It's been a State secret for more than 70 years: The official line in the UK has always been that it never happened - but this new work challenges the assertion that no German force set foot on British soil during World War Two (the Channel Islands excepted), on active military service.
Although interesting in part, all the evidence points to the whole purpose of the book not actually having happened. Well researched but, I feel the author, rather than trying to prove or disprove that a raid took place was almost willing it to be true. At that particular time in the war, any German incursion onto the British mainland or even the Isle of Wight, would have been exploited massively by the German High command, and seen as a huge success. All in all, an interesting story and worth a read, but that is what it is. A story.
