Soon after the war ended, Major Wilhelm Trapp was captured by the British authorities and placed at the Neuengamme Internment Camp. After questioning by the Polish Military Mission for the Investigations of War Crimes in October 1946,[51] he was extradited to Poland along with Drewes, Bumann and Kadler. Subsequently, Trapp was charged with war crimes by the Siedlce District Court, sentenced to death on 6 July 1948 and executed on 18 December 1948 along with Gustav Drewes.[2] However, with the onset of the Cold War, West Germany did not pursue any war criminals at all for the next twenty years.[52][53] In 1964 several men were arrested.
