Preface Zitat: Two preliminary drafts of the study and a series of questionnaires were distributed to a committee of former German general officers for reply and comment on their part in planning and operations, and to fill gaps in the official records. These former German officers included Generaloberst Franz Haider, Chief of the Army General Staff through the period of the Polish Campaign, Generaloberst Hans von Salmuth, General der Artillerie Walter Warlimont, General der Infanterie Guenther Blumentritt, and General der Infanterie Kurt von Tippelskirch. The replies and comments of these surviving key participants are referred to in the footnotes and are available in the author's file in the Office of the Chief of Military History for study by interested researchers.
