After VE Day , Ismay accompanied Churchill to the Potsdam Conference . Like Yalta , the conference focussed primarily on political issues , so there was little for Ismay to do . After Clement Attlee defeated Churchill in the 1945 election , becoming Prime Minister , Ismay kept his position , working with Attlee at the conference , but remained loyal to Churchill . Ismay and Churchill remained friends for the remainder of their lives , and Ismay even helped Churchill write his memoirs , reviewing and commenting on each chapter of his manuscript
