Based on years of archival research and interviews with the last surviving aides and Roosevelt family members, Nigel Hamilton offers a definitive account of FDR’s masterful — and underappreciated — command of the Allied war effort. Hamilton takes readers inside FDR’s White House Oval Office — his personal command centre — and into the meetings where he battled with Churchill about strategy and tactics and overrode the near mutinies of his own generals and secretary of war.
