'Bürkl' was a Polish operation by the Armia Krajowa resistance army to kill Franz Bürkl, a Sicherheitspolizei officer (7 September 1943).
The undertaking was the second action and first success of 'Główki', which was a series of assassinations of notorious SS officers in Warsaw carried out by the Agat ('Anti-Gestapo') special group of the Kedyw (Kierownictwo Dywersji or Directorate for Subversion) between 1943 and 1944. The object was to kill Bürkl, who had been sentenced to death by the Polish Special Courts of the Polish government-in-exile for the murder of several dozen people. Bürkl was ambushed in daylight on Warsaw’s main Marszałkowska street by five Armia Krajowa fighters armed with Sten sub-machine guns and Filipinka hand grenades.
The assassins, led by 21-year-old Jerzy Zborowski, had been recruited for Agat from the Szare Szeregi (grey ranks) underground scouting organisation. Bürkl and seven other German policemen were killed in the 90-second action. While the operation resulted in no losses for the resistance, the Nazis killed 20 inmates of the Pawiak prison in a public reprisal execution.
