Several significant Federal leaders hailed from the Commonwealth. Military leaders from Pennsylvania included Generals George G. Meade (the victorious commander at Gettysburg and from Philadelphia), Winfield S. Hancock, John F. Reynolds, Admiral David D. Porter, and Quartermaster General Montgomery C. Meigs. Pennsylvanians also rose to prominence as political figures during the war, like Secretary of War Simon Cameron and the fiery Radical Republican abolitionist Representative Thaddeus Stevens. A small number of Pennsylvanians joined the ranks of the Confederacy, including such leaders Generals John C. Pemberton and Josiah Gorgas.
