In 1855, the USS Constellation was commissioned. The ship, pictured above, patrolled near West Africa to search for ships that were possibly carrying human cargo. The ship also made the first Union Navy capture at sea during the Civil War. Today, the restored USS Constellation is afloat as a museum in the Inner Harbor.
