Mountain Meadows Massacre - Southwestern Utah Madness

In early September 1857 a wagon train expedition of 140 people traveling from Arkansas stopped for camp at a spot called Mountain Meadows in Southwestern Utah. They were making their way to California. They wouldn't make it out of Mountain Meadows.
The emigrants were attacked by a group of Mormon Militia Men and a number of Paiute Natives, this attack turned into a siege that lasted days. The emigrants dug in and fought back. However, they were surrounded and eventually ran out of water. Most likely out of desperation the emigrants accepted the white flag of a truce offered by the Mormons and if they would give up their arms and some property they would be allowed to leave in peace and safety. Sounded like a plan. Except the Mormons deceived the group of Emigrants and instead of letting them leave, they slaughtered them.
And on September 11, 1857 having no weapons to protect themselves...the Mormon Militia separated the Emigrant Women and Children from the Men and then shot all the Men. Next, the Mormons beat the remaining Women and Children to death. Only 17 children survived out of a group of 140 people.
It wasn't until two years later that the US Army coming through the area discovered the scattered bones of the victims, burying what they could collect. And like many events of this nature, it has been kept quiet. Locally, I asked quite a few people who grew up in Southwestern Utah if they had been taught about the Massacre while in school, all of them said No.
