Reinhard Heydrich never lived to see the end of World War II. He died in Prague in June 1942 after an attack by Czechoslovak agents in what became known as Operation Anthropoid. His early death meant he never witnessed the collapse of Nazi Germany, capture by the Allies, or the post-war war crimes trials.
Had Heydrich survived until 1945, it is highly likely he would have been arrested, tried, and executed. He would probably have been considered one of the most important Nazi prisoners ever captured. He was not merely a senior SS officer serving under Heinrich Himmler. He was one of the chief architects of the Nazi security state and played a major role in persecution, mass murder, and the development of the Holocaust.
Surviving documentary evidence links him directly to these crimes. This would have made his defense extremely difficult. Born in 1904, Heydrich joined the SS in 1931 and rose with astonishing speed. Himmler recognized his intelligence and organizational ability and placed him in charge of the SS intelligence service, known as the Sicherheitsdienst, or SD.
As Nazi power expanded, so did Heydrich’s authority. He eventually became head of the Reich Main Security Office, commonly known by its German abbreviation RSHA. This organization was created in 1939 and brought together some of the most feared institutions within Nazi Germany. Under Heydrich’s authority were the Gestapo, the criminal police, and the SD intelligence service.
This gave him enormous influence over the mechanisms used to identify, arrest, imprison, deport, and ultimately kill those considered enemies of the Nazi regime. This would have been highly significant during any post-war trial. Heydrich could not easily claim he was just an ordinary soldier following orders. He held one of the highest positions within the SS security system. He helped set policy, issued instructions, and oversaw the organizations that carried them out.
One of the most serious charges against Heydrich would have involved the Einsatzgruppen, the mobile killing units. When Germany invaded the Soviet Union in June 1941, special SS and police units followed the German armies eastward. Their activities in the Soviet Union turned into a massive program of mass murder. They targeted communist officials, persecuted people, and others the Nazis considered enemies.
Soon, the killings expanded to include entire communities. Men, women, and children were taken from their homes, forced to march or be transported to execution sites, and then shot. Hundreds of thousands of people had been killed this way by the time Heydrich died in 1942. He was a man deeply connected to this system. The Einsatzgruppen operated through the SS and security police structure over which he held immense power.
Orders, reports, and communications passed through organizations controlled by the RSHA. Heydrich stood near the top of the command structure responsible for some of the largest massacres committed during the early stages of the Holocaust. Had he been captured at the end of the war, Allied prosecutors would certainly have considered his actions a major part of their case against him.
Extensive documentary evidence would also have been available. Nazi Germany produced enormous amounts of paperwork. Although many documents were deliberately destroyed as Germany collapsed, huge numbers survived. Orders, reports, correspondence, and meeting records allowed Allied investigators to reconstruct the activities of Nazi organizations. Heydrich’s name appeared throughout this bureaucratic machine.
Perhaps the most famous example was the Wannsee Conference. On January 20, 1942, Heydrich gathered representatives from several German government ministries and Nazi organizations at a villa beside Lake Wannsee near Berlin. The subject was the Final Solution. The conference was not the beginning of the Holocaust. Jews were already being killed on a massive scale, especially in the occupied Soviet territories.
Instead, the meeting was meant to coordinate the various branches of the German state in the deportation and destruction of the Jewish population of all Europe. This would have been damning evidence in a post-war trial. The surviving Wannsee Protocol proved that Heydrich was not a distant official who could claim ignorance of what was happening. He was personally coordinating with senior officials involved in implementing Nazi racial policy across Europe.
His authority also came directly from the highest levels of the Nazi government. In July 1941, Hermann Göring delegated to Heydrich the task of making preparations for a comprehensive solution to the so-called Jewish question in German-controlled Europe. Heydrich occupied a highly central position between Nazi ideology and its practical implementation.
His behavior in occupied Czechoslovakia would have given prosecutors another major area to examine. In September 1941, he was appointed acting Reich Protector of Bohemia and Moravia. Hitler and other Nazi leaders believed German control over those territories needed to be strengthened, especially because Czech industry was important to the German war effort.
Heydrich responded with a combination of economic measures and brutal repression. Thousands of people were arrested, resistance networks were attacked, and executions were carried out as warnings to the population. He wanted to destroy organized resistance while ensuring Czech factories continued producing weapons and equipment for Germany. His reputation became so feared that the Czechoslovak government-in-exile supported an operation to assassinate him.
On May 27, 1942, Czechoslovak paratroopers Jozef Gabčík and Jan Kubiš attacked Heydrich as he passed through Prague. The operation was organized with British help and became known as Operation Anthropoid. Heydrich was severely wounded. At first, he appeared likely to survive, but his condition worsened. He died on June 4, 1942, at the age of 38.
His death saved him from experiencing the destruction of the regime he served. Had Heydrich lived another three years, his fate might have resembled that of Ernst Kaltenbrunner. Kaltenbrunner eventually became head of the RSHA after Heydrich’s death. He survived the war and was captured by American forces in 1945. He then stood before the International Military Tribunal at Nuremberg.
Kaltenbrunner tried to distance himself from some of the crimes connected to the security organizations under his authority. However, prosecutors presented extensive evidence regarding the activities of the RSHA and the SS security systems. He was convicted of war crimes and crimes against humanity. On October 16, 1946, Ernst Kaltenbrunner was executed by hanging inside Nuremberg Prison.
The comparison between Kaltenbrunner and Heydrich is highly significant. If Kaltenbrunner received the death sentence for his role as head of the RSHA, Heydrich would have been in an extremely dangerous position. Heydrich helped build and expand the very system that Kaltenbrunner later inherited. Heydrich might have appeared alongside Hermann Göring, Joachim von Ribbentrop, Wilhelm Keitel, and other senior Nazi defendants in the main Nuremberg trial.
The charges against him would have been extensive. Prosecutors could have examined his role in the Gestapo and SD, his relationship with the Einsatzgruppen, the persecution and deportation of Jews, repression in occupied territories, mass executions, and his involvement in coordinating the Final Solution. There might also have been evidence relating to events that occurred even before the war.
Heydrich was involved in the Nazi security apparatus during preparations for the invasion of Poland in 1939. SS and security personnel took part in staged incidents designed to portray Germany as the victim of Polish aggression. These operations formed part of the broader propaganda preparations surrounding Hitler’s attack on Poland. This would have strengthened the argument that Heydrich was involved not only in wartime atrocities but also in the machinery surrounding Nazi Germany’s aggressive expansion and the outbreak of the war itself.
It is impossible to state with absolute certainty what verdict a court would have reached, because Heydrich never stood trial. No defendant can legally be judged until evidence is presented and judges reach a final decision. However, comparison with other Nazi leaders makes the outcome exceptionally clear. Death sentences were handed down to men who had far less influence over the Nazi apparatus of repression.
Heydrich was one of the most powerful men within the SS and one of the central figures in Nazi Germany’s security apparatus. His major problem would have been the vast documentary record linking him to that system. He was not merely someone standing near the decision-makers. He was himself a decision-maker. He chaired meetings, issued instructions, led organizations, and coordinated policies.
Had he sat in the dock at Nuremberg, prosecutors could have presented documents bearing his name to the judges and linked him directly to the organizations responsible for mass murder. He might well have become one of the most important defendants in the entire trial. Heydrich possessed exceptional knowledge of the inner workings of the Nazi state. If captured alive, Allied investigators would have sought information from him about Himmler, the SS, the Gestapo, the SD, the mobile killing units, and the development of the Holocaust.
But once his trial began, that knowledge would not have protected him from responsibility for his own actions. Reinhard Heydrich died three years before the collapse of the Nazi German state. In doing so, he escaped the courtroom where many surviving leaders of the regime were forced to answer for their crimes. Had he remained alive until 1945, the evidence against him would likely have placed him among the most important Nazi war criminals to be tried. That would inevitably have led to a sentence of death.
