From my resources ( check my cited sources ), I have accumulated that the reason the white men and volunteers attacked the Shoshone, was because, some Shoshone kids, and white boys, ended up getting into a fight, and the end result was 2 Shoshoni dying, and 2 white kids dying. There was lots of arguments with the white men, and the Native Americans, because settlers wanted the land, that Native Americans were on. After the pioneers: Stole their land, killed Shoshone, and killed many animals, the tribes started stealing pioneer’s stuff, and raiding farmer’s farms for animals.
