The South Sulawesi Campaign (10 December 1946 – 21 February 1947) was a campaign during the Indonesian National Revolution. It was a counter-insurgency offensive of the special forces of the KNIL against Indonesian infiltrations from Java and pro-Indonesian local militias. It was masterminded by the controversial Raymond Westerling, a captain in the KNIL (Royal Netherlands East Indies Army). Westerling's operation, which started in December 1946 and ended in February 1947, succeeded in eliminating the insurgency and undermining local support for the Republicans by instituting summary executions of suspected enemy fighters.
