The following is a list of men in the Iron Military District of Utah Territory’s Nauvoo Legion militia whose names have been associated with the Mountain Meadows Massacre. The names have been gathered from a variety of sources including eyewitness accounts, arrest warrants and criminal indictments, and newspaper articles. A completely accurate list of those who participated in or witnessed the murders of the California-bound emigrants may be impossible to compile. Many of the participants kept silent about their roles. The testimonies of many witnesses were given fifteen years or more after the massacre. Those who admitted being at the massacre were usually careful not to incriminate themselves and their closest associates.
