Kampfgeschwader 4

''Kampfgeschwader'' 4 "General Wever" (KG 4) (Battle Wing 4) was a Luftwaffe bomber wing during World War II. The unit was formed in May 1939. The unit operated the Dornier Do 17, Junkers Ju 88 and Heinkel He 111 medium bombers, with later service on the Heinkel He 177 heavy bomber. The wing was named after General Walther Wever, the prime pre-war proponent for a strategic bombing capability for the Luftwaffe, who was killed in an aircraft accident in 1936.

History

''Stab''/KG 4 and I./KG 4 were formed on 1 May 1939 at Erfurt and was initially equipped with the He 111 Ps, borrowed from KG 253. The unit spent most of the summer training and recruiting personnel from the flight schools.

On 25 August the unit was transferred to Langenau under the Command of ''Luftflotte 4''.
It began the Polish Campaign attacking airfields and railway yards. ''Stab''/KG 4 was withdrawn on 20 September.
I./KG 4 attacked airfields at Dęblin and Krakow on 1 September and again on 2 September. From 3–6 September rail targets in Eastern Poland were attacked, and between 6–9 September bridges along the Vistula River and in Warsaw itself were bombed. From 6–14 September rail targets were again bombed. Troop concentrations became the main targets after this until the Polish surrender.
II./KG 4 also supported 10.''Armee'' over Kutno in mid September. After the campaign the unit began training in night flying and began to lay mines of the Norwegian coast in January 1940, in preparation for the Norwegian Campaign.
III./KG 4 participated in the Battle of the Bzura in which the Polish Army was surrounded and destroyed (largely by the ''Luftwaffe'').

Invasions of Denmark and Norway

In December 1939 III./KG4 transferred from Nordhausen to Vechta and commenced intensive training for night flying and minelaying operations, while conversion to the Junkers Ju 88 began in February-1940. On 1 February 1940 transferred to Quakenbrück in northern Germany. II./KG 4 were part of the bomber fleet that flew a "demonstration of strength" raid over Copenhagen on 9 April 1940. The unit attacked rail and airfield targets as well as anti-shipping strikes. A ''Staffel'' of Ju 88s of III./KG 4 attacked the airfield at Sola Air Station near Stavanger and sank the Norwegian destroyer ''Æger'' near Stavanger on 9 April.

Battle of the Netherlands and France

KG 4 commanded by "Geschwaderkomodore" "Oberst" Martin Fiebig helped neutralise Dutch air power on 10 May 1940 by striking at airfields and Dutch AA positions and airlifted supplies to the ''Fallschirmjäger'' units in the Netherlands. Three Heinkels 111 leading an attack on Waalhaven-airport, Rotterdam in the early morning of May 10 belonged to "Stabsstaffel". Ca. 30 planes followed. After the German bombing, First Lieutenant P.Noomen of Dutch 3 JaVa took off as patrol commander in a Fokker G.I.A-311 armed with eight machineguns and managed to hit the leading, middle Heinkel 111 (5J+DA) flown by pilot Hlubeck and commanded by "Oberst" Fiebig. It tried to escape by flying lowly back northward over the Northsea. It was subsequently downed by famous Dutch pilot G. Sonderman flying his Fokker 311 after he had successfully hit and downed both a German Junkers Ju 52 and a Messerschmitt. After the quick surrender of the Dutch KG 4 shifted its attention to Belgium. During the Battle of France KG 4 helped paralyse Allied rail networks across Belgium. also flew sorties over Dunkirk'' striking at airfields in and around Paris to destroy the remaining units of the Armée de l’Air. By 5 June French aerial resistance, while never effective and sporadic, ceased.

Before the French campaign was over, KG 4 struck at British ports and targets in Wales. on the night of 18/19 June KG 4 lost six Do 17s and He 111s, including ''Major'' Dietrich Von Massenbach, ''Kommandeur'' of II./KG 4, who was shot down over Norfolk by a Blenheim of 23 squadron flown by Flt Lt Duke-Woolley, He 111 5J+DM crash landed on the beach at Cley Next the Sea, where the entire crew were taken prisoner.

On 4 September II./KG 4 had 37 He 111s (30 serviceable). II./KG suffered light losses during this period, due to flying at night.
III./KG 4 had 25 Ju 88s on strength with 23 serviceable on 13 August 1940. By 4 September that had shrunk to 14 combat ready out of a total of 30 machines, due to losses.

During the Yugoslavian invasion, II./KG 4 participated in the bombing of Belgrade, with 25 He 111s (out of 28 serviceable) on 6 April 1941. II. ''Gruppe'' mined the waters off Alexandria and the Suez Canal. A detachment, 4.''staffel'', under the command of ''Hauptmann'' Schwanhauser, was sent to Iraq to support the uprising against the British during the Anglo-Iraqi War.

On 6 April 1941 III./KG4 bombed and mined Piraeus harbour, sinking several vessels and damaging the harbour installations. On 11 April elements of III./KG 4 attempted to lay mines at the entrance to Volos harbour. High-scoring RAF ace S/L “Pat” Pattle of No. 33 Squadron attacked the units involved and shot down a Ju 88 of III./KG 30 and a Ju 88A-5 ‘4D+FS’ of 8./KG 4.

Eastern Front

''Stab''. supported Army Group North during its advance to Leningrad. In January 1942 the unit relocated to Pskov. On 22 January 1942 it helped drop supplies to the Kholm Pocket, and in February–March it flew supply missions over the Demyansk Pocket suffering heavy losses. I. ''Gruppe'' was committed to supporting Army Group Centre II. ''Grupe'' began its aerial offensive over the city on 1 October. During the winter the unit also flew bombing raids over Moscow. II. ''Gruppe'' supported Army Group South and its offensive into the Ukraine. II. ''Gruppe'' flew its 10,000th sortie on 9 March 1943. A notable success occurred on 14 March when the ''Gruppe'' attacked a Soviet airfield around Kursk destroying 40 enemy machines and damaging 23 others. II ''Gruppe'' also flew strategic bombing missions, against the Tank factory at Gorky and missions against the rubber factories near Yaroslavl. III. ''Gruppe'' was committed to the Southern wing of the front and managed to hit targets over Astrakhan.
In October 1943 the unit was partially equipped with the Heinkel He 177A to perform heavy bomber missions.
