After long years of studying sources and literature, Werner Haupt presents the military history of one of the larger theaters of World War II. The completion of the history of ""Army Group North"" is the result of the author's utilization of all German and Russian literature, as well as those combat diaries and documents of the committed troop units that are available in German archives. In addition, the author was assisted in clearing up several questions by the advice of former members of the army group - from commanders to drivers. This series by Werner Haupt will continue with a volume each on Army Group Center and Army Group South. The author served in the German Army as a soldier and officer in the northern sector of the Eastern Front during the Second World War. He is also the author of Assault on Moscow - 1941 (available from Schiffer Publishing Ltd.).
