The Dutch with their local allies assaulted and finally wrested Malacca from the Portuguese in January 1641. This combined Dutch-Johor-Aceh efforts effectively destroyed the last bastion of Portuguese power, reducing their influence in the archipelago. The Dutch settled in the city as Dutch Malacca, however the Dutch had no intention to make Malacca their main base, and concentrated on building Batavia (today Jakarta) as their headquarters in the orient instead. The Portuguese ports in the spice-producing areas of Mollucas also fell to the Dutch in the following years. With these conquests, the last Portuguese colonies in Asia remained confined to Portuguese Timor, Goa, Daman and Diu in Portuguese India and Macau until the 20th century.
