The Battle of Dien Bien Phu, a significant confrontation during the First Indochina War, unfolded from March to May 1954. French Union forces, led by Colonel Christian de Castries, built a fortified camp in Dien Bien Phu, Vietnam, intending to cut off Viet Minh supply lines into Laos. Opposing them were the Viet Minh, under General Vo Nguyen Giap, who had been fighting for Vietnamese independence from France.
Despite outnumbering the Viet Minh, the French were caught off guard by their opponent’s ability to transport heavy artillery over difficult terrain. Using a network of tunnels and trenches, the Viet Minh encircled and besieged the French, systematically capturing outlying fortifications. French attempts at relief were thwarted by poor weather and aggressive anti-aircraft fire.
By May, the French were cornered in a small area of the camp, their situation dire. On May 7, de Castries surrendered, marking a major victory for the Viet Minh. The battle’s outcome had far-reaching implications, leading to the Geneva Conference and the partitioning of Vietnam at the 17th parallel. It also marked the end of French colonial influence in Asia.
