Throughout this vast line of road, the only white inhabitants are the garrisons of the military posts, the keepers of mail-stations, and voyageurs and mountaineers, whose cabins may be found in every locality favorable to Indian trade. These last are a singular race of men, fast disappearing, like the Indian and the buffalo, their neighbors. Most of them are of French extraction, and some have died without having learned to speak a word of English. Their wealth consists in cattle and horses, and little stocks of goods which they purchase from the sutlers at the forts or the merchants at Salt Lake City. Some of the more considerable among them have the means of sending to the States for an annual supply of blankets, beads, vermilion, and other stuff for Indian traffic; but the most are thriftless, and all are living in concubinage or marriage with squaws, and surrounded by troops of unwashed, screeching half-breeds. Once in from three to six years, they will make a journey to St. Louis, and gamble away so much of their savings since the last visit as has escaped being wasted over greasy card-tables during the long winter-evenings among the mountains. The Indian tribes along the way are numerous and formidable, the road passing through country occupied by Pawnees, Cheyennes, Sioux, Arapahoes, Crows, Snakes, and Utahs. With the Cheyennes war had been waged by the United States for more than two years, which interfered seriously with the expedition; for, during the month of June, a war-party from that tribe intercepted and dispersed the herd of beef-cattle intended for the use of the army.

The natural characteristics of the entire route are as unpromising as those of its inhabitants. At the distance of about two hundred miles from the Missouri frontier the soil becomes so pervaded by sand, that only scientific agriculture can render it available. Along the Platte there is no fuel. Not a tree is visible, except the thin fringe of cottonwoods on the margin of the river, all of which upon the south bank, where the road runs, were hewed down and burned at every convenient camp, during the great California emigration. When the Rocky Mountains are entered, the only vegetation found is bunch-grass, so called because it grows in tufts,—and the artemisia, or wild sage, an odorous shrub, which sometimes attains the magnitude of a tree, with a fibrous trunk as thick as a man's thigh, but is ordinarily a bush about two feet in height. The bunch-grass, grown at such an elevation, possesses extraordinary nutritive properties, even in midwinter. About the middle of January a new growth is developed underneath the snow, forcing off the old dry blade that ripened and shed its seed the previous summer. From Fort Kearney to Fort Laramie, almost the only fuel to be obtained is the dung of buffalo and oxen, called, in the vocabulary of the region, "chips,"—the argal of the Tartar deserts. Among the mountains the sage is the chief material of the traveller's fire. It burns with a lively, ruddy flame, and gives out an intense heat. In the settlements of Utah all the wood consumed is hauled from the cañons, which are usually lined with pines, firs, and cedars, while the broadsides of the mountains are nothing but terraces of volcanic rock. The price of wood in Salt Lake City is from twelve to twenty dollars a cord.

From this brief review of the natural features of the country, some idea may be formed of the intensity of the religious enthusiasm which has induced fifty thousand Mormon converts to traverse it, many of them on foot and trundling handcarts, to seek a home among the valleys of Utah, in a region hardly more propitious; and some idea, also, of the difficulties which were to attend the march of the army.

During the spring of 1857, the preparations for the expedition were hurried forward, and in June the whole force was collected at Fort Leavenworth. All Western Missouri was in a ferment. The river foamed with steamboats freighted with military stores, and the levee at Leavenworth City was covered all summer long with the frames of wagons. Between the 18th and the 24th of July, all the detachments of the little army were on the march, except a battalion of two companies of infantry, which had been unable to join their regiment at the time it moved from Minnesota, and the Second Dragoons, which Governor Walker retained in Kansas to overawe the uneasy people of the town of Lawrence. General Harney also tarried in Kansas, intending to wait until after the October election there, at which disturbances were anticipated that it might be necessary to quell by force.

At Washington, movements of equal importance were taking place. The Postmaster-General, in June, annulled the contract held by certain Mormons for the transportation of the monthly mall to Utah, ostensibly on account of non-performance of the service within the stipulated time, but really because he was satisfied that the mails were violated, either en route or after arrival at Salt Lake City. The office of Governor of the Territory was offered by the President to various persons, and finally accepted, July 11th, by Alfred Cumming, a brother of the Cumming of Georgia who fought multitudinous duels with McDuffie of South Carolina, all of which both parties survived. Mr. Cumming had been a sutler during the Mexican War, and more recently a Superintendent of Indian Affairs on the Upper Missouri. He was reputed to be a gentleman of education, ambition, and executive ability. The office of Chief Justice was conferred on Judge D.R. Eckels, of Indiana, a person well fitted for the position by the circumstances of his early life, of the utmost determination, and whose judicial integrity was above suspicion.

The news of the stoppage of the mail reached Salt Lake Valley July 24th, an eventful anniversary in the history of Mormonism. It was on the 24th of July, 1847, that Brigham Young entered the Valley from the East, and the day had always afterwards been kept as a holiday of the Church. On this occasion, the celebration was held in Cottonwood Cañon, one of the wildest and grandest gorges among the Wahsatch Mountains, opening at the foot of the Twin Peaks, about twenty miles southeast from Salt Lake City. Thither more than twenty-five hundred people had flocked from the city on the previous day, and prepared to hold their festival under bowers built of fragrant pines and cedars around a little lake far up among the mountains. During the afternoon of the 24th, while they were engaged in music, dancing, and every manner of lively sport, two dusty messengers rode up the cañon, bringing from the States the news of the stoppage of the mail and of the approaching march of the troops. This mode of announcement was probably preconcerted with Brigham Young, who was undoubtedly aware of the facts on the preceding day. A scene of the maddest confusion ensued, which was heightened by the inflammatory speeches of the Mormon leaders. Young reminded the fanatical throng, that, ten years ago that very day, he had said, "Give us ten years of peace and we will ask no odds of the United States"; and he added, that the ten years had passed, and now they asked no odds,—that they constituted henceforth a free and independent state, to be known no longer as Utah, but by their own Mormon name of Deseret. Kimball, the second in authority in the Church, called on the people to adhere to Brigham, as their "prophet, seer, and revelator, priest, governor, and king." The sun set on the first overt act in the rebellion. The fanatics, wending their way back to the city, across the broad plain, in the moonlight, were ready to follow wherever Brigham Young might choose to lead.

On the succeeding Sundays the spirit of rebellion was breathed from the pulpit in language yet more intemperate, and often profane and obscene. Military preparations were made with the greatest bustle; and the Nauvoo Legion—under which name, transplanted from Illinois, the militia were organized—was drilled daily in the streets of the city. The martial fervor ran so high that even the boys paraded with wooden spears and guns, and the little ragamuffins were inspected and patted on the head by venerable and veritable Fathers of the Church.

In total ignorance that the standard of rebellion had already been raised, General Harney, in the beginning of August, detached Captain Van Vliet, the Quarter-master on his staff, to proceed rapidly to Utah to make arrangements for the reception of the army in the Valley. He passed the troops in the vicinity of Fort Laramie. About thirty miles west of Green River he was met by a party of Mormons, who escorted him, accompanied only by his servant, to the city. There he was politely treated, but informed that his mission would be fruitless, for the Mormon people were determined to resist the ingress of the troops. At a meeting in the Tabernacle, at which the Captain was present on the platform, when Brigham Young called on the audience for an expression of opinion, every hand was raised in favor of the policy of resistance, and in expression of willingness, if it should become necessary, to abandon harvest and homestead, retreat with the women to the mountains, and wage there a war of extermination. They took pains to conduct the Captain through the well-kept gardens and blooming fields, to show him their household comforts, the herds of cattle, the stacks of hay and grain, and all their public improvements, in order to present a contrast between such plenty and prosperity and such a scene of desolation as they depicted. Profoundly impressed by the devotion of the people to their leaders, he started on his return, accompanied by Mr. Bernhisel, the Mormon delegate to Congress. Two days after he left the city, a proclamation was issued by Young, in his capacity of Governor, in which the army was denounced as a mob and forbidden to enter the Territory, and the people of Utah were summoned to arms to repel its advance.

When this document reached the troops, they had already crossed the Territorial line, and were prepared for its reception by the report of Captain Van Vliet as he passed them on his return to the States. Their position was embarrassing. In the absence of General Harney, each separate detachment constituted an independent command. The senior officer present was Colonel Alexander, of the Tenth Infantry, a thorough soldier in the minutiae of his profession, and distinguished by gallantry during the Mexican War. He resolved, very properly, in view of his seniority, to assume the command-in-chief until General Harney should arrive from the East. On the 27th of September, before the proclamation was received, the first division of the army crossed Green River, having accomplished a march of a thousand miles in little more than two months. That same night it hastened forwards thirty miles to Ham's Fork,—a confluent of Black's Fork, which empties into Green River,—where several supply-trains were gathered, upon which there was danger that the Mormons would make an attack. The other divisions followed within the week, and the whole force was concentrated. On the night of October 5th, after the last division had crossed the river, two supply-trains, of twenty-five wagons each, were captured and burned just on the bank of the stream, by a party of mounted Mormons led by a man named Lot Smith, and the next morning another train was destroyed by the same party, twenty miles farther east, on the Big Sandy, in Oregon Territory. The teamsters were disarmed and dismissed, and the cattle stolen. No blood was shed; not a shot fired. Immediately upon the news of this attack reaching Ham's Fork, Colonel Alexander, who had then assumed the command-in-chief, dispatched Captain Marcy, of the Fifth Infantry, with four hundred men, to afford assistance to the trains, and punish the aggressors, if possible. But when the Captain reached Green River, all that was visible near the little French trading-post was two broad, black rings on the ground, bestrewn with iron chains and bolts, where the wagons had been burned in corral. He was able to do nothing except to send orders to the other trains on the road to halt, concentrate, and await the escort of Brevet Colonel Smith, of the Tenth Infantry, who had started from the frontier in August with the two companies mentioned as having been left behind in Minnesota, and by rapid marches had already reached the Sweetwater. The condition of affairs at this moment was indeed critical. By the folly of Governor Walker's movements in Kansas the expedition was deprived of its mounted force, and consisted entirely of infantry and artillery. The Mormon marauding parties, on the contrary, which it now became evident were hovering on every side, were all well mounted and tolerably well armed. The loss of three trains more would reduce the troops to the verge of starvation before spring, in case of inability to reach Salt Lake Valley. Nothing was heard from General Harney, and in his absence no one possessed instructions adequate to the emergency.

To understand the movements which followed, it is necessary to describe briefly the topography of the country between Green River and the Great Salt Lake. The entire interval, one hundred and fifty miles in breadth, is filled with groups and chains of mountains, the direct route through which to Salt Lake City lies along water-courses, following them through cañons so narrow that little science is necessary to render the natural defences impregnable. In this respect, and in the general character of the scenery, it bears much resemblance to the Tyrol. In the narrowest of these gorges, Echo Cañon, twenty-five miles in length, whose walls of rock often approach within a stone's throw of each other, it became known that the Mormons were erecting breastworks and digging ditches, by means of which they expected to be able to submerge the road to the depth of several feet, for miles. The only known mode of avoiding a passage through this gorge was by a circuitous route, following the eastern slope of the rim of the Great Basin northward, more than a hundred miles, to Soda Springs, at the northern bend of Bear River, the principal tributary of the Salt Lake,—then crossing the rim along the course of the river, and pursuing its valley southward, and that of the Roseaux or Malade, into Salt Lake Valley. The distance of Salt Lake City from the camp on Ham's Fork was by this route nearly three hundred miles,—while the distance by the road past Fort Bridger, through the cañons, was less than one hundred and fifty miles. At that fort, about twenty miles west from the encampment of the army, the Mormon marauding parties had their head-quarters and principal dépôt. It was there that Colonel Alexander was ordered, about this time, by Brigham Young, to surrender his arms to the Mormon Quartermaster-General, on which condition and an agreement to depart eastward early the following spring, he and his troops should be fed during the winter; otherwise, Young added, they would perish from hunger and cold, and rot among the mountains. In his perplexity, Colonel Alexander called a council of war, and, with its approval, resolved to commence a march towards Soda Springs, leaving Fort Bridger unmolested on his left. For more than a fortnight the army toiled along Ham's Fork, cutting a road through thickets of greasewood and wild sage, incumbered by a train of such unwieldy length that often the advance-guard reached its camp at night before the rear-guard had moved from the camp of the preceding day, and harassed by Mormon marauding parties from the Fort, which hung about the flanks out of the reach of rifle-shot, awaiting opportunities to descend on unprotected wagons and cattle. The absence of dragoons prevented a dispersion of these banditti. Some companies of infantry were, indeed, mounted on mules, and sent to pursue them, but these only excited their derision. The Mormons nicknamed them "jackass cavalry." Their only exploit was the capture of a Mormon major and his adjutant, on whose person were found orders issued by D.H. Wells, the Commanding General of the Nauvoo Legion, to the various detachments of marauders, directing them to burn the whole country before the army and on its flanks, to keep it from sleep by night surprises, to stampede its animals and set fire to its trains, to blockade the road by felling trees and destroying river-fords, but to take no life. On the 13th of October, eight hundred oxen were cut off from the rear of the army and driven to Salt Lake Valley. Thus the weary column toiled along until it reached the spot where it expected to be joined by Colonel Smith's battalion, about fifty miles up Ham's Fork. The very next day snow fell to the depth of more than a foot. Disheartened, vacillating, and perplexed, Colonel Alexander called another council of war, and, acting on its judgment, resolved to retrace his steps. An express reached him that same day, from Colonel Smith, by which he was informed of the approach of Colonel Albert S. Johnston, of the Second Cavalry, who had been detailed to take command of the expedition in the place of General Harney, and now sent orders that the troops should return to Black's Fork, where he proposed to concentrate the entire army.
