[7] In 1834 a band of trappers and traders led by Antonio Montero from Portugal built a trading post east of Kaycee WY.It became known as the “Portuguese Fort.” A unique site, what little remains from the area have been donated to the Hoofprints of the Past Museum and includes artefacts including a sword, beads, and clay pipes.

[8] The 1860s brought new attention from both whites and Native Americans to the northeast corner of what soon would become Wyoming Territory.

Mountain man Jim Bridger warned against establishing a trail through the Arapaho and Lakota hunting grounds, urging that another path west of the Bighorns be used instead.

Hole-in-the-Wall is located in the foothills of the Big Horn Mountains of Johnson County, Wyoming.

Cassidy, the Sundance Kid, and other desperados met at a log cabin in the Hole-in-the-Wall country which has been preserved at the Old Trail Town museum in Cody, Wyoming.

The large ranches, concerned about this practice, forbade their employees from owning cattle and aggressively defended against rustling.

The large companies began to aggressively appropriate land and control the flow and supply of water in this area; they justified these excesses on what was public land by using the catch-all allegation of rustling, and vigorously sought to exclude the smaller ranchers from participation in the annual roundup; apparently agents of the larger ranches killed several alleged rustlers.

In April 1892 the WSGA hired killers from Texas; an expedition of 50 men was organized, which proceeded by train from Cheyenne to Casper, Wyoming, then toward Johnson County, intending to eliminate alleged rustlers and also, apparently, to replace the government in Johnson County.

Two men, evidently trappers, who had taken shelter for the night, were captured as they emerged from the cabin early that morning to collect water at the nearby Powder River, while the third, Nick Ray, was shot while standing inside the doorway of the cabin and died a few hours later.

Two passers-by noticed the ruckus and rode to Buffalo, where Johnson County Sheriff William "Red" Angus raised a posse of 200 men and set out for the "KC Ranch".

During the siege, Champion kept a poignant journal which contained a number of notes he wrote to friends while taking cover inside the cabin.

With the house on fire, Nate Champion signed his journal entry and put it in his pocket before running from the back door with a six shooter in one hand and either a knife and a rifle in the other.

The killers pinned a note on Champion's bullet-riddled chest that read, "Cattle Thieves Beware."

Jack Flagg, who after escaping his pursuers, rode to Buffalo where he reported Champion's dilemma to the townsfolk.

Sheriff Angus then raised a posse of 200 men over the next 24 hours and set out for the KC on Sunday night, April 10.
