Hitler envisaged a very quick war. The type of drawn-out stalemate struggles in which he himself fought during the First World War were to be replaced with a new, far more devastating tactic. 'Blitzkrieg' (meaning 'Lightning War') was his operation to force a British surrender by the carpet bombing of London and Birmingham by bomber and, later, with the V2. Using Pathe Newsreel and memories of the British that survived the carnage, this documentary examines Britain through the 'Blitz' years, 1939-1941.
