Jim French, Frank McNab and other employees and friends of Tunstall's went to the Lincoln County Justice of the Peace, "Squire" John Wilson. He proved sympathetic to their cause and swore them all in as special constables to bring in Tunstall's killers. This posse was legal and led by Richard "Dick" Brewer, a respected local rancher who had worked as Tunstall's foreman. The newly minted lawmen dubbed themselves The Regulators and went first in search of Deputies Evans, Morton, Hill, and Baker and all the others implicated in Tunstall's death. Thus, two groups of lawmen rode throughout Lincoln County at war with each other. The Regulators tracked down and arrested Deputies Morton and Baker on March 6. In what may or may not have been a calculated revenge killing, both Deputies were killed soon after, officially while attempting to escape. After returning to Lincoln, the Regulators further claimed that Deputies Norton and Baker had also killed McCloskey of the Regulators. Meanwhile, Lincoln County Deputies Jesse Evans and Tom Hill were rustling sheep during which Hill was killed and Evans was wounded by the sheep farmer. Several other revenge killings, committed by both the Regulators and the gunmen hired by Murphy-Dolan, soon followed. On April Fool's Day 1878, the Regulators ambushed and fatally shot Lincoln County Sheriff William Brady and Deputy, George Hindemann. Half a dozen Regulators, including Bonney, Jim French, and Frank McNab, carried out the revenge killings. The Regulators killed Buckshot Roberts at Blazer's Mills, southwest of Lincoln in area now within the Mescalero Apache Reservation. Their man, Richard Brewer, also died in this shootout. The period of July 15 through July 19, 1878, Battle of Lincoln, became known as "The Five-Day Battle." The U.S. Army from nearby Fort Stanton, under the command of Colonel Nathan Dudley, intervened in the fight and defeated the Regulators. Dudley threatened the Regulators while the Dolanites strutted along Lincoln's street. A new federal law of 1878, passed by a Democratic majority of Congress and in reaction to the former use of military forces in southern states to suppress violence targeting freedmen during the Reconstruction era, prohibited the Army from intervening in civilian conflicts. After their loss to the Dolan forces in the Five-Day Battle, the Regulators and their supporters quickly left town. Bonney remained in New Mexico, moving to Fort Sumner, New Mexico, 160 miles west of the Texas Panhandle, on the Pecos
