Điện Biên Phủ ending scene

The Battle of Dien Bien Phu (French: Bataille de Diên Biên Phu; Vietnamese: Chiến dịch Điện Biên Phủ) was the climactic confrontation of the First Indochina War between the French Union's French Far East Expeditionary Corps and Viet Minh communist-nationalist revolutionaries. The battle occurred between March and May 1954 and culminated in a comprehensive French defeat that influenced negotiations over the future of Indochina at Geneva. Military historian Martin Windrow wrote that Dien Bien Phu was "the first time that a non-European colonial independence movement had evolved through all the stages from guerrilla bands to a conventionally organized and equipped army able to defeat a modern Western occupier in pitched battle."
The movie:
Diên Biên Phu (French for Điện Biên Phủ) is a 1992 film written and directed by French veteran Pierre Schoendoerffer. With its huge budget, all-star cast, and realistic war scenes produced with the cooperation of the French and Vietnamese armies, Dîen Bîen Phu is regarded by many as one of the more important war movies produced in French filmmaking history. It portrays the 55-day siege of Dien Bien Phu (1954), the last battle by the French Union's colonial army in the First Indochina War during the final days of French Indochina, which was soon after divided into North and South Vietnam. This was a prelude to the Second Indochina War, known in the United States as the Vietnam War.
