Orders from James Buchanan to march to Utah to put down a supposed rebellion.
George W. Lay, Letter to William S. Harney, June 29, 1857, rep. in The Utah Expedition (Washington, D.C.: np., 1858), 7–9
The general-in-chief desires me to add in his name the following instructions, prepared in concert with the War Department, and sanctioned by its authority, whenever required.
The community and, in part, the civil government of Utah Territory are in a state of substantial rebellion against the laws and authority of the United States. A new civil governor is about to be designated, and to be charged with the establishment and maintenance of law and order. Your able and energetic aid, with that of the troops to be placed under your command, is relied to insure the success of his mission.
