In the aftermath of the Brunei Revolt, the remnants of the TNKU reached Indonesia. Possibly fearing British reprisals (which never eventuated), many Chinese communists, possibly several thousand, also fled Sarawak. Their compatriots remaining in Sarawak were known as the CCO by the UK but called the PGRS—Pasukan Gelilya Rakyat Sarawak (Sarawak People's Guerrilla Force) by Indonesia. Soebandrio met with a group of their potential leaders in Bogor, and Nasution sent three trainers from Resimen Para Komando Angkatan Darat (RPKAD) Battalion 2 to Nangabadan near the Sarawak border, where there were about 300 trainees. Some three months later, two lieutenants were sent there.
