Battle of Dien Bien Phu

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."
