The large port city of Hamburg was very heavily bombed many times by the Royal Air Force (RAF) and the United States Army Air Forces (USAAF) during World War II. During one of the attacks in July 1943 a firestorm was created that caused many thousands of casualties.

Battle of Hamburg

The Battle of Hamburg codenamed Operation Gomorrah was a series of air raids conducted by the RAF on the city of Hamburg beginning in the end of July 1943. It was at the time the heaviest assault in the history of aerial warfare and was later called the Hiroshima of Germany by British officials.

The operation was originally formulated by British Air Marshal Arthur "Bomber" Harris (who famously said of the Germans "They have sowed the wind and so shall they reap the whirlwind") and was actually a joint effort between the RAF Bomber Command, the RCAF, and the USAAF (specifically 8th Air Force Bomber Command), who combined to create an "around-the-clock" bombing mission spanning 8 days and 4 nights--the Americans conducting the daylight raids with the British following after nightfall. Harris signed the order for the operation "Bomber Command Order No. 173" on May 27th.

The operation was conducted almost a month later. On July 24, at approximately 00:57AM, the first bombing started by the RAF and lasted almost an hour. A second daylight raid by US Air Force was conducted at 2:40PM. A third raid was conducted on the morning of the 26th. The night attack of July 26 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) 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 July 27, shortly before midnight, 739 aircraft attacked Hamburg. A number of factors combined to give the enormous destruction that followed; the unusually dry and warm weather, the concentration of the bombing in one area and that the city's firefighters were unable to reach the initial fires - the high explosive "Cookies" used in the early part of the raid had prevented them getting into the center of the city from the periphery where they were working on the results of the 24th. The bombings culminated in the spawning of the so-called "Feuersturm" (firestorm). Quite literally a tornado of fire, this phenomenon created a huge outdoor blast furnace, containing winds of up to 240 km/h (150 mph) and reaching temperatures of 800°C (1,500°F). It caused asphalt on the streets to burst into flame, cooked people to death in air-raid shelters, sucked pedestrians off the sidewalks like leaves into a vacuum cleaner and incinerated some eight square miles (21 km²) of the city. Most of the casualties (40,000) caused by Operation Gomorrah happened on this single night.

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

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 dropped, and 250,000 houses destroyed. 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 during the war, 440 were lost over Hamburg.

Time line of Hamburg air raids during World War II

Bombing raids by the RAF on Hamburg took place:RAF Bomber Command Campaign Diary
  • The night of 10/11 September 1939: 10 aircraft dropped leaflets.
  • The nights of 15/16 November and 16/17 November 1940: A heavy raid by a total of over 200 aircraft. On the first night damage was caused to the Blohm & Voss shipyard and over 60 fires were started. On the second night only 60 aircraft found their target and damage was far less. 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.
  • The night of 12/13 March 1941: heavy raids on Hamburg, Bremen and Berlin by a total of 257
  • The night of 13/14 March 1941: 51 people were killed, the highest number in a single raid to date

  • The night of 26/27 July 1942: Large raid by 403 aircraft. Widespread damage was caused, mostly in housing and semi-commercial districts rather than in the docks and industrial areas. At least 800 fires started, 523 of which were large. 823 houses were destroyed and more than 5,000 damaged. More than 14,000 people were bombed out. 337 people were killed and 1,027 injured. 29 aircraft were lost, 7.2 % of the force.
  • The night of 28/29 July 1942: large raid by 256 aircraft. Bad weather meant only 68 bombed in the target area. 56 fires, 15 of them large, were started. 13 people were killed and 48 injured. Bomber losses were high, 15.3 % for the main group bombing that night.

  • The night of 30/31 January 1943: medium raid by 148 aircraft. It was the first H2S radar attack of the war. H2S use was not successful and the bombs were scattered. However 119 fires were started of which 71 were large. 58 people were killed and 164 injured. 5 aircraft were lost, 3.4 % of the force.
  • The night of 3/4 February 1943: heavy raid by 263 aircraft. Bad weather affected the bombers with many turning back early. Damage was light for what was planned to be a large raid. 16 bombers were lost, 6.1 % of the force, many to night fighters.
  • The night of 3/4 March 1943: heavy raid by 417 aircraft. The pathfinders marked the wrong target, mistaking a mud bank for the docks with their H2S radar, so most of the bombs landed 13 miles downstream from the centre of Hamburg, around the small town of Wedel. Those bombs which landed on Hamburg did considerable damage starting 100 fires, killing 27 people and injuring 95. The damage to Wedel was extensive. 10 aircraft lost, 2.4 % of the force.
  • The night of 13/14 April 1943: nuisance raid by 2 Mosquitos.
  • The night of 26/27 June 1943: nuisance raid by 4 Mosquitos.
  • The night of 28/29 June 1943: nuisance raid by 4 Mosquitos.
  • The night of 3/4 July 1943: nuisance raid by 4 Mosquitos.
  • The night of 5/6 July 1943: nuisance raid by 4 Mosquitos.
  • The night of 24/25 July 1943: large raid by 791 aircraft, marked the opening of the "Battle of Hamburg". A countermeasures 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.
  • The night of 25/26 July 1943: diversionary nuisance raid by 6 Mosquitos.
  • The night of 26/27 July 1943: nuisance raid by 6 Mosquitos.
  • The night of 27/28 July 1943: large raid by 787 aircraft guided in by Pathfinders using H2S. Bombing about 2 miles east of city centre. Because of the unseasonally dry conditions, a firestorm was created in the built-up working-class districts of Hammerbrook, Hamm and Borgfelde. 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.
  • The night of 28/29 July 1943: nuisance raid by 4 Mosquitos.
  • The night of 28/29 July 1943: large raid by 777 aircraft guided in by pathfinders using H2S. The plan was to bomb the untouched northern suburbs. But a mistake in making led to the bombing of an area just south of the area devastated by the firestorm three night 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. 28 aircraft 3.6 % of the force was lost.
  • The night of 2/3 August 1943: A large raid by 740 aircraft dispatched on a raid to Hamburg but bad weather stopped all but a few bombers reaching Hamburg; many bombed secondary targets instead. 30 aircraft, 4.1 % of the force was lost.
