On Saturday night when they went to town, these men couldn't stay in hotels or eat in restaurants. I'm not sure if they could drink and play cards in the saloons, but during the workweek, their skill with a horse, a rope and a gun, could gain them a level of respect.
Deputy Marshal Bass Reeves grew famous in the late 19th Century, during his 30-years pursuing and arresting bandits and murders throughout what was called Indian Territory. The former slave has some distinct resemblances to Lone Ranger of radio, comic book, TV and movies.
Bass was born a slave in Arkansas in 1883, and was taken to Texas his owner William Reeves as an 8-year-old boy. When the Civil War broke out, Reeves' son joined the Confederate Army and took Bass with him to the front lines as a servant.

“Right after the Civil War, being a cowboy was one of the few jobs open to men of color who wanted to not serve as elevator operators or delivery boys or other similar occupations,” says William Loren Katz, a scholar of African-American history.
The Choctaw, Creek, Seminole, Cherokee, and Chickasaw tribes had been forcibly moved from their homelands to "Indian Territory" where they governed themselves, but the federal government was responsible for rounding up the lawless element hiding out there, thousands of thieves, murderers and fugitives.
The call went out to hire 200 deputies for the job, and Bass Reeves fit the profile. Strong, steady, 6-foot-2, with a deep voice and commanding presence, he was appointed the first African-American lawman west of the Mississippi.

True to the mythical code of the West, Bass Reeves never drew his gun first. Though many outlaws aimed to shoot him, their bullets always missed. He was never even grazed by a bullet. Reeves admitted he shot and killed 14 men, but all in self-defense.
He's credited with bringing in 3,000 outlaws alive. More than once, showing up at the District Courthouse in Fort Smith with ten or more prisoners in tow.
From the “Court Notes” of the July 31, 1885, Fort Smith Weekly Elevator: “Deputy Bass Reeves came in same evening with eleven prisoners, as follows: Thomas Post, one Walaska, and Wm. Gibson, assault with intent to kill; Arthur Copiah, Abe Lincoln, Miss Adeline Grayson and Sally Copiah, alias Long Sally, introducing whiskey in Indian country; J.F. Adams, Jake Island, Andy Alton and one Smith, larceny.”
Though he couldn't read or write, Bass Reeves always knew which arrest warrant matched his man, and he used his brains, as well as his brawn and firepower to enforce the law. He often wore disguises to catch criminals unaware, and that may be the first clue that connected Bass with the famous "masked man."
He rode a large light gray horse and gave out silver dollars as a calling card, similar to the Lone Ranger's trademark silver bullets.
At least one biographer says the deputy marshal at times worked with a Native American partner tracking criminals. And like the Lone Ranger, he demonstrated an unshakable moral compass, even arresting his own son on a murder charge, after which the son was convicted and sentenced to life in prison.

A children's biography Bad News for Outlaws: The Remarkable Life of Bass Reeves, Deputy U.S. Marshal, won the 2010 Coretta Scott King Award. It was written by Vaunda Micheaux Nelson and illustrated by R. Gregory Christie.
One reviewer on Goodreads says, "This is a children's book, but still very informative." Because, of course, most children's books are not informative. (heavy sigh)
