During a gun war here between company and union miners, several boxes of dynamite were exploded on July 11, 1892, shattering a four-story mill. Overwhelmed by union miners, company managers surrendered. Six fatalities, half from each side, preceded four months of martial law and military occupation by a thousand soldiers. A long series of battles followed. Resumed in North Idaho in 1899, this conflict continued in Colorado, Montana, Nevada, and Arizona.
