When he was ready to go back to work, his employers sent him to Rock Creek Station, Nebraska, where he had light duties as a stock tender. The station was an important stage and Pony Express stop, owned by David McCanles. That summer the station was almost bankrupt and could not pay McCanles. Wild Bill had just arrived when an altercation took place. It happened on July 12, 1861.
McCanles, his cousin James Wood, and James Gordon came to the station to collect money owed him. After a short argument, Wild Bill shot and killed McCanles. He also wounded Woods and Gordon. Wellman finished Woods off by beating him with a hoe. They both ran after Gordon and killed him with a shotgun blast. A trial was held but it was a farce. Twelve-year-old Monroe McCanles, who witnessed the shootings, was not allowed to testify, nor was he allowed in the court room. Wild Bill and Wellman were acquitted when the shootings were considered self defense.
Four years later, Colonel George Ward Nichols wrote about the event, and he didn't care if he got the details right. This was the start of his gunfighter legend. Nichols wrote that there was a "McCanles gang." He wrote that Wild Bill held off and killed ten men, in a one-sided fight. He also said Wild Bill was gravely wounded and had eleven bullets removed. None of it was true, but it made Wild Bill's reputation.
