Bengal and Tripura

In September 1857, sepoys took control of the treasury in Chittagong. The treasury remained under rebel control for several days. Further mutinies on 18 November saw the 2nd, 3rd and 4th companies of the 34th Bengal Infantry Regiment storming the Chittagong Jail and releasing all prisoners. The mutineers were eventually suppressed by the Gurkha regiments. The mutiny also spread to Kolkata and later Dhaka, the former Mughal capital of Bengal. Residents in the city's Lalbagh area were kept awake at night by the rebellion. Sepoys joined hands with the common populace in Jalpaiguri to take control of the city's cantonment. In January 1858, many sepoys received shelter from the royal family of the princely state of Hill Tippera.

The interior areas of Bengal proper were already experiencing growing resistance to Company rule due to the Muslim Faraizi movement.
