The Capture of Trincomalee on 11 January 1782 was the second major engagement between Great Britain and the Dutch East India Company in the East Indies after outbreak of the Fourth Anglo-Dutch War. After capturing Negapatam, the major Dutch outpost in India, a British force assaulted the Dutch-controlled port of Trincomalee on the eastern coast of Ceylon, and successfully stormed Fort Fredrick and Fort Ostenburg to gain control of the city and the port.
