The Siege of Madras was a siege of Madras, British India, between December 1758 and February 1759 by French forces under the command of Lally during the Seven Years' War. The British garrison was able to hold out until it was relieved. The British fired 26,554 cannon balls and more than 200,000 cartridge rounds in defence of the town. The failure to take Madras was a huge disappointment for the French and a massive setback to their campaign in India compounded by the later Battle of Wandiwash.
