In this letter Henry Leavenworth, founder of Cantonment Leavenworth (later Ft. Leavenworth) described the location he had chosen as the site of this military outpost. Leavenworth also mentioned that, because various tribes of Indians would certainly be coming to visit the new fort, it would be best for John Dougherty, the Indian agent in Council Bluffs, Iowa, to move his office into the fort.
