Blitzkrieg 2020 History This illuminating ten-part series tells the story of World War ll through the ten most pivotal turning points in the conflict. Gripping story-telling illustrated with exquisitely restored and colourised archived films and supported by a global cast of stellar historians bring this crucially important era in history to life. In the first chapter, Britain and France declare war when Hitler invades Poland. In May 1940 the Germans attack Holland and Belgium as a decoy. As the Wehrmacht comes through the Ardennes and the Luftwaffe strikes in force, French leaders are caught like rabbits in headlights. The Germans are on a drug called Pervitin, which beats off fatigue, and reach the Atlantic coast. There is a danger that the Germans will encircle the Allies and cut them off from the sea. But Hitler issues his Halt Order and some 340,000 Allies are evacuated.
