This book tells the story of the aerial campaign undertaken by the Zeppelins of the German Naval Airship Division over Britain's industrial heartland. Cross explains how, under Peter Strasse, the original Zeppelin airships were developed to fly above the range of fighter planes and artillery. He tells how the British then developed higher-flying planes which nullified the threat of the Zeppelins. Using first-hand accounts and archival photographs, the author describes the battles fought over Britain's major cities, and explains the Zeppelin's shortcomings as an instrument of war and as a peace-time conveyance.
