 The situation in Rock Springs was stabilized as early as September 15, when Warren first requested the removal of federal troops, but the mines at Rock Springs remained closed for a time.On September 30, 1885, white miners, mostly Finnish immigrants who were members of the Knights of Labor, walked out of mines in Carbon County, Wyoming, in protest of the company's continued use of Chinese miners.In Rock Springs, the white miners were not back at work in late September, because the company still used Chinese labor.
