelt; In addition, the F9F "Leopard" carrier-based fighter developed by the Grumman Aircraft Company, which should have been put into service in 1948, was also highly valued by President Roosevelt, and a large amount of money was invested in research in advance.

President Roosevelt's order to the major research and development institutions was to develop this jet aircraft at all costs and before January 30, 1944.

And President Roosevelt's confidence is because in the Battle of Sicily, as well as the battles in the British Seas, and the battles on the Eastern Front, they were very fortunate to obtain a lot of German downed F8B fighters, and German Me262 jet fighters, as well as Ar-234 jet bombers, as well as the wreckage of Ta-152 fighters, or relatively complete fuselage for the US naval forces, and army units obtained on the battlefield and transported back to the secret military bases of Britain, the United States, the Soviet Union and other countries. Conduct in-depth decomposition studies.
