On the afternoon of October 26, 1881, nine men clashed in what would be known as the most famous shootout in American frontier history. Thirty bullets were exchanged in thirty seconds, killing three men and wounding three others. The fight sprang forth from a tense, hot summer. Cattle rustlers had been terrorizing the back country of Mexico and selling the livestock they stole to corrupt ranchers. The Mexican government built forts along the border to try to thwart American outlaws, while Arizona citizens became increasingly agitated. Rustlers, who became known as the cow-boys, began to kill each other as well as innocent citizens. That October, tensions boiled over with Ike and Billy Clanton, Tom and Frank McLaury, and Billy Claiborne confronting the Tombstone marshal, Virgil Earp, and the suddenly deputized Wyatt and Morgan Earp and shotgun-toting Doc Holliday.
