On the 15th of September, 1857, Governor Young issued his proclamation, in the style of an independent sovereign, announcing his purpose to resist by force of arms the entry of the United States troops into our own Territory of Utah. By this he required all the forces in the Territory to "hold themselves in readiness to march at a moment's notice to repel any and all such invasion," and established martial law from its date throughout the Territory. These proved to be no idle threats. Forts Bridger and Supply were vacated and burnt down by the Mormons to deprive our troops of a shelter after their long and fatiguing march. Orders were issued by Daniel H. Wells, styling himself "Lieutenant-General, Nauvoo Legion," to stampede the animals of the United States troops on their march, to set fire to their trains, to burn the grass and the whole country before them and on their flanks, to keep them from sleeping by night surprises, and to blockade the road by felling trees and destroying the fords of rivers, etc.
These orders were promptly and effectually obeyed. On the 4th of October, 1857, the Mormons captured and burned, on Green River, three of our supply trains, consisting of seventy-five wagons loaded with provisions and tents for the army, and carried away several hundred animals. This diminished the supply of provisions so materially that General Johnston was obliged to reduce the ration, and even with this precaution there was only sufficient left to subsist the troops until the 1st of June.
Our little army behaved admirably in their encampment at Fort Bridger under these trying privations. In the midst of the mountains, in a dreary, unsettled, and inhospitable region, more than a thousand miles from home, they passed the severe and inclement winter without a murmur. They looked forward with confidence for relief from their country in due season, and in this they were not disappointed.
The Secretary of War employed all his energies to forward them the necessary supplies and to muster and send such a military force to Utah as would render resistance on the part of the Mormons hopeless, and thus terminate the war without the effusion of blood. In his efforts he was efficiently sustained by Congress. They granted appropriations sufficient to cover the deficiency thus necessarily created, and also provided for raising two regiments of volunteers "for the purpose of quelling disturbances in the Territory of Utah, for the protection of supply and emigrant trains, and the suppression of Indian hostilities on the frontiers." Happily, there was no occasion to call these regiments into service. If there had been, I should have felt serious embarrassment in selecting them, so great was the number of our brave and patriotic citizens anxious to serve their country in this distant and apparently dangerous expedition. Thus it has ever been, and thus may it ever be.
The wisdom and economy of sending sufficient reenforcements to Utah are established, not only by the event, but in the opinion of those who from their position and opportunities are the most capable of forming a correct judgment. General Johnston, the commander of the forces, in addressing the Secretary of War from Fort Bridger under date of October 18, 1857, expresses the opinion that "unless a large force is sent here, from the nature of the country a protracted war on their [the Mormons's] part is inevitable." This he considered necessary to terminate the war "speedily and more economically than if attempted by insufficient means."
In the meantime it was my anxious desire that the Mormons should yield obedience to the Constitution and the laws without rendering it necessary to resort to military force. To aid in accomplishing this object, I deemed it advisable in April last to dispatch two distinguished citizens of the United States, Messrs. Powell and McCulloch, to Utah. They bore with them a proclamation addressed by myself to the inhabitants of Utah, dated on the 6th day of that month, warning them of their true condition and how hopeless it was on their part to persist in rebellion against the United States, and offering all those who should submit to the laws a full pardon for their past seditions and treasons. At the same time I assured those who should persist in rebellion against the United States that they must expect no further lenity, but look to be rigorously dealt with according to their deserts. The instructions to these agents, as well as a copy of the proclamation and their reports, are herewith submitted. It will be seen by their report of the 3d of July last that they have fully confirmed the opinion expressed by General Johnston in the previous October as to the necessity of sending reenforcements to Utah. In this they state that they "are firmly impressed with the belief that the presence of the Army here and the large additional force that had been ordered to this Territory were the chief inducements that caused the Mormons to abandon the idea of resisting the authority of the United States. A less decisive policy would probably have resulted in a long, bloody, and expensive war."
These gentlemen conducted themselves to my entire satisfaction and rendered useful services in executing the humane intentions of the Government.
It also affords me great satisfaction to state that Governor Cumming has performed his duty in an able and conciliatory manner and with the happiest effect. I can not in this connection refrain from mentioning the valuable services of Colonel Thomas L. Kane, who, from motives of pure benevolence and without any official character or pecuniary compensation, visited Utah during the last inclement winter for the purpose of contributing to the pacification of the Territory.
I am happy to inform you that the governor and other civil officers of Utah are now performing their appropriate functions without resistance. The authority of the Constitution and the laws has been fully restored and peace prevails throughout the Territory.
A portion of the troops sent to Utah are now encamped in Cedar Valley, 44 miles southwest of Salt Lake City, and the remainder have been ordered to Oregon to suppress Indian hostilities.
