a letter in a Tombstone newspaper taunting Behan and his men). The federal posse ultimately killed four men, starting with Stilwell and ending with Brocius. About April 15 the Earps and some of their associates rode out of Arizona Territory, headed for New Mexico Territory. Background After a long-simmering feud and increasing animosity and threats, Tombstone town Marshal Virgil Earp, Assistant Town Marshal Morgan Earp, and temporary deputy marshals Wyatt Earp and Doc Holliday confronted outlaw Cowboys Billy Claiborne, Ike and Billy Clanton, and Tom and Frank McLaury in the Gunfight at the O.K.

McMaster and Johnson were known as tough men who knew how to use their guns. McMaster had seen service with the Texas Rangers in 1878–1879 when his unit captured and held Curly Bill Brocius prisoner for five months.
