Blockade runners of the American Civil War

During the American Civil War, blockade runners were used to get supplies through the Union blockade of the Confederate States of America that extended some 3,500 miles (5,600 km) along the Atlantic and Gulf of Mexico coastlines and the lower Mississippi River. The Confederacy had little industrial capability and could not produce the quantity of arms and other supplies needed to fight against the Union.
