Even after WWI had ended, the region of Arizona, New Mexico, and West Texas stubbornly refused to be tamed. It was still a place where frontier gunfights still broke out at an alarming rate. Utilizing official records, newspaper accounts, and oral histories, Cowboys and Gangsters tells the story of the untamed “Wild West” of the Prohibition-era of the 1920s and early 1930s and introduces a rogues’ gallery of sixgun-packing western gunfighters and lawmen. Told through the lens of the accounts of a handful of Texas Rangers and Federal Agents, this book covers a unique and action-packed era in American history. It’s a story that connects the horse and saddle days of the Old West, with the high-octane decade of the Roaring Twenties.

In January of 1920, the Eighteenth Amendment to the United States Constitution went into effect and the sale and manufacture of intoxicating spirits was outlawed. America had officially gone “dry.” For the next thirteen years, bootleggers and big city gangsters satisfied the country’s thirst with moonshine and contraband alcohol. On the US-Mexico border, a steady stream of black market booze flowed across the Rio Grande. Tasked with combating the liquor trade in the borderlands of the American Southwest were the “line riders” of the United States Customs Service and their colleagues in the Immigration Border Patrol. From late-night shootouts on the Rio Grande and the back alleys of El Paso, Texas, to long-range horseback pursuits across the deserts of Arizona, this book tells the little-known story of the long and deadly “liquor war” on the border during the 1920s and 1930s and highlights the evolution of the Border Patrol amidst the chaos of Prohibition. Spanning a nearly twenty-year period, from the end of World War I to repeal of the Eighteenth Amendment and beyond, The Line Riders reveals an often overlooked and violent chapter in American history and introduces the officers that guarded the international boundary when the West was still wild.
