As the war progressed, Hitler's attention became focused on foreign affairs and the conduct of the war. Hess, whose duties did not require him to be directly engaged in the war, became increasingly sidelined from the affairs of the nation and from Hitler's attention. He was excluded from most important decisions, and many in Hitler's inner circle thought him to be mad due to his eccentricities. Bormann had successfully supplanted Hess in many of his duties and had taken Hess' position at Hitler's side. Hess was concerned that Germany would face a war on two fronts as plans progressed for
Operation Barbarossa, the invasion of the
Soviet Union scheduled to take place in 1941. Hess decided to attempt to bring Britain to the negotiating table by travelling there himself to seek meetings with the British government. On 31 August 1940, Hess met with Karl Haushofer, who told Hess that he believed that
King George VI was opposed to Churchill and would dismiss him and send him to Canada at the first opportunity. Haushofer spoke of his belief that it was possible to make contact with the king via either General
Ian Hamilton or
the Duke of Hamilton. Hess decided they should contact his fellow aviator the Duke of Hamilton. The two men were not acquainted with each other: Hamilton and Hess were both present at a banquet at the
1936 Summer Olympics, but they sat at different tables and never spoke. Hess chose Hamilton in the mistaken belief that he was one of the leaders of a party opposed to war with Germany, and because Hamilton was a friend of Haushofer. On Hess's instructions, Haushofer wrote to Hamilton in September 1940, but the letter was intercepted by
MI5 and Hamilton did not see it until March 1941. A letter Hess wrote to his wife dated 4 November 1940 shows that in spite of not receiving a reply from Hamilton, he intended to proceed with his plan. Hess began training on the
Messerschmitt Bf 110, a two-seater twin-engine aircraft, in October 1940 under instructor
Wilhelm Stör, the chief test pilot at Messerschmitt. He continued to practise, as well as log his many cross-country flights, and found a specific aircraft which handled well—a Bf 110E-1/N—which was from then on held in reserve for his personal use. He asked for a radio compass, modifications to the oxygen delivery system, and large long-range fuel tanks to be installed on this plane, and these requests were granted by March 1941.
Flight to Scotland After a final check of the weather reports for Germany and the
North Sea, Hess took off at 17:45 on 10May 1941 from the airfield at
Augsburg-Haunstetten in his specially prepared aircraft. It was the last of several attempts to depart on his mission; previous efforts had to be called off due to mechanical problems or poor weather. Wearing a leather flying suit bearing the rank of captain, he brought along a supply of money and toiletries, a
torch, a camera, maps and charts, and a collection of 28 different medicines, as well as
dextrose tablets to help ward off fatigue and an assortment of
homoeopathic remedies. Setting a course towards
Bonn, Hess used landmarks on the ground to orientate himself and make minor course corrections. When he reached the coast near the
Frisian Islands, Hess turned and flew in an easterly direction for twenty minutes to stay out of range of British radar. He then took a heading of 335degrees for the trip across the North Sea, initially at low altitude but travelling for most of the journey at . At 20:58, he changed his heading to 245degrees, intending to approach the coast of
North East England near the village of
Bamburgh, Northumberland. As it was not yet sunset when he first approached the coast, Hess backtracked, zigzagging back and forth for 40minutes until it grew dark. Around this time, his auxiliary fuel tanks were exhausted so he released them into the sea. Also around this time, at 22:08, the British
Chain Home station at Ottercops Moss near
Newcastle upon Tyne detected Hess' presence and informed the
Filter Room at
Bentley Priory. He was quickly detected by several other stations, and the aircraft was designated as "Raid 42". at the site of the crash Two
Spitfires of
No. 72 Squadron RAF,
No. 13 Group RAF that were already in the air were sent to attempt an interception, but failed to find the intruder. A third Spitfire sent from
Acklington at 22:20 also failed to spot the aircraft; by then, it was dark and Hess had dropped to an extremely low altitude, so low that the volunteer on duty at the
Royal Observer Corps (ROC) station at
Chatton was able to correctly identify it as a Bf 110, and reported its altitude as . Tracked by additional ROC posts, Hess continued his flight into Scotland at high speed and low altitude, but was unable to spot his destination,
Dungavel House, so he headed for the west coast to orientate himself and then turned back inland. At 22:35, a
Boulton Paul Defiant sent from
No. 141 Squadron RAF based at
Ayr began pursuit. Hess was nearly out of fuel, so he climbed to and parachuted out of the plane at 23:06. He injured his foot, either while exiting the aircraft or when he hit the ground. The aircraft crashed at 23:09, about west of Dungavel House, the Duke of Hamilton's home. Hess would have been closer to his destination had he not had trouble exiting the aircraft. Hess's biographers Roger Manvell and Heinrich Fraenkel considered the flight to have been "the proudest technical achievement of Hess's life." Before his departure from Germany, Hess had given his adjutant,
Karlheinz Pintsch, a letter addressed to Hitler that detailed his plans to initiate peace negotiations with the UK. Hess intended to approach the Duke of Hamilton at his home in Scotland, hoping that the duke might then be willing to advocate for and assist him in negotiating peace with Germany on terms that would be acceptable to Hitler. Pintsch delivered the letter to Hitler at the Berghof around noon on 11 May. After reading the letter, Hitler let loose a cry heard throughout the entire Berghof and sent for a number of his inner circle, concerned that a
putsch might be underway. 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 authorised. "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". Ever since, speculation has continued that Hess's mission had been sanctioned by Hitler. Hess's flight to Scotland has been the subject of several other
conspiracy theories, including one that he was duped by British Intelligence into undertaking his mission. After the war,
Albert Speer discussed the rationale for the flight with Hess, who told him that "the idea had been inspired in him in a dream by supernatural forces. We will guarantee England her empire; in return she will give us a free hand in Europe." While in Spandau prison, Hess told journalist
Desmond Zwar that Germany could not win a war on two fronts. "I knew that there was only one way out – and that was certainly not to fight against England. Even though I did not get permission from the Führer to fly, I knew that what I had to say would have had his approval. Hitler had great respect for the English people ..." Hess wrote that his flight to Scotland was intended to initiate "the fastest way to win the war."
Capture Shortly before midnight on 10 May 1941, Hess landed at Floors Farm, by
Waterfoot, south of Glasgow, where he was discovered still struggling with his parachute by local ploughman David McLean. Identifying himself as "
Hauptmann Alfred Horn", Hess said he had an important message for the Duke of Hamilton. McLean helped Hess to his nearby cottage and contacted the local
Home Guard unit, who escorted the captive to their headquarters in
Busby, East Renfrewshire. Hess was next taken to the police station at
Giffnock, arriving after midnight. He was searched and his possessions confiscated. Hess repeatedly requested to meet with the Duke of Hamilton during questioning undertaken with the aid of an interpreter by Major Graham Donald, the area commandant of the Royal Observer Corps. After the interview, he was taken under guard to
Maryhill Barracks in Glasgow, where his injuries were treated. By this time, some of his captors suspected his true identity, though Hess continued to insist his name was Horn. of Hess' Bf 110.
Imperial War Museum (2008) Hamilton had been on duty as
wing commander at
RAF Turnhouse near Edinburgh when Hess had arrived, and his station had been one of those that had tracked the progress of the flight. He arrived at Maryhill Barracks the next morning, and after examining Hess' effects, he met alone with the prisoner. Hess immediately admitted his true identity and outlined the reason for his flight. Hamilton told Hess that he hoped to continue the conversation with the aid of an interpreter; Hess could speak English well, but was having trouble understanding Hamilton. He told Hamilton that he was on a "mission of humanity" and that Hitler "wished to stop the fighting" with England. After the meeting, Hamilton examined the remains of the Messerschmitt in the company of an intelligence officer, then returned to Turnhouse, where he made arrangements through the
Foreign Office to meet Churchill, who was at
Ditchley Park in Oxfordshire for the weekend. They had some preliminary talks that night, and Hamilton accompanied Churchill back to London the next day, where they both met with members of the
War Cabinet. Churchill sent Hamilton with foreign affairs expert
Ivone Kirkpatrick, who had met Hess previously, to positively identify the prisoner, who had been moved to
Buchanan Castle overnight. Hess, who had prepared extensive notes to use during this meeting, spoke to them at length about Hitler's expansionary plans and the need for Britain to let the Nazis have free rein in Europe, in exchange for Britain being allowed to keep its overseas possessions. Kirkpatrick held two more meetings with Hess over the course of the next few days, while Hamilton returned to his duties. In addition to being disappointed at the apparent failure of his mission, Hess began claiming that his medical treatment was inadequate and that there was a plot afoot to poison him. Hess' flight, but not his destination or fate, was first announced by
Munich Radio in Germany on the evening of 12 May. The following day, Hitler sent Foreign Minister
Joachim von Ribbentrop to give the news in person to Mussolini, and the British press was permitted to release full information about events that same day. On 14 May, Ilse Hess finally learned that her husband had survived the trip when news of his fate was broadcast on German radio. Hitler worried that
Germany's allies,
Italy and
Japan, would perceive Hess' 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 Hitler's cabinet, 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. Goebbels commented in his diary that the German public was wondering how "such a fool" could be second to Hitler. Hitler stripped Hess of all of his party and state offices, and secretly ordered him shot on sight if he ever returned to Germany. Hitler abolished the post of Deputy Führer, assigning Hess' 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. Two sections of the fuselage of the aircraft were initially hidden by David McLean and later retrieved. One part was sold to the former assistant secretary of the Battle of Britain Association, who gave it to a war museum in the US; this part was later sold by
Bonhams at auction. Part of the fuel tank and a strut were offered for sale via Bonhams in 2014. Other wreckage was salvaged by 63 Maintenance Unit between 11 and 16 May 1941 and then taken to
Oxford to be stored. The aeroplane had been armed with four machine guns in the nose, but carried no ammunition. One of the engines is on display at the
RAF Museum while the
Imperial War Museum displays another engine and part of the fuselage. ==Trial and imprisonment==
