Before reaching the Platte, five of Wyeth’s men deserted their companions, either from dissatisfaction with their leader, or because they had just begun to realize the hazard of the enterprise. Nat Wyeth, however, was of that stuff we so expressly name clear grit. There was no flinching about him, the Pacific was his objective, and he determined to arrive at his destination even if he marched alone. William Sublette’s party, which Wyeth had joined, encountered the vicissitudes common to a trip across the plains in that day; the only difference being that the New England men now faced these difficulties for the first time, whereas Sublette’s party was largely composed of experienced plainsmen. They followed the course of the Platte, seeing great herds of buffalo roaming at large, while they experienced the gnawings of hunger for want of fuel to cook the delicious humps, sirloins and joints, constantly paraded like the fruit of Tantalus before their greedy eyes. They found the streams turbulent and swift; the Black Hills, which the iron horse now so easily ascends, were infested with bears and rattlesnakes. Many of the party fell ill from the effects of drinking the brackish water of the Platte, Dr. Jacob Wyeth, brother of the captain and surgeon of the party, being unluckily of this number. Sublette, a French creole, and one of the pioneers that have preceded pony-express, telegraph, stagecoach and locomotive, in their onward march, had no fears of the rivalry of the New England men, and readily took them under his protection. Besides, they swelled his numbers by the addition of a score of good rifles, no inconsiderable acquisition when his valuable caravan entered the country of the treacherous Blackfeet, the thieving Crows, or warlike Nez Perces. The united bands arrived at Pierre’s Hole, the trading rendezvous, in July, where they embraced the first opportunity for repose since leaving the white settlements. At this place there was a further secession from Wyeth’s company, by which he was left with only eleven men, the remainder preferring to return home with Sublette. Petty grievances, a somewhat too arrogant demeanor on the part of the leader, and the conviction that the trip would prove a failure, caused these men to desert their companions when only a few hundred miles distant from the mouth of the Columbia. Before a final separation occurred, a severe battle took place between the whites and their Indian allies and the Blackfeet, by which Sublette lost seven of his own men killed and thirteen wounded. None of Wyeth’s men were injured in this fight, but a little later one of those who had separated from him was ambushed and killed by Blackfeet.
