On 30 September 1965, six of the most senior generals within the military and other officers were executed in an attempted coup. The insurgents, known later as the 30 September Movement, backed a rival faction of the army and took up positions in the capital, later seizing control of the national radio station. They claimed they were acting against a plot organised by the generals to overthrow Sukarno. Within a few hours, Major General Suharto, commander of the Army Strategic Reserve (Kostrad), mobilised counteraction, and by the evening of 1 October, it was clear that the coup, which had little co-ordination and was largely limited to Jakarta, had failed. Complicated and partisan theories continue to this day over the identity of the attempted coup's organisers and their aims. According to the Indonesian army, the PKI were behind the coup and used disgruntled army officers to carry it out, and this became the official account of Suharto's subsequent New Order administration. Most historians agree that the coup and the surrounding events were not led by a single mastermind controlling all events, and that the full truth will never likely be known.
