On 28 September 1918, in an incident that would go down in the lore of World War I history—although the details of the event are still unclear—Private Henry Tandey, a British soldier serving near the French village of Marcoing, reportedly encounters a wounded German soldier and declines to shoot him, sparing the life of 29-year-old Lance Corporal Adolf Hitler.

Tandey, a native of Warwickshire, took part in the First Battle of Ypres in October 1914 and the Battle of the Somme in 1916, where he was wounded in the leg. After being discharged from the hospital, he was transferred to the 9th Battalion in France and was wounded again during the Third Battle of Ypres at Passchendaele in the summer of 1917. From July to October 1918, Tandey served with the 5th Duke of Wellington Regiment; it was during this time that he took part in the successful British capture of Marcoing, for which he earned a Victoria Cross for "conspicuous bravery."

As Tandey later told sources, during the final moments of that battle, as the German troops were in retreat, a wounded German soldier entered Tandey’s line of fire. "I took aim but couldn’t shoot a wounded man," Tandey remembered, "so I let him go." The German soldier nodded in thanks, and disappeared.

Though sources do not exist to prove the exact whereabouts of Adolf Hitler on that day in 1918, an intriguing link emerged to suggest that he was in fact the soldier Tandey spared. A photograph that appeared in London newspapers of Tandey carrying a wounded soldier at Ypres in 1914 was later portrayed on canvas in a painting by the Italian artist Fortunino Matania glorifying the Allied war effort. As the story goes, when British Prime Minister Neville Chamberlain traveled to Germany in 1938 to engage Hitler in a last-ditch effort to avoid another war in Europe, he was taken by the Führer to his new country retreat in Bavaria. There, Hitler showed Chamberlain his copy of the Matania painting, commenting, "That’s the man who nearly shot me."

A WW1 legend that Adolf Hitler's life was spared by a soldier who had him in his sights has been questioned by new research. Pte Henry Tandey, who was serving with the Duke of Wellington's Regiment, reputedly had a chance to kill the future Führer during fighting at Marcoing, near Cambrai, France, on the day he won a Victoria Cross, 28 September 1918. But he could not bring himself to kill a wounded man and instead let Hitler go. Hitler was indeed wounded in northern France, but work by historians has cast new doubt on the story. Documents in the Bavarian State Archive show that Corporal Hitler was on leave on the day in question and nowhere near the battle.  The authenticity of the Tandey-Hitler encounter remains in dispute, though evidence does suggest that Hitler had a reproduction of the Matania painting as early as 1937—a strange acquisition for a man who had been furious and devastated by the German defeat at Allied hands in the Great War. Twice decorated as a soldier, Hitler was temporarily blinded by a mustard gas attack in Belgium in October 1918 and was in a military hospital in Pacewalk, Germany, when he received news of the German surrender. The experiences of battle—first glory and ultimately disillusion and despondence—would color the rest of Hitler’s life and career, as he admitted in 1941, after leading his country into another devastating conflict: "When I returned from the War, I brought back home with me my experiences at the front; out of them I built my National Socialist community."
