Wieluń city center after the German air raid

The bombing of Wieluń refers to the bombing of the Polish town of Wieluń by the German Luftwaffe on 1 September 1939. The Luftwaffe started bombing Wielun at 4:40 am, five minutes before the shelling of Westerplatte, which has traditionally been considered the beginning of World War II. It is considered to be one of the first terror bombings in history and first in Europe in this war.[1] It killed an estimated 1,300 civilians, injured hundreds more and destroyed 90 percent of the town centre. There were no military targets of any importance in the area.[1] The casualty rate was more than twice as high as Guernica.[2]


According to German records 29 Junkers Ju 87B “Stukas” of Sturzkampfgeschwader 76 under the command of Captain Walter Sigel started from Nieder-Ellguth airfield at 5:02 am on 1 September 1939.[3] Some twenty minutes later they reached the town of Wieluń unopposed and dropped 29 bombs of 500 kg and 112 bombs of 50 kg.[3] Among the first places bombed was the hospital,[4] despite Red Cross markings; 26 patients were killed.[5] The attack on the hospital was investigated by German prosecutors in 1978 and 1983, but the charges were dropped, since prosecutors felt that the pilots could not make out the nature of the target due to poor lighting conditions at dawn.[3] Within the hour all 29 aircraft landed at Nieder-Ellguth, when Sigel reported no observation of enemy forces.[3]

A second wave of 29 Stukas of Sturzkampfgeschwader 2 Immelmann commanded by Major Oskar Dinort attacked the town shortly afterwards,[3] followed by a third wave at about 2:00 pm. In all, 380 bombs totalling 46,000 kg had been dropped on the town, hitting the hospital, killing more than 1,200 inhabitants and destroying 70 per cent of the buildings, up to 90 per cent in the center.[3] According to German documents the town was burning at 06:00 – "Wielun brennt" - Wieluń is burning.[5]

Journalists Sylwia Słomińska and Joachim Trenkner state that there were no military or industrial targets of note in the area,[5][6] except for a small sugar factory in the outskirts of the town. According to the two journalists, German bombers also destroyed the historical gothic church.

Other version of the events

German aviation historian Horst Boog claims that a Polish cavalry brigade and a Polish infantry division had been located in the town by German reconnaissance the day before the attack. From reports of Luftflotte 4, 2nd Air Division, I./Sturzkampfgeschwader 76 and I./Sturzkampfgeschwader 77 he concludes that the bomb attacks had been directed against these military formations and can therefore not be considered terror bombings. Due to ground fog, he argues, the German pilots missed their targets and mistakenly bombed the town.[7] British aviation historian Peter C. Smith[8] too, describes the bombing as collateral damage from bombs that missed their targets during ground support of the Wehrmacht operations.[8] Polish historian Jerzy B. Cynk, author of The Polish Air Force at War. The official history 1939-1943, wrote about the events: "Numerous direct support missions were also flown, with the heaviest attacks directed against the Polish cavalry and troop concentrations at Wielun."[9]

At 13:00 a German dive bomber wing, I./StG 2 led by Major Oskar Dinort via Nieder-Ellguth, were directed against this unit, followed a few hours later by Schwarzkopff with sixty Ju 87 Stukas of I./Sturzkampfgeschwader 77[8] Weather conditions were unfavourable during the day, with a visibility of only one kilometre and a practically closed layer of fog at 50 metres altitude.[10] Fog, mist and poor visibility thwarted many of the Luftwaffe's sorties planned for the morning of the first day of the invasion.[10] The dive bombers, facing intense anti aircraft fire, inflicted heavy losses on the Polish cavalry[when?], and the advance was turned into a rout by 90 Stukas.[8] On their return home, four of the German Junkers Ju 87 bombers were shot down by the Polish 36 Academic Legion Infantry Regiment stationed nearby.[8] Three waves of attacks were carried out during the day.[8] The town was captured by the German Army on the first day of the invasion.[8]
