The famous gunfight at the O.K. Corral had its inception in the hold-up of a Sandy Bob Line Stage. After the death of Old Man Clanton, Marshal Earp thought he say a chance to split Clanton's outfit by tricking the outlaws into gunning each other down. Wyatt knew that if this failed there would have to be a fight to the finish between the John Law's of Tombstone and the Clanton outlaws.
