In Homestead, mysteries persist 113 years after bloody steel strike - By Moustafa Ayad, Pittsburgh Post-Gazette
On July 6, 1892, the Amalgamated Association of Iron & Steel Workers union and Pittsburgh steel magnate and philanthropist Henry Clay Frick clashed in Homestead over a lockout and cut in wages for Carnegie Steel Co. workers.
The showdown between Frick's hired guns from the Pinkerton Detective Agency and steel workers resulted in seven dead workers and three dead Pinkertons.
The aftermath of the lockout left Pittsburgh without organized labor for decades.
The lives lost on both sides are stark examples of how far the labor movement has come.
