Despite the draconian provisions of the Versailles treaty, the German armed forces operating under the new Nazi regime were able to secretly assemble a modern mechanised strike force incorporating tanks, artillery and aircraft. Determined to avoid a repeat of the static warfare of the trenches the Wehrmacht honed its new tactics and the result has become known to posterity as 'Blitzkrieg' or Lightning War.

This new form of warfare was unleashed on Poland in September 1939 and quickly proved its worth. In May 1940 the Blitzkrieg reached its zenith with the fall of France. This powerful film incorporates rare footage from German and Allied sources to present a stunning portrait of the Blitzkrieg in action from the thirties to the fall of France.
