The Battle of Madras or Fall of Madras took place in September 1746 during the War of the Austrian Succession when a French force attacked and captured the city of Madras from its British garrison. They occupied it until the end of hostilities when it was exchanged for a British conquest of Louisbourg in North America as part of the Treaty of Aix-la-Chapelle. One of the British defenders, Robert Clive made his name by escaping from the French captors and carrying news of the city's fall to his superiors at Fort St David.
