With the Colorado National Guard acting on behalf of the employers alongside the strike breakers of the Baldwin-Felts Detective Agency, the United Mine Workers of America decided to arm its members and following the massacre, when the Guard machine gunned a miners camp killing women and children, the striking miners launched a ten day guerilla war before the Federal government stepped in disarming both sides.
Wargaming the Coalfield War could be quite simple exercise. Miners could be represented with a mix of suitable Old West and Victorian working class types as could the mine guards. The National Guard seem to have a mix of doughboy and cowboy hats and a number of manufacturers produce Pershing Expedition miniatures which could be used. The addition of homemade armoured vehicles (such as the Guard's 'Death Car' pictured above) would add an interesting element.
