Operation Valkyrie
Opposition to Hitler nevertheless continued, including among the General Staff officers of the "Ersatzheer" ("Replacement Army"), which had charge of all new troops being organized in Germany for the field army. They set up "Operation Valkyrie", in which "Ersatzheer" detachments would take control of Germany. On 20 July 1944, the conspirators tried to kill Hitler, thought they had succeeded, and initiated "Valkyrie". But most line officers and the bulk of the General Staff refused to obey the "Valkyrie" plotters; when Hitler was known to be alive, the coup collapsed entirely.
