The gunfight at the O.K. Corral was a gunfight that lasted less than a minute between lawmen led by Virgil Earp and members of a loosely organized group of outlaws called the Cowboys that occurred at about 3:00 p.m. on Wednesday, October 26, 1881, in Tombstone, Arizona Territory, United States. It is generally regarded as the most famous gunfight in the history of the American Old West.

Billy Claiborne was an American outlaw cowboy, drover, miner, and gunfighter in the American Old West. He killed James Hickey in a confrontation in a saloon, but it was ruled self-defense. He was present at the beginning of the Gunfight at the O.K. Corral, but was unarmed and ran from the shootout. Only a year later, while drunk, he confronted gunfighter "Buckskin" Frank Leslie and was killed.
