On June 4, 1940 (April 29 of the lunar calendar), the British and French army's retreat from Dunkirk ended. A column of British destroyers full of British and French officers and men retreated to England on May 24, 1940. Nearly 400,000 British, French and Belgian troops in northern France and Belgium were forced to retreat to Dunkirk, a narrow area on the English Channel at the northern tip of France. In front of them was a rough sea, and behind them was a vicious pursuit. The troops lost their armor and collapsed, unable to organize a last-ditch battle. The only hope to avoid destruction was to cross the sea from Dunkirk and withdraw to England. By this time, the German armored forces had advanced to a place where Dunkirk could be seen, and were ready to go into final battle. Just as the situation was extremely critical, Hitler suddenly issued an order to stop the tank troops at the canal line and not to advance. This gave the British and French forces an unexpected and rare respite. The Allied soldiers rushed to repair the fortifications and cover the retreat. The British Admiralty, on Churchill's order, began to carry out a large retreat called the "Engine Plan". The British had long been prepared for the retreat, and the Admiralty quickly recruited more than 850 ships of all types, from cruisers and destroyers to ordinary yachts and wooden sailing ships, many of which were volunteer-piloted by the residents of the British seaside cities. The French Navy and merchant ships also participated in the operation. From May 27 to June 4, British and French sailors and sailors braved heavy bombing and artillery fire from German Stuka bombers, and after nine days and nights of hard work, more than 338,000 troops were withdrawn from the German tiger's mouth to the British Isles. Among them, 220,000 British troops and more than 80,000 French troops. These troops later became the backbone of the counteroffensive. During the withdrawal, tens of thousands of British and French troops died, more than 40,000 were captured, and 243 large and small ships were sunk. The weapons, equipment and vehicles of all 10 divisions of the British Expeditionary Force became the spoils of war for the Germans. This was the Dunkirk evacuation known as "one of the wonders in the history of war". On May 22, about 40 divisions of the Anglo-French coalition were surrounded. In the Dunkirk area on the border between Belgium and France, the British army was ready to lose all their weapons when they retreated, discarding 2,400 guns and 700 tanks. At 18:57 on May 26, the British Navy began to execute the plan to withdraw from Dunkirk. For the withdrawal, the British lost 226 ships and 302 combat aircraft. The British army withdrew to the mainland. They experienced "a great miracle in the history of war." On June 4, the Germans occupied Dunkirk, captured more than 40,000 French troops, and occupied northern France. The Germans attacked Paris southward. The French hastily organized the "Weigang Line." At dawn on June 5, the Germans attacked southward in two ways. Dunkirk The captured British personnel near Dunkirk, the Germans occupied Dunkirk, the British and French mobilized various ships to Dunkirk to transport the Allied officers and soldiers, the British and French Allied officers and soldiers crossed the sea and retreated to the British Isles, the French destroyer "Storm" was bombed by German planes during the withdrawal mission, and the British and French officers and soldiers crowded on the deck jumped into the sea to escape.
