The historical Slaughter was actually born in Sabine Parish in western Louisiana and spent most of his career as a sheriff, state representative, and cattleman in Cochise County in southern Arizona, where he died in 1922, having created the large San Bernardino Ranch, which in 1964 was declared a National Historic Landmark. Slaughter earlier served in the Confederate Army and was a Texas Ranger in San Antonio. After the war, Slaughter and his brothers engaged in cattle partnerships and drove herds from Texas into New Mexico, Kansas, California, and Mexico, having collected "strays" along the way. Some sources indicate that the real Slaughter spent more time playing poker than he did raising cattle or in the pursuit of the lawless element. Dedicated to the game of chance, he frequently beat the cattle king John Chisum at cards. In 1876, Slaughter was playing poker in San Antonio with cattle rustler Barney Gallagher and several other men when Slaughter noticed that Gallagher had marked cards and appeared ready to claim the pot. Suddenly, Slaughter grabbed the money, backed out the door, mounted his horse, and rode away. Gallagher pursued Slaughter to the Chisum ranch, where he informed the foreman that he had come to kill Slaughter. Instead Slaughter shot a hole in the heart of the surprised gambler. A fellow lawman described the short-in-stature Slaughter when in pursuit of outlaws as "a spider spinning its web for the unwary fly." A writer called Slaughter "the meanest good guy who ever lived."
