Many well-read students, historians, and loyal aficionados of Texas Ranger lore know the name of Texas Ranger Captain Frank Jones (1856-1893), who died on the Texas-Mexico border in a shootout with Mexican rustlers. In Six-Shooters and Shifting Sands, Bob Alexander has now penned the first full-length biography of this important nineteenth-century Texas Ranger. At an early age Frank Jones, a native Texan, would become a Frontier Battalion era Ranger. His enlistment with the Rangers coincided with their transition from Indian fighters to lawmen. While serving in the Frontier Battalion officers' corps of Company D, Frank Jones supervised three of the four "great" captains of that era: J.A. Brooks, John H. Rogers, and John R. Hughes. Besides Austin Ira Aten and his younger brothers Calvin Grant Aten and Edwin Dunlap Aten, Captain Jones also managed law enforcement activities of numerous other noteworthy Rangers, such as Philip Cuney "P.C." Baird, Benjamin Dennis Lindsey, Bazzell Lamar "Baz" Outlaw, J. Walter Durbin, Jim King, Frank Schmid, and Charley Fusselman, to name just a few. Frank Jones' law enforcing life was anything but boring. Not only would he find himself dodging bullets and returning fire, but those Rangers under his supervision would also experience gunplay. Of all the Texas Ranger companies, Company D contributed the highest number of on-duty deaths within Texas Ranger ranks.
