The Regulators head southwest from the area…

The Regulators head southwest from the area around Lincoln three days after the murders of Brady and Hindman, reaching Blazer's Mill, a sawmill and trading post that supplies beef to the Mescalero Apaches.

They come upon the rancher Buckshot Roberts, listed on their arrest warrant as one of Tunstall's murderers.

In the ensuing conflict, the Regulators mortally wound Roberts, but he manages to kill Brewer and wound a few others.
