Record of Engagements with Hostile Indians
... Some of us stayed back to watch the enemies. I looked one way and saw strange Indians....
I rode closer. Eeh! Crows! A new tribe fighting Chief Joseph. Many snows the Crows had been our friends. But now, like the Bitterroot Salish [Flatheads], turned enemies.
My heart was just like fire.
Sturgis's worn-out cavalry dragged along, well behind the Crow scouts.
When we reached the more level country at the top of the pass, our allies were nowhere to be seen, but we could hear the sound of distant firing, and passed several dead bodies along the trail, all of them those of the enemy

The approach of night found my command scattered for ten miles, and fully one-third on foot; and I was thus forced to go into camp after a weary march of 37 miles. Captain Bendire's detachment (of General Howard's command) did not arrive in camp until late at night, with every officer and man on foot. This detachment was so manifestly unable to continue further that I directed Captain Bendire to remain in camp next day to rest his animals, and afford his men an opportunity for securing some game (as they, as well as all the others, had been several days without rations) and then return to General Howard's command. With my own force I renewed the pursuit next morning.

Notice how the Crow Reservation has changed size over the years too.
