This is the first and comprehensive record of all of Hitler's bunkers and command centers, including those built and used, those under construction, and those that never got past planning. Between 1939 and 1945 almost twenty Fuhrerhaupt-Quartier were completed. At the end of the war numerous further projects were being built and countless other suitable sites were being investigated. Franz W. Seidler and Dieter Zeigert have pieced together the history of Hitler's secret headquarters thanks to the diaries of Siegfried Schmelcher, head of the construction project and Leo Muller, site supervisor, both of whom had unparalleled knowledge of the process. Their records include 158 illustrations, documents, and diagrams as well as detailed structural and material references, cutaway plans, safety instructions, and code names. Includes an inside view of Hitler's mountain retreat, the Berghof, and unique photographs of Hitler on campaigns.
