- On September 2, 1885, a group of white coal miners attacked and killed 28 of their Chinese coworkers, wounded 15 others, and torched 79 of their homes in Rock Springs. None of the perpetrators—who had been angered by the refusal of Chinese miners to join in a strike for better wages, and by the Union Pacific Coal Company’s decision to allow the Chinese to work a lucrative part of the mine—were ever convicted for the brutal massacre.
