The world has lacked an authoritative history about the role of Franklin Delano Roosevelt the war leader in World War II. He died before beginning an autobiography, although he had accumulated many notes and files. Winston Churchill of course wrote the supposed definitive work on the subject, but, as it develops, did some serious violence to veracity, particularly as to the many areas where he unsuccessfully disagreed with FDR. The British military historian Nigel Hamilton has accessed these and other materials and published a trilogy constituting the definitive history that FDR did not live to write: the story of World War II from FDR’s perspective.
