    Ascension - A British island located in the South Atlantic 700 miles northwest of St. Helena. During the exile of Napoleon, the Royal Navy built a station on Ascension. The island is the site of an international cable station; during World War II an airfield was built there for patrol flights and as a refueling stop for transatlantic flights to Africa, southern Europe, and the Middle East
