This treatise aims at giving a glimpse of the renowned frontier personalities shaping the British frontier policy acting in different capacities as civil and military officers under tyring circumstances in hostile clime to open up the North-east to the world. They studied the topography of the hills and plains, made survey of the forbidden land, mixed with the unknown people at the risk of their lives to know their customs and usages, gave a shape to their languages. Todays north east what we know now is the product of their hard labour, sacrifice and farsight.
