The siege of Bangalore was a siege of the town and fortifications of Bangalore during the Third Anglo-Mysore War by forces of the British East India Company, led by Charles, Earl Cornwallis against a Mysorean garrison, while Tipu Sultan, Mysore's ruler, harried the camps and positions of the besiegers.

This lay-out was a feature of almost all the cities or settlements in India, the fort providing a place of refuge for most of the inhabitants if the pettah was in danger of capture.

The fort at Bangalore had a perimeter of about one mile; it was of solid masonry, surrounded by a wide ditch which was commanded from 26 towers placed at intervals along the ramparts.

To its north lay the pettah, several miles in circumference and protected by an indifferent rampart, a deep belt of thorn and cactus, and a small ditch.

Over the next twelve days, two companies of the Madras Pioneers provided sappers for eight batteries, dug several parallels and a trench up to the fort ditch.

Captain Kyd, of the Bengal Engineers then managed to breech the walls with mortars,[3] and Cornwallis elected to attack secretly on the night of 21 March 1791.

With a breach made, the main stormers rushed in and the fort was captured after a hand-to hand fight in which a thousand defenders were killed.

[6][7] Today, very little remains to remind people of the battle, except for a plaque (see picture), which reads "Through this breach the British assault was delivered.
