The Knights of Labor, which had organized the mechanics and transportation workers at Homestead, agreed to walk out alongside the skilled workers of the AA. Workers at Carnegie plants in Pittsburgh, Duquesne, Union Mills and Beaver Falls struck in sympathy the same day. The Declaration of the Strike Committee, dated July 20, 1892 reads in part, The employees in the mill of Messrs.
