to the bottom of the statistical dispute, pointing out that while Lloyd George might not have "measured his language" in the debate, he regarded himself as being victim of "a wrong" (in that he had on 9 April, in good faith, presented to the House of Commons figures given to him, and that various different sets of figures had subsequently been produced from the War Office whilst elements in the military attempted to discredit him). In 1921, Maurice was one of the founders of the British Legion, and although he was not initially very active in the organization, he would later serve as the president from 1932 to 1947. In 1922 Maurice was appointed principal of the Working Men's College in London, an institution founded by his grandfather. He held this position until 1933. Cabinet Secretary Maurice Hankey had a low opinion of the military's disingenuous use of statistics and took pride in having assisted Lloyd George in preparing his speech of 9 May 1918. He may well have used his influence in 1925 to block Maurice from becoming Chichele Professor of the History of War at Oxford University (the post went to Ernest Swinton). However, Maurice was appointed Professor of Military Studies at the University of London in 1926, and taught both there and at Trinity College, Cambridge until the end of his life. In 1933 he became principal of East London College. In his memoirs in the mid 1930s Lloyd George was harsh about Maurice and did not come clean about his own disingenuous use of statistics in the debate (i.e. relying on the figures with which the military had supplied him on 9 April and 18 April, and ignoring the more accurate figures which the military had subsequently produced). During the Munich Crisis, Maurice volunteered the services of the Legion to the government. He flew to Berlin to meet Hitler for the formation of the short-lived British Legion Volunteer Police Force. Three days before war commenced on 1 September 1939, Maurice, as President of the British Legion, broadcast an appeal to Hitler urging him not to invade Poland, an action which John Grigg attributes to naivety. Maurice died on 19 May 1951, in Cambridge well cared for by his daughter, the economist Joan Robinson.
