Captain John Gregory Bourke was the premier soldier-scholar of the American Indian Wars. Highly-educated, a Civil War veteran, and friend to General George Crook, this is Bourke’s classic work detailing Crook’s command in Arizona, Wyoming, and Montana. He was with Crook at the Rosebud fight and at MacKenzie’s last fight with the Cheyenne in 1876. One of the most fascinating memoirs of the Indian Wars.
