Whilst this might seem a little dated, this rather oddly structured book is a fascinating read for anyone interested in the strategy of blitzkrieg. By cutting behind the myth of the German Army's advanced technology it goes a long way to explaining what happened next in the war.
The opening chapters on interwar Germany are fairly standard fare, and to anyone who has studied the period, will not do it justice. The account of Hitler's effective takeover of the German Army is interesting enough, and the account of the campaigns/diplomacy of the late 30s is also interesting.
It is the account of the machinery and tactics of Blitzkrieg that I found most illuminating - the tiny amount of armour available to the German's; the very conventional strategy of the Poland campaign; the German inferiority in every department in the war in France (the opening two weeks of which are, in the authors opinion, one of the few real moments of true blitzkrieg warfare).
I would suggest, it is this lack of strength in depth, and the very specific nature of the terrain blitzkrieg works in, that explain the failure of the Russian campaign, just as much as the weather. It also throws a poor light on the policy of appeasement.
A book for those with an interest in military affairs rather than just politics, but interesting stuff. ( )
