General Vo Nguyen Giap, architect of Vietnam's military victories over France and the United States, died on Friday, aged 102, family members said.
The general was one of Vietnam's best known 20th century figures, ranked by historians among such military giants as Montgomery, Rommel and MacArthur.
The son of a peasant scholar, he was considered the mastermind of the historic defeat of the French in 1954 at Dien Bien Phu and the communist victory over U.S.-backed South Vietnam 21 years later.
