# Bombing of Düsseldorf in World War II

"none" is preferred when the title is sufficiently descriptive; see [[WP:SDNONE]]
During World War II, Düsseldorf was heavily destroyed by Allied aerial bombardment. The most severe attack occurred on June 12, 1943, when a firestorm was ignited through targeted bombing by the British Royal Air Force, largely destroying the historical city center, downtown, and other adjacent neighborhoods.

## Background

Düsseldorf had been a focal point of British air raids since the beginning of the war. The first British air raid on May 14, 1940, targeted the districts of Flingern and Oberbilk, hitting Hermannplatz and Dorotheenstraße, causing minor damage and resulting in seven injuries and one fatality. On December 7, 1940, approximately 700 incendiary bombs and about 50 explosive bombs fell on the city center, Pempelfort, Flingern, Oberbilk, and Benrath. Numerous more minor attacks followed. On the night of August 1, 1942, the people of Düsseldorf experienced the first major attack. This initial major attack marked the beginning of a series of assaults that ended with the destruction of more than half of Düsseldorf's buildings. The town hall was heavily damaged in another significant attack on September 11, 1942.
In total, over 243 attacks claimed the lives of more than 6,000 civilians.

## First major attack on the night of August 1, 1942

During the 113th air raid on Düsseldorf on August 1, 1942, the first major attack, a British squadron dropped nearly 14,000 incendiary bombs, primarily over the city center, Oberkassel, and the southern neighborhoods. For the first time, the Königsallee was also hit, and significant damage occurred, especially in the area of Oststraße and Friedrich-Ebert-Straße.
Düsseldorf mourned approximately 250 victims, while the neighboring city of Neuss had 34 casualties. About 12,000 residents were left homeless by the attack. Following the raid, 314 residential buildings were completely destroyed, 654 heavily damaged, 1,628 moderately damaged, and 9,030 lightly damaged. Various public buildings, industrial facilities, and Wehrmacht installations were also affected.
On that night, anti-aircraft guns and night fighters caused some of the 630 participating bombers to crash. A Wellington bomber crashed near Düsseldorf-Knittkuhl.

## Attack on June 12, 1943

The precise selection of neighborhoods to be bombed was based on aerial photographs, population density maps, and fire insurance cadastre maps. The cadastre maps had been deposited by German fire insurance companies with British reinsurance companies before the war. The historic Old Town of Düsseldorf was chosen as the core area of the attack because it had the highest proportion of wood in the total building mass, making it the optimal core target area for igniting a firestorm in Düsseldorf.
Before the bombardment, the target area was delineated by Mosquito fast bombers using red and green marker flares. This was monitored by a master bomber flying at high altitude, who was in radio contact with the marker aircraft. The attack began at 1:15 am with the deployment of the marker flares.

### Bombing

The target area was the densely populated city center, especially the Old Town. The bombing commenced at 1:25 am, lasting for an hour and 20 minutes. Initially, 1,300 explosive bombs and several hundred air mines were dropped. The shock waves from the explosions tore open roofs. Subsequently, over 225,000 electron-thermite incendiary bombs were dropped over the city, falling into the exposed roof structures of the houses and setting them ablaze in a very short time. Within an hour, thousands of smaller building fires merged into a firestorm. In the attacked districts of Derendorf, Düsseldorf-Center, and the south side of Düsseldorf, a 4,000-hectare (9,900-acre) sea of fire emerged, totaling about 9,000 individual fires.

### Damages and casualties

During this major attack, approximately 600 people were killed, and more than 3,000 people were injured. Among the structures destroyed or heavily damaged were 16 churches, 13 hospitals, 28 schools, and several thousand residential buildings. Large parts of the city center, including Derendorf, Carlstadt, Friedrichstadt, Unterbilk, Bilk, Oberbilk, and the Southside, were utterly destroyed. Extensive damage occurred between Reeser Platz in the north and Klinikum in the south.

### Further attacks and damage

Another major attack on the night of November 3–4, 1943, claimed 622 lives.$^{:369}$ Even greater damages occurred on the night of April 22–23, 1944, when 1,200 people were killed, and 20,500 became homeless.$^{:374}$ A major attack on the night of November 2–3, 1944, resulted in 748 deaths and 15,000 homeless.$^{:380}$
Subsequent attacks followed, leaving a massive devastation in Düsseldorf until the end of the war, with a total of 1.14 million incendiary bombs. In the core city area, 93% of all residential buildings, 96% of public buildings, and 93% of commercial buildings were destroyed or damaged. A large portion of the 535,000 residents at the beginning of the war had fled the city. At the war's end, fewer than 250,000 people lived amidst the ruins. 10 million cubic metres (350 million cubic feet) of debris had to be cleared.

### Reception

The air raid on June 12, 1943, was explicitly mentioned by British Prime Minister Winston Churchill in a speech he delivered on June 30, 1943, during the Honorary Freedom of the City of London award ceremony. According to Churchill, this attack vividly demonstrated the superiority of the British Royal Air Force. In Düsseldorf, the air raid on June 12, which occurred on the Saturday before Pentecost in 1943, became known as the Pfingstangriff (Pentecost Attack).
