buffalo daily, until we arrived at Tongue River, about the new moon of Leaf Fall. On our way we lost nearly three hundred head of horses, which were stolen by the Black Feet. We did not trouble ourselves to pursue them, as we felt confident they were but lent them, and that they would shortly be returned with good interest. At Tongue River we confederated with our friends, the Grovans, in an attack upon the Cheyenne village; from thence we returned to the Yellow Stone, when I detached a party of one hundred and sixty warriors on an excursion to the Black Foot village, and they returned bringing six hundred fine horses with them. We then passed on to Fort Cass, where we witnessed much dejection and gloom, occasioned by a serious reverse which they had experienced since our last visit.
