The Nun Who Poisoned 50 SS Officers with Soup During Sunday Lunch
On a quiet Sunday morning in March 1945, in a convent kitchen nestled in occupied Poland, a remarkable act of defiance was about to unfold. Sister Maria Antonyina, a 52-year-old nun, stood before a massive iron pot, stirring a golden vegetable soup meant for 50 high-ranking SS officers. The aroma of carrots, potatoes, and celery filled the air, but hidden beneath her gray habit, tucked inside a small cloth pouch at her waist, was a vial of rat poison. In just a few hours, she would commit one of the most audacious acts of resistance in World War II history.
The Context of War
To fully grasp the gravity of Sister Maria’s actions, we must rewind to 1939, when the world as she knew it began to crumble. Poland, caught between Nazi Germany and Soviet Russia, became one of the bloodiest battlegrounds of the war. The convent of the Sacred Heart in Posen, where Sister Maria had spent decades serving the community, transformed from a sanctuary of peace into a prison for her and her fellow nuns. The Nazis repurposed the convent into a rest facility for SS officers, men who had overseen atrocities and committed unspeakable acts against humanity.
For five long years, Sister Maria witnessed the horrors of war firsthand. She prepared meals for the very men who laughed about their conquests, who shared stories of villages burned and families executed. The convent, once a place of healing, had become a monument to evil. Each day, she prayed for deliverance, but as the war dragged on, the silence from heaven was deafening.
The Turning Point

The turning point came in January 1945 during one of the coldest winters Poland had ever seen. Margareta watched in horror as a group of Jewish prisoners, skeletal and freezing, were marched past the convent. When one young woman collapsed in the snow, an SS officer shot her without hesitation. That moment shattered something within Sister Maria. It was then she realized that her silence and obedience had become acts of cowardice.
Determined to take action, she began to plan. She understood the risks involved but felt that inaction would lead to more suffering. On the second Sunday of March, she decided to prepare her famous vegetable soup, but this time, she would add a lethal ingredient.
The Plan
Sister Maria meticulously planned her act of resistance. She studied the officers’ routines, noting when they gathered for their communal Sunday lunch. The officers would be present in large numbers, making it the perfect opportunity to strike. The poison she chose, arsenic triioxide, was readily available in the convent basement, used to control the rodent population.
Calculating the dosage carefully, she poured the poison into the soup, knowing that if all 50 officers consumed it, the results would be catastrophic. The stakes were high, and the risks immense; if even one officer suspected foul play, the consequences would be dire.
The Execution of the Plan
On the morning of March 11, 1945, Sister Maria awoke with a sense of purpose. As she prepared the soup, she felt the weight of her decision pressing down on her. This was no longer about revenge; it was about justice. By noon, the officers began arriving for their Sunday lunch, unaware that their fate was sealed.
As the soup was served, the atmosphere in the dining hall was jovial. The officers laughed and toasted to their victories, oblivious to the impending doom. Sister Maria watched from the kitchen doorway, her heart pounding as she listened to their laughter. But soon, the first signs of distress appeared.
The Chaos Unfolds
Within minutes of consuming the soup, the first officer stood up, clutching his stomach. The laughter faded, replaced by confusion and fear. One by one, the officers began to realize that something was terribly wrong. Panic erupted in the dining hall as men began to vomit and collapse.
Sister Maria retreated into the kitchen, her heart heavy with the weight of what she had done. She had poisoned 50 men—men who had participated in unspeakable acts against humanity. The chaos outside was a cacophony of screams and panic, and she knew her life as she had known it was over.
The Aftermath
The SS officers who survived the initial wave of poisoning were left to grapple with their fate. In total, 47 of the 50 officers died due to the poison. The news of the incident spread quickly, and the consequences were immediate. The SS retaliated by rounding up 200 male civilians from the surrounding area and executing them in the town square. It was a brutal reminder of the lengths to which the Nazis would go to maintain control and instill fear.
Sister Maria understood that her actions had led to the deaths of innocent people, and the guilt weighed heavily on her conscience. She had acted out of desperation, out of a desire to stop the atrocities, but the price was steep.
The Escape
In the chaos that followed the poisoning, Sister Maria knew she had to escape. She had prepared a plan months in advance, hiding civilian clothes and forged documents in anticipation of this moment. As the SS searched for her, she slipped away from the convent, navigating through the hidden passageways only she knew.
Emerging into the daylight, she felt a rush of freedom mixed with fear. The countryside was crawling with German patrols, and she had to move quickly. Each step was a gamble, a risk that could lead to capture or death. But she pressed on, determined to survive and ensure her story was told.
A New Beginning
After a harrowing journey, Sister Maria finally reached the Allied lines. Exhausted but resolute, she shared her story with British intelligence officers, detailing her actions and the events that had unfolded at the convent. They were stunned by her bravery and the audacity of her plan.
Despite the chaos of the war, Sister Maria found a sense of purpose in her survival. She had taken a stand against evil, and while the consequences had been tragic, she believed that her actions had saved countless lives.
Conclusion
Sister Maria Antonyina’s story is one of courage, sacrifice, and the complexity of human morality in times of war. She was not a soldier or a spy; she was a nun who had dedicated her life to service. Yet, when faced with unimaginable evil, she chose to act. Her legacy serves as a reminder that even in the darkest times, individuals can make choices that reflect the best of humanity.
In a world often defined by conflict and division, Sister Maria’s story challenges us to consider the power of compassion and the importance of standing up against injustice, no matter the cost. Her act of defiance, though shrouded in moral ambiguity, remains a testament to the resilience of the human spirit and the enduring fight for justice.
