Robinson's thesis is that the RAF didn't save Britain from invasion by defeating the Luftwaffe. The battle was at best a draw, and it was the advancing season and Hitler's eyes turning toward Russia that did the job. Robinson also seriously questions whether the Luftwaffe could ever have suppressed the Royal Navy sufficiently to prevent it from making effective night attacks on any invasion fleet and leaving the Germans to totter ashore in no fit state to deal with even a battered British army. Some may object that he overlooks the effect of German air superiority on the Battle of the Atlantic in British waters, yet he points out that Hitler and Goring were totally blind in the area of naval strategy and might not have been able to do anything with such superiority even had they gained it. A solid, well-informed, gentlemanly piece of myth busting and a useful, provocative addition to Battle of Britain literature by the author of one of the outstanding novels on the subject, Piece of Cake (1984).
