The armour clashes in May 1940 were the biggest the world had yet seen, as the sweeping German advances of that period came to epitomize Blitzkrieg. The Wehrmacht's Panzer III was well matched by the French Somua S35 tanks, the two representing very different design philosophies and yet both ranking among the best in the world at the time. Fully illustrated with specially commissioned colour artwork, this work draws upon the latest research to provide a definitive analysis of the clash between these two high-quality, cutting-edge tank designs. It describes one of the key duels at the heart of a new type of warfare, in the epic battles at the outset of Hitler's conquest of France and the Low Countries.
