Karl Kempf

Operation Barbarossa

At Stolp-Reitz, JG 54 upgraded their aircraft to the Bf 109 F-2. For the next four weeks, the pilots familiarized themselves with the new aircraft before on 15 June, III. Gruppe was ordered to Blumenfeld in East Prussia, present-day Karczarningken in the Kaliningrad Oblast, in preparation for Operation Barbarossa, the invasion of the Soviet Union. During the upcoming invasion, JG 54 would be deployed in the area of Army Group North, was subordinated to I. Fliegerkorps (1st Air Corps) and supported the 16th and 18th Army as well as the Panzer Group 4 in their strategic objective to reach Leningrad.^[13] On 23 June, Kempf claimed his first aerial victory on the Eastern Front, a Tupolev SB bomber.^[14]

On 26 June, LVI Panzer Corps under command of General der Infanterie Erich von Manstein had reached Daugavpils in southern Latvia. A formation of Soviet Tupolev SB bombers attempted to attack Manstein's forward Panzer columns. The bombers were intercepted by 7. Staffel of JG 54 claiming eight bombers shot down, including four credited to Kempf.^[15][16] Three days later, Kempf's Bf 109 F-2 (Werknummer 8113—factory number) suffered engine failure, resulting in a forced landing southwest of Daugavpils.^[17] Flying in the combat area of Leningrad on 17 September, Kempf became an "ace-in-a-day", claiming five aerial victories, taking his total to 23. His first claim of the day killed Mladshiy Leytenant Yegor Novikov [ru], a Hero of the Soviet Union, from 191 IAP (Istrebitelny Aviatsionny Polk—Истребительный Авиационный Полк or Fighter Aviation Regiment) near Krasnoye Selo.^{[18][19][Note 2]}

By the end of 1941, Kempf was credited with 36 aerial victories and had been awarded the German Cross in Gold (Deutsches Kreuz in Gold) on 24 November.^{[10][Note 3]} On 2 January 1942, Kempf again became an "ace-in-a-day", claiming five aerial victories including a Petlyakov Pe-2 bomber over the Siverskaya Airfield.^[21] He was awarded the Knight's Cross of the Iron Cross (Ritterkreuz des Eisernen Kreuzes) on 4 February 1942 following his 41st aerial victory.^[22][23] On 11 June, Kempf's Bf 109 F-4 (Werknummer 13143) was hit by anti-aircraft artillery leading to a forced landing 15 kilometers (9.3 miles) north of Novgorod.^[24] In September 1942, Kempf was transferred and became a fighter pilot instructor, first with Ergänzungs-Jagdgruppe Ost and then with Ergänzungs-Jagdgruppe West.^[10]

On the Western Front and death

In late May 1943 after a tour as an instructor, Kempf was posted to 11. Staffel of JG 54 which was based on the Western Front in defense of the Reich.^[25] 11. Staffel of JG 54 had its origin from 11. Staffel of Jagdgeschwader 26 "Schlageter" (JG 26—26th Fighter Wing). In January 1943, the Luftwaffe had planned to move JG 26 to the Eastern Front in exchange JG 54 which supported Army Group North. In order to keep up operations, the exchange was planned by rotating each Gruppe by Gruppe and every Staffel by Staffel. In this context, 11. Staffel of JG 54 was to be integrated into II. Gruppe of JG 54. On 22 May, 11. Staffel of JG 54 was ordered to Nordholz Airfield where it was subordinated to III. Gruppe of JG 26. The Staffel was ordered to Lille-Vendeville on 15 June where it was briefly controlled by the Geschwaderstab (headquarters unit) of JG 26. On 1 July, the Staffel was renamed and again became 11. Staffel of JG 26, a Staffel of III. Gruppe. Here on 16 August, Kempf claimed his first aerial victory while flying with JG 26 when he shot down a Douglas A-20 Havoc bomber, also known as "Boston", in a location 5 kilometers (3.1 miles) north of Auxi-le-Château.^[26]

On 1 December, Kempf claimed his first heavy bomber. That day, he shot down a Boeing B-17 Flying Fortress near Zülpich on a United States Army Air Forces (USAAF) VIII Bomber Command mission to Solingen.^[27] On 20 December, VIII Bomber Command flew a mission against Bremen. Defending against this attack, III. Gruppe pilots claimed five B-17 bombers shot down without loss, including one by Kempf.^[28] Two days later, Kempf was shot down and wounded in aerial combat with a B-17 bomber. Hit by the defensive fire of a B-17, he was forced to bail out of his Bf 109 G-6/U4 (Werknummer 440012) near Rheine on the Dortmund–Ems Canal, keeping him grounded for some time.^[29][30]

After the Allies launched Operation Overlord, the invasion of Normandy on 6 June 1944, Luftflotte Reich sent additional units to the invasion front. By 8 June, Jagdgeschwader 1, Jagdgeschwader 3, Jagdgeschwader 11 and III. Gruppe of JG 54 had arrived in France and were subordinated to Fliegerkorps II. III. Gruppe of JG 26 was based at Villacoublay Airfield.^[31] On 7 June, Kempf claimed the destruction of two Republic P-47 Thunderbolt fighter east of Dreux.^[32]

On 3 September, JG 26 retreated from Belgium with Geschwaderstab and I. Gruppe headed for Krefeld Airfield, II. Gruppe to Kirchhellen, now part of Bottrop, and III. Gruppe to München Gladbach. At Grimbergen Airfield, 2. Staffel was last to take off and immediately came under attack of six to eight North American P-51 Mustang fighters from the 38th Fighter Squadron of the 55th Fighter Group. In this attack, four Focke-Wulf Fw 190 fighters of 2. Staffel were shot down, including Kempf who was killed in action. His Fw 190 A-8 (Werknummer 171739) crashed near Baal.^[33][34] His victor may have been Lieutenant Darrel Stuart Cramer.^[10]

Aerial victory claims

According to US historian David T. Zabecki, Kempf was credited with 65 aerial victories.^[35] Spick also lists him with 65 aerial victories claimed in 445 combat missions. Of this figure, 49 aerial victories were claimed on the Eastern Front and 16 over the Western Allies, including two four-engine bombers.^[36] Mathews and Foreman, authors of Luftwaffe Aces — Biographies and Victory Claims, researched the German Federal Archives and found records for 64 aerial victory claims. This figure includes 49 aerial victories on the Eastern Front and another 15 on the Western Front, including three four-engined bombers.^[37]

Victory claims were logged to a map-reference (PQ = Planquadrat), for example "PQ 29173". The Luftwaffe grid map (Jägermeldenetz) 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 about 360 square miles (930 km²). These sectors were then subdivided into 36 smaller units to give a location area 3 km × 4 km (1.9 mi × 2.5 mi) in size.^[38]
