The headquarters was reportedly created in 1961 when the southern and central branches of the Lao Dong Party (the Vietnamese Communist Party) merged into the Central Directorate for the South. An advance element of the Party's Central Committee, the headquarters was chartered to direct VC guerrilla operations in South Vietnam. Major General Tran Luong came south in May 1961 to reorganize the structure of the Directorate and its subordinate regions, Military Regions 1, 2, 3, 4, 6 and 10, known collectively as the B-2 Front. In the process, he created COSVN.
