The Battle of Dien Bien Phu is seen as the decisive battle of the First Indochina War between French troops and the Viet Minh (League for the Independence of Vietnam), a nationalist, pro-Soviet Union movement of Ho Chi Minh. This major confrontation occurred at Dien Bien Phu, a large heart-shaped valley located in northwestern part of Vietnam, near the border with Laos. The valley had to serve as a French forward operating base to conduct operations in the region. The main purposes were to cut off Viet Minh supply lines into Laos, a former member of French Indochina and an ally of France, and to successfully defeat the enemy. Nevertheless, the French garrison attracted the Viet Minh.
Despite their plans, the French were attacked and suffered a defeat. The leadership of the garrison absolutely failed, as well as the French leadership in Vietnam and France. The units stationed in the valley had to fight on its own. Some 6,000 reliable French troops (many African troops or Vietnamese auxiliaries preferred desertion to fighting) against more than 55,000 Viet Minh soldiers. The battle started on March 13, 1954 and was over 56 days later, on May 7. One of the Legion units had to fight until May 8. The result of the battle culminated in the French withdrawal from Southeast Asia, after almost 100 years.

Battle of Dien Bien Phu: French War Memorial
In the 1980s, a small French War Memorial was built in the Dien Bien Phu valley. In 1992, the memorial was found unkempt and in ruins by a former legionnaire, Rolf Rodel. Having joined the Legion in 1950, Staff Sergeant Rolf Rodel served as a commando leader with 10th Company, 3rd Battalion, 3e REI at Isabelle in 1954. Four times wounded during the decisive battle and imprisoned by the Viet Minh, this German legionnaire returned to the site to refresh his memories. He rebuilt the memorial on his own, in eight days.
Rolf Rodel returned to Vietnam two years later, in 1994. He bought a small piece of land and built from the very beginning a new War Memorial to commemorate with dignity the French soldiers fallen at Dien Bien Phu. After two months (February-April), the work was finished. It took another year until French officials considered to cover his expenses and to take care of the new Memorial. However, the monument was officially inaugurated as late as 1999, five years after its construction. Unfortunately, Rolf Rodel didn’t live to see it. He died on January 5, 1999.
