In the Dunkirk evacuation, codenamed Operation Dynamo and also known as the Miracle of Dunkirk, or just Dunkirk, more than 338,000 Allied soldiers were evacuated during the Second World War from the beaches and harbour of Dunkirk, in the north of France, between 26 May and 4 June 1940. The operation began after large numbers of Belgian, British, and French troops were cut off and surrounded by German troops during the six-week Battle of France.
