What did the Sepoy mutineers do in 1857?

In 1857, the Sepoy mutineers, primarily Indian soldiers in the British East India Company's army, revolted against their British officers due to grievances over issues such as cultural insensitivity, the introduction of the new Enfield rifle with cartridges rumored to be greased with animal fat, and general discontent with British rule. The uprising, known as the Sepoy Mutiny or the Indian Rebellion of 1857, spread across northern India and involved various segments of society, including peasants and local rulers. The rebellion was ultimately suppressed by British forces, leading to significant changes in British colonial policy and the dissolution of the East India Company in favor of direct British governance over India.
