One of the great lawmen of the Old West, Bob Paul (1830–1901) cast a giant shadow across the frontiers of California and Arizona Territory for nearly fifty years. Today he is remembered mainly for his friendship with Wyatt Earp and his involvement in the stirring events surrounding the famous 1881 gunfight near the OK Corral in Tombstone, Arizona. This long-overdue biography fills crucial gaps in Paul’s story and recounts a life of almost constant adventure. As told by veteran western historian John Boessenecker, this story is more than just a western shoot-’em-up, and it reveals Paul to be far more than a blood-and-thunder gunfighter. Beginning with Paul’s boyhood adventures as a whaler in the South Pacific, the author traces his journey to Gold Rush California, where he served respectively as constable, deputy sheriff, and sheriff in Calaveras County, and as Wells Fargo shotgun messenger and detective. Then, in the turbulent 1880s, Paul became sheriff of Pima County, Arizona, and a railroad detective for the Southern Pacific. In 1890 President Benjamin Harrison appointed him U.S. marshal of Arizona Territory. Transcending local history, Paul’s story provides an inside look into the rough-and-tumble world of frontier politics, electoral corruption, Mexican-U.S. relations, border security, vigilantism, and western justice. Moreover, issues that were important in Paul’s career—illegal immigration, smuggling on the Mexican border, youth gangs, racial discrimination, ethnic violence, and police-minority relations—are as relevant today as they were during his lifetime.

In 1854, the United States acquired the roughly 30,000-square-mile region of present-day southern Arizona and southwestern New Mexico from Mexico as part of the Gadsden Purchase. This new Southern Corridor was ideal for train routes from Texas to California, and soon tracks were laid for the Southern Pacific and Santa Fe rail lines. Shipping goods by train was more efficient, and for desperate outlaws and opportunistic lawmen, robbing trains was high-risk, high-reward. The Southern Corridor was the location of sixteen train robberies between 1883 and 1922. It was also the homebase of cowboy-turned-outlaw Black Jack Ketchum’s High Five Gang. Most of these desperadoes rode the rails to Arizona’s Cochise County on the US-Mexico border where locals and lawmen alike hid them from discovery. Both Wyatt Earp and Texas John Slaughter tried to clean them out, but it took the Arizona Rangers to finish the job. It was a time and place where posses were as likely to get arrested as the bandits. Some of the Rangers and some of Slaughter’s deputies were train robbers. When rewards were offered there were often so many claimants that only the lawyers came out ahead. Southwest Train Robberies chronicles the train heists throughout the region at the turn of the twentieth century, and the robbers who pulled off these train jobs with daring, deceit, and plain dumb luck! Many of these blundering outlaws escaped capture by baffling law enforcement. One outlaw crew had their own caboose, Number 44, and the railroad shipped them back and forth between Tucson and El Paso while they scouted locations. Legend says one gang disappeared into Colossal Cave to split the loot leaving the posse out front while they divided the cash and escaped out another entrance. The antics of these outlaws inspired Butch Cassidy and the Sundance Kid to blow up an express car and to run out guns blazing into the fire of a company of soldiers.
