After the war with the British, the Chakmas became very weak militarily. The [[Lushai]] used to make frequent murderous raids on British subjects on the grounds that their hunting ground was converted to a tea garden by the British in [[Cachar]], [[Noakhali]], [[Comilla]] and other neighbouring tracts under Rani Kalindi. They raided Chittagong Hill Tracts and the neighbouring tracts in 1847, 1848, 1859 and 1860. As a consequence, with a view to paying attention to the areas experiencing repeated raids and to protecting the people from the aggression of the independent tribes living further east but primarily to occupy the Chakma land, the Lieutenant Governor of Bengal recommended the removal of the hill tracts from the regulation district and the appointment of a superintendent over the tribes.
