Operation Valkyrie
Olbricht now put forward a new strategy for staging a coup against Hitler. The Replacement Army ("Ersatzheer") had an operational plan called Operation Valkyrie, which was to be used in the event that the disruption caused by the Allied bombing of German cities would cause a breakdown in law and order, or an uprising by the millions of forced labourers from occupied countries now being used in German factories. Olbricht suggested that this plan could be used to mobilise the Reserve Army for the purpose of the coup.
