One of the biggest films of the winter is out today – Dunkirk.
Harry Styles will be making his acting debut in the movie.
Dunkirk tells the story of a very important event which took place in World War II.
Harry has said: “It’s a very emotional story.”
What is Dunkirk?
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.
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 250,000 people were rescued from the beaches of Dunkirk during the mission.
Many people risked their lives to save the soldiers stranded at Dunkirk
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.
