The episode examined in detail the fighting around Mortain where the German counter-attack stalled, and the development of the Falaise pocket, in which the over-extended Germans became trapped in a pincer movement. It then traces the German attempts to escape under bombardment and Hawker Typhoon air attack through the 'Failaise Gap' between Argentan and Falaise into a funnel at Chambois, nicknamed 'the corridor of death' by the Germans, and ending with the battle at Mont Ormel ridge and the final closure of the gap.
