Chi Thanh is also a member of the military leadership of the Democratic Republic of Vietnam. In 1961, he continuously launched emulation movements in cooperatives, helping to stabilize the development situation in agricultural production in the North. From 1965 to 1967, he was assigned to the South, served as Secretary of the Central Department of South Vietnam, and the Political Commissar of the Liberation Army of the South. This time he took the name of Sáu Vi. When writing newspapers, he often took the pen name Trường Sơn. At the battlefield, he was the tactician of the South Vietnamese Liberation Army with the motto "Hold the enemy belt that hit", this approach uses maneuver to limit the fire's superiority of American troops. The Vietnamese claim that Nguyễn Chí Thanh died in Hanoi on July 7, 1967, due to a heart attack in Hanoi whilst reporting to President Hồ Chí Minh on the situation in the South. The United States claims that Thanh was severely wounded during a B-52 raid on COSVN, evacuated overland to Phnom Penh and then flown to Hanoi where he died of his wounds. In the aftermath of Thanh's death the party purged dozens of senior members who held more moderate positions in contrast to the more belligerent stance of Lê Duẩn and his allies. Phạm Hùng another close ally of Lê Duẩn was appointed to replace Thanh as head of COSVN.
