It's a little more complicated than that. Fort Sumter sits in the harbor of Charleston, South Carolina. After the election of Abraham Lincoln, South Carolina seceded from the Union (the first to do so) and with six other states, created the Confederate States of America. Lincoln declared secession to be legally void, and maintained possession of federal property. Fort Sumter was a US fort; as such, it was a federal property. It was also inside the Confederacy. At the time that the "first battle of the Civil War" occurred at Fort Sumter, the fort was a "Union fort". The fort surrendered, however, and was held by the Confederacy throughout the duration of the war.
