Just completed this book and thought I would let members know this is definitely worth while reading. Author makes it clear it was certainly no easy walk-over for the German forces in the east from June 22 to mid September. Granted a victory which bagged hundreds of thousands Soviet prisoners as well as destroying or capturing vast amounts of materiel but was also costly to the germans in terms of men and equipment. Also dicusses the arguing and differences of opinion between Guderian and Bock concerning displacement of troops to Guderian's sector of the front. Very well written and informative. This is one book I have found to be exceptional. Hope others will enjoy also.
