Gleiwitz radio attack as Polish aggression
01
What institutions accepted
Nazi German authorities staged the seizure and Polish-language broadcast at the Gleiwitz radio station and presented it within a broader narrative of genuine Polish aggression against German territory.
02
What the evidence supports now
The Gleiwitz incident of 31 August 1939 was a German security-service operation ordered by Reinhard Heydrich, not a Polish attack. Alfred Naujocks later stated under oath that Heydrich ordered him to simulate an attack, make the attackers appear Polish and provide practical evidence for the foreign press and German propaganda. Germany invaded Poland the following morning, but the invasion had already been planned; Gleiwitz was a manufactured pretext within the aggression narrative, not the event that caused the decision to invade.

In his sworn statement dated 20 November 1945, Naujocks says Heydrich personally ordered him to simulate a Polish attack at Gleiwitz, make the attackers appear Polish and produce practical evidence for the foreign press and German propaganda. It documents the accusation's manufacture; it does not support the truth of the alleged Polish attack.

04
Impact
Gleiwitz illustrates a deliberately manufactured factual episode being fed into state justification for military aggression. A small German security-service team seized the radio station, transmitted briefly in Polish and fired shots before leaving. On 1 September Hitler publicly portrayed Germany as responding to Polish attacks on German territory. The operation supplied staged evidence for a policy already chosen rather than triggering that policy.
Context
Hitler did not name Gleiwitz in his 1 September Reichstag speech. He made the broader claim that Polish regular soldiers had fired on German territory and that Germany was returning fire.
The Reich Security Main Office (RSHA) did not yet formally exist in August 1939; it was created only on 27 September 1939. The strongest primary evidence identifies Heydrich as chief of the Security Police and SD.
Popular retellings often add details about Polish uniforms or identify the unconscious man delivered to Naujocks as a particular victim. Those details go beyond what Naujocks's sworn statement directly establishes and are not necessary to demonstrate the staged attack and its propaganda purpose.

Institutional episode 01
Nazi Germany
Europe
Gleiwitz was not a mistaken border report. Heydrich ordered a German security-service team to create an apparent Polish attack and explicitly linked the operation to press and propaganda needs. The staged broadcast occurred on 31 August 1939; the next day Hitler publicly claimed that Polish forces had fired on German territory while Germany invaded Poland. The incident therefore qualifies as institutionally adopted fabrication, but its causal role must remain narrow: it furnished apparent evidence for an aggression narrative rather than determining the invasion.
Institutions involved
- Office of the Chief of the Security Police and SD under Reinhard Heydrich
- Reich government
Institutional context
Naujocks stated that around 10 August 1939 Heydrich personally ordered him to simulate an attack on the Gleiwitz radio station so that the attackers would appear Polish, explaining that practical proof was needed for the foreign press and German propaganda. Naujocks went to Gleiwitz with five or six other SD men and carried out the operation on the evening of 31 August. His team seized the station, used an emergency transmitter for a short Polish-language broadcast, fired pistol shots and left. On 1 September, as German forces invaded Poland, Hitler told the Reichstag that Polish regular soldiers had fired on German territory and presented German military action as a response. German Federal Archives material identifies Gleiwitz and other border incidents as Nazi fabrications used as ostensible justification for an invasion that had already been planned.
Why this persisted
PublicationGerman security services manufactured a border incident and the Reich government incorporated alleged Polish attacks into public propaganda presenting German military action as defensive retaliation.
How correction happened
UndocumentedThe reviewed evidence does not document an institutional retraction by Nazi Germany before the regime's collapse. Sworn postwar testimony and the German Federal Archives later identified the operation as fabricated; those are external findings, not a self-correction by the original carriers.
Consequences
- Creation of fabricated evidence intended for foreign press and German propaganda
- Incorporation of staged border incidents into the official narrative that Poland had attacked German territory
- Public presentation of German military action as defensive retaliation rather than planned aggression
- Use of a manufactured incident as one element of the propaganda justification surrounding the invasion of Poland

- DocumentsInstitutional carrierAffidavit of Alfred Helmut Naujocks — PS-2751Harvard Law School Library Nuremberg Trials Project
Where in the source: PS-2751, affidavit §§ 1–2 (printed p. 390)
Naujocks identifies himself as an SD member and Heydrich as chief of the Security Police and SD, then attributes the order and the assignment of five or six SD men directly to Heydrich. The record therefore names the contemporary office rather than the not-yet-created RSHA.

Where in the source: PS-2322, printed pp. 1028 and 1030, especially the “Last night” paragraph on p. 1030
Hitler's speech documents the publication side of the mechanism by turning alleged Polish frontier incidents and gunfire into a public claim of defensive German retaliation. It supports the broader narrative, not a claim that Hitler mentioned Gleiwitz by name.

Hitler's 1 September speech publicly asserted that regular Polish soldiers had fired on German territory and presented German action as returning fire. This directly documents the official defensive-retaliation narrative, while the separate Bundesarchiv source establishes that the claim was false.
- SupportsConsequencesThe German invasion of Poland in 1939German Federal Archives
Where in the source: “Einführende Informationen,” second paragraph
The archive links the fabricated border incidents, including Gleiwitz, to their use as pretexts for the invasion and contrasts Hitler's public retaliation claim with the longer-standing invasion plan. This supports the causal scope stated in the record: propaganda justification, not the decision to invade.

Where in the source: “Einführende Informationen,” first two paragraphs; “Primäre Überlieferung,” opening paragraph
The guide dates the opening attack to about 4:47 a.m. on 1 September and identifies the prewar “Case White” planning record. It provides chronology and planning context rather than evidence for Naujocks's detailed operational account.

Where in the source: PS-2751, affidavit §§ 5–6 (printed p. 391)
For the Gleiwitz operation, Naujocks describes an unconscious, unidentified man in civilian clothes and does not identify him by name. Keeping the record to what the affidavit states avoids importing details from other staged border incidents or later popular retellings.

Where in the source: Opening paragraphs and “Formation of the Reich Security Main Office (RSHA)”
The US Holocaust Memorial Museum dates the RSHA's creation to 27 September 1939 and explains that it formally linked the Security Police and SD under Heydrich. This supports the record's refusal to retroactively name the RSHA as the August carrier.
- ContextualizesInstitutional correctionThe German invasion of Poland in 1939German Federal Archives
Where in the source: “Einführende Informationen,” second paragraph
The Federal Archives' later identification of the lie and fabrication is an external postwar finding. It does not document a retraction by the Nazi institutions that carried the narrative, so the correction status remains “undocumented” rather than converting the archival account into a self-correction.
