Before his untimely death, Texas Jack became a legendary figure in the American Old West as a Western showman performing dramas on the stage throughout the country, and was immortalized in dime novels published around the world.

After a short time, he moved on to Texas, arriving at the Taylor Ranch near Brazos, where he began working as a cowboy participating in cattle drives, notably on the Chisholm Trail.

[4] In 1869, Texas Jack moved to Fort Hays, Kansas, where he met California Joe Milner and Wild Bill Hickok, the latter being sheriff of Ellis County at the time.

During the Battle of Summit Springs, Texas Jack captured his well-known white horse from Indian Chief Tall Bull.

[6] Texas Jack moved to Cottonwood Springs, Nebraska, where, aside from his work as a scout for the government, he made a lucrative living leading hunting expeditions for American and foreign parties, which were popular at the time.

[8] In 1876, Texas Jack led Sir John Rea Reid and his party on a hunt around the Bighorn Mountains and Sweetwater country.

[9] In December 1872, Omohundro and Cody debuted the first Wild West show, Scouts of the Prairie, in Chicago written and produced by Ned Buntline.

[14] Desiring a lighter tour schedule, Texas Jack parted ways with Cody, and in 1877, he formed his own acting troupe in St. Louis, known as the Texas Jack Combination featuring Morlacchi, Arizona John Burke, Modoc War scout Donald McKay, trick-shot Maud Oswald, and several Sweetwater and Warm Spring Indians.

In the late 19th century, dime novels depicting frontier life were becoming common, and Texas Jack became a popular subject of these stories.

The dime novels, printed on inexpensive wood pulp paper and costing five to ten cents each, were published weekly or monthly.

[16] In 1900, Joel Chandler Harris wrote On the Wing of Occasions, a series for the Saturday Evening Post, that featured Texas Jack and the Confederate Secret Service in a fictional plot to kidnap President Lincoln.
