The Battle of Colachel (or The Battle of Kulachal) was fought on 10 August 1741 [O.S. 31 July 1741]between the Indian kingdom of Travancore and the Dutch East India Company. During the Travancore-Dutch War, King Marthanda Varma's (1729–1758) forces defeated the Dutch East India Company's forces led by Admiral Eustachius De Lannoy on 10 August 1741. The Dutch never recovered from the defeat and no longer posed a large colonial threat to India.
