Several more attempts followed before the failed 20 July 1944 plot, which was at least partly motivated by the increasing prospect of a German defeat in the war.[442][443] The plot, part of Operation Valkyrie, involved Claus von Stauffenberg planting a bomb in the conference room at Wolf's Lair at Rastenburg. Hitler, who narrowly survived, later ordered savage reprisals resulting in the execution of more than 4,900 people.[444]
