U.S.S. Constellation

U.S.S. Constellation, 1914. The Constellation sloop-of-war was the last sail-only warship designed and built by the United States Navy. She was built between 1853 and 1855, and was assigned as the flagship of the Africa Squadron, where she served with the African Slave Trade Patrol. During the American Civil War (1861-1865), the ship returned to the Mediterranean to patrol for Confederate vessels. She was later designated a National Historic Landmark. Creator: Unknown.
