On October 6, 1853, The Church of Jesus Christ of Latter-day Saints called 21 men to a mission to the Indians inhabiting the southern parts of the Territory of Utah, sanctioned by Governor Young. Six months later, on April 10, 1854, those previously called were set apart by the Council of the Twelve Apostles of the Church, with Rufus C Allen as captain, David Lewis as 1st Counselor, Daniel F. Atwood as 2nd Counselor, and T.D. Brown as recorder. They were commissioned to civilize and instruct the Indians in the region so they might inherit blessings pertaining to them because of the works and promises of their fathers. The company of 25 men and 6 wagons departed Great Salt Lake City on April 14, 1854, for the southern rim of the Great Basin, and Parley P. Pratt instructed them to be missionaries of the Church of Jesus Christ of Latter-day Saints and to behave accordingly. On May 2, 1854, the company arrived at Harmonie settlement and joined J.D. Lee and 30 others who had arrived earlier. Two weeks later Governor Brigham Young joined them at their camp on Ash Creek and counseled them that they were sent to save the remnants of Israel in the mountains, not to farm, build nice houses, fence fine fields, or help white men, but to save Native people. He directed them to move to a new location 4 miles north because Harmonie was too close to the river and could be washed out, and he outlined the construction of a fort 200 feet square with outside walls 2 feet thick and 10 feet high, inner walls 18 inches thick, a second story 9-12 feet high, adobe brick construction, and a rock cistern in the center. On Saturday, 20 May, 1854, accompanied by Truman O. Angell, architect for the Salt Lake Temple, Governor Young discussed the plan for the new fort and visited the proposed site, where he dug out the foundation for the southeast corner. The new fort was named Fort Harmony after the first settlement on Ash Creek, which itself was named for Harmony, Pennsylvania, where Joseph Smith, Jr., translated the Book of Mormon.
