The Sepoy Mutiny started in earnest on 10 May 1857. It started when 85 members of the 3rd Bengal Light Cavalry were broken out of prison by their comrades. They were imprisoned because they refused to use cartridges they believed to be at odds with their religion.
Word of the mutineers’ actions spread throughout the region, leading to a full-scale uprising against the East India Company.
