The victory at Plassey made British master of the then Bengal which contained the present Sahibganj District. In Santhal Pargana, they were up against a band of simple but determined opponents, the Paharias. Paharias were lovers of freedom and could not tolerate any intruder in their homeland. The English were very much concerned and Warren Hastings the Governor General of India organized a special corps of 800 men in 1772 to curb the Paharias. The corps was put under the command of Captain Brooke, who was appointed the Military Governor of the Jungle terai.
