It is about the most legendary Dunkirk retreat in the history of World War II. The British and French allied forces were trapped on a narrow beach only 50 kilometers wide, and the British navy commander sent a telegram back to London in despair. In this dark moment of despair, 400,000 British and French troops ushered in a turning point, and finally they miraculously sent 300,000 people back to Britain. Only about 40 thousand French troops were captured by the Germans because they were behind the scenes.

With regard to this miraculous retreat, it is recognized that the savior of the British and French allied forces should be Hitler. Without Hitler's "stop moving" order, perhaps the famous German commander guderian would have commanded the tanks to fire in Dunkirk, but Hitler chose to follow Marshal Lundstadt's advice at this critical moment.

Moreover, rundstedt's suggestion is not unreasonable: the German army is advancing too fast, and it is difficult for the logistics troops to keep up with the supply. The two wings of the troops are easily attacked by the British and French Coalition forces in France and are caught between Scylla and Charybdis. After it has been confirmed that the British and French allied forces have surrounded the beaches of Dunkirk, it is a safe decision to take a slow and steady strategy. Hitler is more willing to give Air Force Marshal Goering a chance to show himself, and it is reasonable to say that air force bombing is indeed easier to annihilate the British and French allied forces in Dunkirk than the army.

However, the bad weather and the change of the weather made the air force fight against it. Coupled with the obstruction of the British air force, the army finally played an active role, and the two-day renovation of the German army also gave the British and French Coalition forces a valuable opportunity to retreat. They seized the opportunity to build defensive facilities and laid the foundation for the retreat in the next few days, which led to the miraculous Dunkirk retreat.
