The evacuation from Dunkirk was one of the biggest operations of the Second World War and was one of the major factors in enabling the Allies to continue fighting.
It was the largest military evacuation in history, taking place between May 27 and June 4, 1940. The evacuation, known as Operation Dynamo, saw an estimated 338,000 Allied troops rescued from northern France. But 11,000 Britons were killed during Operation Dynamo, and another 40,000 were captured and imprisoned.
Described as a 'miracle of deliverance' by wartime prime minister Winston Churchill, it is seen as one of several events in 1940 that determined the eventual outcome of the war.
The Second World War began after Germany invaded Poland in 1939, but for a number of months there was little further action on land. But in early 1940, Germany invaded Denmark and Norway and then launched an offensive against Belgium and France in western Europe.
