In 1855 Brigham Young (1801-1877) called a group of missionaries to Lemhi County, Idaho to preach to the Shoshoni and Bannock Indians. The Mormon missionaries built a fort there, Fort Lemhi, and found the Indians to be friendly and receptive to their message. Yet, with the destruction of their crops by grasshoppers and the dwindling of their supplies, the Mormons found themselves in dire straits. In 1857, with word of the coming United States Army, a mountain man by the name of John W. Powell was able to convince the Indians to take advantage of the Mormons' weakened situation and steal their livestock. The ensuing conflict undermined the Mormon settlement's position and forced them to return to Utah.
