The Anglo-Mysore Wars were a series of four wars fought during the last three decades of the 18th century between the Sultanate of Mysore on the one hand, and the British East India Company (represented chiefly by the neighbouring Madras Presidency), Maratha Empire, Kingdom of Travancore, and the Kingdom of Hyderabad on the other.
In the First Anglo-Mysore War (1767 – 1769), Hyder Ali enjoyed some measure of success against the British, almost capturing Madras.
Ali defeated William Baillie at the Battle of Pollilur in September 1780, and John Braithwaite at Kumbakonam in February 1782, both of whom were taken prisoner to Srirangapatana.
This war saw the comeback of Sir Eyre Coote, the British commander who defeated Ali at the Battle of Porto Novo and Arni.
Finally, the war ended with the signing of the Treaty of Mangalore on 11 March 1784, which restored the status quo ante bellum.
The Mysorean rockets used by Tipu during the Battle of Pollilur were much more advanced than any that the British East India Company had previously seen, chiefly because of the use of iron tubes for holding the propellant.
