The Siege of Negapatam was the first major offensive military action on the Indian subcontinent following the arrival of news that war had been declared between Great Britain and the Dutch Republic, beginning the Fourth Anglo-Dutch War. A British force besieged the Dutch-controlled port of Negapatam, the capital of Dutch Coromandel, on the eastern coast of India, which capitulated after the fortification's walls were breached. The Dutch garrison consisted of 500 European troops, 5,500 local troops, and 2,000 troops of Hyder Ali, the ruler of Mysore.
