First released in 1978 and still the best account of territorial law enforcement, this book presents a thoroughly researched, well-documented, and entertaining history of United States marshals in New Mexico and Arizona during the tumultuous territorial years. Included in the story are notable lawmen such as John Pratt, John E. Sherman, and Creighton M. Foraker and gunfighters like Billy the Kid, "Doc" Holliday, and the Earp Brothers. With detailed accounts of many other lesser-known lawmen and criminals, Ball gives a well-rounded history of the mundane as well as the spectacular incidents in the lives of these lawmen during the unstable territorial years.
