Mas Tirtodarmo Haryono

In the early hours of 1 October 1965, members of the Tjakrabirawa, calling themselves the 30 September Movement, broke into Haryono's home at Jalan Prambanan No. 8. His wife was woken by the group of men who told her that the general had been summoned by President Sukarno. Mrs Haryono returned to the bedroom, locking the door behind her and told her husband about what happened. She told him not to go, and to tell the guards to return at 8 a.m.

Haryono was in Jakarta when Indonesia declared independence. Like many Indonesian youths, Haryono joined other youths to fight the Dutch, then joined the Tentara Keamanan Rakyat (TKR), the forerunner of the Indonesian Army. Due to his superior education, he was made a major. His command of Dutch, English and German meant he was in demand during negotiations between Indonesia and the colonial forces. On 1 September 1945, he was appointed Head of the Communication Office in Jakarta. In 1946, he was made secretary to the Indonesian delegation in the negotiations with the Dutch and the British. In November 1949, he also served as the Secretary of the Disarming Section of the Defense Commission at the Dutch-Indonesian Round Table Conference, at which the Dutch agreed to transfer sovereignty to Indonesia. He returned to the Netherlands in July 1950 as military attaché to the Indonesian embassy in the Hague, then on his return to Indonesia in October 1954, he joined the Army General Staff as Army Quartermaster. From August 1962 to 1964 he was Army Inspector General, and in 1963 was also appointed head of the Strategic Materials Section of the Supreme Operational Command (KOTI). His final position, which he took up on 1 July 1964, was Third Deputy to Army Chief of Staff Lieutenant General Ahmad Yani.
