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.
Oster Conspiracy The Oster Conspiracy of 1938 was a proposed plan to overthrow German "Führer" Adolf Hitler and the Nazi regime if Germany went to war with Czechoslovakia over the Sudetenland. It was led by Generalmajor (major general) Hans Oster, deputy head of the "Abwehr" and other high-ranking conservatives within the Wehrmacht who opposed the regime for its behaviour that was threatening to bring Germany into a war that they believed it was not ready to fight. They planned to overthrow Hitler and the Nazi regime through a planned storming of the Reich Chancellery by forces loyal to the plot to take control of the government, who would either arrest or assassinate Hitler, and restore the exiled Wilhelm II as Emperor.
