The Yogyakarta and Surakarta Offensive (Indonesian: Serangan Yogyakarta dan Surakarta) were two major offensives during the Indonesian National Revolution. The offensive started with General Offensive of 1 March 1949 and the Siege of Surakarta. Each proved a major boast for the morale of the TNI despite defeats in both actions.
