Staffel of Jagdgeschwader 51 "Mölders" (JG 51—51st Fighter Wing) had been staffed with a full complement of 16 pilots, including Romm. The Staffel was ordered to relocate to the Western Front where it was attached to IV.

Sturmgruppe was based at Salzwedel and commanded by Hauptmann Wilhelm Moritz. Romm was appointed Staffelkapitän (squadron leader) of 12. Sturmstaffel of JG 3 on 7 July 1944. He replaced Oberleutnant Hans Rachner who had been killed in action that day. On 7 July, a force of 1,129 B-17 Flying Fortress and B-24 Liberator bombers of the United States Army Air Forces (USAAF) Eighth Air Force had set out from England to bomb aircraft factories in the Leipzig area and the synthetic oil plants at Boehlen, Leuna-Merseburg and Lützkendorf.

Sturmgruppe of JG 3, led by Moritz, escorted by two Gruppen of Bf 109s from Jagdgeschwader 300 (JG 300—300th Fighter Wing) led by Major Walther Dahl.
