Lê Duẩn
During the First Indochina War Lê Duẩn served as the "Secretary of the Regional Committee of South Vietnam", at first in Cochinchina in 1946, but was reassigned to head the Central Office of South Vietnam from 1951 until 1954. The Viet Minh's position in the South became increasingly tenuous by the early to mid-1950s and in 1953 Lê Duẩn was replaced by his deputy Lê Đức Thọ and moved to North Vietnam.
