What is France's impregnable defense?

God just played a joke on France! Maginot line can't be destroyed, so let it be a decoration.

The construction of maginot line started at 1928 and was basically completed at 1940. It's worth 5 billion francs.

Macedonia's defense line is 390 kilometers long, the whole defense line safety zone is 4 ~ 14 kilometers deep, and the main defense zone (6 ~ 8 kilometers deep).

Ground fortifications take 5800 fortress as the backbone, and in combination with the terrain, deep crossing bunkers, anti-tank concrete roadblocks or trenches, metal piles or wooden stakes are set up to prevent infantry attacks, minefields, power grids, etc.

Underground fortifications include command post, personnel lounge, logistics warehouse, ambulance station, power station, filtering ventilation room, etc. The fortifications are interconnected and operated by electric vehicles in the tunnel.

This fortification, which took 13 years, all the financial revenue of France for several years and all the painstaking efforts of French military defense experts, was turned into a "defense line that God cannot break and destroy" by France.

Maginot line is really awesome! But it obviously has weaknesses. (pictured)

The key direction of maginot line is, of course, the eastern section of the Franco-German border.

Maginot line borders Belgium and Luxemburg in the northeast (they are British military allies). If the Germans attack from the northeast, they must pass through Belgium, and Britain is bound to go to war! Therefore, the northeast section is not the focus of Ma Qinuo's defense configuration.

Especially in the Ardennes Plateau, which is located at the triple junction of France, Belgium and Luxemburg, France believes that German mechanized troops cannot pass through on a large scale, so there is no key fortification, which has also become maginot line's weakness.

Germany's military deployment to attack France is very simple and clear!

German army groups A, B and C are scattered in maginot line.

Army Group C kept a feint in eastern France, and the French army was firmly tied to the defense line in eastern Ma Qinuo and did not dare to move.

Army B attacked the Netherlands and Belgium from the north, (mainly from the Netherlands and Belgium, leaving France and Britain busy supporting the Dutch and Belgian troops against Germany.

An armored division of an army suddenly crossed the Ardennes Plateau from the central line and broke through maginot line in one fell swoop.

After the German Army Group A broke into France, it made a detour to the west, forming a situation of attacking the French army west of maginot line with the Army Group B, forcing the French army to give up its position and flee to Dunkirton Beach with the defeated troops of Britain and Belgium. As Hitler ordered the guderian Tank Division to stop pursuing, the defeated troops of Britain, France and Belgium narrowly escaped the English Channel.

The German A.B Army turned back to the east and captured Paris, forming an encirclement of the defenders in eastern French Ma Qinuo, and the defenders were watching.

The French government announced its surrender, allowing the French army to walk out of the eastern defense line and hand over fortifications and weapons.

The joke that maginot line became a decoration lies in;

At that time, French military thought had changed from "all-round attack" to "all-round defense", but it still stayed in the position of "fortress to fortress" to fight World War I (Battle of the Somme) and consumed the mode of "ground meat" war.

France did not realize that the concentrated use of armored forces was highly mobile and lethal, which posed a fatal threat to rigid defense. Finally, it was "a little breakthrough and complete collapse" by the Germans.

Since then, "military deterrence plus mobile defense" has become a new military defense idea, and no country will "burn money" to build the military "Great Wall of Wan Li".
