For aficionados of the Wild West, there are few personalities as loved or as romanticized as Billy the Kid. Born as Henry McCarty in 1859, the future outlaw was in trouble with the law from a young age. Then after a spell in jail as a teenager, he escaped and went on the run.
By sometime in 1877, McCarty had taken on the alias of William H. Bonney. And after killing a blacksmith in Arizona, he fled to New Mexico, where he hooked up with the Regulators. They were a group of cattle rustlers in the employ of John Tunstall, an English rancher. When Tunstall was then killed by rival gangs, it sparked a conflict known as the Lincoln County War.
