On 10 May 1941, Hess made a solo flight to Scotland, where he hoped to arrange peace talks with the Duke of Hamilton, whom he believed to be a prominent opponent of the British government's war policy.
He served a life sentence in Spandau Prison; the Soviet Union blocked repeated attempts by family members and prominent politicians to procure his early release.
Hess, the eldest of three children, was born on 26 April 1894 in al-Ibrahimiyya, a suburb of Alexandria, Egypt (then under British occupation, though formally a part of the Ottoman Empire), into a wealthy German family.
[9][10] The family lived in a villa on the Egyptian coast near Alexandria, and visited Germany often from 1900, staying at their summer home in Reicholdsgrün (now part of Kirchenlamitz) in the Fichtel Mountains.
[13] Hess's youth growing up under the "Veiled Protectorate" of Sir Evelyn Baring made him unique among the Nazi leaders in that he grew up under British rule, which he saw in very positive terms.
He demonstrated aptitudes for science and mathematics, but his father wished him to join the family business, Hess & Co., so he sent him in 1911 to study at the École supérieure de commerce in Neuchâtel, Switzerland.
After two months out of action with a throat infection, Hess served in the Battle of Verdun in May, and was hit by shrapnel in the left hand and arm on 12 June 1916 during fighting near the village of Thiaumont.
[20] Hess joined the Thule Society, an antisemitic right-wing Völkisch group, and the Freikorps of Colonel Ritter von Epp,[21] one of many such volunteer paramilitary organisations active in Germany at the time.
They held a shared belief in the stab-in-the-back myth, the notion that Germany's loss in World War I was caused by a conspiracy of Jews and Bolsheviks rather than a military defeat.
When the German government failed to meet its reparations payments and French troops marched in to occupy the industrial areas along the Ruhr in January 1923, widespread civil unrest was the result.
[37] Hess was with Hitler on the night of 8 November 1923 when he and the SA stormed a public meeting organised by Bavaria's de facto ruler, Staatskommissar (state commissioner) Gustav von Kahr, in the Bürgerbräukeller, a large beer hall in Munich.
Brandishing a pistol, Hitler interrupted Kahr's speech and announced that the national revolution had begun, declaring the formation of a new government with World War I General Erich Ludendorff.
[63] Its most notable impact was in the Sudetenland, where in 1933 it promoted Konrad Henlein as the politician with the best hope of building a Nazi-friendly party that would win mass support without being banned by the Czechoslovak government.
"[69] In a speech in 1937, Hess blamed the Spanish Civil War on "international Jewry", called the Soviet Foreign Commissar Maxim Litvinov a "dirty Jew", and claimed that without Hitler or Mussolini, "Jewish Asiatic Bolshevism would dominate European culture".
In a speech given on 20 April 1940 to mark Hitler's 51st birthday, Hess accused "Jews and their fellow travellers" of Germany's capitulation in November 1918, which he called the most calamitous event in world history.
[69] Hess was obsessed with his health to the point of hypochondria, consulting many doctors and other practitioners for what he described to his captors in Britain as a long list of ailments involving the kidneys, colon, gall bladder, bowels and heart.
[76] 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.
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.
[86] 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.
Also around this time, at 22:08, the British Chain Home station at Ottercops Moss near Newcastle upon Tyne detected his presence and informed the Filter Room at Bentley Priory.
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 orient himself and then turned back inland.
"[105] 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.
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 Royal Observer Corps.
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.
On 13 May, 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.
[149] Visitors were allowed to come for half an hour per month, but Hess forbade his family to visit until December 1969, when he was a patient at the British Military Hospital in West Berlin for a perforated ulcer.
[160] Conditions were far more pleasant in the 1980s than in the early years; Hess was allowed to move more freely around the cell block, setting his own routine and choosing his own activities, which included television, films, reading, and gardening.
[161] In 1967, Wolf Rüdiger Hess began a campaign to win his father's release, garnering support from politicians such as Geoffrey Lawrence[a] in the UK and Willy Brandt in West Germany, but to no avail, in spite of the prisoner's advanced age and deteriorating health.
[169] In a letter dated 8 September 1979, Hess announced that he would refuse treatment unless released, saying he deserved freedom as an "unjustly convicted man" and that if he were to die, his death would be on the consciences of the leaders of the UK, France, the Soviet Union, and the United States.
[174] Hess was found dead on 17 August 1987, aged 93, in a summer house that had been set up in the prison garden as a reading room; he had hanged himself using an extension cable strung over a window latch.
