Hamengkubuwono IX
In early 1949, Hamengkubuwono IX conceived the idea of a major offensive to be launched against Yogyakarta and the Dutch troops occupying it. The purpose of this offensive was to show to the world that Indonesia still existed and that it was not ready to surrender. The idea was suggested to General Sudirman, the Commander of the Indonesian Army and received his approval. In February 1949, Hamengkubuwono IX had a meeting with then Lieutenant Colonel Suharto, the man chosen by Sudirman to be the field commander for the offensive. After this discussion, preparations were made for the offensive. This involved intensified guerilla attacks in villages and towns around Yogyakarta so as to make the Dutch station more troops outside of Yogyakarta and thin the numbers in the city itself. On 1 March 1949 at 6 am, Suharto and his troops launched the "1 March General Offensive". The offensive caught the Dutch by surprise. For his part, Hamengkubuwono IX allowed his palace to be used as a hide out for the troops. For 6 hours, the Indonesian troops had control of Yogyakarta before finally retreating. The offensive was a great success, inspiring demoralized troops all around Indonesia.
