The Hitler-backed German special forces who landed on the Isle of Wight expected to meet lightly armed members of the Home Guard – Britain’s so-called “Dads’ Army”.

But they in fact faced crack British commandos who all bit wiped them out.

And, for morale and propaganda reasons, the entire event was erased from, history.

But now Dr Dietrich Andernacht has claimed he was part of a top secret operation to steal equipment from RAF St Lawrence radar station on August 15 1943, in a book by historian Adrian Searle.

The official line has always maintained that no Germans forces made it onto British soil during the war, aside from the Channel Islands.

Churchill’s Last Wartime Secret: The 1943 German Raid Airbrushed from History describes that in the raid 12 German soldiers were transported via U-boat from the Channel Islands that were under Nazi occupation.
