on 23 August. 1 September 1942 was Marseille's most successful day, claiming to destroy 17 Allied aircraft (nos. 105–121), and September would see him claim 54 victories, his most productive month. The 17 aircraft claimed included eight in 10 minutes; as a result of this feat, he was presented with a Volkswagen Kübelwagen by a Regia Aeronautica squadron, on which his Italian comrades had painted "Otto" (Italian language: Otto = eight). This was the most aircraft from Western Allied air forces shot down by a single pilot in one day. Only three pilots would ever match this score, while only one pilot would ever surpass it; Emil Lang, on 4 November 1943, scored 18 fighters of the Soviet Air Force on the Eastern Front. The post-war analysis shows that the actual results of the day were probably eight to nine destroyed by Marseille with three or four more damaged. On 3 September 1942 Marseille claimed six victories (nos. 127–132) but was hit by fire from the British-Canadian ace James Francis Edwards. Der Adler, a biweekly propaganda magazine published by the Luftwaffe, also reported his actions in volume 14 of 1942. Marseille was made famous through propaganda that treated fighter pilots as superstars and continued to do so after his death. He regularly signed postcards with his image. Aside from Der Adler, his exploits were published in Berliner Illustrirte Zeitung and Die Wehrmacht. Three days later Edwards likely killed Günter Steinhausen, a friend of Marseille. The next day, 7 September 1942, another close friend, Hans-Arnold Stahlschmidt, was posted missing in action. These personal losses weighed heavily on Marseille's mind along with his family tragedy. It was noted he barely spoke and became more morose in the last weeks of his life. The strain of combat also induced consistent sleepwalking at night and other symptoms that could be construed as posttraumatic stress disorder. Marseille never remembered these events. Marseille flew Bf 109 E-7 aircraft and Bf 109 F-4/Z aircraft. Marseille continued scoring multiple victories throughout September, including seven on 15 September (nos. 145–151). Between 16 and 25 September, Marseille failed to increase his score due to a fractured arm, sustained in a forced landing soon after the 15 September mission. As a result, he had been forbidden to fly by Eduard Neumann. But the same day, Marseille borrowed the Macchi C.202 '96–10' of the Italian ace Tenente Emanuele Annoni, from 96a Squadriglia,
