March 28, 1878; Lincoln, Lincoln County, New Mexico Territory---The Regulators have been branded outlaws. Their leader, Dick Brewer, has had his legal authority stripped of him by the governor of New Mexico Territory himself, Sam Axtell. Ever since the Regulators killed Frank Baker, Billy Morton, and William McCloskey earlier in the month, they have been hiding out in the small Hispanic village of San Patricio. For some reason though, Brewer decides to return to Lincoln on this day, possibly just to scope out the current situation, just to know what's all going on. Billy Bonney, his deputy before all the Regulators were outlawed, decides to accompany him, possibly to satisfy his own curiosity of what's transpiring in Lincoln, possibly to act as a bodyguard for Brewer, or possibly to see if he can take down any more of Tunstall's killers.
Once in Lincoln, Deputies George 'Dad' Peppin and Billy Mathews, along with several others, approach Brewer and Billy in the open street and inform them that they have warrants for their arrests. The two Regulators laugh it off, but when Peppin and his men persist, Brewer and Billy pull their guns and fire a few shots at them. Though none of their shots hit anyone, it gets their point across and the deputies leave them alone for the rest of the day.
Later on in the day, Billy Bonney and Billy Mathews get into an altercation in the street. Bonney ends up letting his temper get the better of him, and pulls his gun. He fires a few shots at Mathews, who flees before he is hurt. A short time later, Billy and Brewer leave Lincoln and return to San Patricio.
