Elfego Baca was a gunfighter, law enforcement officer, lawyer, and politician in New Mexico, who became an American folk hero of the later years of the New Mexico Territory frontier. His goal in life was to be a peace officer, and for "the outlaws to hear [his] steps a block away". He is known for his involvement in an 1884 shootout in Frisco, New Mexico, as well as later fictionalized representations of his life in Westerns released during the mid-20th century.

A shootout, also called a firefight, gunfight, or gun battle, is a armed confrontation entailing firearms between armed parties using guns, always entailing intense disagreement(s) between the fighting parties. The term can be used to describe any such fight, though it is typically used in a non-military context or to describe combat situations primarily using firearms.
