About this book:
In the summer of 1940, the question Britain asked itself was not “will Hitler invade?” but “when?” SEALION, the German invasion plan, provoked the construction of pillboxes, anti-tank stop-lines and islands, coastal defences, heavy-gun emplacements and anti-aircraft batteries, as well as the formation of the Home Guard. New threats replaced SEALION; radar detection systems were expanded during the Blitz years, intelligence-gathering systems and listening posts were established, and covert counter-insurgency groups were formed. In 1944, Britain was once again faced with a new threat; Hitler's “vengeance weapons,” the V rockets. This title provides a concise assessment of the development of Britain's defensive systems, and presents a vivid picture of war on the home front.
