212 Seeret NOFOftN Chapter 5 Long unhappy with President Achmed Sukarno's perceived sym pathy to Communism and his institution of "guided democracy" in Indonesia, the CIA, after consultation with the State Department, be gan in early l 957 to supply financial assistance to a group of dissident Indonesian Army officers on the island of Sumatra. By 25 September 1957, the National Security Council had become concerned with the course of events in Indonesia and on its recommendation President Eisenhower authorized the Agency to "employ all feasible covert means" to support the dissidents. Planning for increased aid of all types began immediately, and in January 1958 a US arms shipment for the dissidents arrived in Sumatra. Then on 10 February, the situa tion came to a head. While Sukarno was out of the country on a state visit to Japan, the dissident army colonels, without consulting CIA, organized a Revolutionary Council in Padang, West Sumatra, and de manded the abolition of President Sukarno's "guided democracy." Five days later, this council proclaimed itself the new "Revolutionary Government" of Indonesia. President Sukarno's armed forces re sponded swiftly to this threat. In late February the Indonesian Air Force began bombing dissident strongholds, and by mid-March gov ernment forces were conducting an all-out air-sea-land drive against the rebel-held areas in central Sumatra. Although the Sumatran rebels were falling back, additional unrest broke out over 1,800 miles away in the islands of Celebes (Sulawesi), and CIA quickly began supply ing weapons to these dissidents, too.11 Increasingly involved in Indonesia, the Agency urgently needed accurate information on the situation there. As in previous crises, U-2s flew reconnaissance missions. On 24 March 1958, the Development Projects Staff moved the entire complement of Detachment C's pilots and planes from Japan to a base more easily accessible to Indonesia: Cubi Point Naval Air Station in the Philippines. Cubi Point was far from any facility that could develop and interpret the U-2 photographs, so two Photo-Intelligence Division employees went to Clark Airfield, just 30 minutes by air from Cubi Point, to establish a forward processing center. They arrived on 28 March and had the photo lab ready to go on the following day.:?J "I Fovert Support to Indonesian Revolutionary Government. /957-1958. 2 vols., Clandestine Service Historical Series, CSHP-53 (CIA: History Staff, 1970) (S): John Prados, Presidents' Secret Wars: CIA and Pentagon Covert Operations Since World War I/ (New York.
