France 1940 was arguably the Wehrmacht's greatest military achievement - conquering the country in just a few weeks, after having failed to do so in all of World War I. New Panzer tactics, dubbed 'Blitzkrieg', were at the heart of the German victory. In this book, renowned armor expert Steven J. Zaloga reassesses the armored force that made this triumph possible, and explains that although the Panzers won their reputation in France, they were far from being a technological juggernaut. The vast majority were the small Panzer I and Panzer II light tanks, while the more effective medium tanks such as the Panzer III and Panzer IV were relatively few in numbers. Outlining the full range of tanks deployed, their technical qualities, organization, and tactics, this book pinpoints how training and doctrine rather than technology was the root of the Germans' effectiveness. Including unpublished photos and superb new artwork, this volume offers new insights into the reality of Germany's Panzer force in its most famous conquest.
