World War II in Europe began on Friday, 1 September 1939, when German forces
invaded Poland. Wilcke, who at the time was still a member of 3.
Staffel (3rd squadron) of JG 53, flew missions over Poland. He claimed his first aerial victory on 7 November 1939, over the
Western Front when he shot down an ''
Armée de l'Air'' (French Air Force)
Potez 630, a twin-engined fighter, near
Völklingen during the
Phoney War. For this achievement he was awarded the
Iron Cross 2nd Class () on 25 November 1939. From 2–16 January 1940, Wilcke and other pilots from III.
Gruppe went on a
ski vacation to the
Vorarlberg. On 11 March 1940, he shot down another Potez at an altitude of near the "
three-nations-corner" north of
Metz. He claimed his third victory at 2:55 p.m. on 25 March. 7.
Staffel engaged a flight of
Morane-Saulnier M.S.406 at . In the resulting aerial battle, Wilcke shot down one of the Moranes over
Diedenhofen.
Battle of France and Britain The
Battle of France, the German invasion of France and the
Low Countries, began on 10 May 1940. On 18 May 1940, he engaged in aerial combat with eight French
Curtiss P-36 Hawk fighter aircraft and was shot down west of
Rethel. His victor may have been
sous lieutenant Camille Plubeau. Wilcke
bailed out and was taken
prisoner of war. Following the
armistice with France, he and Mölders, who had also been a prisoner of war, returned to the unit on 30 June 1940. Wilcke was promoted to
Hauptmann the next day and again took command of 7.
Staffel. On 11 July 1940, he was awarded the Iron Cross 1st Class (). E-1 of JG 53, similar to those flown by Wilcke On 13 August 1940, during the
Battle of Britain, Wilcke replaced
Hauptmann Harro Harder as
Gruppenkommandeur of the III.
Gruppe. Harder had last been seen at 1:35 p.m. on 12 August and was reported as
missing in action following combat east of the
Isle of Wight. On the day of his appointment, Wilcke almost lost his life as well, when he was forced to bail out after engine failure over the
English Channel. He was rescued that night by a
Dornier Do 18 flying boat. III.
Gruppe flew a
bomber escort mission targeting
London on 30 August. Wilcke destroyed a
barrage balloon on the morning mission and claimed his fourth victory, a
Supermarine Spitfire near
Dover during his second mission of the day. On 1 September 1940, on another bomber escort mission that started at 11:20 a.m., Wilcke claimed his fifth victory, a
Hawker Hurricane, south of London. He claimed his sixth victory, probably a
Fairey Swordfish biplane, on 11 September over the Channel between Dover and
Calais. On 15 September 1940, also known as
Battle of Britain Day, III.
Gruppe engaged 20 to 30
Royal Air Force (RAF) fighters south of London. In the resulting combat, Wilcke claimed the destruction of his second Hurricane. Two days later, on a mission that began at 4:35 p.m., Wilcke achieved his ninth victory, another Hurricane. He claimed his tenth victory, again a Hurricane, on a mission targeting the London area that took off at 11:15 a.m. on 20 September. On the last day of September 1940, he claimed two more victories to bring his total to 12; the action took place during his second mission of the day, which began at 1:45 p.m., escorting
Dornier Do 17s to
London. In combat with RAF Spitfires, Wilcke claimed his 13th victory at 11:45 a.m. on 10 October 1940, his final of the Battle of Britain. In recognition of these achievements, he was awarded the
Honor Goblet of the Luftwaffe () on 1 April 1941.
Operation Barbarossa On 8 June 1941, the bulk of JG 53's air elements moved via
Jever, in northern Germany, to
Mannheim-Sandhofen. There the aircraft were given a maintenance overhaul prior to moving east. On 12 June, III.
Gruppe was ordered to transfer to a forward airfield at
Sobolewo. On 21 June, the
Geschwaderkommodore (wing commander) of JG 53 and its
Gruppenkommandeure were summoned to nearby
Suwałki, where
Generalfeldmarschall (field marshal)
Albert Kesselring gave the final instructions for the upcoming attack. Wilcke briefed his pilots that evening. On 22 June, the
Geschwader crossed into Soviet airspace to support
Operation Barbarossa, the invasion of the Soviet Union, which opened the
Eastern Front. III.
Gruppe took off on its first mission at 3:20 a.m. with the
Gruppenstab (headquarters unit) and 7.
Staffel targeting Soviet airfields at
Alytus and Oranji. Wilcke shot down three
Polikarpov I-15 biplane fighter aircraft. The second mission of the day by III.
Gruppe was a
Stuka escort mission to
Grodno at 6:00 a.m., during which Wilcke claimed another victory. He led another attack at 4:10 p.m.; while strafing airfields, he claimed his fifth aerial victory of the day, an "
ace-in-a-day" achievement, taking his total to 18. On 25 June 1941, JG 53 was relocated with III.
Gruppe arriving at
Vilnius at 8:30 am. The same day, Wilcke was slightly injured when he collided with another aircraft during
takeoff. He claimed his 19th victory on the evening of 30 June 1941, flying a
combat air patrol into the
Barysaw area. Wilcke was ordered to form "
Gefechtsverband Wilcke" ("Battle Group Wilcke") on 1 July 1941. He commanded his III.
Gruppe and II.
Gruppe of
Jagdgeschwader 52 (JG 52—52nd Fighter Wing) to counter-attack Soviet bombers. On 9 July, Wilcke destroyed a
Petlyakov Pe-2 ground-attack aircraft. He claimed a victory on 25 July during fighter escort missions in the
Vyazma area. On 29 July 1941, III.
Gruppe provided fighter cover for the German armored spearheads in the
Dukhovshchina area. During this mission, Wilcke claimed another victory. The next day, over the spearheads at
Yartsevo-
Bely, Wilcke shot down a
Polikarpov I-180 fighter. He was awarded the
Knight's Cross of the Iron Cross () on 6 August 1941 for 25 victories. Both Wilcke and
Leutnant Herbert Schramm were decorated by Kesselring on 9 August 1941. On 23 August 1941, the
9th Army began its assault on the Soviet forces in the
Velikiye Luki area. Wilcke claimed two aerial victories while supporting these operations. III.
Gruppe began returning to Germany in early October 1941. The air element left the Soviet Union on 4 October, while the ground units were transported back by train to Mannheim on 13 October. Since 22 June 1941, III.
Gruppe had claimed 769 aerial victories for losing 6 pilots killed, 7 missing in action, 2 captured and 12 wounded.
North Africa and Malta After its return to Germany, III.
Gruppe was deployed to the
Mediterranean Theater. The ground elements of III.
Gruppe arrived in
Catania in
Sicily on 28 November 1941. Wilcke and his adjutant
Jürgen Harder arrived on 2 December, with the rest of the
Gruppe arriving the next day. On 6 December 1941, III.
Gruppe was ordered to move to
Timimi in
Libya. Wilcke claimed his 34th aerial victory on 11 December, during a fighter escort mission for
Junkers Ju 88 bombers attacking
Bir Hakeim. III.
Gruppe relocated back to Sicily on 17 December 1941 for operations in the
siege of Malta. The island of
Malta had a strategically important position in the
Mediterranean Sea. With the opening of a
new front in North Africa in mid-1940, British air and sea forces based on the island could attack Axis ships transporting vital supplies and reinforcements from Europe to North Africa. To counter this threat, the Luftwaffe and the
Regia Aeronautica (Italian Royal Air Force) conducted bombing raids to neutralize the RAF defenses and the ports. During the siege, Wilcke claimed four victories over RAF fighters in April–May 1942. He claimed his first victory during the siege, and 35th overall, over a Spitfire fighter on 2 April 1942. His 36th aerial victory on 22 April may have been Hurricane (Z4011) "B" of
No. 185 Squadron flown by
Pilot Officer "Sonny" Ormrod, who was killed in the engagement. On 12 May 1942, III.
Gruppe destroyed nine Spitfires, among them one by Wilcke.
Wing commander of JG 3 On 18 May 1942, Wilcke was transferred to
Jagdgeschwader 3 "Udet" (JG 3—3rd Fighter Wing), named after the World War I fighter ace
Ernst Udet. Operating on the Eastern Front, Wilcke became a
Geschwaderkommodore of JG 3 "Udet" on 11 August, replacing
Oberst (Colonel)
Günther Lützow, who was posted to the staff of the
General der Jagdflieger (General of Fighters) as
Inspector of the Day Fighters on the Eastern Front. Operating from the
Chuguyev Airfield, JG 3 "Udet" saw combat in the
Kharkov area, present-day Kharkiv, during the
Second Battle of Kharkov. On 26 June 1942, JG 3 "Udet" was assembled at
Schtschigry on the southern sector of the Eastern Front for the upcoming summer offensive, supporting the
Wehrmacht's advance towards
Stalingrad. In the following months, JG 3 "Udet" was based at airfields at
Gorshechnoye, Olkhovatka,
Millerovo, Nowy-Cholan,
Frolovo, Tuzov and
Pitomnik. On 13 June 1942, Wilcke claimed his first victory with JG 3 "Udet", shooting down a
Lavochkin-Gorbunov-Gudkov LaGG-3 fighter for his 39th victory. He followed this with another LaGG-3 on 22 June, and a LaGG-3 and a
Polikarpov R-5 reconnaissance bomber on 24 June 1942. On 3 July 1942, he claimed three
Douglas Boston medium bombers, followed by two LaGG-3s and another Boston the next day. He became an "ace-in-a-day" again on 6 July, shooting down a
Bell P-39 Airacobra, a LaGG-3, an R-5 and three Hurricanes. Three days later, he shot down two
Ilyushin Il-2 Sturmovik
ground-attack aircraft and, on 10 July, four more Bostons. The next day, he claimed another R-5 and two
Mikoyan-Gurevich MiG-1 fighters. On 12 July, he again claimed an R-5 and two LaGG-3s before he shot down another LaGG-3 on 18 July. On 24 July he was credited with a
Polikarpov I-153 biplane fighter and two days later two Hurricanes and two Pe-2s. On both 27 and 28 July, he claimed victory over a LaGG-3, his last victory in July 1942. Wilcke's first victories in August 1942, a
Sukhoi Su-2 light bomber followed by two LaGG-3s, occurred on 5 and 6 August. On 9 August he filed a victory claim for an unknown aircraft type, bringing his "score" to 79 aerial victories. He took command of JG 3 "Udet" and achieved his first victory as
Geschwaderkommodore on 12 August, again over an unknown type of aircraft. He claimed eight further victories of unknown types: two on 13 August, one on 17 August, three on 20 August, and two on 23 August. His first victory on 26 August was identified as a
Yakovlev Yak-7 fighter; the other two that day were again of unknown types. Another series of unidentified aircraft shot down followed. He claimed one aircraft destroyed on 28 August, one more on 30 August and four on 31 August, taking his total to 96 aerial victories by the end of August 1942. Wilcke claimed his next two victories on 3 September and two more on 6 September, all four of unknown types of aircraft. This brought his total to 100 aerial victories. Wilcke was the 20th Luftwaffe pilot to achieve the century mark. On 9 September 1942, he became the 122nd officer or soldier of the Wehrmacht honored with the
Knight's Cross of the Iron Cross with Oak Leaves ().
Battle of Stalingrad From 10–19 September 1942, Wilcke claimed another series of victories over aircraft of unknown type, which included one on 10 September, one on 12 September, four on 18 September, and two on 19 September. On 16 September 1942, the Soviets launched an offensive north of Stalingrad. Wilcke led about 40 serviceable German fighters against the Soviet
8 Vozdyshnaya Armiya (8 VA—8th Air Army),
16 Vozdyshnaya Armiya (16 VA—16th Air Army), and 102 ''Istrebitel'naya Aviatsionnaya Diviziya Protivo-Vozdushnaya Oborona
(102 IAD PVO—Fighter Aviation Division of the Home Air Defense) over Stalingrad. At the time, Wilcke often flew with Hauptmann
Walther Dahl as his wingman. On 20 September 1942, Wilcke shot down two LaGG-3s. Two days later, he shot down six Yakovlev Yak-1 fighters over Stalingrad, his third "ace-in-day" feat, taking his total to 116 aerial victories. It is possible that one of his opponents was Leytenant (Second Lieutenant) Nikolai Karnachyonok of 434 Istrebitel'nyy Aviatsionyy Polk'' (434 IAP—434th Fighter Aviation Regiment), who was killed in action that day and was
posthumously made a
Hero of the Soviet Union. The
Geschwaderstab (headquarters unit) was based at the Pitomnik Airfield from 23 September to 21 November 1942. There Wilcke directed fighter operations for the
Battle of Stalingrad. During the previous offensive towards Stalingrad, the
Geschwaderstab of JG 3 "Udet" had claimed 137 victories, of which 97 victories were credited to Wilcke. While based at Pitomnik, Wilcke claimed four victories on 24 September, one on 25 September, three on 28 September, four on 29 September, one on 3 October, and two more on 24 October. On 25 and 26 October he claimed one victory on each day and his final two while based at Pitomnik on 1 November 1942, taking his personal total to 135 victories. For these achievements, he received the
German Cross in Gold (), awarded on 3 November 1942. In the encirclement's aftermath of the
6th Army on 23 November 1942, the
Geschwaderstab was moved to
Morozovskaya-West, outside the Stalingrad pocket. Wilcke organized fighter escort missions for the transport aircraft delivering supplies for the 6th Army. Pressed by the advancing Soviet armored spearheads, Morozovskaya-West had to be abandoned by the
Geschwaderstab on 23 December, and the aircraft were moved to Morozovskaya-South, which was not yet threatened by the Soviet Army. On 3 January 1943, this airfield had to be abandoned as well, and the
Geschwaderstab was relocated to
Tazinskaya; there it remained until the fighting over the Stalingrad pocket ended. During this period the
Geschwaderstab claimed 25 victories, 21 by Wilcke and 4 by Dahl, for the loss in action of two pilots. Wilcke claimed two victories on 24 November 1942, an Il-2 Sturmovik and a Yak-1, his first victories to support the Stalingrad pocket. On 30 November he claimed the destruction of three aircraft of unknown type, one more on 2 December, and three more on 8 December. Four victories claimed on 12 December, one
Lavochkin La-5 and three Yak-1s, took his total to 148 aerial victories. Wilcke became the fourth German fighter pilot to achieve 150 aerial victories in combat. He achieved this mark on 17 December 1942, claiming victories 149–151. The next day he claimed victory over three more aircraft. Following this 154th victory, he was awarded the
Knight's Cross of the Iron Cross with Oak Leaves and Swords () on 23 December 1943, the 23rd member of the Wehrmacht to be so honored. Along with the Swords came the ban from flying further operational combat missions. Although banned from flying, he was credited with two more victories on the Eastern Front: a Yak-1 on 28 December and an aircraft of an unknown type on 5 January 1943. In March 1943, Wilcke led
Geschwaderstab and II. and III.
Gruppe during operations against the
Kuban bridgehead as part of the
IV. Fliegerkorps (4th Air Corps). In early May 1943, the
Geschwaderstab was ordered out of action and returned to
München-Gladbach, present-day Mönchengladbach. Wilcke had only the
Geschwaderstab and I.
Gruppe under his effective command, and no further combat missions were flown until October 1943.
Defense of the Reich and death Wilcke was promoted to
Oberst on 1 December 1943 and requested permission to fly operationally and lead his
Geschwader from the air. In February 1944, although still officially banned from flying operations, Wilcke ignored the order and flew several missions leading his
Stabsschwarm against the
United States Army Air Forces (USAAF) in
Defense of the Reich missions. He claimed his 157th victory, over a
Lockheed P-38 Lightning, on 10 February and his 158th, over a
Consolidated B-24 Liberator, on 24 February. He shot down two
Boeing B-17 Flying Fortress bombers on 4 March 1944, his 159th and 160th aerial victories. On 6 March, his Bf 109 G-6 was crippled in aerial combat, and he made an emergency landing at
Neuruppin. Combat on 6 March cost both sides heavy losses. The
Eighth Air Force lost 75 four-engined bombers and 14 escort fighters; the Luftwaffe lost 65 aircraft; 36 German pilots were killed and 27 wounded. On 23 March 1944, Wilcke led JG 3 "Udet" against a USAAF bomber formation near
Braunschweig. On this day, the USAAF was attacking aircraft factories at Braunschweig and other targets of opportunity in
Münster,
Osnabrück, and
Achmer. The Eighth Air Force had committed 768 B-17s and B-24s bombers to this attack, supported by 841 long-range fighters. The Luftwaffe countered this attack with 13 day fighter
Gruppen, mustering 259 fighters on this day. Following combat, the Luftwaffe claimed the destruction of 51 enemy aircraft, including 44 four-engined bombers. The Luftwaffe suffered 16 pilots killed and six wounded, as well as 33 aircraft lost. The USAAF reported the loss of 29 bombers and 5 escort fighters while claiming 62 German aircraft shot down and another 2 destroyed on the ground. During this engagement, Wilcke shot down a B-17 Flying Fortress bomber and a
North American P-51 Mustang fighter, but was then shot down in his Bf 109 G-6 (
Werknummer 160 613—factory number) near
Schöppenstedt. It is assumed that the victors were
Captain Don Gentile and Captain
John T. Godfrey of the
4th Fighter Group. By this date, Wilcke had claimed 162 enemy aircraft in 732 combat missions. Wilcke had been nicknamed "
Fürst" (prince) by his comrades on account of his attitude towards his men and paternal sense of responsibility, and his being very conscious of his style and appearance and therefore wearing a very expensive and custom tailored leather coat. His funeral ceremony was held at the airfield in
Mönchengladbach (then "München Gladbach"). The funeral ceremony was attended by his stepfather, among others. Wilcke was buried in the honor section of the cemetery in Mönchengladbach-Holt next to the grave of
Klaus Quaet-Faslem.
Major Friedrich-Karl Müller succeeded Wilcke as commander of JG 3. ==Summary of career==
