On 10 August 1939, Reinhard Heydrich directed Naujocks of his mission to lead a small group of German operatives to seize the Gleiwitz radio station.[7] Thereafter, on the night of 31 August, Naujocks led the attack on the German radio station Gleiwitz, one of twenty-one similar concentrated attacks that the Germans quickly attributed to the Polish. Once inside the radio station, a short broadcast of an anti-German message in Polish was made (although sources vary on the content of the message).
