Nikolaus Ernst Hornig, known as Klaus, was a German police officer and lawyer who, in the autumn of 1941 in occupied Poland, refused to carry out an order to execute Soviet prisoners of war. He invoked Paragraph 47 of the military penal code, which granted soldiers the right to disobey an order if they recognized it as a crime. This stance cost him many years in prison and internment in a concentration camp, but made him one of the few documented cases of successful disobedience within the structure of the Third Reich.
The Path of a Catholic Lawyer
Klaus Hornig was born in December 1907 in Świebnica, Silesia, into a family with strong Catholic traditions. His father, a dentist, sympathized with the centrist Centre Party, and Klaus himself was active in the Catholic youth movement in his youth. These formative experiences shaped his later value system, which clashed with the reality of Nazi Germany. He studied law and political science at the universities in Wrocław and Königsberg, where he joined Catholic student corporations.
The Great Depression, however, forced him to discontinue his studies in 1930 when the family lost their financial means. Hornig then decided to join the Prussian Protective Police as an officer candidate — a pragmatic path to a stable life that ironically would lead him to the front lines of Hitler’s ideological war. In 1934, he was commissioned as a police lieutenant and transferred the following year to the newly forming Wehrmacht.
Hornig’s academic ambition did not fade despite his uniformed service. While stationed in Munich and Innsbruck with the 2nd Mountain Division in 1938–1939, he continued his legal studies and passed the first state exam at the University of Innsbruck. He later earned his doctorate in law at the University of Marburg. This legal background proved crucial when facing the moral and legal dilemma of an infamous order. His knowledge of the law armed him with arguments where others saw only ruthless compulsion.
The Death Order
In the autumn of 1941, Hornig received orders to transfer to Lublin in the General Government, where he was to take command of a company in Police Battalion 306. This unit was part of the occupation police forces involved in the extermination campaign against Jews, Polish partisans, and civilians in the occupied territories. The battalion was under the infamous Odilo Globocnik, SS and police commander of the Lublin district, responsible for mass murders under Operation Reinhardt.
On November 1, 1941, Hornig was given the order to shoot Jews and Soviet political commissars in accordance with the so-called Commissar Order from October that year. At that moment, he made a decision that changed his life — he refused to carry out the order, invoking Paragraph 47 of the military penal code. This regulation granted a soldier the right to defy an order if it constituted a crime. Hornig believed he had not only the right but also the duty to protect himself and his subordinates from criminal acts.
The command’s response was immediate and harsh. Hornig was suspended from duty and sent back to his base in Frankfurt am Main. His attitude was an exception among the thousands of German policemen and soldiers who carried out similar orders without objection.
Historical research shows that refusal to commit killings was possible and did not always result in a death sentence, although it required tremendous moral courage. Hornig paid for his decision with years of imprisonment and persecution.
Trials, Imprisonment, and Silence
The Gestapo arrested Hornig on April 28, 1942, on charges of undermining military discipline in the Wehrmacht. The first trial took place before the SS and Police Court in Kassel, presided over by SS General Josias Prince of Waldeck and Pyrmont. He was sentenced to six years and seven months in prison, but the sentence was conditionally suspended after Hornig’s appeal. There was one condition: complete silence about what he had witnessed on the Eastern Front.
Hornig did not abide by the imposed obligation of silence. Upon returning to Frankfurt, he spoke in detail about the crimes he had witnessed in the East. This behavior showed his deep conviction that the truth about the atrocities had to come to light.
Consequences followed in February 1945, when he faced another court. He was found guilty of military disobedience and crimes, and was ordered interned in a concentration camp.
The justification for the March 15, 1945, verdict is a document illustrating the mechanisms of the totalitarian state. The court claimed that Hornig had violated the obligation of secrecy, and that his accounts posed a particular threat to the security of the Reich. Even in self-defense, he was not permitted to share his experiences with third parties. He was sent to Buchenwald concentration camp, where he lived to see liberation by American forces. He survived, but his fight for justice was just beginning.
Witness to Crimes
After his liberation from Buchenwald, Hornig was detained by the Americans in internment camps and interrogated as a witness to war crimes, including mass shootings in the East. His testimony was a valuable source of insights into the mechanisms of extermination carried out by police units. He only left the Dachau camp (then a place of Allied internment and denazification) in September 1947.
Hornig’s post-war efforts to rehabilitate himself and obtain compensation brought mixed results. In 1953 he was promoted to lieutenant colonel of police, but was at the same time retired. As he bitterly noted himself, others advanced without obstacles while he was refused a return to active service. His applications to the Border Guard and the newly formed Bundeswehr were refused, reflecting postwar reluctance to honor those who had opposed criminal orders.
In the 1960s and 1970s, Hornig played an important role as an expert witness in trials against former Ordnungspolizei officers. He especially testified in cases concerning the so-called defense of superior orders — the argument that the accused had to follow orders under threat of their own death. His case proved that refusal was possible, though it brought serious consequences.
He died in Munich in December 1997, a day after his ninetieth birthday, as one of the few documented examples of moral resistance within the Nazi German system.

Rory's grandfather left behind a wartime diary filled with accounts of a minor Burma skirmish that history books never mentioned. Reading it, Rory realized: behind every famous battle are dozens of forgotten struggles, each with its own human drama.
His preferred topics: The overlooked corners of military history – secondary campaigns, shadow battalions, local conflicts that never made headlines. From medieval sieges to twentieth-century expeditions, he focuses on the soldiers, not the generals. The people who faced impossible choices and carried those experiences forever.
Rory strips away the romanticism without losing respect for those who served. He combines tactical analysis with personal stories, examining human endurance and moral complexity rather than celebrating warfare. His writing is balanced, thoughtful, and deeply researched.
Outside work, Rory visits forgotten battlefields (now quiet farmland), photographs war memorials nobody tends anymore, and interviews veterans' families.
