On 10 August 1939,
Reinhard Heydrich informed Naujocks of his mission to lead a small group of German operatives to seize the Gleiwitz radio station. Three weeks later, on the night of 31 August, Naujocks led the
attack on the German radio station at Gleiwitz, one of twenty-one similar concentrated attacks which the German government quickly attributed to the
Poles. Once inside the radio station, a short
anti-German message in Polish was broadcast (the precise content of the message is now uncertain). Shots were fired in the studio and a corpse left on the floor near the microphone. This attack formed Hitler's justification to the Reichstag regarding the necessary "pacification" of Poland, thereby igniting the
Second World War in Europe. More recently, author and researcher
Jak Mallmann Showell's investigation has suggested that Naujocks' claims as to his actions at the Gleiwitz radio station may have been a fabrication to curry special handling by the Allies after the war. Mallmann Showell discerned that Naujocks is the sole source for details of his personal actions on the night of 31 August 1939. He also that the Poles may have accessed the site to obtain
Enigma machine secrets for the Allies. General Lahousen confirmed he provided Naujocks the Polish uniforms. Later, on 9 November 1939, Naujocks (along with
Walter Schellenberg) participated in the
Venlo incident, which saw the capture in the
Netherlands of two British
SIS agents, Captain
Sigismund Payne Best and Major
Richard Henry Stevens. For this, he was personally awarded the Iron Cross by Hitler. Naujocks also assisted Schellenberg in the secret assignment of spying on Berlin brothel
Salon Kitty's clientele. In early 1940, Naujocks was put in charge of the counterfeiting unit of the SD charged with forging British bank notes under
Operation Andreas. By late 1940, Naujocks had been removed from his position after he fell out of favour with Heydrich.In 1941, he was dismissed from the (SD) after disputing one of Heydrich's orders. He was demoted and had to serve in the
Waffen-SS on the Eastern Front. In 1943, due to ill health, he was sent to the West, where he served as an economic administrator the following year for German troops in
Belgium, while involving himself in the deaths of several Belgian underground and
Danish resistance members. After his promotion to SS- () he participated in sabotage and terrorist actions against the Danish population from December 1943 until autumn 1944, as the leader of the "Peter Group", including the murder of Lutheran pastor
Kaj Munk. Later leadership passed to SS- Otto Alexander Friedrich Schwerdt (). Around November 1944 Naujocks turned himself over to US forces, who subsequently placed him in detention as a possible
war criminal by the end of the war. ==Later life==
