Input: The first edition came out in 1998 and, six years on, this work has not been surpassed for its importance as an analysis of WWII joint warfighting, the Luftwaffe's way of war, airpower in the Crimea, airpower in the Caucasus, airpower at Stalingrad, and naturally the Stalingrad airlift itself.The reasons for this book's immediate "classic" status are easy to pick: totally accurate citing of hundreds of never-before-used sources in several languages drawn from major archives; a highly original approach to the writing of campaign histories; a clear argument; a fair and balanced approach; no Wehrmacht-devotee comments or tone (all too common I'm afraid); a wonderfully readable writing style; and precise footnotes that help the reader to determine the reliability of all claims or statements.A true model of a WWII campaign analysis. VERY highly recommended!
Output:
Positive
