Much like Christopher Nolan’s Dunkirk, Sam Mendes’s 1917 thrusts viewers in the heart of war using innovative filming techniques.

While Nolan’s World War II flick depicts Operation Dynamo and the events that took place in the French town, Mendes’s takes us back to the Great War and focuses on two young British soldiers who must deliver warning of an impending German ambush that could save thousands of lives.

Dean-Charles Chapman and George MacKay play Blake and Schofield, the messengers tasked with traversing the active front. Filmed to look like one take, the movie went on to win Best Cinematography, Best Sound Mixing and Best Visual Effects at the 92nd Academy Awards.

But did this extraordinary mission this really take place? Here’s everything you need to know about the accuracy of 1917.

Is 1917 a true story?

In short: sort of. In a bit longer: 1917 is loosely based on a story Mendes was told by his grandfather – Alfred H Mendes, who served in the war – as a child.

During the conflict, Alfred was awarded a Military Medal for volunteering as a runner during 1917’s Battle of Poelcappelle, weaving through machine gun fire to deliver messages.

Writing in his memoirs, Autobiography of Alfred H Mendes 1897-1991, Alfred recalls: “In spite of the snipers, the machine-gunners and the shells, I arrived back at C Company’s shell hole without a scratch but with a series of hair-raising experiences that would keep my grand and great-grandchildren enthralled for nights on end.”
