The Vellore mutiny, or Vellore Revolution, occurred on 10 July 1806 and was the first instance of a large-scale and violent mutiny by Indian sepoys against the East India Company, predating the Indian Rebellion of 1857 by half a century. The revolt, which took place in the Indian city of Vellore, lasted one full day, during which mutineers seized the Vellore Fort and killed or wounded 200 British troops. The mutiny was subdued by cavalry and artillery from Arcot.
