The First Blitzkrieg

In September 1939 a new form of warfare erupted in Europe, one that would forever transform how wars were fought. As German panzers rolled across Poland, a new word was spoken to describe combined armor and air operations: Blitzkrieg. Following the conquest of Poland, Germany would then turn its attention to Scandinavia and then to France and the Low Countries in the first few years of what would become the Second World War. Can you command the German panzers with the same skill as Guderian and Rommel, or as the Allies, can you stop the Wehrmacht where the historical commanders failed?
