Decatur's Medal, Front
Commodore Stephen Decatur, Jr (5 January 1779 – 22 March 1820) was an American naval officer notable for his heroism in the Barbary Wars and in the War of 1812. He was the youngest man to reach the rank of captain in the history of the United States Navy, and the first American celebrated as a national military hero who had not played a role in the American Revolution.
