Killings and aftermath of the Mountain Meadows Massacre

The Mountain Meadows massacre was a series of attacks on the Baker–Fancher emigrant wagon train, at Mountain Meadows in southern Utah. The attacks culminated on September 11, 1857, in the mass slaughter of the emigrant party by the Iron County district of the Utah Territorial Militia and some local Indians.

Initially intended to be an Indian massacre, two men with leadership roles in local military, church and government organizations, Isaac C. Haight and John D. Lee, conspired for Lee to lead militiamen disguised as Native Americans along with a contingent of Paiute tribesmen in an attack. The emigrants fought back and a siege ensued. Intending to leave no witnesses of Mormon complicity in the siege and avoid reprisals complicating the Utah War, militiamen induced the emigrants to surrender and give up their weapons. After escorting the emigrants out of their fortification, the militiamen and their tribesmen auxiliaries executed approximately 120 women, children, and men. Seventeen younger children were spared.

Investigations, temporarily interrupted by the American Civil War, resulted in nine indictments during 1874. Of the men indicted, only John D. Lee was tried in a court of law. After two trials Lee was convicted and executed near the massacre site.
