The first blood was shed deep in Malaysian territory, with the Indonesian-staged Brunei Revolt on 8 December 1962. This operation, with the goal of seizing the oilfields as well as European hostages, was swiftly crushed by British forces that flew in from Singapore. The conflict proper, however, began in April of the following year, as 'volunteer' Indonesian forces made occasional raids across the Sarawak border. These raids were small, generally composed of groups smaller than platoon size, and their damage was minimised with relative ease by local security forces. The turning point came on 16 September, when the Malaysian Federation was formally created. In Indonesia, the response to the frustration of their plans to prevent the Federation's birth was serious and violent. A mob converged upon the British embassy in Jakarta, smashing windows and doors in protest. Sukarno authorised stronger raids by Indonesian regular forces, and even launched seaborne attacks into peninsular Malaysia. The raiding would continue for the duration of the conflict.
