When police in Pittsburgh refused to put down the protests out of solidarity with the strikers, the governor called out the state militia who killed twenty strikers with bayonets and rifle fire. A month of chaos erupted. Strikers set fire to the Pittsburgh rail yards, destroying dozens of buildings, over a hundred locomotives, and over a thousand cars.
I found that even the Pittsburgh police didn't want to put down the protests. So, they had to call in a militia that killed 20 strikers and instead of decreasing the severity it instead erupted into a month of destruction because of the militias rifle fire and their bayonets.
