N.O. Reynolds (1846-1922) has remained somewhat a mysterious figure, his Texas Ranger career being overshadowed by such names as Frank Hamer, Sam Walker, and Bill McDonald. Historians Chuck Parsons and Donaly E. Brice bring the life of Reynolds back to the prominence he deserves and present a complete picture of the man who brought a greater respect for the law in Central Texas.
Reynolds began as a sergeant in famed Company D, Frontier Battalion in 1874. He served honorably during the Mason County "Hoo Doo" War and was chosen to be part of Major John B. Jones's escort, riding the frontier line. In 1877 he arrested the Horrells, who were feuding with their neighbors, the Higgins party, thus ending their Lampasas County feud. Shortly thereafter he was given command of the newly formed Company E of Texas Rangers. Also in 1877 the notorious John Wesley Hardin was captured; N.O. Reynolds was given the responsibility to deliver Hardin to trial in Comanche, return him to a safe jail during his appeal, and then escort him safely to the Huntsville penitentiary. Even though mobs wanted to lynch Hardin, they were afraid to challenge N.O. Reynolds and his Rangers. Reynolds served as a Texas Ranger until he retired in 1879 at the rank of lieutenant, later serving as City Marshal of Lampasas and then County Sheriff of Lampasas County."
