his inner circle, concerned that a putsch might be underway. Hitler worried that his allies, Italy and Japan, would perceive Hess's act as an attempt by Hitler to secretly open peace negotiations with the British. Hitler contacted Mussolini specifically to reassure him otherwise. For this reason, Hitler ordered that the German press should characterise Hess as a madman who made the decision to fly to Scotland entirely on his own, without Hitler's knowledge or authority. Subsequent German newspaper reports described Hess as "deluded, deranged," indicating that his mental health had been affected by injuries sustained during World War I. Some members of the government, including Göring and Propaganda Minister Joseph Goebbels, believed this only made matters worse, because if Hess truly were mentally ill, he should not have held an important government position. Hitler stripped Hess of all of his party and state offices, and secretly ordered him shot on sight if he ever returned to Germany. He abolished the post of Deputy Führer, assigning Hess's former duties to Bormann, with the title of Head of the Party Chancellery. Bormann used the opportunity afforded by Hess's departure to secure significant power for himself. Meanwhile, Hitler initiated Aktion Hess, a flurry of hundreds of arrests of astrologers, faith healers and occultists that took place around 9 June. The campaign was part of a propaganda effort by Goebbels and others to denigrate Hess and to make scapegoats of occult practitioners. US journalist Hubert Renfro Knickerbocker, who had met both Hitler and Hess, speculated that Hitler had sent Hess to deliver a message informing Winston Churchill of the forthcoming invasion of the Soviet Union, and offering a negotiated peace or even an anti-Bolshevik partnership. Soviet leader Joseph Stalin believed that Hess's flight had been engineered by the British. Stalin persisted in this belief as late as 1944, when he mentioned the matter to Churchill, who insisted that they had no advance knowledge of the flight. While some sources reported that Hess had been on an official mission, Churchill later stated in his book The Grand Alliance that in his view, the mission had not been authorized. "He came to us of his own free will, and, though without authority, had something of the quality of an envoy", said Churchill, and referred to Hess's plan as one of "lunatic benevolence". After the war, Albert Speer discussed the rationale for the flight with Hess, who
