Why was the balloon raised on the beach when the Normandy landings were successful

The landing ground on Normandy Beach was used for two purposes: a barrage balloon and an artillery school-firing airship.

1. The moored anti-aircraft balloon is mainly used for key areas and field air defense, and is used for the air defense of the landing fleet during the Normandy landing operation, and multi-layer air defense blocking balloons are deployed on both sides of the landing site to prevent the German Air Force fighters from breaking through the airspace of the landing site and causing a large number of casualties to the landing personnel and equipment.

The anti-aircraft arrest balloon is a military tethered balloon, generally made of rubber and nylon membrane, plus a thin metal protective plate. The balloon is made up of many sac-shaped balloons, and even if it is hit by artillery fire, it is only partially damaged, and the total lift can be largely unchanged. There are two ways to arrange it in the air:

Skirt and tandem. The skirt is a series of balloons connected by steel cables that rise into the air in parallel. The barricade cable is laid between the connecting cables, forming a cable curtain like a skirt.

The tandem type is divided into two layers, and the balloons form a group of three balloons, and the steel cables are connected into a spider web.

2. The airship in front of the landing site is an artillery school-firing airship, equipped with telescopes, aerial cameras, electronic reconnaissance instruments, and radio communication equipment. For reconnaissance of targets difficult to observe by ground observation posts and correction of support fleet shots on the sea surface.

I remember what it was called, I forgot.

The Normandy landings were a historic battle in the latter part of World War II. In the early summer of 1944, the victory of the Soviet army over the German army on the Eastern Front was a foregone conclusion, and the Allies, in order to fulfill the agreement reached by the leaders of the United States, Britain, and the Soviet Union at the Tehran Conference in November 1943 on the opening of a second European theater on the Western Front, decided to land in the Normandy area of France and launch a counterattack against the troops of Nazi Germany.

In the early hours of June 6, a military operation, codenamed "D" Day, began on the beaches of Normandy. The United States-led Allied forces under the command of General Eisenhower, Anglo-American Allied forces on June 6, 1944.

Scene of the landing in Normandy, France.

Led by more than 20,000 paratroopers, nearly 160,000 troops, under the cover of the air force, set sail from Portsmouth and crossed the English Channel, breaking through the German defense line -- the "Atlantic Barrier" -- in one fell swoop, and putting the German army in a situation where they were exposed to the enemy on their backs. In this landing operation, the Allies dispatched 1,200 warships, 10,000 aircraft, 4,126 landing craft, 804 transport ships, hundreds of tanks, and 156,000 officers and men (730,000 Americans, 830,000 British and Canadians) to launch a fierce attack on Normandy beaches in five directions and begin the landing. The landing beach stretches from the estuary bay of the Orne River to the southeastern part of the Cotentin Peninsula.

On the 12th, the Allied landing sites were already connected. On 5 July, the Allied landings in Normandy had reached 1 million men. By the end of the battle on July 24, the Allies had committed 2.88 million men, more than 5,300 warships, and more than 13,700 warplanes.

The Germans committed 510,000 troops. During the battle, the Allies destroyed 1140000 German troops, 2,117 tanks and 245 aircraft. On the Allied side, 12,200,000 soldiers were killed.

After the war, they were buried according to their nationality in 28 military cemeteries in the Normandy area. After that, the Allies continued to advance into the heart of Europe, liberating France and Belgium in three months, and invading Germany proper. The Allied victory opened up a second battlefield in Europe and hastened the demise of fascist Germany.

This battle is also known as the Battle of the Overlord. The scale of the Normandy landings and the brutality of the battles are rare in the history of human warfare.
