This is an analysis of the German art of war at the start of World War II. It covers operations by German troops in Spain, Poland, Norway and the Low Countries and demonstrates how the Germans used the combined arms aproach to win the early battles of the Second World War.

It deals in detail with the tactics of Blitzkrieg and the elements of the style - the air arm, armour and artillery. It also looks at what are now called battlegroups as well as offering valuable advice of defence against Blitzkrieg.

This is a very important work which explains how the German method worked and what was needed to make it work.

With a foreword by Tom Wintringham, who fought in Spain.
