2 to Nangabadan near the Sarawak border, where there were about 300 trainees. Some three months later, two lieutenants were also sent there. The Indonesians had planned to use the Sarawak Communists as an indigenous front for their operations during the Indonesian-Malaysian Confrontation. To support this ruse, they even named the organisation the North Kalimantan National Army (TNKU), to link the Sarawak Communists to the original Bruneian rebels. While the first raids included SCO members, they were often led by regular Indonesian officers or Non-commissioned officers from the Marine commandos (Korps Komando Operasi, KKO), the Army para-commandos (Regimen Para Kommando Angaton Darat, RPKAD), and the Air Force paratroopers ( Pasukan Gerak Tjepat, PGT). Following the 1965 failed coup, and subsequently, the military takeover in Indonesia, General Suharto launched a purge of Communist elements. Overnight, the Sarawak Communists in Indonesia lost a safe haven and the Indonesian military would subsequently cooperate with the Malaysians in counter-insurgency operations against their former allies. Despite the loss of an important ally, PARAKU and the PGRS continued fighting against the Malaysian government during the Sarawak Communist Insurgency which lasted until November 1990. Decline and fragmentation Between 1965 and 1990, there were skirmishes which pitted the Sarawak Communist Movement against the Malaysian armed forces. In response to the Communist insurgency, the Malaysian federal government created several "controlled areas" along the Kuching–Serian road in Sarawak's First and Third Divisions in 1965. These settlements were protected by barbed wire and modelled after the successful New Villages used earlier during the Malayan Emergency. As with the Briggs Plan, the "controlled areas" succeeded in denying the SCO access to food supplies and material from their Chinese and Dayak supporters. Following the 13 May Incident in 1969, all Communist elements were expelled from the SUPP and moderate elements gained control over the party. The SUPP then entered into a coalition with the ruling Bumiputera Party in the Sarawak State Legislative Assembly. On 30 March 1970, Wen Ming Chyuan, the Head of the Sarawak People's Guerrillas in Sarawak's First Division, formed the North Kalimantan Communist Party. However, 19 September 1971 was chosen as the official date of the formation of the party to coincide with the Pontianak Conference, which had been held on 17–19 September 1965. While the Pontianak Conference was regarded as the foundation of the Sarawak Communist Movement, none of the conference attendees were Communist. Instead, they consisted of members
