The history of these defences (as well as one of my photos), along with other initiatives deployed during the Second World War, are featured in a book by Gwilym Roberts called Engineering Hitler’s Downfall. It was published late last year and includes a Forward by Admiral Lord West.
You can purchase the book online (for £18.99) by clicking here.
