The Strangest Alliance: When U.S. and German Soldiers Fought Together at Castle Itter
It was May 5, 1945. Hitler was dead, the Third Reich was collapsing, but in a remote Austrian castle, the war was far from over. A group of France’s most prominent political figures—former prime ministers and generals—were trapped behind stone walls, targeted for liquidation by an elite SS unit. When the prison guards fled, the captives found themselves in a terrifying power vacuum. Their only hope?
A ragtag rescue force consisting of American tankers, anti-Nazi German soldiers, and the prisoners themselves. Together, this unlikely band of brothers faced a sustained, brutal assault by 150 fanatical SS troops determined to destroy them. It is the only time in World War II history that Americans and Germans stood in the same trench, firing at the same enemy. From the desperate defense of the castle courtyard to the tragic death of the German major who gave everything to turn against his own side, this is a story of grit, betrayal, and the ultimate test of loyalty.
Was this a strategic genius move or a desperate act of survival? The events at Castle Itter still leave historians speechless decades later. Prepare to be shocked by the details of this forgotten, cinematic, and absolutely true event that proved, in the darkest moments of history, the enemy of your enemy truly is your friend.

The Second World War was defined by rigid lines of ideology, nationality, and enmity. For six years, the world was split into clear camps: the Allies and the Axis. Yet, in the twilight hours of the conflict—on May 5, 1945, just three days before V-E Day—the chaos of the collapsing Nazi state produced a moment so bizarre, so unprecedented, and so historically unique that it still feels like the product of fiction. Deep in the Austrian Alps, at a 13th-century fortress known as Castle Itter, American soldiers, French political prisoners, and defecting German Wehrmacht troops joined forces to battle a common enemy: the fanatical Waffen-SS.
The Fortress of Ghosts
Castle Itter had become a surreal gilded cage during the war. After the Nazi annexation of Austria, the SS seized the fortress and turned it into a high-security prison for “Very Important Prisoners.” Among those incarcerated were former French Prime Ministers Édouard Daladier and Paul Reynaud, along with legendary military leaders like Generals Maurice Gamelin and Maxime Weygand. By early May 1945, the Third Reich was disintegrating. The commandant of the Dachau concentration camp, to which Itter was a subcamp, committed suicide, and the SS guards at the castle fled, abandoning their posts. The prisoners were suddenly free, yet they remained in extreme danger. They were trapped in a remote location, surrounded by hostile Waffen-SS units still operating under the ideology of total war, who viewed these French leaders as dangerous liabilities to be eliminated.
An Unlikely Call for Help
The prisoners, realizing they were sitting ducks, attempted to find help. A small group, including the former French premier Paul Reynaud, managed to send an urgent plea to the American forces advancing through the region. The request for aid eventually reached Captain John “Jack” Lee Jr. of the U.S. 23rd Tank Battalion. Lee, a man who epitomized the bold, aggressive spirit of the U.S. Army’s armored divisions, didn’t hesitate. He gathered a small force—including a Sherman tank he christened Besotten Jenny—and set off on a dangerous mission into the heart of the Austrian mountains.
But Lee was not alone in his rescue mission. He was joined by Major Josef “Sepp” Gangl, a Wehrmacht officer who had grown disillusioned with the Nazi regime and had been secretly aiding the Austrian Resistance. Gangl, seeking to distance himself from the crumbling Reich, saw an opportunity to perform one final, noble act. He brought a small contingent of his own men—German soldiers who had officially defected—to join Lee’s Americans. In a surreal display of solidarity, the American and German soldiers moved together toward the castle, their vehicles adorned with flags of truce and the shared purpose of saving the French captives.
The Battle Begins
When the joint force arrived at Castle Itter, they prepared for the inevitable. They knew the Waffen-SS would come to finish the job. As expected, on the morning of May 5, 1945, a sizable force of 100 to 150 SS soldiers arrived at the castle walls, armed with artillery, anti-tank guns, and the fanatical intent to slaughter the inhabitants.
The defense that ensued remains one of the most incredible footnotes of the war. U.S. tankers, Wehrmacht soldiers, and the French VIP prisoners (who had armed themselves with weapons left behind by the fleeing guards) fought from the ramparts. The Sherman tank Besotten Jenny was positioned to block the main entrance, while the defenders turned the castle into an improvised fortress. When the SS launched their assault, the air filled with the roar of 88mm anti-tank shells and small-arms fire. The Germans and Americans, who only hours before had been on opposite sides of a global conflict, were now shoulder-to-shoulder, passing ammunition, tending to each other’s wounds, and firing upon the SS.
A Tragic Cost
The defense was grueling. The SS pounded the castle with artillery, eventually destroying the Sherman tank and forcing the defenders to retreat further into the keep. In the heat of the firefight, Major Josef Gangl—the German officer who had crossed the line to join the Americans—was killed by a sniper’s bullet while attempting to move a wounded French prisoner to safety. He died fighting for the very people his army had intended to eliminate, becoming the ultimate symbol of the complexity of the battle.
As the defenders ran perilously low on ammunition and faced the prospect of being overrun by the fanatical SS, they managed to send one final desperate call to the American lines. Just as the enemy was preparing a final assault, reinforcements from the American 142nd Infantry Regiment arrived, catching the SS off-guard and scattering them into the surrounding woods. The prisoners were saved, and the battle, against all odds, ended in victory.
The Legacy of the Itter Stand
The Battle for Castle Itter is widely considered the only time during World War II that American and German soldiers fought as formal allies. It serves as a fascinating, jarring reminder that history is not always a binary of black and white. While the vast majority of the German military remained loyal to the end, the events at Itter highlight the internal fractures within the German war machine.
The battle is also a story of human nature in extremes. It shows that in the face of true fanaticism, the labels of “enemy” or “ally” can be discarded in favor of a shared sense of humanity. Captain Jack Lee Jr. was later awarded the Distinguished Service Cross for his actions, but the true legacy of Itter is the story of a German major, an American tank commander, and a group of French leaders coming together to protect the innocent from the abyss of total war.
In an era of historical revisionism, Castle Itter stands as a stubborn, indisputable truth: even in the darkest hour of the 20th century, there was room for the unexpected. It remains a cinematic, haunting, and deeply human chapter of the war—a story that feels too strange to be true, yet is etched into the records of the Second World War as a moment of genuine, if desperate, grace.
The story of the Battle of Castle Itter is not just about a tactical victory; it is a profound lesson on the fluidity of history. It invites us to consider how easily the narrative of war can shift and how quickly individuals, given the right circumstances, can bridge the deepest divides. The castle itself still stands today in the Tyrol region of Austria, a quiet witness to the day the impossible happened. For those who visit, it is a reminder of the day when the world was changing so fast that enemies became brothers, and the final shots of the war were fired in the defense of life, not the destruction of it.
Reflection on the Impossible
As we look back at the Second World War, we are often struck by the sheer scale of the suffering and the overwhelming nature of the conflict. However, it is the small, intimate stories—the ones that defy our expectations—that often tell us the most about the human spirit. The soldiers who fought at Itter were not trying to make history; they were trying to survive it. Their actions, born of necessity and moral clarity, remind us that the human capacity for courage and cooperation can emerge even in the most unlikely and desolate places.
The legacy of the Castle Itter engagement will continue to captivate historians and storytellers for decades. It is a story that refuses to be ignored, precisely because it challenges the comfort of our historical labels. It forces us to acknowledge that in the closing hours of the most destructive conflict in human history, there was one moment where the world didn’t just end with a whimper or a bang, but with a surprising act of defiance that brought enemies together in the name of a common, necessary humanity.
The soldiers and prisoners at Itter were participants in a singular, bizarre, and beautiful event. They showed us that the war was not just a conflict of nations, but a struggle for the soul of humanity, and that sometimes, the hardest battle to win is the one that forces us to break the rules we have lived by for years. May we always remember the lessons of that Austrian castle, and the courage it took to stand together against the rising tide of hatred.
