The Ersatzheer contingency plans for Operation Valkyrie were deliberately misused as part of the unsuccessful 20 July plot, for the assassination of Adolf Hitler, arrest of SS troops, and the staging of a military coup d'etat. Its commander, Generaloberst Friedrich Fromm, had enough power to control the German state because his position controlled army procurement and production and command of all army troops inside Germany.[3] Fromm had refused to cooperate in an earlier coup, Operation Spark (1940), but the planners in 1944 still planned to use the Reserve Army.
