Here it goes:
Wilhelm Steinmann was born on 15 January 1912 at Nürnberg. He joined the Luftwaffe in 1936 and trained as a bomber pilot. Steinmann served with 3./KG 53 from 1939 to 1941. He later served as Technischer Offizier with II./Fliegerkorps. He then underwent conversion training to become a fighter pilot. On 6 October 1942, Steinmann was posted to the Gruppenstab of I./JG 27 based on the
Channel front. He was serving with 3./JG 27 when he recorded his first victory on 18 May 1943, a RAF Typhoon fighter-bomber shot down over the Channel. On 1 June,
Steinmann claimed a RAF Spitfire shot down. However, he had made a mistake in identification and had shot down a Bf 109 G-6 flown by the Gruppenkommandeur of I./JG 27, Hauptmann Erich Hohagen (56 victories, RK). Hohagen was forced to bail out of his Bf 109 G-6 (W.Nr. 16 391) but had been wounded in the incident.
