The latest summer blockbuster to hit the big screen, Dunkirk, which was released on July 21, tells the story of the very real-life battle that took place at the start of World War II. After Nazi German forces pushed the Allies back, they became stranded on the beaches of Dunkirk, France—with limited ships to transport them across the channel back to England and no way to get to them with cover (the harbor was incredibly shallow, making it nearly impossible for large destroyers to come anywhere near shore).
But on May 26, Operation Dynamo began, with newly elected Prime Minister Winston Churchill calling for help from civilians with their own vessels. Aided by nearly 400 smaller ships, 338,226 soldiers had been rescued by the end of the evacuation on June 4. But what happened after that—and to the men who were not evacuated? Here are eight things the Dunkirk movie didn’t tell you.
1. The Battle of Dunkirk is considered to be a major defeat for the British, and a victory for the Germans. Winston Churchill described it as a “colossal military disaster.”
As Walter Lord recounts in his book, The Miracle of Dunkirk, “It’s hard to say exactly when Dunkirk officially fell. The Army Group B war diary put the time at 9:00 a.m. … X Corps said 9:40 … the 18th Army, 10:15. Perhaps the most appropriate time, symbolically anyhow, was the moment the swastika was hoisted on the eastern mole—10:20 a.m.” So even though the evacuation effort, termed Operation Dynamo, was a success, it did not mean victory for the Allies.
2. After the last rescue boat left Dunkirk harbor, Germans captured at least 80,000 British and French troops.
Some of these men were forced to march back to Germany—where they served as POWs until the end of the war in 1945.
3. There were more than just European soldiers present at Dunkirk. Soldiers from Morocco, Algeria, Tunisia, and other African colonies, as well as the Royal Indian Army Services Corps, were key in delaying the German attack.
Though some non-white actors can be seen in the crowd scenes, British and French actors fill all of the film’s speaking roles. The Royal Indian Army Services Corp companies were not only on the beach, but also helped transport supplies over areas that could not be accessed by the BEF’s (British Expeditionary Force’s) motorized companies. The French army at Dunkirk included soldiers from African colonies, who were crucial in the fight as well.
4. Soldiers at Dunkirk were able to evacuate because Hitler mysteriously ordered his troops to halt—even though it could have been a major turning point in the war.
Nolan’s story is about the Allies’ survival, so we don’t see much of the Nazis in the film—apart from planes with faceless pilots and the few men who [SPOILER] capture a British pilot at the film’s end. Historically, after the Nazis surrounded the Allies at Dunkirk, Hitler commanded his forces to halt—and the reason behind that decision is still debated to this day.
5. The Battle of Dunkirk marked the end to the “Phoney War”—a period during which no fighting was done for eight months after a declaration of war.
The Phoney War began when Nazi Germany invaded Poland on September 1, 1939, and the United Kingdom and France declared war on Nazi Germany two days later. Though war had been declared, none of the Western Allies did anything for eight months—until Germany attacked France on May 10, 1940, just 10 days before the Battle of Dunkirk.
6. How did the Allies get backed into Dunkirk in the first place?
After the “Phoney War” came to an end, the Germans invaded the Netherlands and advanced westward. In response, the French army entered Belgium—hoping to engage with the Germans in the Netherlands—but by the time the French got there, the Germans had already crossed through most of the country—coming out of the Ardennes forest and then turning north towards the English Channel. Though the Allies tried a series of counter-attacks, they failed to stop the Germans and were backed into the coast on May 20, 1940.
7. British troops left behind ammunition and guns on the beach—amounting to a serious loss of material.
This included 2,400 artillery guns, 65,000 vehicles, and 68,000 tons of ammunition.
8. Directly after Operation Dynamo, the official name of the Dunkirk evacuation, German forces caused yet another British evacuation, Operation Ariel—just nine days later.
Following the military collapse in the Battle of France (which started before the Battle of Dunkirk), more Allied forces and civilians were evacuated from ports in western France from June 15-25, 1940. In total, 191,870 troops and civilians of many nationalities were evacuated.
