Piegan Blackfeet
On September 9, Stevens sent Mullan on a peace mission to the Salish nation. Mullan was instructed to convey the peaceful intentions of the government of the United States, implore the Salish to make peace with the Piegan Blackfeet, and express the desire of the United States to build up the settlement at St. Mary's Mission. Mullan was also to obtain several guides from the Salish, and to explore any nearby passes through the Rocky Mountains. Survey party aide F.H. Burr, three local men, a hunter, and a Piegan Blackfeet guide named White Crane accompanied him.
