September 10, 1897
Striking immigrant anthracite coal miners raise an American flag and march on the still-open mine in Lattimer, Pennsylvania. They were met by the local sheriff and Coal and Iron Police deputies. The sheriff ordered the workers to disperse and the deputies opened fire, killing 19 and wounding as many as 49 others. All those killed in the Lattimer Massacre were shot in the back; the sheriff and 73 deputies were arrested, tried, and acquitted.
