In chapter 10, Lieutenant William Carsell-Brown and his squad have been ordered to head for the channel port of Dunkirk. An evacuation of allied troops will begin immediately in a bid to save them from being taken prisoner by the German army. All type of boats are sailing from Britain to Dunkirk on a vital rescue mission. Allied troops have been instructed to form an orderly queue on the beach at Dunkirk. This queue stretches out into the sea where troops stand up to their waist in water.
