Cologne's Catastrophe: Why The City Was Bombed

Cologne, a German city, was bombed in 262 separate air raids by the Allies during World War II, including 31 times by the Royal Air Force (RAF). The first bombing took place on 12 May 1940, but the most notable attack on Cologne was the first Allied 1,000 bomber raid on 30/31 May 1942. The RAF dropped a total of 34,711 long tons of bombs on the city, and 20,000 civilians died during the war in Cologne due to aerial bombardments.

The first-ever thousand-bomber raid by the RAF was conducted on Cologne during the night of 30–31 May 1942. Codename Operation Millennium, the massive raid was launched for two primary reasons: it was expected that the devastation from such raids might be enough to knock Germany out of the war or at least severely damage German morale; and the raids were useful propaganda for the Allies and particularly for RAF Bomber Command head Arthur Harris's concept of a Strategic Bombing Offensive.

The first bombing of Cologne took place on 12 May 1940

The German city of Cologne was bombed in 262 separate air raids during World War II, all by the Royal Air Force (RAF). While air raid alarms had gone off in the winter and spring of 1940 as British bombers passed overhead, the first bombing took place on 12 May 1940.

The first bombing of Cologne, Germany, took place on the night of 11-12 May 1940. It was one of 262 air raids on the city during World War II, all carried out by the RAF.

Cologne was not the first German city to be bombed in World War II. That distinction went to Freiburg in Breisgau, which was bombed on 10 May 1940, resulting in the deaths of 57 civilians, including 13 children. However, the first bombing of Cologne was notable for several reasons.

Firstly, it was one of the earliest bombings of a German city during the war, taking place just two days after the raid on Freiburg. Secondly, it marked the beginning of a sustained campaign of aerial bombardment against Cologne, which would eventually total 262 separate air raids. Finally, the bombing of Cologne represented a significant escalation of the air war, as it was the first time that the RAF had targeted a major German city.

The RAF had been carrying out aerial attacks on Germany since the early days of World War II, but these had primarily focused on military targets such as airfields and ports. The bombing of Cologne represented a shift in strategy, as the RAF sought to demoralize the German population and disrupt the war effort by targeting urban areas. This strategy would be employed to devastating effect in the following years, with cities such as Hamburg, Dresden, and Berlin suffering massive casualties and destruction.

The bombing of Cologne on 12 May 1940 was also significant because it demonstrated the RAF's growing capabilities. The raid involved a large number of aircraft, with some sources claiming that up to 100 bombers participated. This was a significant increase from previous raids and demonstrated the RAF's ability to carry out large-scale operations.

The raid also showcased the effectiveness of the RAF's new GEE navigation system, which allowed bombers to navigate and target with increased accuracy. This technology would be further refined and play a crucial role in the Allied bombing campaigns of later years.

The bombing of Cologne on 12 May 1940 caused significant damage to the city and resulted in civilian casualties. While the exact number of casualties is not known, it is clear that the raid caused widespread destruction and loss of life. The raid also had a significant psychological impact, as it brought the realities of aerial warfare to a major German city for the first time.

In the months that followed, Cologne would be subjected to further heavy bombing, including the first "thousand-bomber" raid on 30-31 May 1942, which caused even more extensive damage and casualties. However, the first bombing of Cologne on 12 May 1940 remains a significant event in the history of World War II, as it marked a turning point in the air war and presaged the massive aerial campaigns that would play a decisive role in the outcome of the conflict.

The most notable attack on Cologne was the first Allied 1,000-bomber raid on 30/31 May 1942

The most notable attack on Cologne during World War II was the first Allied 1,000-bomber raid on the night of 30/31 May 1942. Codenamed Operation Millennium, the raid was conducted by the Royal Air Force RAF Bomber Command under the leadership of Arthur Harris. Harris, Commander-in-chief of RAF Bomber Command from February 1942 until the end of the war, believed that extensive and sustained area bombing of Germany's most important cities might bring about a surrender without the need for a land attack. He also believed that incendiary bombs were more effective at wrecking cities than explosives alone.

The raid on Cologne was planned as a demonstration of the destruction a large force could inflict using the strategy of area bombing over a short space of time. Harris wanted to assemble a force of 1,000 bombers, a plan known as the Thousand Plan. The goal was to overwhelm German night fighter and flak defences by making a huge strike in a smaller 90-minute window. Hamburg was the original target, but poor weather conditions and the increased distance from Britain meant that Cologne was chosen instead.

The RAF drew additional bombers and pilots from nearly every available sphere to reach the 1,000-plane mark for the operation. This task was made more difficult when, at the last minute, RAF Coastal Command bombers were withdrawn from the operation. In total, 1,047 aircraft were used in the operation, with 868 striking the intended target area and 15 striking alternative targets. The RAF lost 43 aircraft (German sources claimed 44), 3.9% of the force sent on the raid.

The raid dropped a total of 1,478 tonnes (3.3 million pounds) of bombs on the city, two-thirds of which were incendiaries. This started 2,000-2,500 separate fires, with 1,700 classed as "large" by the German fire brigades. Over 15,000 buildings were destroyed or damaged, including 1,500 factories. The city's networks of electricity, gas, water supplies, and transport networks were all severely damaged.

The casualty toll reached 469-486 killed and around 5,000 wounded. The vast majority of people had taken to the city's air-raid shelters or the cellars of their own buildings, which kept casualties lower than they might have been.

The Royal Air Force dropped 34,711 long tons of bombs on the city

During World War II, the German city of Cologne was bombed in 262 separate air raids by the Allies, including 31 times by the Royal Air Force (RAF). Between 1939 and 1945, the RAF dropped 34,711 long tons of bombs on the city, and 20,000 civilians died as a result of aerial bombardments.

The first bombing took place on May 12, 1940, but the most notable attack on Cologne was the first Allied 1,000-bomber raid on May 30-31, 1942. Codename Operation Millennium, the massive raid was conducted for two primary reasons:

• It was expected that the devastation from such raids might be enough to knock Germany out of the war or severely damage German morale.
• The raids were useful propaganda for the Allies, particularly for RAF Bomber Command head Arthur Harris's concept of a Strategic Bombing Offensive.

Harris wanted to prove that Bomber Command could make a vital contribution to victory. By using bombers and men from Operational Training Units (OTUs), RAF Coastal Command, and Flying Training Command, Harris was able to gather 1,000 aircraft for the raid—two and a half times more than any previous raid by the RAF. However, just before the raid, the Royal Navy refused to allow the Coastal Command aircraft to participate due to the pressing threat of U-boats in the Battle of the Atlantic. Harris scrambled to crew 49 more aircraft with pupil pilots and instructors, and ultimately, 1,047 bombers took part in the raid.

The raid on Cologne used mostly incendiaries, and as a result, the majority of the damage was caused by the fires that they started. The Cologne fire brigade authority reported over 5,000 non-residential buildings were damaged, with 3,300 of those destroyed. There were over 1,700 fires classified as "large" by local authorities. The devastation of the raid was recorded by Hermann Claasen from 1942 until the end of the war and presented in his 1947 exhibition and book, "Singing in the Furnace: Cologne – Remains of an Old City."

20,000 civilians died in Cologne during World War II due to aerial bombardments

The German city of Cologne was bombed in 262 separate air raids during World War II, all conducted by the Royal Air Force (RAF). The first of these bombings took place on May 12, 1940, and the city would go on to be bombed 31 times by the RAF. The most notable attack on Cologne was the first Allied 1,000-bomber raid, which took place on the night of May 30-31, 1942. This raid was led by RAF Bomber Command under Arthur Harris and was intended to demoralize the German population and war effort.

During the raid, 868 aircraft bombed the main target, with 15 aircraft bombing other targets. A total of 1,478 tonnes (3.3 million pounds) of bombs were dropped, two-thirds of which were incendiaries. This resulted in 2,500 separate fires, with 1,700 classified as "large" by the German fire brigades. While the RAF lost 43 aircraft in this raid, the devastation caused by the attack was immense.

The raid on Cologne caused significant damage to the city and its civilian population. Over 5,000 non-residential buildings were damaged, with 3,300 of those completely destroyed. Additionally, 13,010 residential buildings were destroyed, 6,360 seriously damaged, and 22,270 lightly damaged. The attack also resulted in the destruction of several important cultural and historical sites, including churches, hospitals, schools, and universities.

The human toll of the raid was devastating, with 20,000 civilians losing their lives during World War II due to aerial bombardments in Cologne. This death toll included those who perished in the 1,000-bomber raid, where several hundred people died and thousands more were wounded. The casualty toll could have been much higher if not for the availability of air-raid shelters and deep cellars in the city.

The attack on Cologne exemplified the tragic impact of aerial bombardments on civilian populations during World War II. The massive loss of life and widespread destruction caused by these raids underscored the devastating consequences of war for innocent people caught in the crossfire.

The devastation of Cologne was recorded by Hermann Claasen from 1942 until the war's end

The German city of Cologne was subjected to 262 separate air raids by the Allies during World War II, including 31 by the Royal Air Force (RAF). The first of these bombings took place on May 12, 1940. However, the most notable attack occurred on May 30 and 31, 1942, when the RAF conducted the first 1,000-bomber raid in history. This massive assault was designed to demoralize the German population and cripple their war effort.

The devastation of Cologne during World War II was extensively recorded by German photographer Hermann Claasen. From 1942 until the war's end, Claasen captured haunting images of his city's ruins, creating a valuable historical record known as "Trümmerfotografie" ("rubble photography"). His work offers a unique perspective on the destruction wrought by the Allied bombing campaigns.

On the night of May 30, 1942, Cologne was devastated by the first of the RAF's 1,000-bomber raids on Germany. Over the course of an hour and a half, 1,046 bombers dropped approximately 1,500 metric tons of high-explosive and incendiary bombs on the city. The attack resulted in catastrophic damage, with 600 acres of Cologne flattened, including 90% of the city centre.

The raid caused immense destruction, with over 5,000 non-residential buildings damaged and 3,300 homes destroyed, leaving 45,000 people homeless. The casualty toll was significant, with 474 killed and 5,000 wounded. The human toll would have been much higher if not for the air-raid shelters and deep cellars that protected many residents.

Among the buildings damaged during the raid were culturally and historically significant structures, including churches, museums, and schools. Notably, 21 churches were heavily damaged or completely destroyed, including some of the most important treasures of German architecture such as "Maria im Kapitol," "St. Apostel," and "St. Gereon."

Despite the extensive destruction, the iconic Cologne Cathedral remained standing, its twin spires defiantly silhouetted against the night sky. This sight served as a source of resilience and determination for the people of Cologne, strengthening their morale throughout the remainder of the war.

Hermann Claasen, a native of Cologne, began documenting the devastation of his city after his studio and photo archive were destroyed in an attack on May 31, 1942. His "rubble photographs" offer a unique perspective on the aftermath of the bombings, capturing the contrast between the city's proud architectural heritage and its post-war ruins.

Claasen's work during this period was not without risk, as photography during the conflict was strictly prohibited. However, his efforts were legitimised by the Düren chief administrator's documentation of the destruction in nearby cities, which was later published in the booklet "Verbrannte Erde" ("Scorched Earth").

In 1947, Claasen published "Singing in the Furnace. Cologne - Remains of an Old City, a collection of his photographs that served as a powerful testament to the devastation wrought by the war. This publication was supported by Konrad Adenauer, the Mayor of Cologne until 1946.

Claasen's photographs of Cologne's devastation are distinguished by his application of the principles of picturesque German photography that predated World War I. His images often emphasised religious monuments and their remaining sculptural ornamentation, providing a poignant contrast between the city's rich historical heritage and its contemporary ruins.

One of Claasen's most arresting images, "Fronleichnamsprozession, 1946, captures a procession of nuns filing past the utter devastation of Cologne. This photograph, along with his other works, stands as a powerful testament to the resilience of the city and its people in the face of immense destruction.
