A good Autograph Letter Signed ‘Adolphus Frederick’, to "My dear Lord", referring to "The great success of the Armies of the Allies" and the possibility that the Duke will be required to go overseas, and therefore he is unable to accept his correspondent’s invitation.

Cambridge House, 9 November 1813. Adolphus Frederick, Duke of Cambridge (1774-1850), tenth child of King George III and Queen Charlotte. In 1816 the Duke of Cambridge, on behalf of King William IV, was appointed to the viceroyalty of Hanover, which at the treaty of Vienna (1814) had been elevated from an electorate to a kingdom. His discreet administration helped to preserve the Hanoverian crown for his family. On the death of King William IV, the throne of Hanover passed to the Duke of Cumberland. "The great success of the Armies of the Allies has so altered the Situation of Germany that it is very probable I may soon be ordered to leave this Country .".
