In late 1961, President Kennedy sent Roger Hilsman, then director of the State Department's Bureau of Intelligence and Research, to assess the situation in Vietnam. There, Hilsman met Sir Robert Grainger Ker Thompson, head of the British Advisory Mission to South Vietnam, and the Strategic Hamlet Program was formed. It was approved by Kennedy and South Vietnam President Ngo Dinh Diem. It was implemented in early 1962 and involved some forced relocation, village internment, and segregation of rural South Vietnamese into new communities where the peasantry would be isolated from Communist insurgents. It was hoped that these new communities would provide security for the peasants and strengthen the tie between them and the central government. By November 1963, the program waned and officially ended in 1964.
