The Apache Expedition in the Sierra Madre [EPUB ebook] 

The Apache Campaign In The Sierra Madre is a first-hand historical account written by a captain in the United States Army, John Gregory Bourke. The book presents the details of the expedition led by General Crook to the Sierra Madre, in 1883. As Crook’s aide, Bourke had the opportunity to witness every facet of life in the Old West—the battles, wildlife, the internal squabbling among the military, the Indian Agency, settlers, and Native Americans, which are all presented in this read.
