How did the Indian mutiny in 1857 begin?
On Sunday 9 May 1857, after some troopers had previously refused the new load and had been drummed out, the 3rd Light Cavalry and 11th and 20th Native Infantry at Meerut (Mirath), near Delhi, opened fire on their officers at church parade. In the absence of prompt action by the local British commander, they massacred the British families and then marched on Delhi, where the garrison also mutinied and massacred the Europeans.
