The true story of the 'Miracle of Dunkirk'- the most daring and ambitious rescue mission of all time. In May 1940, nearly 400,000 British and French soldiers were cornered by the might of the German army on the beaches of a northern French port: Dunkirk. They faced annihilation or capture and with their loss, the German invasion of Britain would surely follow. The truth of how the allied forces were driven to this dire position and the extraordinary tale of their successful rescue while under daily withering fire from the Luftwaffe is told in this gripping BBC documentary. Here is the moving testimony of British Expeditionary Force and Royal Navy veterans and the astonishing accounts of men who manned the 'Little Ships'- the armada of 600 defenseless craft that were pressed into service-and on whose skill and courage the outcome of the mission depended. Watch gripping archive footage of the armoured Blitzkreig across northern Europe, terrifying gun camera film from screaming Stukas dive-bombing the makeshift quay at Dunkirk and finally, unforgettable images of an army who never gave up hope being delivered from the sea by the most unlikely vessels imaginable. Join Dan Snow on an unforgettable journey on the road to Dunkirk, in the steps of a vanquished army that survived and escaped against all odds.... to return and to prevail.
