In July 1857, the first major battle between the U.S. Army and the Cheyenne Indians took place in present-day northwest Kansas. Resplendent in war finery, the Cheyennes had formed a grand line of battle such as was never again seen in Plains Indians wars. But they had never seen sabres before, and when the cavalry charged, sabres drawn, they panicked. William Y. Chalfant re-creates the human dimensions of a battle that was as much a clash of cultures as it was a clash of the U.S. cavalry and Cheyenne warriors.
