The Historical Reality Behind the Film ‘1917’
The 2019 war film 1917, directed by Sam Mendes, draws its central narrative from the real-life experiences of Alfred H. Mendes, the director’s grandfather. While the film follows two fictional British soldiers, Schofield and Blake, on a perilous mission to deliver an urgent message across enemy lines, the core premise reflects the genuine dangers faced by messengers during the First World War. According to the Imperial War Museums, the film captures the isolation and tactical uncertainty that defined the conflict on the Western Front.
Who was Alfred H. Mendes?
Alfred H. Mendes served as a lance corporal in the 1st Battalion, Rifle Brigade, during the First World War. Born in Trinidad, he moved to England to enlist in the British Army in 1915. He was deployed to France, where he often operated as a runner. These soldiers were tasked with carrying vital communications between trenches and command posts when telephone lines were severed by artillery fire. The Imperial War Museums note that Mendes’s firsthand accounts of the “no man’s land” terrain and the constant threat of German ambushes provided the atmospheric blueprint for the film’s tense, immersive journey.

How did the film ‘1917’ use real-world tactics?
The film is widely recognized for its “one-shot” cinematography, a technique designed to keep the audience in constant motion alongside the protagonists. Sam Mendes utilized this approach to mimic the relentless pace of a soldier’s mission. Historically, the British Army relied heavily on runners because communication technology was frequently unreliable. Historians at the National Archives confirm that the “messenger” role was one of the most hazardous positions in the infantry, as runners were exposed to sniper fire, gas attacks, and artillery barrages while moving through open ground.
Fact vs. Fiction: Comparing the Film to History
While the film is grounded in the experiences of Alfred H. Mendes, it remains a dramatized work of historical fiction. The following table contrasts elements of the film with historical realities of the 1914–1918 conflict:

| Element | 1917 (Film) | Historical Reality |
|---|---|---|
| Primary Mission | Delivering a warning to stop an attack. | Runners often carried orders, reports, or tactical updates. |
| The “One-Shot” | A continuous, unbroken perspective. | A stylistic choice to heighten tension and immersion. |
| The Source Material | Inspired by family stories. | Based on the memoirs and experiences of Alfred H. Mendes. |
Why the ‘Runner’ role was critical
The role of a runner was essential because the technology of the era could not keep pace with the fluid nature of trench warfare. According to the BBC History archives, radio technology was in its infancy and heavy, while field telephones were easily destroyed by shellfire. This forced commanders to rely on human messengers to coordinate movements. For a soldier like Alfred H. Mendes, the mission was not just a tactical necessity—it was an act of survival in an environment where orders were the only link between a unit and total destruction.
The film concludes by highlighting the immense human cost of the conflict. By focusing on the singular, intimate struggle of two men, 1917 serves as a tribute to the millions of soldiers whose stories were often lost in the broader history of the Great War.
