On April 6, 1855, Brigham Young issued a call at Salt Lake City to 27 elders of the Church of Jesus Christ of Latter-Day Saints to go into the Salmon River Country of Oregon Territory, where many tribes gathered to fish and hunt, to choose a location, found a mission, and teach the arts of husbandry and peace according to their gospel plan. The party traveled 380 miles in 22 days with 11 wagons, 46 oxen, 7 horses, and much cattle over mostly non-existent roads. Fort Lemhi, established June 18, 1855, became the site of the first irrigation project in the Great Northwest. It had two sections: a timber stockade 16 rods square surrounding 25 cabins, and a Spanish wall mud stock enclosure of the same size. In May 1857, Brigham Young and 142 people visited and approved the mission, and new settlers raised the population to more than 100 souls. About 100 Indians were converted. Indian raids on the mission and its abandonment in March 1858 were attributed to the influence of Johnston's Army encamped at Fort Bridger. Those killed were William Bailey Lake, James Miller, and George McBride, and those wounded were Andrew Quigley, Oliver Robinson, Lewis W. Shurtliff, Thomas Smith, and Fountain Welch.
