The Indians, when fighting, are prone to taunt and revile each other.  During one of the pauses of the battle, the voice of the Blackfeet chief was heard.

“So long,” said he, “as we had powder and ball, we fought you in the open field:  when those were spent, we retreated here to die with our women and children.  You may burn us in our fort; but, stay by our ashes, and you who are so hungry for fighting will soon have enough.  There are four hundred lodges of our brethren at hand.  They will soon be here—­their arms are strong—­their hearts are big—­they will avenge us!”

This speech was translated two or three times by Nez Perce and creole interpreters.  By the time it was rendered into English, the chief was made to say that four hundred lodges of his tribe were attacking the encampment at the other end of the valley.  Every one now was for hurrying to the defence of the rendezvous.  A party was left to keep watch upon the fort; the rest galloped off to the camp.  As night came on, the trappers drew out of the swamp, and remained about the skirts of the wood.  By morning, their companions returned from the rendezvous with the report that all was safe.  As the day opened, they ventured within the swamp and approached the fort.  All was silent.  They advanced up to it without opposition.  They entered:  it had been abandoned in the night, and the Blackfeet had effected their retreat, carrying off their wounded on litters made of branches, leaving bloody traces on the herbage.  The bodies of ten Indians were found within the fort; among them the one shot in the eye by Sublette.  The Blackfeet afterward reported that they had lost twenty-six warriors in this battle.  Thirty-two horses were likewise found killed; among them were some of those recently carried off from Sublette’s party, in the night; which showed that these were the very savages that had attacked him.  They proved to be an advance party of the main body of Blackfeet, which had been upon the trail of Sublette’s party.  Five white men and one halfbreed were killed, and several wounded.  Seven of the Nez Perces were also killed, and six wounded.  They had an old chief, who was reputed as invulnerable.  In the course of the action he was hit by a spent ball, and threw up blood; but his skin was unbroken.  His people were now fully convinced that he was proof against powder and ball.

A striking circumstance is related as having occurred the morning after the battle.  As some of the trappers and their Indian allies were approaching the fort through the woods, they beheld an Indian woman, of noble form and features, leaning against a tree.  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.  We have heard this anecdote discredited by one of the leaders who had been in the battle:  but the fact may have taken place without his seeing it, and been concealed from him.  It is an instance of female devotion, even to the death, which we are well disposed to believe and to record.
