June 30, 1892: "Henry Clay Frick discharged the entire labor force of 3800 workers at the Homestead works after they threatened to strike for higher wages. July 6: Three hundred Pinkerton men were engaged by millworkers in a pitched battle at the Homestead works after arriving via the Monongahela River on two barges; 16 men were killed and many more wounded". The Pinkerton forces were quickly overcome by the steel workers, and the barge on which they arrived was ruined by fire. The state militia eventually suppressed the strikers.
