Its population grew, and following the Civil War, the town boasted a mercantile store, saloon, blacksmith shop, cotton gin, and an elementary school.
Henry Hastings and Samuel McCracken, two brothers-in-law from Mississippi, were the town's first residents, settling the area "located on the Clear Fork of Sandies Creek" in 1857.
The name of the town came about from the return to the area of several members of the New Mexico Campaign, which had been led by General Henry Hopkins Sibley, following the civil war.
The killing occurred in October 1871 when Green, and a Private John Lackey, confronted Hardin at the mercantile store in Albuquerque with the intent to arrest him.
He was living at the McCracken boarding house, and found himself unarmed when approached by Hardin, having left his guns in his room while working on his invention at the blacksmith shop.
