Red white & army blue

the long version

"It's 1881, and a US Army unit led by Colonel Joseph Kindred, the military's most famous Indian fighter, has been ordered to move fifteen hundred Colorado Ute to a new reservation in Utah as retribution for the massacre of an Indian agent. When Colonel Kindred kills a beloved Ute sub-chief in a fit of rage, an investigation follows, and Kindred, a decorated Civil War veteran, faces the possibility of a court-martial and the end of his career. Eventually, the trial is ordered, and a former corporal, Hiram Marlow, must testify against his one-time superior--a task that forces the young man to recall events he'd rather forget and casts a shadow over his own future"--Publisher's description,
