election having taken place on 27 October. Later life As part of Navy Week in 1933 on 5 August, Dewar was invited to open a naval paintings exhibition at the Ilford Galleries in London. He took the opportunity to praise the Washington Naval Conference and the London Naval Conference 1930, and to criticise the size of the Treaty battleship. On the retired list of the Royal Navy, he was promoted to the rank of vice-admiral (retd.) on 31 July 1934. In early 1939, Dewar's memoirs were published. In The Navy from Within, he recounted his life story, while at the same time criticising severely the manner in which the Royal Navy trained its officers, blaming defects in said training for the naval failure at Gallipoli. However, his account was criticised as being far too harsh and at points hypocritical, for after condemning the naval system of training he then made many mentions of naval officers whom he himself considered to be excellent. In a letter to The Times, Dewar complained that their reviewer was taking far too much issue with the author, which as the reviewer pointed out, "a review of an autobiography must necessarily deal largely with the author himself". Responding to a review of The Navy from Within in The Naval Review which questioned the prominence of "The Royal Oak Affair" in the book, Dewar responded by stating; Dewar, despite the attached stigma of the mutiny and criticism of his memoirs, was still held in high regard by many, and as war approached he wrote a number of letters to The Times criticising the cost of the Air Raid Precautions network, which attracted much support in the "Letters" pages in that newspaper. During the Second World War, he returned to the Admiralty, working under his brother Alfred in the Historical Section of the Training and Staff Duties Division. After the war ended, Dewar would win one final victory when he sued the author and publisher of a book on Admiral Keyes for libel in 1953. In the book written by Brigadier-General Aspinall Oglander was a letter from Keyes to the King's private secretary, Lord Stamfordham, in which Keyes accused Dewar of having made contact with the press in his defence. Dewar denied this and the High Court of Justice agreed with him, finding in his favour. The solicitors acting on behalf of Aspinall-Oglander and the publishers, Hogarth Press
