Conflict:
The devastating 1943 bombing of Hamburg shook the Nazi regime as never before.
RAF Bomber Command all but annihilated the German city of Hamburg at the close of July 1943. In the view of Air Chief Marshal Arthur T. Harris, the attacks on the so-called second city of the Reich were incomparably more terrible than any Germany had suffered to that point. The name bestowed on this series of raids seemed to fit its wrath-of-God nature. The RAF called it Operation Gomorrah.
The redoubtable Bomber Harris was right. His Bomber Command threw 2,355 sorties at Hamburg in three massive nighttime raids on July 24-25, July 28, and July 30. The United States Army Air Forces also flung itself into the attacks; Eighth Air Force, based in Britain, generated 235 daylight sorties in two raids during July 25 and July 26.
The main result was a horrendous July 28 firestorm that killed more than 40,000 persons in and around Hamburg. Most died of asphyxiation while huddling for shelter in their basements, or in the above-ground flames and melting asphalt of the streets.
By contrast, the Luftwaffes Nov. 14, 1940 firestorm-bombing of the English city of Coventry killed 538 Britons.
The Hamburg raid was a shock to the Fuehrer, Adolf Hitler, and his air force chief, Hermann Goering. Former reichsminister Albert Speer wrote years later, Hamburg had suffered the fate Hitler and Goering conceived for London in 1940.
The situation looked very different from the Allied side. Harris described the RAFs own losses (57 aircraft in the three raids) as minute. Hamburgs fate, in British eyes, could only be called just. What happened at Hamburg was what happened when Bomber Command got everything right,'" wrote historian Martin Middlebrook in his definitive 1980 account of the attacks, The Battle of Hamburg.
Few doubted that Bomber Command had taken the World War II air war to a new level.
Total Air War
It was a level that had been conceivedeven expecteda decade earlier. Prosecution of total war on cities and civilians as well as armies was part of interwar military thought in both England and Germany. In 1932, British Prime Minister Stanley Baldwin famously predicted, The bomber will always get through. The only defense is offense, which means that you have to kill more women and children more quickly than the enemy [does] if you want to save yourself.
The concept resonated with the Luftwaffe, according to American historian Williamson Murray. One Luftwaffe theoretician argued in May 1933 that terrorizing of the enemys chief cities and industrial regions through bombing would lead that much more quickly to a collapse of morale.
When war finally came, the Luftwaffe soon executed city-busting raids on England, notably in the blitz against London and the firebombing attack on Coventry. Nearly three years later, it would be the cities of the Third Reich suffering the effects of these tactics.
Despite the drift of strategic talk in the 1930s, neither the Luftwaffe nor the RAF built top-class strategic bomber fleets before the war. At Bomber Command, the first years of the air war featured only desultory bombing activity. Initial results were poor and losses high.
Then, in September 1941, Prime Minister Winston Churchill approved a plan to build 4,000 bombers, devoting one-third of the British war production capacity to the effort.
Churchill believed a bomber offensive against Germany was a way of breaking her war will, and he ranked the importance of the effort second only to the largest military operations which can be conducted on the Continent.
Churchill put Harris in charge of Bomber Command in early 1942. When it came to faith in the power of the bomber, there was no bigger believer than Harris. (See Bomber Harris, January 2005, p. 68.) He took over a command that was expending more than a quarter of its effort against naval targets, a policy he ridiculed as frightening cod. The campaign against German industrial targets got about the same level of effort.
Harris redirected the commands focus, turning it to the generation of mass city bombing.
The choice of tactics came from experience, not theory. Harris in 1942 had tried low-level daylight bombing with his new Lancaster bombers. The results had been disastrous, with the RAF losing many bombers for little gain. From a tactical perspective, Harris thought, the British experience showed that the only way to achieve results was to fly at night and to carpet-bomb entire city areas.
Hit the Workers
Harris pursued cities for tactical reasons, but he had a clear operational premise, too. De-housing the German workersand killing many of them along the waycould be as effective as blowing up factories, he concluded. Churchills science advisor, Lord Cherwell, calculated that 22 million Germans lived in the Reichs 58 largest cities and that turning them out of their homes would weaken German morale.
If you cant hit the works, hit the workers, Harris said in a famous, and infamous, formulation.
Ultimately, Bomber Command would do both. By the summer of 1943, Harris had built and trained a force geared for taking part in 1,000-aircraft night attacks on German cities. The Americans were ready for mass raids, too. However, the Allies faced a major problem: The air war in mid-1943 had not yet turned decisively in favor of the Allies, and, until it did, the whole plan for the Normandy invasion was at risk.
The most important task was gaining air superiority. Here the Allies were in a tough contest. The more they bombed Germany, the more fighters the Nazis pulled from the Mediterranean and other theaters to stiffen defenses. The Great Depression of the 1930s had left Germany with tremendous industrial overcapacity; war leaders quickly exploited this, and German fighter production actually grew in 1943.
The air war was at a crossroads. London and Washington, being slow in building their strength, had to use their bombers to cripple German industrial production before it was too late. The Americans geared up for August attacks on Schweinfurt and Regensburg. Harris picked Hamburg.
Many factors made Hamburg an ideal target. It was an industrial city, home to Blohm & Voss shipyards and hundreds of other, small manufacturers grouped around the city center. In addition, flying to Hamburg would be easier than flying to most other German cities. To reach Hamburg, the bomber stream could fly eastward over the North Sea, slip past anti-aircraft guns and night fighters in occupied Holland, and reach Hamburg without having to fly over more than a sliver of German land.
RAF Bomber Command crews had bombed Hamburg several times before, but this mission was different. Bomber Command had top-notch Lancaster bombers, trained crews, technical advantages, and a daylight partner in Eighth Air Force. Now, as Harris said, for the first time, the command found itself in a position, under suitable conditions, to inflict severe material damage on almost any industrial center in Germany.
Harris also had an ace in his sleeve. It was a supersecret radar electronic countermeasure, code-named Window. For more than a year, the RAF had been holding back on the use of Window, but Bomber Command pulled it out for the first Hamburg raid on the night of July 24-25, 1943.
Window was a huge advantage. One of the biggest problems confronting Bomber Command was the deadly combination of Luftwaffe night fighters and the radar warning system that controlled them. Grid boxes covered occupied Europe and each contained a night fightertypically a Bf-109 or Bf-110equipped with short-range cockpit radar. Prong antennae stuck out from the noses of the night fighters and gave their radars a range of about four miles in a 70 degree cone. The best, such as the He-219, could bag Lancasters seemingly at will and even take down the 400 mph Mosquito light bombers.
Long-range Freya radars picked up bombers at their assembly points about 80 miles from the British coast. From early 1942, the Luftwaffe also had a dense line of Wurzburg radars that gave ground controllers accurate vectors to the bombers. The Wurzburgs also assisted flak gun-laying.
Fool the Wurzburgs
Windows job was to fool the Wurzburgs. Window was tested and ready by early 1942, but then a strange self-deterrence took over and the RAF declined to use it.
Harris said the overriding reason the system did not go into use was the governments fear of retaliation in kind at a time when our own radar defenses could have been obliterated by the enemy use of Window. However, Harris scoffed at this concern. It was folly, he thought, to assume the Germans didnt know about electronic countermeasures.
The biggest mistake anybody can make, militarily, Harris said, is to credit themselves with being so damn clever that, between two evenly balanced industrial nations, you dare not disclose a particular weapon or device to the enemy for fear of giving him something he doesnt already have.
As the Hamburg raids approached, the power of the enemy defenses required drastic counteraction, said Harris.
The morning of July 24, 1943 began as a summer day should, warm and bright, wrote RAF Flight Lt. A.J.F. Davidson, who was already a veteran of 39 bomber missions over Europe. Soon word came that ops were on for the night and my gut began its familiar crawl.
For the 791 bomber crews who took off for Hamburg that night, Window was a new device. More than a few of them had doubts about whether it would work over heavily defended Hamburg.
Certainly the device didnt look like much. Thin aluminum strips, blackened on one side, were tied in bundles. A crew member crouched over a flare chute deep in the fuselage and hand-dispensed one bundle per minute until his bomber was out of Wurzburg range.
With more than an hours warning from the Freya radars, Hamburgs intricate defenses swung into action. Civilians took to shelters. Searchlights swept the skies and flak batteries slewed to engage the enemy aircraft.
Then the Window clouds flooded the Wurzburg radar screens with false returns. Ground control operators lost contacts. This version of Window befuddled cockpit radar, too. On the night fighter scopes, Window clouds forced the fighters to freelance, using only visual cues. Their only option was to turn back into the bomber stream and try to pick out the silhouette of a big four-engine Lancaster.
Window caused the crumbling of the integrated German defenses. Bomber crew reports after the first attack described searchlights waving aimlessly. RAF signals intelligence confirmed the confusion of the ground controllers hit with Window.
The first RAF raid was a success, shutting down parts of the water system, for example. Large-scale fires flared up again and again.
Fire Typhoon
It was the RAFs Raid Two that began the firestorm.
The RAF did not expect this. Hamburgs brick buildings and waterways seemed to render it a less-than-ideal target for incendiaries. Also, a major fire in 1842 had already taken out medieval timber buildings still found in some German city centers, such as Dresden.
Consequently the bomb loads on the July 28 raid combined high explosives plus batches of the four-pound incendiary sticks. More than 700 aircraft of the main force dropped 2,326 tons of bombs in a concentrated area about two miles from the city center. Incendiaries started thousands of fires. Hot, dry weather played a part.
Then came the conflagration.
About half way through the raid, the fires in Hammerbrook started joining together, noted an official RAF history. Superheated air of 600 degrees centigrade generated suction in the narrow streets and spun tempests where the overheated air stormed through the streets with immense force, according to a contemporary German Army report.
Suddenly, the whole area became one big fire, with surrounding air drawn into it with the force of a storm. The RAF bombing continued for another half-hour, spreading the firestorm area gradually eastward. It is estimated that 550 to 600 bomb loads fell into an area measuring only two miles by one mile.
The firestorm raged for about three hours and only subsided when all burnable material was consumed. Sixteen thousand apartment units vanished, along with more than 40,000 people. A German report called it a fire typhoon such as was never before witnessed, against which every human resistance was quite useless.
Human talessome inflated for propaganda purposes, yet all devastatingtold of the horror. A policeman wrote of finding a girl, black with soot, wandering aimlessly and dragging her dead little brother behind her. Official records put the dead at 13,000 men, 21,000 women and 8,000 children.
Rattling the Reich
Bomber Command, protected by Window, experienced light losses in the July raids. On previous missions to Hamburg, Bomber Command had lost six percent of each attacking force. This time, however, losses totaled only 57 aircraftjust 2.4 percent of the total.
Beyond the light attrition, both the immediate bomb damage and the ripple effects in Germany high politics were victories for Bomber Command.
When the smoke cleared, Harris later wrote, photos showed the heavily damaged areas covered at least 74 percent of Hamburgs closely built-up residential districts. The city docks and four main shipyards were damaged, with power and transport at a standstill. It was World War IIs first widespread destruction of a major city. It would not be the last.
Hamburgs survivors demonstrated determination, but more than a million moved out of the city. Yet it wasnt the workers who were rattled. It was Nazi officialdom. For the first time, after almost four years of war, the devastating Hamburg attacks led many in the Nazi leadership to wonder whether Germany would be able to find a way out.
The first heavy attack on Hamburg made an extraordinary impression, Speer told interrogators in 1945. Other Nazi higher-ups were also stunned by the bombing of Hamburg. A city with a million inhabitants has been destroyed in a manner unparalleled in history, Goering reported. Propaganda Minister Joseph Goebbels wrote that regime functionaries in Hamburg described a catastrophe the extent of which simply staggers the imagination. Goebbels thought food, shelter, clothing, and evacuation transport all presented nearly impossible problems after the raid. He added that the local Nazi official spoke of some 800,000 homeless people who are wandering up and down the streets not knowing what to do.
To historian William L. Shirer, the greatest damage was to the homes and the morale of the German people. Shirer remembered how lurid reports of Luftwaffe bombing of England had buoyed up German hopes for a quick victory early in the war. Those hopes, naturally, evaporated in an instant. Germanys military leaders could not deny the consequences. Hamburg, coming on top of the disasters on the Soviet front, brought home to many that Germany was heading for doom.
Speer said in 1945: It was I who first verbally reported to the Fuehrer at that time that a continuation of these attacks might bring about a rapid end to the war.
It was not to be. In 1943, the power to capitulate was held by only one personHitler. His flunkies might be terribly shaken, but Hitler was not. He refused to visit any bombed cities despite the pleas of Goebbels and others that he do so.
Beginning of the End
Harris and Bomber Command did not win the war at Hamburg. The Allies couldnt know it at the time, but they faced nearly two more years of hard fighting and tough losses.
The city of Hamburg was attacked several more times right through the end of the war, although there were no more firestorms there. The only other firestorm to destroy a German city came at Dresden in February 1945. (See The Dresden Legend, October 2004, p. 64.)
Still, the destruction of 6,200 heavily urbanized acres of Hamburg was grim enough. Only Berlin, with 6,427 burned-out acres, had more total area leveled, according to Bomber Commands calculations.
Harris had made his point. He turned the tables on Germany itself and Bomber Command shook the foundations of the Reich. What Bomber Command amply demonstrated at Hamburg was that the war could, and would, be won by the Allies, and that Germany would pay dearly. Time was running out on the Reich. As Churchill said, after the Axis forces began retreating from North Africa in November 1942, it was the end of the beginning. Hamburg in July 1943 was the beginning of the end.
In 1945, the city of Hamburg surrendered to British armies with no resistance.
Dates:
The orders for Operation Gomorrah were signed on May 27, 1943. Commencing on the night of July 24, 1943, the bombing continued until August 3.
Commanders & Forces:
Allies
Air Chief Marshal Arthur "Bomber" Harris, Royal Air Force
Major General Ira C. Eaker, US Army Air Force
British: approx. 700+ bombers per raid
Americans: approx. 50-70 bombers per raid
Results of Operation Gomorrah:
Operation Gomorrah destroyed a significant percentage of the city of Hamburg, leaving over 1 million residents homeless and killing 50,000 civilians. In the immediate wake of the raids, over two-thirds of Hamburg's population fled the city. The raids severely shook the Nazi leadership, leading Hitler to be concerned that similar raids on other cities could force Germany out of the war.
Battle Summary:
Conceived by Prime Minister Winston Churchill and Air Chief Marshal Arthur "Bomber" Harris, Operation Gomorrah called for a coordinated, sustained bombing campaign against the German port city of Hamburg. The campaign was the first operation to feature coordinated bombing between the Royal Air Force and the US Army Air Force, with the British bombing by night and the Americans conducting precision strikes by day. On May 27, 1943, Harris signed Bomber Command Order No. 173 authorizing the operation to move forward. The night of July 24 was selected for the first strike.
To aid in the operation's success, RAF Bomber Command decided to debut two new additions to its arsenal as part of Gomorrah. The first of these was the H2S radar scanning system which provided bomber crews with a TV-like image of the ground below. The other was a system known as "Window." The forerunner of modern chaff, Window was bundles of aluminum foil strips carried by each bomber, which, when released, would disrupt German radar. On the night of July 24, 740 RAF bombers descended on Hamburg. Led by H2S equipped Pathfinders, the planes struck their targets and returned home with a loss of only 12 aircraft.
This raid was followed up the next day when 68 American B-17s struck Hamburg's U-boat pens and shipyards. The next day, another American attack destroyed the city's power plant. The high point of the operation came on the night of July 27, when 700+ RAF bombers ignited a firestorm causing 150 mph winds and 1,800° temperatures, leading even the asphalt to burst into flames. Strung out from the previous day's bombing, and with the city's infrastructure demolished, German fire crews were unable to effectively combat the raging inferno. The majority of German casualties occurred as the result of this firestorm.
While the night raids continued for another week until the operation's conclusion on August 3, the American daytime bombings ceased after the first two days due to smoke from the previous night's bombings obscuring their targets. In addition to the civilian casualties, Operation Gomorrah destroyed over 16,000 apartment buildings and reduced ten square miles of the city to rubble. This tremendous damage, coupled with the relatively small loss of aircraft, led Allied commanders to consider Operation Gomorrah a success.
Thoughts on the matter? Did the firebombing of Hamburg go too far as a retaliation by the British or was it a rightful response to the Blitz?
