Dunkirk — France
The entire film — Operation Dynamo, the evacuation of 338,000 Allied troops from Dunkirk's beaches and harbour. May–June 1940.
Operation Dynamo ran from May 26 to June 4, 1940. Using 861 vessels — including hundreds of civilian 'little ships' — 338,226 men were evacuated. Churchill called it a 'miracle of deliverance' while warning that wars are not won by evacuations.
