Battlefield:VietnamThe Second Indochina War, 1954-1975, grew out of the long conflict between France and Vietnam. In July 1954, after one hundred years of colonial rule, a defeated France was forced to leave Vietnam. Nationalist forces under the direction of General Vo Nguyen Giap trounced the allied French troops at the remote mountain outpost of Dien Bien Phu in the northwest corner of Vietnam. This decisive battle convinced the French that they could no longer maintain their Indochinese colonies and Paris quickly sued for peace. As the two sides came together in Geneva, Switzerland, international events were already shaping the future of Vietnam's modern revolution.
