In turbulent 1870s Texas, Ranger Leander McNelly led his men in one dramatic campaign after another, apprehending cattle thieves, desperadoes, border ruffians, and other dangerous criminals and throwing them in jail or—if necessary—six feet under. Telling a thrilling tale, the author of Tombstone recounts how McNelly's Rangers ventured across the border to retrieve stolen cattle—sparking the Las Cuevas War as they took on hundreds of Mexican troops with nothing but their Sharps rifles and six-guns.
