By the time the Lincoln County War in New Mexico began to brew in the mid 1870’s, Roberts, was running a small ranch in the Ruidoso Valley near Lincoln. Most accounts say that Roberts was a member of the Dolan-Murphy Faction, who were monopolizing the trade of the county until "upstarts” Alexander McSween and John Tunstall began to challenge their monopoly, ultimately leading to the Lincoln County War. Because Roberts sometimes worked for James Dolan and was a known friend of Lawrence Murphy, he was automatically associated with the Dolan Faction; however history tells us that he preferred to be alone, didn’t upset easily and was determined to have no part in the violence that began to erupt in the dispute for power in Lincoln County. When told he needed to choose his a side in the conflict, he curtly replied that he intended to take neither side; that he had seen fighting enough in his time, and would fight no man’s battle for him.

However, when John Tunstall was shot down by the Dolan-Murphy faction on February 18, 1878, it was automatically assumed that Roberts was a part of the group and a warrant was soon issued for his arrest. In response, Roberts put his ranch up for sale, planning on leaving the area for good. While staying at a friend’s home near Blazer’s Mill, his property sold and he waited eagerly for his check. In the meantime, Constable Dick Brewer formed the Regulators to search for Tunstall's murderers.

Roberts' payment was to be delivered to Blazer’s Mill and he checked often to see if it had arrived. When he spied a buckboard traveling toward the Mill on April 4, 1878, Roberts headed in that direction in hopes the ranch payment might be among the delivery. What Roberts didn’t know, was that the Regulators were at the Mill, with their horses hitched around back.

Buckshot Roberts Last Stand

In the next few minutes would occur one of the most remarkable gunfights that ever took place in the Old West, with Roberts fighting for his life against eight skilled gunslingers, and in the end, creating a frontier legend.

Blazer’s Mill was a sawmill and trading post, including a post office, located on the Rio Tularosa, with a number of other buildings, including a restaurant, scattered close by. As the Regulators, including Dick Brewer, Frank Coe, John Middleton, Doc Scurlock, Charles Bowdre, Henry Brown, Frank MacNab and Billy the Kid were eating in a nearby building, Roberts hitched his mule in front of the mill and went inside to see if his payment had been delivered.

The Regulators, who had just killed Sheriff William Brady three days earlier, sat casually eating when Frank Coe spied Roberts going into the mill. Coe soon approached Roberts attempting to talk him into surrendering. However, Roberts felt sure if he surrendered he would be killed by the vengeful Regulators and refused. Regulator leader, Dick Brewer soon became impatient with the stand-off and sent more men outside to take Roberts by force.

At the sight of the armed men, Roberts grabbed his rifle and fired, hitting Charlie Bowdre's belt buckle and knocking the wind out of him. Bowdre, on the other hand, was luckier, hitting Roberts in the abdomen. Though severely wounded, Roberts kept shooting as he retreated to the doorway of the mill, hitting John Middleton in the chest, striking "Doc” Scurlock’s pistol, hitting Frank Coe in the right hand taking off his thumb and trigger finger and grazing Billy the Kid's arm.

Finally, Roberts’ rifle was spent and Billy the Kid rushed the wounded man, only to be knocked senseless by the barrel of Roberts' rifle.
