The party had to undergo not only terrible discomforts arising from the physical conditions of the country, but was also harassed by hostile Indians, who stole some of their stock. The expedition fortunately escaped with the loss of only one man, although parties in advance and in their rear were plundered and slaughtered. Speaking of their travelling alone in twenty-seven days a distance of five hundred and fifty miles through this inhospitable region, Frémont comments, that although their lonely journey gave them the advantage of more grass, yet they "had the disadvantage of finding also the marauding savages who had gathered down upon the trail, waiting the approach of their prey. This greatly increased our labors, besides costing us the life of an excellent man. We had to move all day in a state of watch and prepare for combat, scouts and flankers out, a front and rear division of our men, and baggage animals in the centre. At night camp duty was severe; those who had toiled all day had to guard by turns the camp and horses all night. Frequently one-third of the whole party were on guard at once, and nothing but this vigilance saved us from attack. We were constantly dogged by bands and even whole tribes of the marauders." Reaching, in Southern Utah, the head-waters of the Virgin River, where Santa Fé trains usually halt to recruit the strength of their animals in its grassy meadows, Frémont was joined by the famous trapper, Joseph Walker, who consented to serve as guide in the departure to the northeastward, as they now quitted the Spanish trail. Frémont then skirted the eastern edge of the great interior basin and visiting Sevier and Utah Lakes, thus completed practically the circuit of the basin. He then turned eastward through the valleys of the Du Chesne and Green Rivers, tributaries to the Colorado, and pushing through the very heart of the Rocky Mountains, by the way of the pass near Leadville, at an elevation of eleven thousand two hundred feet, he reached the Arkansas Valley June 29, 1844. His journey eastward across the great Kansas plains was of an easy character, and the 31st of July, 1844, saw his expedition safe at Independence, Mo. He had been absent fourteen months, during which time he had travelled some six thousand five hundred miles, the greater part of his journey being through the most barren and inhospitable regions of North America.
