The Allied Bombing of Hamburg during World War II (September 1939-April 1945) included numerous strategic bombing missions and diversion/nuisance raids.As a large port and industrial center, Hamburg's shipyards, U-boat pens, and the Hamburg-Harburg area oil refinerieswere attacked throughout the war. Hamburg was also the site of the world's oldest dynamite factory, constructed by Alfred Nobel.

The attack during the last week of July, 1943, Operation Gomorrah, created one of the greatest firestorms raised by the RAF and United States Army Air Force in WWII, killing roughly 50,000 civilians in Hamburg and practically destroying the entire city. As with the bombing of other cities, the RAFand USAAFbombings of Hamburg employed a number of revolutionary strategies, including bombing the city center first in order to draw in the city's entire fire-fighting force, then dropping delayed action high-explosives in a concentric ring around the center, filling the streets with rubble and trapping the firefighters while they worked, ultimately incinerating them. This was followed by the dropping of further napalm and white-phosphorus incendiaries in a second concentric ring outside the first, facilitating unhampered burning in the remaining outer city. The circular bombing pattern , combined with a few days of unusually warm weather, was fundamental to creating the necessary vortex and whirling updraft of super-heated air needed to create the 1,500-foot-high tornado of fire. Various other new techniques and devices were instrumental as well, such as (e.g., area bombing), tactics (Pathfinders), and technologies (H2S radar), and 'Window' - clouds of shredded tinfoil dropped by pathfinders preceding the bomber stream in order to completely cloud German radar.

Significant missions

Battle of Hamburg

The Battle of Hamburg, codenamedOperation Gomorrah, was a campaign of air raids beginning 24 July 1943 for 8 days and 7 nights. It was at the time the heaviest assault in the history of aerial warfareand was later called the Hiroshima of Germanyby British officials.

The Battle of Hamburg overlapped the Battle of the Ruhrwhich ended on 31 July.

Gomorrah was originally formulated by British Prime Minister Winston Churchillwith help from Air Chief MarshalArthur "Bomber" Harris. The operation was conducted by RAF Bomber Command(including RCAFSquadrons) and the USAAF Eighth Air Force. The British conducted the night raids and the USAAF conducted the daylight raids.

On 24 July, at approximately 00:57AM, the first bombing started by the RAF and lasted almost an hour. A second daylight raid by US Army Air Force was conducted at 4:40PM. A third raid was conducted on the morning of the 26th. The night attack of 26 July at 00:20AM was extremely light due to a severe thunderstorm and high winds over the North Sea during which a considerable number of bombers jettisoned the explosive part of their bomb loads (retaining just the incendiaries) with only two bomb drops reported.That attack is often not counted when the total number of Operation Gomorrah attacks is given. There was no day raid on the 27th.

On the night of 27 July, shortly before midnight, 739 aircraft attacked Hamburg. The unusually dry and warm weather, the concentration of the bombing in one area, and firefighting limitations due to Blockbuster bombsused in the early part of the raid culminated in the so-called "Feuersturm"(firestorm). The tornadic fire created a huge inferno with winds of up to 240 km/h (150 mph)reaching temperatures of 800 °C (1,500 °F) and altitudes in excess of 1,000 feet, incinerating more than eight square miles (21 km²) of the city. Asphaltstreets burst into flame, and fuel oil from damaged and destroyed ships, barges, and storage tanks spilled into the waters of the canals and the harbor caused it to ignite as well. The majority of deaths attributed to Operation 'Gomorrah' occurred on this night. A large number of those killed died seeking safety in bomb shelters and cellars, the firestorm consuming all available oxygen in the burning city above. The furious winds created by the firestorm were rumored to have swept people up off the streets like dry leaves.

On the night of 29 July, Hamburg was again attacked by over 700 aircraft. The last raid of Operation Gomorrah was conducted on 3 August.

Operation Gomorrah caused at least 50,000 deaths, and left over a million German civilians homeless. Approximately 3,000 aircraft were deployed, 9,000 tons of bombs were dropped, and over 250,000 homes and houses were destroyed. No subsequent city raid shook Germany as did that on Hamburg; documents show that German officials were thoroughly alarmed, and there is some indication from later Allied interrogations of Nazi officials that Hitler stated that further raids of similar weight would force Germany out of the war. Hamburg was hit by air raids another 69 times before the end of World War II.

RAF Bomber Command lost 12 bombers on the first day of the attack. In total, 440 RAF aircraft were lost over Hamburg during the war.

Aftermath

Cityscape

The totally destroyed quarter of Hammerbrook, in which mostly longshoremen lived, was not rebuilt as housing area but as a commercial area.The adjoining quarter of Rothenburgsort shared the same fate, as only a small area of housing was rebuilt.The underground line which connected these areas with the central station was not rebuilt either.

In the destroyed residential areas many houses were rebuilt across the street and therefore do not form connected blocks anymore. The hills of the Öjendorfer Park are formed by the debris of destroyed houses.

Memorials

Several memorials in Hamburg remind at the air raids during World War II:

• The Nikolaikirche, which was largely destroyed during the bombing, has been made into a memorial against the war. The spire of the church, which was used by the bomber pilots as aiming point, endured the attacks.

• Memorial at the Hamburger Strasse - a memorial for those who died in a shelter under the Karstadt department store at the corner Desenißstrasse/Hamburger Strasse. The department store was hit by a bomb in the night of 30 July. The people in the air raid shelter below were killed by the heat and carbon monoxide poisoning.

• The victims of the air raids were buried on the Ohlsdorf cemetery in mass graves. The memorial "Passage over the Styx" by Gerhard Marcks is in the center and shows how Charon ferries a young couple, a mother with her child, a man and a desperate person over the river Styx.

• Many houses rebuilt after World War II show a memorial plaque with the inscription "Destroyed 1943 - ... Rebuilt" to remind of their destruction during the air raids in July 1943.

1. These two nights of bombing were only 24 hours after a very large raid by the German Luftwaffe on Coventry on the night of 14/15 November 1940. However the raid must have been planned more than 24 hours in advance, so although these raids are often stated to be revenge attacks, it is unlikely that they were planned to be so.

A countermeasure against the radar-directed German nightfighters in the form of "Window" was used for the first time. In the clear weather visual and H2S marking was accurate and on the town centre. 728 aircraft dropped their bombs in 50 minutes. Less than half the force bombed within 3 miles of the centre with a bomb creepback of six miles. Damage was caused in the central and north-western districts, particularly in Altona, Eimsbüttel and Hoheluft. The Rathaus (Town Hall), the St. Nikolai church, the main police station, the main telephone exchange and the Hagenbeck Zoo were among the well-known landmarks to be hit. About 1,500 people were killed which was the largest outside the range of the "Oboe" radio navigation system which helped to concentrate the bombing pattern. Thanks to the use of Window only 12 aircraft were lost, 1.5% of the force.

nuisance raid
6 Mosquitos attacked Hamburg.
night of 27/28 July 1943
787 aircraft guided in by Pathfinders using H2S bombed about 2 miles east of city centre. Due to the unseasonally dry conditions, a firestorm was created in the built-up working-class districts of Hammerbrook, Hamm, Borgfelde and Rothenburgsort. The bombing was more concentrated than the RAF was usually able to manage at this stage of the war. In just over half an hour it is estimated that 550-600 bomb loads fell into an area measuring only 2 miles by 1 mile and this gradually spread the fire eastwards. The firestorm lasted for about three hours, consuming approximately 16,000 multi-storyed apartment buildings and killing an estimated 40,000 people, most of them by carbon monoxide poisoning when all the air was drawn out of their basement shelters. Fearing further raids, two-thirds of Hamburg's population, approximately 1,200,000 people, fled the city in the aftermath.
night of 28/29 July 1943
nuisance raid
4 Mosquitos.
night of 29/30 July 1943:

But a mistake in mapping led to the bombing of an area just north of the area devastated by the firestorm three nights before. The residential areas of Wandsbek and Barmbek districts and parts of the Uhlenhorst and Winterhude were severely damaged and widespread fires but no firestorm. Twenty-eight aircraft 3.6% of the force was lost.
