An account of some of Britain's subterranean defence, factory and storage sites in the Second World War. When war seemed inevitable in the late thirties a number of huge, sophisticated, and technically complex ammunition depots, buried deep underground, were built to house the million of tons of explosives. The author describes the many problems that had to be overcome in converting the stone mines with their 100% humidity and shaky ceilings. Concentrates on Corsham Stone Mines with chapters on Drakelow, the Manod Slate Mine in North Wales where art treasures of the National Gallery were stored and many others. 45 photos, 8 maps.
