Early killings was lynched in 1889 by wealthy ranchers who accused her of cattle rustling, a charge that was later shown to be false. On July 20, 1889, a range detective from the WSGA named George Henderson accused Ella Watson (better known as
Cattle Kate), a local rancher, of stealing cattle from WSGA rancher by the name of Albert John Bothwell. The cattlemen sent riders to seize Watson before capturing her husband Jim Averell as well. Both of them were subsequently hanged near the
Sweetwater River. This gruesome act was one of the rare cases in the Old West in which a woman was lynched, an event that appalled many Wyoming residents County Sheriff Frank Hadsell arrested six men for the lynching and a trial date was set. However, before the trial, threats were sent to the witnesses who were to testify against the aggressors. One of those witnesses was young Gene Crowder, who mysteriously disappeared under unknown circumstances before the trial. Another, Averell's nephew and foreman Frank Buchanan, disappeared from the county as well after a shootout with unknown suspects, and was presumed to be hiding or murdered. Ralph Cole, another nephew of Averell's, died on the day of the trial from poisoning. A friend of Waggoner named Jimmy the Butcher, who was once arrested for rustling cattle belonging to the Standard Cattle Company, was also murdered. Range detective Tom Smith killed a suspected rustler, and when he was indicted for murder, political connections to the WSGA secured his release. These killings precipitated more hostilities and violence in the years to come. The next individual to be targeted was a former cowboy named
Nate Champion. On the morning of November 1, 1891, Champion and another man, named Ross Gilbertson, were sleeping in a cabin near the Middle Fork of the Powder River when a group of armed men went inside. Only two were able to fit into the small cabin while four others stood by outside. Champion was immediately awakened by the intrusion, and as the gunmen pointed their weapons at him, Champion reached for his own pistol hidden under a pillow and a shootout commenced. Champion successfully shot two of the gunmen, mortally wounding and killing assassin Billy Lykins. The rest of the assassination squad subsequently fled. Champion was left uninjured except for some facial burns from gunpowder. In a subsequent investigation of the attack, the names of those involved were leaked to two ranchers: John A. Tisdale and Orley "Ranger" Jones. However, both men were ambushed and murdered while they were riding, which outraged many of the small ranchers and farmers in the state. Led by a John R. Smith, Joe Debarthe, and Nate Champion, the group aimed to foster competition and challenge the grip of the WSGA on the Wyoming economy. Upon hearing this, members of the WSGA immediately viewed it as a threat to their hold on the stock interests. They then blacklisted members of the NWFSGA from the round-ups in order to stop their operations. However, the NWFSGA refused the orders to disband and instead publicly announced their plans to hold their own round-up on May 1, a month before the WSGA's. According to researcher
Levette J. Davidson, this act became the "last straw" that inspired the WSGA to commit fully to armed violence. In March 1892, the cattlemen sent agents to Texas from Cheyenne and Idaho to recruit gunmen and finally carry out their plans for exterminating the homesteaders. This group became known as the "Invaders". While on horseback, Canton and the gunmen traveled ahead while the party of WSGA officials led by Wolcott followed a safe distance behind.
Gunfight at the KC Ranch The first target of the WSGA was Nate Champion, who was at the KC Ranch at that time. They were tasked to perform the assassination that others had failed to carry out five months before. The group traveled to the ranch late Friday, April 8, 1892, quietly surrounded the buildings, and waited for daybreak. As the siege dragged on, a settler rode off to
Fort McKinney requesting to borrow a cannon but was turned down. A blacksmith named Rap Brown tried to build his own cannon, but it exploded upon first testing. He then built a
siege engine that the posse referred to as a "go-devil' or "ark of safety" - a large, bullet-resistant wagon that would help the settlers get close to the ranch so they could throw dynamite at the Invaders. Fortunately for the Invaders, one of their members, Mike Shonsey, managed to slip from the barn and was able to contact Governor Barber the next day. Frantic efforts to save the WSGA group ensued, and two days into the siege, late on the night of April 12, 1892, Governor Barber telegraphed
President Benjamin Harrison a plea for help. For unknown reasons, the telegram failed to reach President Harrison, so Wyoming senators
Joseph M. Carey and
Francis E. Warren visited the
White House in person and woke the President, informing him of the increasingly dangerous "insurrection" in Johnson County. Harrison immediately ordered the
U.S. Secretary of War Stephen B. Elkins to address the situation under
Article IV, Section 4, Clause 2 of the
U.S. Constitution, which allows for the use of U.S. forces under the president's orders for "protection from invasion and domestic violence". The
Sixth Cavalry from Fort McKinney near Buffalo, Wyoming, was ordered to proceed to the TA Ranch at once and take the WSGA expedition into custody. The Sixth Cavalry left Fort McKinney a few hours later at 2:00 on the morning of April 13 and reached the TA Ranch at 6:45 A.M. Colonel J.J. Van Horn, the officer in charge of the unit, negotiated with Sheriff Angus to lift the siege, and in return the Invaders were to be handed to civilian authorities. The Sixth Cavalry took possession of Wolcott and 45 other men with 45 rifles, 41 revolvers and some 5,000 rounds of ammunition, before escorting them first to Fort McKinney and then to Cheyenne. The text of Barber's telegram to the President was printed on the front page of
The New York Times on April 14, and a first-hand account of the siege at the T.A. appeared in
The Times and the
Chicago Herald and other papers. ==Arrest and legal action==
