The Battle of Dien Bien Phu was the climactic showdown of the First Indochina War between the French Union's French Far East Expeditionary Corps and Viet Minh communist-nationalist revolutionaries. It was, from the French view before the occasion, a set piece battle to draw out the Vietnamese and decimate them with predominant capability. The fight happened among March and May 1954 and finished in a far reaching French annihilation that impacted transactions over the future of Indochina at Geneva.
