The Battle of Chandannagar was a successful attack on the French Indies Company settlement of Chandernagore by a British force under the command of Robert Clive and Charles Watson on 23 March 1757 during the Seven Years' War and the Third Carnatic war. Chandernagore remained under military occupation by the British until the signing of the Treaty of Paris in 1763, which brought an end to the war.
