The Day Enemies Became Brothers: The Incredible True Story of the Battle for Castle Itter

 The war was supposed to be over, but for a small group of Americans and Germans at Castle Itter, the real nightmare was just beginning. In a medieval fortress turned luxury prison, the strangest alliance in military history was born.

A cigar-chomping American tank captain named Jack Lee and a disillusioned German major named Josef Gangl did the impossible: they joined forces.

As the fanatical SS surged up the hill with 88mm guns and mortars, intent on slaughtering the high-profile French prisoners inside, Lee and Gangl ignored their uniforms and focused on survival.

It was a brutal, desperate shootout where German soldiers died defending French politicians against their own countrymen. When their only tank exploded and ammunition ran dry, they prepared for a suicidal hand-to-hand last stand in the castle courtyard.

This is a story of courage that transcends borders and a reminder that even in the darkest hours of human history, the right choice can still be made. Read the full account of the Battle for Castle Itter and the hero who died fighting for his enemy in the comments section.

On May 5, 1945, the world was on the precipice of a new era. Adolf Hitler was dead in his bunker, Berlin had fallen, and the Nazi war machine was collapsing in a state of total surrender.

To most of the world, the guns had already fallen silent. But high in the North Tyrolean Alps of Austria, atop a hill occupied by the medieval fortress known as Castle Itter, the strangest and most symbolic battle of the Second World War was about to reach its bloody climax.

If you had been standing on those castle walls with a pair of binoculars, you would have witnessed a sight that defied every rule of conventional warfare. You would have seen Captain John “Jack” Lee, a quintessential American tank commander who looked like he had been cast for a Hollywood war epic, barking orders. Beside him stood Major Josef Gangl, a decorated officer of the German Wehrmacht.Two Invasions of Belgium By Germany in Two World Wars: 1914 and 1940 | War  History Online

Most shockingly, you would have seen American GIs in olive drab and German soldiers in field-gray uniforms standing shoulder-to-shoulder, sharing ammunition, and firing their machine guns at a common enemy: the fanatical 17th SS Panzergrenadier Division.

This was the Battle for Castle Itter—the only time during the entire conflict that American and German forces fought as allies. It was a day when the labels of “friend” and “foe” were stripped away, replaced by a desperate, shared mission to protect human life against the final, dying gasps of Nazi fanaticism.

The Luxury Cage: Prisoners of the Reich

Castle Itter (Schloss Itter) was no ordinary prisoner-of-war camp. Since 1943, the Nazis had used the 13th-century fortress as a high-security “honor prison” for French VIPs—high-profile individuals who were too valuable to kill but too dangerous to leave free. The guest list was a “who’s who” of pre-war French society: former Prime Ministers Édouard Daladier and Paul Reynaud, General Maxim Weygand, and even the world-renowned tennis champion Jean Borotra.

These were men of immense ego and conflicting political ideologies. Even in captivity, they spent their days arguing about the fall of France and the future of their nation. They shared a mutual hatred for their captors, but they also frequently despised one another. However, as the Allied lines closed in during the spring of 1945, their petty bickering was silenced by a much more immediate threat.

The SS commander of the castle, Sebastian Wimmer, knew the end was near. He also knew the standing orders from Heinrich Himmler: no prisoner was to fall into Allied hands alive. On May 4, as the American 12th Armored Division approached the region, Wimmer and his SS guards took the coward’s way out—they fled into the night.

The French prisoners were suddenly “free,” but they were far from safe. The surrounding woods were crawling with roving bands of fanatical SS troops who were executing anyone—soldier or civilian—who attempted to surrender. The aging French dignitaries were trapped in a fortress with no one to defend them. They managed to arm themselves with abandoned Mauser rifles, but they were politicians and athletes, not a combat unit. They needed a miracle.

The Unlikely Hero: Major Josef Gangl

The miracle arrived in the form of Major Josef Gangl. A veteran of the brutal Eastern Front, Gangl was a career soldier who had grown to loathe the Nazi regime. He had been secretly collaborating with the Austrian resistance to protect local towns from the “scorched earth” policies of the SS. When a Czech cook from the castle managed to reach Gangl’s position on a bicycle, pleading for help, the Major faced a harrowing choice.

Gangl didn’t have enough men to take on the SS division alone. He knew that if he tried to help the French, he would be branded a traitor and executed by his own countrymen. But Gangl was a man of honor. He realized that the only way to save the prisoners was to find the Americans.

In an act of supreme courage, Gangl tied a white flag to his Kubelwagen and drove toward the American lines. He eventually encountered a reconnaissance unit of the 12th Armored Division led by Captain Jack Lee. In a scene that seems pulled from a movie, the German Major saluted the American Captain and explained, in broken English, that he needed help to save the French VIPs from the SS.

Jack Lee was a gambler and a warrior. He looked at the map, chewed on his ever-present cigar, and agreed to the mission. “All right, Fritz,” he reportedly said. “Let’s go get ’em.

The Siege of Castle Itter

Lee’s rescue force was dangerously small: one Sherman tank named the “Besotten Jenny,” seven American infantrymen, and a truckload of Gangl’s Wehrmacht soldiers. As they rolled toward the castle, this bizarre convoy had to fight through SS roadblocks, with the American tank leading and the German infantry providing cover fire.

When they finally breached the castle gates, the French VIPs were underwhelmed. They had expected an entire army; they got one tank and a handful of soldiers, many of whom were the very Germans who had been their enemies 24 hours earlier. Captain Lee, however, wasted no time. He positioned the Besotten Jenny at the main gate, placed German snipers on the walls, and told the French Prime Ministers to stay away from the windows.

On the morning of May 5, the fog lifted to reveal the nightmare: nearly 150 SS troops had surrounded the hill. They were armed with anti-tank guns and a singular, fanatical purpose. To the SS, the German soldiers on the castle walls were the ultimate traitors, and they intended to make them pay.

The battle was fierce and primitive. Ancient stone walls chipped away under heavy machine-gun fire. The French dignitaries, refusing to hide, grabbed rifles and joined the defense. Even the tennis star Jean Borotra proved his mettle, firing from the battlements.

The turning point came when an SS 88mm shell slammed into the Besotten Jenny. The tank burst into flames, destroying the defenders’ only heavy weapon. As the SS began to inch closer to the gates, the situation looked hopeless.

It was during this desperate exchange that Major Gangl saw Prime Minister Paul Reynaud standing in an exposed position. As the Major lunged to push the Frenchman into cover, a sniper’s bullet caught Gangl in the chest. He died instantly—a German officer who gave his life to save a French politician while fighting alongside American soldiers.

The Miracle of the 142nd

By noon, the defenders were down to their last magazines. Captain Lee ordered his men to fix bayonets, preparing for a final, suicidal stand in the courtyard. In a last-ditch effort, Jean Borotra volunteered for a “suicide run.” He vaulted the castle wall and sprinted through a hail of bullets into the forest, hoping to find the main American relief column.

Against all odds, the “Tennis Musketeer” made it. He reached the 142nd Infantry Regiment and guided them back to the castle. Just as the SS were blowing open the main gate, the sound of American relief tanks echoed through the valley. The SS, realizing they were now the ones trapped, broke and fled.

The siege was over. The French VIPs were saved. Captain Lee, soot-stained and exhausted, famously greeted the relief commander by asking, “What took you so long?

A Legacy of Humanity

The Battle for Castle Itter was a minor skirmish in the grand scale of World War II, but it remains one of the most powerful stories of the conflict. It proved that even in the midst of a war that had claimed tens of millions of lives, the human spirit could still choose decency over dogma.

Major Josef Gangl was buried as a hero in the town of Wörgl. Today, a street bears his name, honoring the soldier who chose to die for his “enemies” rather than live for a hateful cause. Captain Jack Lee returned to New York and lived a quiet life, rarely speaking of the day he led a mixed army of GIs and “Krauts.

As we look back on this strange moment in history, we are reminded that heroism doesn’t always wear the uniform we expect. In the high Alps of Austria, on a day when the world was changing forever, enemies became brothers, and for a few hours, the only side that mattered was the side of humanity.
