On a quiet Munich morning in October 1957, a man walked to work just like any other day. No threats, no warnings, no chase. Within 60 seconds, he was dead on the stairwell floor. No gunshot wound, no blood, no signs of struggle. To every detective who examined the body, it looked like a simple heart attack, but it wasn’t.
It was a ghost killing engineered inside the darkest laboratories of the Soviet KGB, and the weapon used a custom-built pistol that fired a mist of cyanide directly into a man’s face, dissolving into his bloodstream so fast that by the time his heart stopped, the evidence had already evaporated. The victim’s name was Lev Rebik, and his story doesn’t begin with his death.
It begins with one of the most violent summers in the history of World War II. In a city where the streets ran with blood and the screams of thousands echoed off stone walls. If you’ve never heard of Lev Rebik, that’s exactly why this channel exists. Stay with us, because this story is going to hit different.

The city of Lviv in western Ukraine has just been seized by Nazi Germany, but before the German boots even settle into the streets, the population discovers something that changes everything.
In the city’s prisons, the same prisons where the Soviet NKVD had operated for nearly two years, the walls are stained with blood. Hundreds of bodies are piled in courtyards and corridors. Men, women, and teenagers, their hands tied behind their backs, shot in the back of the head.
The NKVD, in the chaos of the German advance, had systematically massacred political prisoners before retreating. Most of the dead were Ukrainian. The discovery triggers a fury unlike anything the city had seen. Within hours, a narrative spreads through Lviv like wildfire, and it is deliberately engineered. Ukrainian nationalist militias working alongside all own the organization of Ukrainian nationalists begin pointing fingers at the Jewish population, falsely accusing them of collaborating with the Soviet executioners. It was propaganda. It was
a lie. But in a city overwhelmed by grief, rage, and fear, lies travel fast. What followed over the next 2 weeks was a massacre. Men were dragged out of homes and shot in the street. Women were stripped, beaten, and subjected to unspeakable acts of violence in public with crowds watching. Children were not spared.
The German Einsatzgruppen, the Nazi mobile death squads, arrived and joined the slaughter. But historians are clear. The initial wave of violence was ignited by OUN affiliated units and local collaborators. By the time it was over, thousands of Jewish civilians had been murdered in what became known as the Lviv pogroms of 1941.
Two separate waves of killing, and at the center of the political machinery driving it all was a name that history is largely forgotten, Lev Rebet. Serving at that moment as deputy prime minister of a freshly declared Ukrainian government. Who was Lev Rebet? That question is more complicated than it first appears. He was born on March 3rd, 1912 in the Ukrainian town of Stryi, a mid-size city in what was then the Austro-Hungarian Empire.
His father, Mykhailo Rebet, was a postal official. His mother, Kateryna Nadokizi, ran the household. By all accounts, they were a stable, respectable middle-class family. But the world around young Lev was anything but stable. By the time Lev was 6 years old, the Austro-Hungarian Empire had collapsed. World War I had redrawn every border in Eastern Europe.
Stryi, his hometown, was suddenly part of the newly restored Polish Republic, and Ukrainian identity, culture, and language were once again under pressure from a foreign government. That tension shaped him. At 15 years old, an age when most boys are worrying about school exams, Lev Rebet joined the Ukrainian Military Organization.
By the time he was 18, after the OUN was formally established in 1929, he was already heading its leadership in the Stryi district. He wasn’t a follower, he was a builder, and he was brilliant enough to pursue a law degree at Lviv University simultaneously, graduating from its law faculty in 1938, even after multiple arrests by Polish authorities.
Those arrests are worth understanding. In 1934, Poland’s Interior Minister Bronisław Pieracki was assassinated in Warsaw, one of the most high-profile political murders in pre-war Europe. The OUN was responsible. Rebet was arrested alongside Stepan Bandera and other senior OUN figures. He was released due to lack of direct evidence, but his association with the organization was now public record.
What’s remarkable is that despite prison time, surveillance, and the constant threat of prosecution, Rebet never slowed down. He wrote propaganda for the OUN’s publications. He built networks. He even found his wife, Daria, within OUN ranks, a woman who shared his convictions and stood by him through years of political chaos.

Together, they had two children, a son, Andriy, and a daughter, Oksana. This was not a man driven purely by ideology. He was a father, a legal scholar. To him, he believed, genuinely, that Ukraine deserved to exist as a free nation. That belief would define and ultimately end his life. September 1st, 1939, Germany invades Poland.
Within weeks, the Soviet Union moves in from the east. Poland is partitioned. Western Ukraine falls under Soviet control and the NKVD begins its brutal campaign of arrests, deportations, and executions against anyone considered a political threat, including Ukrainian nationalists. Rebet escapes to Krakow, now inside German-occupied territory, and continues organizing.
When Germany invades the Soviet Union on June 22nd, 1941, OUN leaders see their moment. Here, finally, is the chaos they can exploit to declare Ukrainian independence. On June 30th, 1941, as German forces enter Lviv, OUN leader Yaroslav Stetsko reads a declaration of Ukrainian statehood. Lev Rebet stands beside him, appointed deputy prime minister of this brand new government that exists for barely 2 weeks before the Germans shut it down.
Because here’s what the OUN had miscalculated. Hitler had no interest in an independent Ukraine. He wanted Ukrainian territory, Ukrainian resources, and Ukrainian labor, not a sovereign Ukrainian state. Within weeks, the Gestapo was arresting OUN leaders. Stetsko was detained. Bandera was sent to Sachsenhausen concentration camp.
And Lev Rebet? In September 1941, he was transported to Auschwitz. Let that sink in. The deputy prime minister of a would-be Ukrainian government was imprisoned in the most infamous death camp in history by the same regime he had hoped would support Ukrainian independence. He remained there until October 1944, 3 years inside Auschwitz.
He survived when millions did not. When Rebet walked out of Auschwitz in 1944, the world had changed completely. The Red Army was sweeping westward. Any dream of a German-supported Ukrainian state was gone, and returning to Soviet Ukraine meant certain arrest, or worse. So, Rebet rebuilt his life in Munich, in the American occupation zone of West Germany.
Munich had become the unlikely hub of Ukrainian intellectual exile, filled with writers, lawyers, former soldiers, and political thinkers who had escaped Soviet territory and refused to go silent. In those post-war years, Rebet evolved. He moved away from the radical nationalism of his younger years, and became one of the more moderate, intellectually serious voices in the Ukrainian immigrant community.
He wrote extensively, analyzing Soviet totalitarianism, documenting the deportation of Ukrainians, the destruction of Ukrainian language and church institutions inside the USSR. His work reached out aspora communities across the United States, Canada, and Western Europe. In 1948, he even had the courage to break with Stepan Bandera, opposing Bandera’s authoritarian leadership style within the OUN.
By 1954, that split was final and permanent. In an exile community filled with old loyalties and bitter feuds, taking a stand against Bandera took genuine nerve. But that independence, that willingness to operate outside Moscow’s narrative and outside Bandera’s control, made Rebet dangerous in the eyes of the KGB. Inside KGB headquarters in Moscow, a special department known as Department 13, responsible for wet work, the Soviet euphemism for assassination, was developing something new.
They needed a method to eliminate enemies abroad that left no forensic trace, no bullet, no poison residue, no evidence of foul play. Their solution was a custom-designed spray pistol that fired a pressurized burst of hydrogen cyanide, a colorless, fast-acting gas. Inhaled directly into the lungs, it would trigger cardiac arrest within minutes.
By the time the body was found, the compound had already metabolized. To any coroner, the death looked entirely natural. The agent selected to carry out the mission was Bohdan Stashynsky, a Ukrainian-born KGB operative who had already demonstrated his willingness to kill. Stashynsky was meticulous, calm under pressure, and ideologically compliant.
He was given the weapon, the target’s routine, and a window of opportunity. On the morning of October 12, 1957, Lev Rebet left his Munich apartment and walked toward his office, where he was scheduled to meet colleagues to work on articles. He was 45 years old. He had survived Polish prisons, Nazi concentration camps, and years of Cold War exile.
He had outlasted empires. He did not outlast the stairwell. Stashynsky intercepted Rebet in the staircase leading to his office. He raised the concealed weapon. He fired a single burst of cyanide gas directly into Rebet’s face. Rebet collapsed. When colleagues found him minutes later, there was no sign of violence, no struggle, just a middle-aged man who appeared to have suffered a sudden heart attack.
Munich police and the medical examiner confirmed it. Natural causes. Heart failure. The KGB had pulled off a perfect ghost murder, and they knew it. Because just 2 years later, in 1959, Stashynsky used the exact same method to assassinate Stepan Bandera in the same city. The truth might never have come out, but in 1961, Stashynsky did something the KGB never predicted. He defected.
He crossed into West Germany with his East German wife, walked into a police station and confessed to both murders. The Rebet killing, the Bandera killing, the weapon, the orders, the KGB chain of command that stretched directly back to Moscow. The trial that followed became an international [clears throat] sensation.
West German courts convicted Stashinsky of both murders, but in a landmark legal decision, the judges ruled that the primary responsibility lay not with the triggerman, but with the Soviet state that ordered and engineered the killings. Stashinsky received a reduced sentence. The moral and legal indictment fell on Moscow. It was one of the first times a Western court had formally attributed political murder to the Soviet government by name.
The case made headlines around the world and forced intelligence agencies across NATO to rethink how vulnerable their assets were to Soviet covert action. Lev Rebet’s story is not simple. He was, in the same lifetime, a political prisoner and a government official during a pogrom, a concentration camp survivor and a nationalist organizer who bore responsibility for the machinery of violence in Lviv in 1941, the serious legal scholar and a Cold War target who died on the staircase in Munich without ever seeing the free
Ukraine he had spent his entire life working toward. History doesn’t give us clean heroes, but it does give us truth if we’re willing to go looking for it. The KGB thought killing him in silence would erase him. Instead, the exposure of his murder became one of the defining espionage scandals of the Cold War, and his name is still being debated by historians today.
Ukraine eventually gained its independence in 1991, 34 years after a Soviet gas pistol ended Lev Rebet’s life on a Munich staircase. He never saw it, but the story survived, and now so does his name. That’s the story of Lev Rebet, deputy prime minister, Auschwitz survivor, and victim of one of the most sophisticated assassinations in Cold War history right here on Untold War Stories.
