Pennsylvania

Pennsylvania is a state in the United States. It was invaded by the Confederate army three times: in 1862 during the War of Secession; from 1914 to 1917 during the Great War; and from 1942 to 1943 during the Second Great War. The latter two invasions were repelled by US forces; the first led to the destruction of the Army of the Potomac, the fall of Philadelphia, the end of the War of Secession, and the international diplomatic recognition of the Confederate States.

Major cities in Pennsylvania include Philadelphia and Pittsburgh.
