During the American Civil War, the Commonwealth of Pennsylvania played a critical role in the Union, providing a huge supply of military manpower, equipment, and leadership to the Federal government. The state raised over 360,000 soldiers for the Federal armies, and served as a major source of artillery guns, small arms, ammunition, armor for the new revolutionary style of ironclad types of gunboats for the rapidly expanding United States Navy, and food supplies. The Phoenixville Iron Company by itself produced well over 1,000 cannons, and the Frankford Arsenal was a major supply depot.
