World War II in Europe had begun on Friday 1 September 1939 when German forces
invaded Poland. On 6 December 1939, Meimberg was posted to
Jagdgeschwader 2 "Richthofen" (JG 2—2nd Fighter Wing), named after World War I fighter ace
Manfred von Richthofen, which at the time was based at
Zerbst. At Zerbst,
Hauptmann Wolfgang Schellmann was tasked with the creation of the new II.
Gruppe (2nd group) of JG 2 on 15 December. The
Gruppe was staffed by personnel from I.
Gruppe of JG 2, I.
Gruppe of
Jagdgeschwader 3 (JG 3—3rd Fighter Wing), and newly trained fighter pilots from the fighter pilot schools. There, Meimberg was assigned to 4.
Staffel (4th squadron), headed by
Oberleutnant Hans Hahn. Meimberg was appointed
Staffelkapitän (squadron leader) of 3.
Staffel of JG 2 on 15 April 1941. He replaced
Oberleutnant Hermann Hollweg who was transferred. On 4 August 1942, Meimberg succeeded
Oberleutnant Rudolf Pflanz as
Staffelkapitän of 11.
Staffel of JG 2. Pflanz had been
killed in action on 31 July.
Mediterranean Theater On 4 November 1942, Meimberg and his 11.
Staffel received orders to immediately transfer to Sicily. That same day, 30 men and their equipment were flown in three
Junkers Ju 52 transport aircraft from the airfield Poix-Nord at
Poix-de-Picardie in France to
Coleman Army Airfield, refueling at
Reims. On 8 November, the
Staffel arrived in
Trapani, located in the northwest of Sicily, and then moved to
Comiso which is in southeastern part of Sicily. On 15 November, Meimberg received orders to move his
Staffel to
Tunisia in North Africa where they were based at the
Bizerte Airfield where they fought in the
Tunisian campaign. That day, the
Oberbefehlshaber Süd (Commander in Chief South),
Generalfeldmarschall Albert Kesselring, ordered 11.
Staffel disbanded, and its pilots and equipment assigned to II.
Gruppe of
Jagdgeschwader 53 (JG 53—53rd Fighter Wing). Due to Meimberg's intervention,
Oberstleutnant Günther Freiherr von Maltzahn, the
Geschwaderkommodore (wing commander) of JG 53, decided to retain 11.
Staffel as its own entity and subordinated the
Staffel to the
Geschwaderstab (headquarters unit) of JG 53 while for the higher Luftwaffe authorities the
Staffel was merged with 6.
Staffel of JG 53. On 17 December, Meimberg was given home-leave. During this vacation on 29 December, he married his fiancée Margret in Münster. The two had known each other since school. The marriage produced a son, Gerrit, born 15 February 1946, and another son, Helmut, born 11 August 1948, and their daughter Dorothee, born 19 October 1950. Following a brief honeymoon which the couple spent in
Würzburg, Meimberg returned to his unit on 20 January 1943, which at the time was based at
El Aouina, a municipality of
Tunis, Tunisia. Flying the
Messerschmitt Bf 109 G-4 trop (
Werknummer 16025—factory number) on 1 February 1943, Meimberg was wounded in aerial combat with
Boeing B-17 Flying Fortress bombers near
Pont du Fahs. The severe burns he sustained necessitated a lengthy stay in a hospital in
Munich. During his convalescence, Meimberg was promoted to
Hauptmann (captain) on 1 March, and awarded the
Wound Badge in Silver () in May. He returned to JG 53 on 19 August and was assigned to the
Geschwaderstab. By this date, 11.
Staffel of JG 2 had officially been disbanded and its pilots distributed to various
Staffeln of JG 53. The
Geschwaderstab was based at the
Hermitage of Camaldoli in
Naples. Due to the
Allied invasion of Italy, the location was abandoned on 9 September, moving to
Littoria Airfield until September 16, and then to
Centocelle Airfield near
Rome. Shortly before Christmas, Meimberg left JG 53 again as his injuries sustained to his hands on 1 February required further treatment and
skin grafting.
Defense of the Reich On 24 April 1944, Meimberg was appointed
Gruppenkommandeur of II.
Gruppe of JG 53. He succeeded
Hauptmann Gerhard Michalski who was transferred. On 24 October, Meimberg was awarded the
Knight's Cross of the Iron Cross () for 45 aerial victories. The presentation was made by
Oberst Karl Hentschel, commander of the 7.
Jagddivision (7th Fighter Division), at the
Malmsheim Airfield. Meimberg flew his last combat mission on 17 April 1945,
strafing US vehicles travelling on the
Autobahn near
Nürnberg. During this attack, his Bf 109 G-14/AS was hit in the engine by
anti-aircraft artillery. He was forced to bail out and landed safely in a field where he was picked up by a
SS-unit and taken back to his unit at
Rißtissen, located approximately southwest of
Ulm. On 22 April, Meimberg moved II.
Gruppe to an makeshift airfield near
Waal. Aerial operation had practically came to a stop as US forces had started crossing the
Danube the following day. Meimberg dismissed his soldiers and disbanded II.
Gruppe in the early morning on 27 April. ==Later life==
