Ivor Jones new book vividly describes the cunning night-time decoys which saved Cardiff, indeed Wales itself from German bombings during the Second World War. By distorting what the German bombers could see from the air, the Ministry of Home Security was successful in averting hundreds and thousands of bombs from residential areas of the country. False lights were created, to mislead the German bombers when flying over the area looking for targets. During the blackout, it was their plan to place these lights in open countryside, or around the coast. Fully illustrated with photographs and maps, this is a fascinating insight into a previously overlooked aspect of the Second World War.
