You’ve probably seen the movie posters or caught a snippet of the film on a streaming service and thought it was just another "inspired by a true story" Hollywood exaggeration. It sounds like a punchline. Two dentists walk into a war. But the real history behind Two Men Went to War is actually weirder, riskier, and way more bureaucratic than the 2002 movie even lets on.
History is full of generals and snipers. We don’t usually talk about the guys whose primary job was filling cavities in the Army Dental Corps.
In 1942, the British Army was bracing for the long haul. Sergeant Peter King and Private Leslie Cuthbertson weren't satisfied with staying in a clinic in Aldershot while the world burned. They wanted in. They didn't have orders, they didn't have permission, and they certainly didn't have a boat. What they did have was a stack of dental tools, some stolen grenades, and a very specific kind of British madness.
What Really Happened with Two Men Went to War
The core of the story revolves around Peter King. He wasn't some wide-eyed kid; he was a veteran of the Spanish Civil War. He had seen real combat. When he found himself relegated to the Dental Corps during World War II, he felt like he was rotting. Cuthbertson was his assistant, a younger man who basically got swept up in King’s intense charisma and frustration.
They didn't just "go to war" in a general sense. They deserted.
That’s a heavy word. In 1942, deserting your post during wartime could get you executed or at least thrown into a very dark hole for a very long time. They left a note for King’s wife and essentially went AWOL. Their "invasion" plan involved taking a train to Cornwall, stealing a civilian boat, and rowing/sailing across the English Channel to occupy France.
Honestly, the logistics were a nightmare. They had no radio. They had very little food. They had a handful of grenades and two pistols. Most people think the movie Two Men Went to War plays this for laughs, but if you look at the actual military records from the era, the British High Command was genuinely confused. They didn't know if these guys were spies, lunatics, or heroes.
The Journey Across the Channel
The crossing wasn't a smooth sailing adventure. It was miserable.

They spent days at sea in a small, open motorboat. They got sick. They got lost. When they finally hit the coast of France near Cherbourg, they didn't find a massive Nazi battalion to dismantle. Instead, they found a quiet stretch of coastline.
King and Cuthbertson actually managed to throw their grenades at a German train and a signal box. It wasn't the "turning point of the war," but it was a legitimate act of sabotage carried out by two guys who technically weren't supposed to be there.
Why the British Military Was Embarrassed
The real tension in the Two Men Went to War narrative isn't just the fight against the Germans. It's the fallout with the British Army. When they returned—and they did return, which is a miracle in itself—they weren't greeted with medals and a parade.
They were arrested.
The Army had a massive problem on its hands. If they treated King and Cuthbertson as heroes, they’d be encouraging every frustrated cook and clerk to desert their posts and start their own private wars. If they treated them as traitors, they’d look like heartless bureaucrats punishing "brave boys" who just wanted to fight.
Major General Robert Laycock eventually got involved. The story goes that Winston Churchill himself heard about the "Dental Commandos" and found the whole thing hilarious, which likely saved them from a much harsher sentence.
The Movie vs. The Reality
Released in 2002 and directed by John Glen—the guy who directed five James Bond movies—the film takes some liberties. Derek Jacobi and Kenneth Cranham do a great job, but the movie leans heavily into the "Ealing Comedy" vibe.

In the film, there’s a lot of focus on the bumbling nature of their departure. In reality, Peter King was a deeply serious, perhaps even slightly unstable, individual who was haunted by his experiences in Spain. He wasn't a "bumbler." He was a man who felt the moral weight of the Nazi occupation so heavily that he couldn't sit in a dental office anymore.
- The Gear: In the movie, it looks like a camping trip gone wrong. In real life, they carried official Army-issue gear they had pilfered, making them look like a two-man recon team.
- The Combat: The film dramatizes the skirmishes. The real-life "battle" was short, chaotic, and mostly involved hit-and-run tactics against infrastructure.
- The Resolution: The film ends on a somewhat triumphant note. The reality was a messy court-martial that left a permanent mark on their military records, even if they were eventually allowed to serve in more active roles.
Why We Still Care About This Story
We live in an era of "big history." We talk about the 101st Airborne or the desert rats of the SAS. But Two Men Went to War hits a different nerve. It’s about the individual vs. the machine.
It’s about that feeling of being stuck in a job that feels meaningless while the "real world" is happening somewhere else. Most of us aren't dentists in 1942, but we’ve all felt that itch to do something that matters, even if the rules say we can't.
There’s also the sheer absurdity. The idea of "Dental Corps" stationery being used to plan a cross-channel invasion is objectively funny. It reminds us that history isn't just made by stone-faced statues; it's made by weirdos, rebels, and people who are just tired of waiting for permission.
Expert Insight: The Psychology of the Dental Commandos
Military historians often point to King and Cuthbertson as a classic case of "war fever." By 1942, the UK had been under threat for years. The Blitz had happened. The tension was suffocating. For a man like King, who had already seen the face of fascism in Spain, the "waiting" was a form of torture.
The British Army at the time was notoriously class-conscious and rigid. If you were a dentist, you were a dentist. The idea of "lateral movement" into a commando unit was almost unheard of without high-level connections. Their act wasn't just a strike against Germany; it was a strike against the British class system that told them where they belonged.
Misconceptions to Clear Up
- They weren't "incompetent": They actually navigated the Channel successfully. Most amateur sailors would have died in those waters.
- They weren't "pardoned" immediately: They spent time in a military prison. The "Churchill saved them" bit is likely true in spirit, but the paperwork shows they still faced significant disciplinary action.
- It wasn't a "suicide mission": They fully intended to come back. They weren't looking for glory in death; they were looking for action in life.
Actionable Steps for History Buffs and Film Fans
If this story fascinates you, don't just stop at the 2002 movie. There are ways to dig deeper into this specific niche of "unauthorized" military history.

Check the National Archives.
You can actually look up the service records and the court-martial summaries of the Royal Army Dental Corps from this period. Seeing the dry, bureaucratic language used to describe their "unauthorized absence" adds a layer of reality that no movie can capture.
Watch the Film with Context.
Now that you know Peter King was a Spanish Civil War vet, watch Kenneth Cranham’s performance again. You’ll see the "edge" in the character that the script sometimes tries to hide behind jokes. It changes the movie from a comedy to a character study of a man on the brink.
Explore the "Little Ships" History.
The boat they stole was part of a larger tradition of civilian vessels used in the war effort (most famously at Dunkirk). Researching the "Little Ships of Dunkirk" will give you a better understanding of the types of craft King and Cuthbertson were dealing with in the choppy Channel waters.
Visit the Museum of Military Dental Health.
Yes, it exists. It’s located at the Defence Medical Academy in the UK. It offers a bizarrely fascinating look at the role dentists played in the world wars, which—believe it or not—went way beyond just pulling teeth. They were often on the front lines dealing with horrific facial injuries.
The story of the Two Men Went to War serves as a reminder that the line between a hero and a headache for the chain of command is often just a matter of who wins the fight. If they had died at sea, they would have been forgotten deserters. Because they landed, fought, and came back, they became a footnote that eventually turned into a feature film.
History is written by the winners, but it’s often started by the people who were too impatient to wait for the starting gun.
