The mountaineers who followed Sublette, took up their station in the woods on one side of the fort, and the Nez Perces, under Wyeth, on the opposite side, which accidental arrangement, though it was fatal to many of the Blackfeet in the fort, was also the occasion of loss to themselves by the cross-fire. The whites being constantly reinforced by fresh arrivals from the rendezvous, were soon able to silence the guns of the enemy, but they were not able to drive them from their fort, where they remained silent and sullen after their ammunition was exhausted.
Seeing that the women of the Nez Perces and Flatheads were gathering up sticks to set fire to their breastwork of logs, an old chief proclaimed in a loud voice from within, the startling intelligence that there were four hundred lodges of his people close at hand, who would soon be there to avenge their deaths, should the whites choose to reduce them to ashes. This harangue, delivered in the usual high-flown style of Indian oratory, either was not clearly understood, or was wrongly interpreted, and the impression got abroad that an attack was being made on the great encampment. This intelligence occasioned a diversion, and a division of forces; for while a small party was left to watch the fort, the rest galloped in hot haste to the rescue of the main camp. When they arrived, they found it had been a false alarm, but it was too late to return that night, and the several camps remained where they were until the next day.
Meantime the trappers left to guard the fort remained stationed within the wood all night, firmly believing they had their enemy "corraled," as the horsemen of the plains would say. On the return, in the morning, of their comrades from the main camp, they advanced cautiously up to the breastwork of logs, and behold! not a buffalo skin nor red blanket was to be seen! Through the crevices among the logs was seen an empty fort. On making this discovery there was much chagrin among the white trappers, and much lamentation among the Indian allies, who had abandoned the burning of the fort expressly to save for themselves the fine blankets and other goods of their hereditary foes.
From the reluctance displayed by the trappers, in the beginning of the battle, to engage with the Indians while under cover of the woods, it must not be inferred that they were lacking in courage. They were too well informed in Indian modes of warfare to venture recklessly into the den of death, which a savage ambush was quite sure to be. The very result which attended the impetuosity of their leaders, in the death of Sinclair and the wounding of Captain Sublette, proved them not over cautious.
On entering the fort, the dead bodies of ten Blackfeet were found, besides others dead outside the fort, and over thirty horses, some of which were recognized as those stolen from Sublette's night camp on the other side of the mountains, besides those abandoned by Fitzpatrick. Doubtless the rascals had followed his trail to Pierre's Hole, not thinking, however, to come upon so large a camp as they found at last. The savage garrison which had so cunningly contrived to elude the guard set upon them, carried off some of their wounded, and, perhaps, also some of their dead; for they acknowledged afterwards a much larger loss than appeared at the time. Besides Sinclair, there were five other white men killed, one half-breed, and seven Nez Perces. About the same number of whites and their Indian allies were wounded.
An instance of female devotion is recorded by Bonneville's historian as having occurred at this battle. On the morning following it, as the whites were exploring the thickets about the fort, they discovered a Blackfoot woman leaning silent and motionless against a tree. According to Mr. Irving, whose fine feeling for the sex would incline him to put faith in this bit of romance, "their surprise at her lingering here alone, to fall into the hands of her enemies, was dispelled when they saw the corpse of a warrior at her feet. Either she was so lost in grief as not to perceive their approach, or a proud spirit kept her silent and motionless. The Indians set up a yell on discovering her, and before the trappers could interfere, her mangled body fell upon the corpse which she had refused to abandon." This version is true in the main incidents, but untrue in the sentiment. The woman's leg had been broken by a ball, and she was unable to move from the spot where she leaned. When the trappers approached her, she stretched out her hands supplicatingly, crying out in a wailing voice, "kill me! kill me! O white men, kill me!"—but this the trappers had no disposition to do. While she was entreating them, and they refusing, a ball from some vengeful Nez Perce or Flathead put an end to her sufferings.
Still remembering the threats of the Blackfoot chief, that four hundred lodges of his brethren were advancing on the valley, all the companies returned to rendezvous, and remained for several days, to see whether an attack should take place. But if there had ever been any such intention on the part of the Blackfoot nation, the timely lesson bestowed on their advance guard had warned them to quit the neighborhood of the whites.
Captain Sublette's wound was dressed by Mr. Wyeth's physician, and although it hindered his departure for St. Louis for some time, it did not prevent his making his usual journey later in the season. It was as well, perhaps, that he did not set out earlier, for of a party of seven who started for St. Louis a few days after the battle, three were killed in Jackson's Hole, where they fell in with the four hundred warriors with whom the Blackfoot chief threatened the whites at the battle of Pierre's Hole. From the story of the four survivors who escaped and returned to camp, there could no longer be any doubt that the big village of the Blackfeet had actually been upon the trail of Capt. Sublette, expecting an easy victory when they should overtake him. How they were disappointed by the reception met with by the advance camp, has already been related.
