The relationship between Vietnam and France - goes back to the nineteenth century. Influence in this region of France continued to expand during this century, and eventually Indochina (including Vietnam, Cambodia, and Laos) came together to form the Union of Indochina. This merging of the French colonies happened on October 17 of the year 1887. From December 6, 1946 the struggle for independence began. This war between the Vietminh and the French rulers eventually lasted until the year 1954. The Vietminh was a group that rebelled against the French colonial rulers.
The Vietminh had always gained ground during the war and it was decided on March 13, 1954 to open a final offensive at Dien Bien Phu airport. The battle started with artillery fire with many casualties on both sides. The fierce fighting made landing and taking off planes increasingly difficult and dangerous, and from March 23, flights from the airport were no longer carried out at all.
Subsequently, the war turned into a kind of trench warfare, with large losses on both sides. Initially, the Vietnamese mainly fired at the aircraft of the French army, so that the French soon could no longer take off planes and helicopters. |

The Trenches
Because the rainy season started at the end of April, the trenches and bunkers became impassable. The Vietnamese soldiers could barely hide and the French thought they could decide the battle in their favor.
However, the bad weather had made many roads impassable and therefore no French anti-aircraft guns could be brought in from Hanoi. The Vietnamese were thus able to hold out and would eventually win the decisive battle. Because the Vietnamese had deliberately not used their anti-aircraft guns, the French did not know where this gun was placed. By chance they discovered the bunker thanks to the enemy's fire.
After 16 days and nights, Vietnamese troops found the stone foundation of the bunker, which was left over from a structure built by French troops in 1940. Considering it was the bunker wall, Vietnamese troops explosively brought in 970 kg and detonated it at 6:30 PM on May 6, 1954.

The Crater
The surroundings of Dien Bien Phu turned into a large cloud of smoke, which destroyed almost everything about bunkers and trenches. Due to the surprising attack, the French could no longer regroup and suffered increasing losses. The fighting continued until late in the afternoon, but eventually the Vietnamese destroyed all posts and bunkers belonging to the French. Eventually, the red Vietnamese flag was raised on top of the last command post and Dien Bien Phu was officially dropped.
What remained was a crater in the ground where the blast had taken place.
