The Dunkirk story took place during World War II.

World War II was a huge war between 1939 and 1945 involving many countries around the world, who were fighting each other for power.

There were many important battles and military missions during the war.

Dunkirk was one of these important military missions, which happened in May 1940.


During the war, some countries joined together to fight with each other.

British, French and Belgian soldiers were on the same side. They were known as the Allied troops.

In 1940, the Germans invaded France. They also invaded Belgium and Holland.

They beat the British, French and Belgian soldiers back to the port of Dunkirk, which is on the north coast of France.

The Allied troops found themselves trapped at the beaches there, surrounded by the Germans.

So the British prime minister at the time, Winston Churchill, ordered a fleet of 900 boats to travel from Britain to Dunkirk to rescue the soldiers and bring them back to England to safety.

More than a quarter of a million people were rescued from the beaches of Dunkirk during the mission.

Why is it important?

World War II carried on for another five years after the mission on the Dunkirk beaches took place.

The story of the Dunkirk rescue is still told today as many people risked their lives to save so many others.

Mark Rylance, who is an actor in the film, says: "It was a miraculous retreat."

It was important because even though the British Army and Allies had to flee France, it meant that they lived to fight another day and they eventually went on to win the war.

Dunkirk is a 12A film released on Friday 21 July in the UK
