John G. Bourke won the Medal of Honor during the American Civil War.  He stayed in the army and graduated from West Point in 1869.  Between 1869 and 1883, Bourke served on the frontier with much of that time spent as an aide to General George Crook.  Bourke saw action in the Apache Wars and Great Sioux War.  He clashed with Sitting Bull, Crazy Horse, and Geronimo.  Bourke was a keen observer and chronicled his varied experiences.  He published them in 1892 under the title of "On the Border With Crook."  This book is a raw, insightful, and fascinating firsthand account of life in America's Old West.
