In February 1966, Soekarno promoted Suharto to lieutenant-general (and to full general in July 1966). The killing of a student demonstrator and Soekarno's order for the disbandment of KAMI in February 1966 further galvanised public opinion against the president. On 11 March 1966, the appearance of unidentified troops around Merdeka Palace during a cabinet meeting (which Soeharto had not attended) forced Soekarno to flee to Bogor Palace (60 km away) by helicopter. Three pro-Soeharto generals, Major-General Basuki Rahmat, Brigadier-General M Jusuf, and Brigadier-General Amirmachmud went to Bogor to meet Soekarno. There, they persuaded and secured a presidential decree from Soekarno (see "Supersemar") that gave Suharto authority to take any action necessary to maintain security.
