フランツ・ハルダー
Less well known, but perhaps more significant, was Marshall's effort to assemble German officers after the war to write histories and analyses of battles in all theatres of the European war. At the height of the project, over 200 German officers participated, including Heinz Guderian and Franz Halder. Hundreds of monographs were written based on this data project, of which three are available in commercial print.
