Leopold Münster

Münster claimed his first aerial victory over the USAAF on 13 November. That day, the Eighth Air Force targeted Bremen and Münster was credited with shooting down a Boeing B-17 Flying Fortress bomber. On 24 April 1944, Münster was temporarily put in command of II. Gruppe after its former commander Hauptmann Hermann Freiherr von Kap-herr was killed in action. Münster surrendered command to Hauptmann Gustav Frielinghaus at Gardelegen Airfield on 1 May. Since Frielinghaus was still convalescing from injuries sustained in December 1943, Frielinghaus led the Gruppe from the ground while Münster continued to lead in the air.

On 8 May, Münster was killed in a mid-air collision with a Consolidated B-24 Liberator bomber, possibly from the 445th Bombardment Group. His Messerschmitt Bf 109 G-6/U4 (Werknummer 441142—factory number) crashed near Wöllersheim, present-day part of Lamspringe, approximately 18 kilometers (11 miles) south-southeast of Hildesheim. Münster was replaced by Leutnant Hans Grünberg as commander of 5. Staffel. Münster was posthumously awarded the 471st Knight's Cross of the Iron Cross with Oak Leaves (Ritterkreuz des Eisernen Kreuzes mit Eichenlaub) on 12 May 1944. On 20 May, he was given a military funeral in his hometown Pohorsch.

The increasing daytime attacks of the United States Army Air Forces (USAAF) Eighth Air Force against targets in western Europe forced the Luftwaffe to transfer more and more fighter units from the Eastern Front back to Germany in Defense of the Reich. On 3 August 1943, II. Gruppe's air elements arrived at Uetersen Airfield in northern Germany. Münster was appointed Staffelkapitän (squadron leader) of 5. Staffel of JG 3 on 20 October 1943. He succeeded Hauptmann Heinrich Sannemann who was transferred.

At Wiesbaden-Erbenheim airfield, II. Gruppe was equipped with Messerschmitt Bf 109 F-4 trop as the unit was to be deployed in the Mediterranean Theatre. After almost two months of rest, II. Gruppe was ordered to transfer to Sicily in early January 1942. Münster claimed one aerial victory in this theatre of operations. On 22 February, II. Gruppe was ordered to an airfield at Santo Pietro, approximately 15 kilometers (9.3 miles) northwest of Comiso, Sicily. That day, Münster claimed a Hawker Hurricane shot down over Malta. II. Gruppe flew its last combat mission over Malta on 25 April 1942. On 27 April, II. Gruppe arrived at Plzeň where it was placed under the command of Hauptmann (Captain) Kurt Brändle.

On 21 July, II. Gruppe moved to an airfield at Novy Cholan located south of Tatsinskaya. In the following days, the Gruppe fought in the Battle of Kalach, supporting the German crossing of the Don. On 24 July, Münster became an "ace-in-a-day" when he shot down five Il-2 ground-attack aircraft and a Hurricane fighter, taking his total to 30 aerial victories claimed. From 21 November 1942 to March 1943, Münster was first hospitalized in Troppau, present-day Opava, where he received surgery and then spent some time convalescing. During this period, he was awarded the Knight's Cross of the Iron Cross (Ritterkreuz des Eisernen Kreuzes) on 21 December 1942 and promoted to Leutnant (second lieutenant). At the time, he had flown 322 combat missions and had claimed 51 aerial victories.

Born in Pohorsch, Münster grew up in the First Czechoslovak Republic. Following the German occupation of Czechoslovakia, he joined the Luftwaffe in January 1939. Following flight training, Münster was posted to Jagdgeschwader 3 (JG 3—3rd Fighter Wing) in March 1941. Flying with this wing, he claimed his first aerial victory on 6 July 1941 on the Eastern Front during Operation Barbarossa. Following his 51st aerial victory, Münster was awarded the Knight's Cross of the Iron Cross on 21 December 1942. In October 1943, he and his unit were transferred to the Western Front fighting in Defense of the Reich. He was then appointed Staffelkapitän (squadron leader) of the 5. Staffel (5th squadron) of JG 3. Münster was killed in a mid-air collision with a Consolidated B-24 Liberator bomber on 8 May 1944. Posthumously, he was awarded the Knight's Cross of the Iron Cross with Oak Leaves on 12 May 1944.

In preparation for Operation Barbarossa, the German invasion of the Soviet Union, II. Gruppe headed east on 18 June. Following a stopover at Kraków, the unit was moved to Hostynne. At the start of the campaign, JG 3 under the command of Major (Major) Günther Lützow was subordinated to the V. Fliegerkorps (5th Air Corps), under the command of General der Flieger (General of the Aviators) Robert Ritter von Greim, itself part of Luftflotte 4 (4th Air Fleet), under the command of Generaloberst (Colonel General) Alexander Löhr. These air elements supported Generalfeldmarschall (Field Marshal) Gerd von Rundstedt's Army Group South, with the objective of capturing Ukraine and its capital Kiev. At 17:00 on 21 June 1941, the 5th Air Corps, based at Lipsko, briefed the various unit commanders of the upcoming attack. That evening, Gruppenkommandeur (group commander) of II. Gruppe Keller informed his subordinates of the attack.

The invasion of the Soviet Union began on 22 June 1941. II. Gruppe flew its first missions on the Eastern Front shortly before 04:00, flying low attacks against Soviet airfields in the vicinity of Lvov in Ukraine. At 06:30 the Gruppe fought its first aerial battles. In the beginning of July 1941, the front in the vicinity of the northern sector of Army Group South became increasingly fluid. This necessitated the relocation of II. Gruppe to Volodymyr-Volynskyi. The rapid advance of German ground forces required II. Gruppe to move to Lutsk on 5 July and then to Dubno that evening. The following day, II. Gruppe flew combat air patrols over Berdychiv and Zhytomyr. On one of these missions, Münster claimed his first aerial victory over a ZKB-19, referring to an Ilyushin DB-3 bomber. On 9 July, he was credited with the destruction of two further DB-3 bombers. Münster received the Iron Cross 2nd Class (Eisernes Kreuz 2. Klasse) on 24 July 1941 and the Iron Cross 1st Class (Eisernes Kreuz 1. Klasse) on 7 September 1941.

Following his ninth aerial victory claimed and 86 combat missions flown, Münster was transferred to the Stab (headquarters unit) of II. Gruppe. There, he increased his total of aerial victories claimed to twelve. Additionally he was credited with five ground victories and the destruction of a locomotive, increasing his number of combat missions flown to 124. On 31 October 1941, II. Gruppe flew its last combat mission over the northern Crimean combat zone and was ordered to retreat to Germany for a period of rest and refurbishment. On 1 December 1941, JG 3 was given the honorary name "Udet" following the suicide of World War I fighter pilot and Luftwaffe Generalleutnant Ernst Udet. Münster was awarded the Front Flying Clasp of the Luftwaffe in Gold (Frontflugspange in Gold) on 16 December 1941.

Following the German occupation of Czechoslovakia in October 1938, Münster volunteered for military service and joined the Luftwaffe on 7 January 1939. Following his recruit training with Fliegerausbildungsregiment 43 (43rd Flight Training Regiment) at Ingolstadt, he was posted to the airfield staff at Leipheim on 1 April. After he had passed his flight aptitude test, he was transferred to flight school at Crailsheim on 1 June. There, he was trained as a pilot which he completed in June 1940. Münster was promoted to Gefreiter (Lance Corporal) on 1 October 1940. In July 1940, Münster was transferred to the advanced Flugzeugführerschule C (FFS C—advanced flight school) at Burg bei Magdeburg where he received further theoretical training. On 1 October, he was promoted to Unteroffizier (sergeant) and transferred to the 3. Staffel (3rd squadron) of Jagdfliegerschule 3, the fighter pilot school at Fürth.

World War II in Europe had begun on Friday, 1 September 1939, when German forces invaded Poland. Münster completed his fighter pilot training in March 1941 and then flew some missions in Defense of the Reich from Fürth and Zerbst. On 18 March, he was posted to the 2. Staffel of Ergänzungsgruppe of Jagdgeschwader 3 (JG 3—3rd Fighter Wing). The Ergänzungsgruppe was a supplementary training group attached to JG 3 under the command of Major Alfred Müller with 2. (Schul—training) Staffel headed by Oberleutnant Erwin Neuerburg. On 1 June, Münster was transferred to the 4. Staffel of JG 3. This Staffel was commanded by Hauptmann Gordon Gollob and subordinated to II. Gruppe of JG 3 led by Hauptmann Lothar Keller.

Leopold Münster (13 December 1920 – 8 May 1944) was a German Luftwaffe military aviator and fighter ace during World War II. He is credited with 95 aerial victories achieved in over 500 combat missions. This figure includes 70 aerial victories on the Eastern Front, and further 25 victories over the Western Allies, including eight four-engined bombers.

His father was a construction foreman and farmer, his mother died when he was three years old. In 1926, Münster attended the Volksschule, a combined primary and lower secondary school, in Hochheim. In 1931, he transferred to the Bürgerschule, a school preparing pupils for a vocational education. He graduated in 1935 and then learned the trade of a house painter and decorator as well as sign painter. In parallel, he attended the vocational school in Mährisch-Ostrau, present-day Ostrava. As a child, he was a member of the sudetendeutsche Jugendbewegung (Sudeten German youth movement).
