The following is from the book, Indian Wars, by Bill Yenne.
The Hualapai War continued into the winter, with search and destroy sweeps into the mountains of western Arizona. Major combat occurred on November 7, 1867, and on January 14, 1868. In the former incident, elements of the 8th Cavalry and the 14th Infantry Regiment attacked a Hualapai village, killing nineteen and capturing seventeen women and children. In the latter, an 8th Cavalry patrol out of Fort Mojave stumbled across a Hualapai encampment in Difficult Canyon. In the ensuing fire-fight, twenty-one Hualapai were killed. In another fight on march 21, the casualty figures were more evenly balanced. A 14th Infantry Regiment contingent escorting a mail train was ambushed by an estimated seventy-five Hualapai, and the battle left two dead on each side.
