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.
