territory, capturing Kraków, Warsaw and Poznań. In consequence, Romm as an experienced unit leader was transferred back to IV. Sturmgruppe of JG 3 again taking command of 15. Sturmstaffel. He took command from Leutnant Karl-Dieter Hecker who had taken command of the Sturmstaffel after Weydenhammer had been transferred in December 1944. On 21 January 1945, IV. Sturmgruppe was ordered to relocate from Gütersloh Airfield to Märkisch Friedland, present-day Mirosławiec, located approximately east of Stargard. With this transfer, the Sturmgruppe came under the control of the 1. Flieger-Division (1st Air Division), commanded by Generalmajor Robert Fuchs, and subordinated to II. Fliegerkorps (2nd Air Corps), headed by General der Flieger Martin Fiebig. On 27 January, Märkisch Friedland had to be abandoned and the Sturmgruppe retreated to an airfield southwest of Stargard. Over the next weeks, the Sturmgruppe predominantly flew fighter-bomber missions in support of German ground forces retreating towards the Oder. Reichsmarschall Hermann Göring, the commander-in-chief of the Luftwaffe, visited the Sturmgruppe on 13 February at Prenzlau. Göring was furious when he learned that the pilots were unable to fly missions due to lack of fuel. On 17 February 1945, Romm was appointed Gruppenkommandeur (group commander) of IV. Sturmgruppe of JG 3. He succeeded Major Erwin Bacsila who was transferred to Jagdgeschwader 400 (JG 400—400th Fighter Wing). Command of 15. Sturmstaffel was then passed to Leutnant Karl-Dieter Hecker. The next day, the Sturmgruppe flew ground support missions southeast of Stargard. During this mission, Luftwaffe pilots claimed four aerial victories, including an Il-2 ground-attack aircraft by Romm. Summary of career Aerial victory claims According to US historian David T. Zabecki, Romm was credited with 92 aerial victories. Spick also lists Romm with 92 aerial victories, of which 82 were claimed over the Eastern Front and further 10 over the Western Front, claimed in 229 combat missions. Mathews and Foreman, authors of Luftwaffe Aces — Biographies and Victory Claims, researched the German Federal Archives and found records for 88 aerial victory claims. This figure includes 78 aerial victories on the Eastern Front and 10 over the Western Allies, including eight four-engined heavy bombers, claimed in 283 combat missions. Victory claims were logged to a map-reference (PQ = Planquadrat), for example "PQ 07651". The Luftwaffe grid map () covered all of Europe, western Russia and North Africa and was composed of rectangles measuring 15 minutes of latitude by 30 minutes of longitude, an area of
