a shell splinter to the left arm, which was dressed in the field, but the second was a bullet wound that entered the upper chest near the armpit and exited near his spinal column, leaving a pea-sized entry wound and a cherry stone-sized exit wound on his back. By 20 August, he was well enough to travel, so he was sent to hospital in Hungary and eventually back to Germany, where he recovered in hospital in Meissen. In October he received promotion to Leutnant der Reserve and was recommended for, but did not receive, the Iron Cross, first class. At his father's request, Hess was transferred to a hospital closer to home, arriving at Alexandersbad on 25 October. While still convalescing, Hess had requested that he be allowed to enroll to train as a pilot, so after Christmas leave with his family, he reported to Munich. He received basic flight training at Oberschleissheim and Lechfeld Air Base from March to June 1918, and advanced training at Valenciennes in France in October. On 14 October, he was assigned to Jagdstaffel 35b, a Bavarian fighter squadron equipped with Fokker D.VII biplanes. He saw no action with Jagdstaffel 35b, as the war ended on 11 November 1918, before he had the opportunity. Hess was discharged from the armed forces in December 1918. The family fortunes had taken a serious downturn, as their business interests in Egypt had been expropriated by the British. Hess joined the Thule Society, an antisemitic right-wing Völkisch group, and the Freikorps of Colonel Ritter von Epp, one of many such volunteer paramilitary organisations active in Germany at the time. Bavaria witnessed frequent and often bloody conflicts between right-wing groups, the Freikorps, and left-wing forces as they fought for control of the state during this period. Hess was a participant in street battles in early 1919 and led a group that distributed thousands of antisemitic pamphlets in Munich. He later said that Egypt made him a nationalist, the war made him a socialist, and Munich made him an antisemite. In 1919, Hess enrolled in the University of Munich, where he studied history and economics. His geopolitics professor was Karl Haushofer, a former general in the German Army who was a proponent of the concept of Lebensraum ("living space"), which Haushofer cited to justify the proposal that Germany should forcefully conquer additional territory in Eastern Europe. Hess later introduced this concept
