The 19th Light Dragoons was a cavalry regiment of the British Army created in 1781 for service in British India. The regiment served in India until 1806, and in North America during the War of 1812, and was disbanded in Britain in 1821.

The siege of Seringapatam was the final confrontation of the Fourth Anglo-Mysore War between the British East India Company and the Kingdom of Mysore. The British, with the allied Nizam Ali Khan, 2nd Nizam of Hyderabad and Marathas, achieved a decisive victory after breaching the walls of the fortress at Seringapatam and storming the citadel. The leader of the British troops was Major General David Baird, among the lesser known allies were the Portuguese in Goa and Damaon. Tipu Sultan, the de facto ruler after the death of his father, who had usurped the throne of Mysore, was killed in the action. The British restored the Wodeyar dynasty back to power after the victory through a treaty of subsidiary alliance and Krishnaraja Wodeyar III was crowned the King of Mysore. However, they retained indirect control of the kingdom's external affairs.
