Waldemar Semelka (8 January 1920 – 21 August 1942) was a German Luftwaffe military aviator and fighter ace during World War II. He is credited with 75 aerial victories, all on the Eastern Front, achieved in 240 combat missions.
Born in Dombrau, Semelka joined the military service in the Luftwaffe. Following flight training, he was posted to Jagdgeschwader 52 (JG 52—52nd Fighter Wing). Semelka claimed his first aerial victory on 22 June 1941, the first day of Operation Barbarossa, the German invasion of the Soviet Union. In June 1942, he was temporarily geven command of 5. Staffel (5th squadron) of JG 52. In late July, he was tasked with leading 4. Staffel of JG 52. Semelka was killed in action on 21 August 1942 near Srednyaya Akhtuba during the Battle of Stalingrad. Posthumously, he was awarded the Knight's Cross of the Iron Cross.
Military career
Semelka was born on 8 January 1920 in Dombrau, at the time in the Teschen District which after World War I became disputed land between the Czechoslovak Republic and the Second Polish Republic. Present-day, Dombrau is Doubrava in the Czech Republic.
Following flight training, Semelka was posted to 4. Staffel (4th squadron) of Jagdgeschwader 52 (JG 52—52nd Fighter Wing), a squadron of II. Gruppe (2nd group) of JG 52 in 1941. In preparation of Operation Barbarossa, the German invasion of the Soviet Union, II. Gruppe of JG 52, without a period of replenishment in Germany, was ordered to airfields close to the German-Soviet demarcation line. While the Gruppenstab (group headquarters unit) and 4. Staffel were based at Suwałki in northeastern Poland, 5. and 6. Staffel were transferred to a forward airfield at Sobolewo. For the invasion, II. Gruppe of JG 52 was subordinated to the Geschwaderstab (headquarters unit) of Jagdgeschwader 27 (JG 27—27th Fighter Wing). The Geschwader was part of the VIII. Fliegerkorps commanded by Generaloberst Wolfram Freiherr von Richthofen which supported the northern wing of Army Group Centre.
Operation Barbarossa
At the start of Operation Barbarossa on 22 June 1941, Semelka's 4. Staffel was headed by Oberleutnant Johannes Steinhoff and II. Gruppe was commanded by Hauptmann Erich Woitke. The Gruppe supported the advancing 9th Army and 3rd Panzer Group in their attack on the border fortifications east and southeast of Suwałki. Semelka claimed his first aerial victory on the morning of 22 June when he shot down a Polikarpov I-15 fighter. On 25 June, the Gruppe moved to an airfield at Varėna in Lithuania which had previously been occupied by the Soviet Air Forces (VVS—Voyenno-Vozdushnye Sily). Two days later, the Gruppe moved to Maladzyechna, supporting the advance Panzergruppe 3 near Barysaw. Flying from this airfield, Semelka claimed an Ilyushin DB-3 bomber shot down on 2 July. Two days later, the Gruppe moved to Sloboda, east of Minsk, before moving to an airfield named Lepel-West at Lyepyel on 5 July. From this airfield, II. Gruppe flew combat air patrols and fighter escort missions to combat areas near Vitebsk and Haradok, supporting Panzergruppe 2 and 3 in their advance to Vitebsk and Polotsk. Here, Semelka claimed the destruction of another DB-3 bomber on 6 July.
II. Gruppe was ordered to relocate to Soltsy, west of Lake Ilmen, on 5 August in support of the 16th Army and Army Group North. Here, the Gruppe supported the fighting south of Lake Ilmen, and the German attacks on Shlisselburg, Leningrad and the Soviet fleet at Kronstadt. Operating from Soltsy, Semelka claimed an I-17 fighter, an early war designation for the Mikoyan-Gurevich MiG-1, and a Vultee V-11 ground attack aircraft, probably referring to the Ilyushin Il-2, shot down on 14 August. On 24 August, II. Gruppe was ordered to an airfield at Spasskaya Polist on the river Polist, south of Chudovo and north of Novgorod on Lake Ilmen, supporting the 18th Army in its advance towards the Neva and Lake Ladoga. Semelka claimed three fighters while flying from Spasskaya Polist, one Polikarpov I-16 on 25 August and two I-17 fighters the following day.
