They claimed to have arrested several generals belonging to a conspiracy, the "Council of Generals", that had plotted a military coup against the government of President Sukarno. They further alleged that this coup was to take place on Armed Forces Day (5 October) with the backing of the CIA and that the Council would then install themselves as a military junta. Furthermore, the soldiers proclaimed the establishment of a "Revolutionary Council" consisting of various well-known military officers and civilian leaders that would be the highest authority in Indonesia. Additionally, they declared President Sukarno's Dwikora Cabinet as invalid ("demisioner").
