During World War II, a secret department was formed within Britain's Air Ministry. It co-ordinated a strategy to defeat German bombing using deception. With the help of leading technicians from the film industry, ingeniously designed decoy towns, airfields and military bases were built throughout the UK. This work presents a detailed study of these bombing decoys, both at war - through their design, patterning and operations - and at peace - through their fragmentory survival as enigmatic features of the modern landscape. The book has been compiled in support of English Heritage's initiatives to study and preserve Britain's wartime remains.
