Who was assigned by the British for the expedition on Singhbhum in AD 1767?

In 1767, Ferguson was assigned to the expedition to Singhbhum. He initially conquered Jhargram. The frightened rulers of Ramgarh, Silda, and Jambani accepted British subordination as a result of this mission. The company forces then marched to Dhalbhum and defeated the ruler, but the ruler of Dhalbhum burned his fort before fleeing, and it was taken by the British in 1767.
