Loringhoven provided the detonator charge and explosives for the assassination attempt against Hitler on 20 July 1944. He was able to obtain captured British explosives from German intelligence ("Abwehr") sources. British explosives were used in order to make it harder to detect who had supplied them, and also to imply that the British were involved in the plot, thereby diverting attention from the actual conspirators. Nonetheless, Ernst Kaltenbrunner, Chief of the Reich Security Main Office ("Reichssicherheitshauptamt"; RSHA), discovered the actions of Loringhoven. On 26 July 1944, immediately before he was to be arrested by the Gestapo and fully aware of the interrogation techniques utilized by them, Loringhoven committed suicide at Mauerwald in East Prussia.
