The claim that Poland attacked the Gleiwitz radio station was part of the pretext Nazi Germany used to justify its invasion of Poland on September 1, 1939, which began the Second World War in Europe. The "attack" was staged by SS men pretending to be Polish insurgents. They seized the station in the German border town of Gleiwitz (now Gliwice, Poland), broadcast a brief message in Polish and left behind the body of a murdered man dressed to look like a Polish attacker. Similar staged incidents took place along the border the same night. The deception was confirmed after the war by one of its organizers.

The claim

On the evening of August 31, 1939, German radio reported that Polish forces had attacked the Gleiwitz station. The next morning, as German forces crossed into Poland, Hitler told the Reichstag that Poland had attacked German territory with regular troops and that Germany was now returning fire. German propaganda presented the war as a defensive response to Polish aggression and persecution of ethnic Germans.

Origin

The operation, part of a larger plan sometimes called Operation Himmler, was organized by the SS security service under Reinhard Heydrich. At Gleiwitz, a small team led by SS officer Alfred Naujocks seized the station and broadcast a short anti-German statement in Polish. Because the station's equipment was limited, the broadcast was heard only locally. To provide evidence of a Polish attack, the SS brought a local man, Franciszek Honiok, a Silesian known for pro-Polish sympathies, drugged him and shot him, and left his body at the scene. At other staged incidents, prisoners from concentration camps were killed, dressed in Polish uniforms and left as evidence; the SS referred to them in code as "canned goods."

What the evidence shows

Naujocks's testimony. In a sworn affidavit in November 1945, used at the Nuremberg trials, Naujocks described receiving orders from Heydrich to simulate an attack on the station and explained how the operation was carried out.
Other testimony. Testimony from other German officials at Nuremberg corroborated the existence of staged border incidents intended to provide propaganda justification for the invasion.
Hitler's intentions. Records of Hitler's meetings with his generals, including on August 22, 1939, show that he had already decided to invade and told them he would provide a propaganda reason for starting the war, regardless of whether it was plausible.

Why it persists

The Gleiwitz incident is one of the best-documented examples of a "false-flag" operation, an attack staged to look as if it was carried out by an enemy to justify aggression. Because of this, it is frequently cited in discussions of later conflicts. It also shows that a pretext does not need to convince the world; it may be enough to give a domestic audience a story.

At the same time, the history of real false-flag operations is sometimes misused by conspiracy theorists, who claim that genuine attacks were staged. The Gleiwitz case is known because of documentary evidence and testimony, which is the standard such claims should meet.

Lessons for readers

Be skeptical when an aggressor claims to be responding to a sudden attack that conveniently justifies a planned war.
Ask who benefits from an incident and whether the response was prepared in advance.
False-flag operations are real but rare, and claims about them require strong evidence.
Propaganda aimed at a domestic audience does not need to persuade foreign observers.
Postwar testimony and documents can expose deceptions that were invisible at the time.
