“The situation was incomparably worse than we had imagined” (Winston Churchill). In May 1940, Britain faced a military disaster. Outgunned and out manoeuvred, young soldiers fought a desperate retreat as the Nazi war machine closed in. Trapped around the port of Dunkirk, the Army waited for rescue without food, supplies or hope. What happened next is the stuff of legend a bold seafaring operation which turned defeat into triumph. Using rare archive film, this is the story of the rescued and rescuers in their own words. Composed entirely from previously unseen colour film, witness this historic mission.
