Luna County was formed from parts ofGrant County andDoña Ana County by theNew Mexico Legislature on March 16, 1901. It was named forSolomon Luna, a politician who advocated for independence of the county, following a strong rivalry between the cities ofDeming andSilver City, both of which were at the time in Grant County.[3]
Before dawn on March 16, 1916,Mexican revolutionaryPancho Villa led several hundred of hisrebel soldiers across the Mexican border into the village ofColumbus in the southern part of the county. The invaders raided and burned much of the town, causing many residents to flee to the desert. Although the raid took the town by surprise, it also awakened 350United States Army soldiers stationed at Camp Furlong at the edge of town. These soldiers defended Columbus with twomachine guns. The fighting continued until dawn, when Villa fled back across the Mexican border, five hours after the initial invasion and approximately ninety minutes after attacking the town. Despite theU.S. Army's subsequent "Mexican Expedition" into Mexico, Villa was never captured. The United States' involvement in World War I soon diverted attention away from the pursuit of Villa. He was assassinated seven years later. The raid resulted in the deaths of eighteen Columbus residents and U.S. soldiers, while approximately seventy-five of Villa's soldiers were killed.
