What is a common name for the effort of Kurt von Plettenberg and other German officials attempting to assassinate Adolf Hitler which originally referenced only part of the plot?
Kurt von Plettenberg Kurt Freiherr von Plettenberg (31 January 1891 in Bückeburg – 10 March 1945 in Berlin) was a German forester, cavalry officer and a member of the German Resistance (Widerstand). He was involved in the preparations for the 20 July plot, an attempt to assassinate Adolf Hitler, Führer of the Third Reich. Plettenberg belonged to the circle of close friends which included Claus Schenk Graf von Stauffenberg, Johannes Popitz, Ludwig Beck, Ulrich von Hassell, Carl-Hans Graf von Hardenberg and Fabian von Schlabrendorff.
Schwarze Kapelle The Schwarze Kapelle (German for "Black Orchestra") was a term used by the Gestapo to refer to a group of conspirators within the German military who plotted to overthrow Adolf Hitler. It included many senior officers within the Wehrmacht. Unlike the "Rote Kapelle" (Red Orchestra), the name given by the Gestapo to the Soviet spy network within the Third Reich, the members of the "Black Orchestra" were of aristocratic background, felt contempt for the ideological fervor of the Nazi Party and were politically closer to the Western Allies.
