They had at one time driven the trappers entirely out of their country, having stolen their traps, and effectually prevented them from taking furs.

In the conflict, in which Kit Carson was wounded, the Indians had retired, though with loss, still victorious, carrying with them all their booty of stolen horses.

Most humiliating of all, they had, without firing a shot, captured all the animals of the garrison and the trappers at Fort Hall.

And it was most probable that they had robbed and murdered the two men who had been sent to fort Laramie.
The trappers were all burning to avenge these wrongs.

The thievish Blackfeet had made these assaults upon them entirely unprovoked.
