After almost five years of hard fighting, the time came at last to invade ‘Fortress Europe’. Featuring some rare footage from a German archive, Britain at War shows the drama of the D-Day landings, through the tank battles that took place in the Villers-Bocage, on to the prolonged battle for Caen (a third day target that took three months to achieve) and finally to the amazing ‘missed opportunity’ at the Falaise pocket.
