This book is a stimulating and entirely plausible insight into how Hitler and his generals might have defeated the Allies, and a convincing sideways look at the Third Reich's bid at world domination in World War II. What would have happened if, for example, the Germans captured the whole of the BEF at Dunkirk? Or if the RAF had been defeated in the Battle of Britain? What if the U-Boats had strangled Britain with an impregnable blockade, if Rommel had been triumphant in North Africa or the Germans had beaten the Red Army at Kursk?
