Panzer warfare is synonymous with the Wehrmacht of World War II. This book examines the story of the Panzer's more mysterious ancestors, the little-known panzers of the Great War. Germany was very slow to develop armored vehicles compared to Britain and France. Efforts to catch-up proved difficult, and only a few dozen German A7V tanks were completed in time to take part in the final campaigns of 1918. As a result, the majority of German panzer units actually used captured British tanks, the Beutepanzer. This book traces the development of German panzers of the World War One, including the A7V and its intended but unfinished stablemates.
