 This warning of an imminent German attack, like that from Richard Sorge and from other Soviet agents, was dismissed by Joseph Stalin.After the outbreak of the German-Soviet War on June 22, 1941, Radó's network continued to provide Soviet General Staff with very valuable intelligence on German forces.Some of it was supplied through Puetner by "Zalter", a press officer of the French embassy in Switzerland and by "Long", a French intelligence officer who fled to Switzerland after the capitulation of France.
