The experience garnered in Spain was very important to the development of the Luftwaffe. The war allowed them to hone and develop their tactics, train their officers, and to become the most practised air force in the world at conducting close support of ground troops. In effect, the Spanish Civil War proved to be the training ground for the Blitzkrieg which would be unleashed across Europe in the years that followed. In this rigorous new analysis, Legion Condor expert James Corum explores both the history and impact of the Luftwaffe’s engagement during the Spanish Civil War and the role that engagement played in the development of the Luftwaffe strategy which would be used to such devastating effect in the years that followed. Illustrated throughout.
