Summary
When the United States entered World War I in 1917, Pittsburgh was a city of immigrants, but they threw their support into the war effort united as Americans. Pittsburgh and Allegheny County produced half of the steel and much of… the munitions used by the Allies. Sixty thousand men went to war, women served on the front lines as nurses, and the city's large Red Cross provided support on the homefront. 2013
