Albert John Bothwell.
A self-important cattle baron of Wyoming, Albert John Bothwell was a leading instigator of the infamous Wyoming Johnson County War.
Born in Iowa around 1855, Bothwell moved to Wyoming as a young man and quickly became one of Sweetwater County’s most prosperous cattlemen. Described as arrogant, Bothwell had been freely grazing his cattle on unclaimed homestead land until James Averell and Ellen “Cattle Kate” Watson came along in 1886 and filed homestead claims on the property. Bothwell was so sure no one would claim the land that he even went so far as to fence much of it with barbwire illegally.
When Averell and his girlfriend, Ellen Watson, moved on to the land, Bothwell’s illegal use of the property led to repeated disputes between the couple and the large cattle baron. When Averell wrote to the Casper Daily Mail criticizing Bothwell and claiming that the cattle barons had too much power, Bothwell retaliated by claiming that Averell and Watson were stealing his cattle. Dubbing Watson “Cattle Kate,” he also accused her of being a prostitute who sometimes accepted stolen cattle in payment.
As the dispute raged over the next several months, Bothwell convinced other area ranchers of Averell and Watson’s guilt. On July 20, 1889, he, along with five other men, hanged the pair at a small canyon by the Sweetwater River. Though the men were charged with murder, key witnesses began to die or disappear mysteriously, and all of them were acquitted. Both Averell and “Cattle Kate” were “tried” in the press, owned or influenced by the cattle barons, and branded as “outlaws.” Bothwell later acquired both homesteads of the murdered victims.
Later investigations into the affair found that neither James Averell nor his girlfriend, Ellen “Cattle Kate” Watson, was likely guilty of any crime. Meanwhile, this event, along with several others, led to the Johnson County War in Wyoming.
