managed to fly the battered craft home and land safely, it was scrapped. Having escaped injury by the explosion, he was lightly wounded the next day by a ricocheting bullet. He was shot down on 22 September by American ace George Vaughn, but survived. On 29 September, his requested transfer came through, and he shifted to Royal Prussian Jagdstaffel 6. By this time, Noltenius had successfully shot down another four enemy airplanes and three more balloons, raising his score to 13, with one pending. He shot down another balloon, and a Sopwith Camel in his new squadron. Then a clash with Ulrich Neckel, his commanding officer, led to another move, this time to Royal Prussian Jagdstaffel 11. He scored three victories for his new squadron on 23 October. Three more single-handed victories, on 28 October, 3 and 4 November, closed out his list of victims—his 21st and last officially credited victory was over an Airco DH.4 bomber of the American 11th Aero Squadron. On 8 November, Noltenius received the Royal House Order of Hohenzollern. His twentieth victory qualified him for the Pour le Mérite, but the Armistice three days later put an end to those awards. He had flown 141 combat sorties by war's end. Postwar life After the Armistice ended the war, Germany was in chaos. Revolutionists from both extremes of the political spectrum fought for governance of their nation. Noltenius enrolled in the Freikorps for the German Revolution of 1918-1919, fighting against the communist Spartacus League revolutionists attempting to take over Germany. He then completed his medical studies. Once he qualified as a doctor, he moved his family to South America. He returned to Germany in 1933, and again took up flying. In 1936, Noltenius was one of the German flying veterans asked by Luftwaffe historians to contribute his extensive diaries to the government archives because the Jagdeschwader III war diary was incomplete. He obliged them. As a result, historians found that the wing's total air victories during its nine months of existence was found to amount to about 370 enemy aircraft destroyed. Just before 2 PM on 1 March 1936, Friedrich Noltenius took off from Johannisthal Air Field near Berlin. He crashed his Bücker Bü 131 biplane and died en route to hospital. His legacy In addition to German historians' use of his diaries in 1936, in later years The League for Aviation Historians would publish English
