8 to 12 June that year but failed to do so and stepped down, partly because he feared that as Prime Minister, he would fall out with his close friend, the King (as his predecessors had done). Devonshire then continued as First Lord and Prime Minister for almost another two weeks, and Newcastle returned a week later. Lord Waldegrave was awarded the Garter soon after and retired from public life upon the accession of George III in 1760. He died of smallpox three years later and lacking male heirs, his titles passed to his younger brother, John. After his death, his widow Maria married into the British Royal Family becoming the wife of Prince William Henry, Duke of Gloucester and Edinburgh, King George III's brother. Waldegrave's memoirs were published in 1821. Note: Lord Waldegrave is not usually counted as Prime Minister, but as he was First Lord of the Treasury he is sometimes regarded as the second-shortest-serving Prime Minister in British history.
