A border city between France and Belgium.

The border city between France and Belgium is Dunkirk.

On the French-Belgian border, there is a small but powerful city, Dunkirk. It is small because its urban area is only 43.89 square kilometers, which is about equivalent to Shibantan Town, a town under the jurisdiction of Xindu District, Chengdu, Sichuan Province, with a population of only 90,000.

Dunkirk is famous for the Battle of Dunkirk in World War II and the "Dunkirk Retreat" of the British and French allied forces, and it was almost completely destroyed because of the war. After the war, the French people rebuilt the port and city of Dunkirk on the ruins, becoming a new metallurgical, petroleum, chemical and shipbuilding industrial base.

It is amazing because in 1940, a miracle was created here: in just nine days, 300,000 people were safely evacuated, followed by German pursuers and in front of the sea, which saved an important effective force for the allied forces to counterattack in the future and created a historical miracle.

Knowing that the soldiers are expensive and fast, they can be defeated. Why do you press the pause button for yourself at a critical moment and draw a stop line abruptly? Yes, it's about the Dunkirk retreat.
