| has gloss | eng: The Pleasant Valley War (also sometimes called the Tonto Basin Feud or Tonto Basin War) was an Arizona range war between two feuding families, the cattle-herding Grahams and the sheep-herding Tewksburys. Although Pleasant Valley is physically located in Gila County, Arizona, many of the events in the feud took place in Apache County, Arizona, and in Navajo County, Arizona. The feud itself lasted for almost a decade, with its most deadly incidents between 1886 and 1887, with the last known killing occurring in 1892. At one stage, outsider and known assassin Tom Horn was known to have taken part as a killer for hire, but it is unknown as to which side employed him, and both sides suffered several murders to which no suspect was ever identified. Of all the feuds that have taken place throughout American history, the Pleasant Valley War was the most costly, resulting in an almost complete annihilation of the two families involved. |
