The main stronghold of the rebellious RMS group on Ambon was defeated by Indonesian forces in November 1950, while a smaller scale guerilla struggle continued on Ceram until 1962. The defeat on Ambon however resulted in the flight of the self-declared RMS government from the islands, and the formation of a government in exile in the Netherlands. The following year some 12,000 Moluccan soldiers accompanied by their families went to the Netherlands, where they established a "Republic of the South Moluccas" government-in-exile.
