ヴォルフスシャンツェ
The attempted assassination of Hitler at the Wolf's Lair was part of Operation Valkyrie, a covert plan to take control and suppress any revolt in the German Reich following Hitler's death. News arrived from Wolf's Lair that Hitler was still alive, and troops loyal to the Nazi regime quickly re-established control of key government buildings. Von Stauffenberg, his adjutant Werner von Haeften, and several co-conspirators were arrested and shot the same evening outside the Bendlerblock in Berlin.
