This article details the Mountain Meadows Massacre, a horrific event that occurred from September 7–11, 1857, in the southern Utah Territory. It describes how Mormon settlers, organized as the Nauvoo Legion militia, aided by some Southern Paiute Native Americans, perpetrated the mass murder of 120–140 members of the Baker–Fancher wagon train, an immigrant group from Arkansas bound for California. The massacre was preceded by a five-day siege following an initial attack, culminating in a deceptive surrender where all adults and older children were killed, with only seventeen young children spared.
The article explores the complex historical context, attributing the massacre to a potent mix of war hysteria surrounding the Utah War, strident anti-outsider teachings during the Mormon Reformation, and the potential, though debated, instigation from senior LDS Church leadership, including Brigham Young. It covers the subsequent investigations, the eventual conviction and execution of John D. Lee as the sole perpetrator, and the long-term impact, including the LDS Church's evolving acknowledgment of its members' role. Modern historians frequently classify the massacre as a significant act of domestic terrorism in U.S. history.
Summary of the Mountain Meadows Massacre
History (September 7–11, 1857):
Important Details: The Mountain Meadows Massacre was a series of attacks during the Utah War. It involved Mormon settlers of the Nauvoo Legion militia and Southern Paiute Native American auxiliaries against the Baker–Fancher wagon train, mostly immigrant families from Arkansas bound for California.
Key Takeaways: The event resulted in the mass murder of at least 120 members of the wagon train, with only seventeen young children (ages six and under) spared. The motives included war hysteria, strident Mormon teachings against outsiders, and possible instigation from senior Mormon leadership.
Baker–Fancher Party (Early 1857):
Important Details: The party was formed mainly from families in northwestern Arkansas, led by "Colonel" Alexander Fancher. They were prosperous, well-organized, and wealthy, planning to restock supplies in Salt Lake City.
Key Takeaways: This was a typical, well-equipped emigrant train traveling through the Utah Territory.
Interactions with Mormon Settlers (August 1857):
Important Details: Amidst the Utah War and Brigham Young's declaration of martial law, the Baker–Fancher party was refused provisions in Salt Lake City. Rumors spread about their supposed misdeeds, including poisoning a spring, which historians attribute to general distrust and jealousy of the party's wealth.
Key Takeaways: The context of war and anti-outsider sentiment created a hostile environment for the emigrants.
Conspiracy and Siege (September 6–10, 1857):
Important Details: Local Mormon militia leaders in Cedar City and Parowan, including Isaac C. Haight and John D. Lee, planned an attack. An initial assault on September 7, with militiamen disguised as Native Americans, led to a five-day siege where the wagon train defended itself. Seven immigrants were killed and sixteen wounded in the opening attack.
Key Takeaways: The attack was premeditated, involved deception, and the besieged emigrants faced dwindling supplies and ammunition. Fear among the militia that their true identity was known escalated the situation.
Killings and Aftermath (September 11, 1857):
Important Details: John D. Lee, under a white flag, offered the beleaguered emigrants safe passage in exchange for their weapons and livestock. Once disarmed and separated (men from women and children), the emigrants were ambushed and killed by militiamen and auxiliaries. An 18th child, a girl aged 10-12, was killed for being "too big and could tell." The remaining 17 children were taken in by local Mormon families.
Key Takeaways: The massacre was carried out through an act of extreme betrayal. A cover-up was initiated, blaming Native Americans. Brigham Young's letter, instructing settlers not to interfere, arrived two days after the massacre. The victims' possessions were distributed or auctioned off.
Investigations and Prosecutions (1857–1877):
Important Details: Early Mormon investigations (Brigham Young) blamed Native Americans. Federal investigations (James Carleton, Jacob Forney) in 1859 revealed Mormon involvement, leading to the burial of remains and erection of a monument. Nine individuals were indicted in 1874.
Key Takeaways: John D. Lee was the only perpetrator tried and convicted. After two trials, he was executed by firing squad on March 23, 1877, claiming he was a scapegoat. Brigham Young excommunicated some participants but stated Lee's atonement was insufficient.
Criticism and Analysis (Ongoing):
Important Details: The massacre received extensive media coverage since 1857, intensifying after 1872. The LDS Church initially denied Mormon involvement but, after irrefutable evidence in 1999, recognized its members' responsibility and expressed "profound regret" in 2007, though not an apology. It is now widely considered the largest act of domestic terrorism in US history before the 1995 Oklahoma City bombing.
Key Takeaways: Historians attribute the massacre to strident Mormon teachings during the Mormon Reformation (including a "vengeance oath" and persecution complex), pervasive war hysteria due to the Utah War, and Brigham Young's inflammatory rhetoric. The debate continues regarding Young's direct knowledge or instigation.
Remembrances (1859–Present):
Important Details: The first monument was built by the U.S. Army in 1859 (later destroyed and replaced). Modern monuments were established in 1990 by the Mountain Meadows Association and in 1999 by the LDS Church. Forensic evidence from 1999 confirmed close-range firearm deaths for males and blunt force trauma for women and children.
Key Takeaways: The site was designated a National Historic Landmark in 2011, and ceremonies continue to remember the victims and acknowledge the tragedy.
