On September 3, 1814, following the Burning of Washington and the Raid on Alexandria, Francis Scott Key and John Stuart Skinner set sail from Baltimore aboard the ship HMS Minden, flying a flag of truce on a mission approved by President James Madison. Their objective was to secure an exchange of prisoners, one of whom was William Beanes, the elderly and popular town physician of Upper Marlboro and a friend of Key’s who had been captured in his home. Beanes was accused of aiding the arrest of British soldiers. Key and Skinner boarded the British flagship HMS Tonnant on September 7 and spoke with Major General Robert Ross and Vice Admiral Alexander Cochrane over dinner while the two officers discussed war plans. At first, Ross and Cochrane refused to release Beanes but relented after Key and Skinner showed them letters written by wounded British prisoners praising Beanes and other Americans for their kind treatment.
