For Perry, the post-war years were marred by controversies. In 1815, he commanded "Java" in the Mediterranean during the Second Barbary War. While moored in Naples, Perry slapped the commander of the ship's Marines, Captain John Heath, whom Perry considered incompetent and insubordinate. The ensuing court-martial found both men guilty, but levied only mild reprimands. After the crew returned home, Heath challenged Perry to a pistol duel, which was fought on October 19, 1817, on the same field in Weehawken, New Jersey where Aaron Burr shot and killed Alexander Hamilton. Heath fired first and missed. Perry declined to return fire, satisfying the Marine's honor.
