Bludgeoning with Bombs
Germany, 1944-45
It has been an unhappy fact for the rest of the world that these gullible and warlike people [the Germans] should have developed a powerful industrial and technical organization to support a huge military machine. This machine depends on some 90-odd industrial centers of which perhaps 50 are of major importance. If these centers can be destroyed or seriously damaged it must be obvious that her means to make war will be reduced. And in the process of destroying them the people can be given theirfirst searing lesson, in the heart of their hitherto untouched homeland that crime doesn’t pay. This should reduce their will to fight. If, therefore, we can reduce the means to fight and the will to fight, the tasking of overpowering her is made easier or the time shortened. That, very simply, is the contention of the Air Forces.

As the crews of 311 B-17S approached their target, a smoky black haze arose from the city surrounding it and mingled with dense clouds. Dresden, the medieval capital of Saxony, was in ruins. More than 750 raf Lancasters had dropped 1,471 tons of high explosive bombs and 1,175 tons °f incendiaries on the refugee-filled city the night before, and now the Eighth Air Force would add to that total.1 The thick blanket of clouds across northern Europe had caused the target to change as the B-17S crossed the English Channel. Originally, it had been the vast marshalling yard on the southern bank of the Elbe. By the time crews could see the smoke rising from the city, the target had become a rail intersection in Dresden’s center, west of the main residential area.
Clouds obscured the rail junction, though, and when the lead bombardier signaled “Bombs away!” he was actually over Dresden’s most densely populated district—the same area that the raf had pummeled just hours before. Using radar bombing techniques, the B-17S dropped more than seven hundred tons of bombs, almost half of which were incendiaries. The next day, 211 B-17S attacked Dresden’s marshalling yard, and cloud cover once again prevented accurate bombing. Almost five hundred tons of high explosive bombs fell on the city’s center.2 The series of raids created a firestorm similar in intensity to the one almost two years earlier at Hamburg; between twenty-five thousand and thirty-five thousand German civilians died, and an estimated five hundred thousand lost their homes.3
On the afternoon of 15 February, raf Air Commodore С. M. Grierson conducted a press conference in Paris in which he highlighted the Dresden raids. Grierson stated that bombing population centers caused the Germans difficulty because it forced them to send in trains carrying relief supplies and send out trains carrying homeless civilians, thereby disrupting transportation and contributing “greatly to the break up of the German economic system.” Concerning Dresden, Grierson noted that the city was a communications center that the Germans used to relay men and equipment to the Russian front, and that refugees fleeing the Russians clogged the city. He maintained that the principal reason for the raids was to stop communications rather than to kill refugees.4
Grierson’s comments had an immediate effect on the journalists in attendance. One of them, the ap’s Howard Cowan, wrote on page i in the 18 February edition of the Washington Star: “The Allied Air Commanders have made the long awaited decision to adopt the deliberate terror bombing of great German population centers as a ruthless expedient to hasten Hitler’s doom.” Cowan added that “more raids such as the British and American heavy bombers carried out recently on the residential sections of Berlin, Dresden, Chemnitz, and Cottbus are in store for the Reich, and their avowed purpose will be creating more confusion in the German traffic triangle and sapping German morale.”5 The article created an uproar at Army Air Forces headquarters in Washington dc, and at Coral Gables, Florida, where recently promoted five-star General Hap Arnold was recovering from his fourth heart attack of the war. Arnold demanded an explanation. He cabled General Carl Spaatz, the Commander of the U. S. Strategic Air Forces (usstaf), and told him to “transmit as a matter of urgency the specific text of your present directive to usstaf, together with any further comments in order to clarify in my mind completely the entire present situation as to directives and priorities for strategic bombing.”6
Spaatz was away from his headquarters near London visiting units in the Mediterranean, and his deputy commander, Major General Frederick Anderson, received the Cowan article as well as Arnold’s request from a Colonel Rex Smith, who lamented, “This is certain to have nationwide serious effect on the Air Forces as we have steadfastly preached the gospel of precision bombing against military and industrial targets.”7 Anderson replied to Arnold on 19 February, contending that Cowan’s article was an exaggeration that had slipped past the censors. “We have not, or do not,” he asserted, “intend to change the basic policy which has governed the direction of effort of the United States Strategic Air Forces in Europe from the time they first started operations in this Theater. Our attacks have been in all cases against Military objectives.”8 Colonel Alfred R. Maxwell, usstaf’s Director of Operations, followed with another message written on Spaatz’s behalf: “It has always been my [Spaatz’s] policy that civilian populations are not suitable military objectives.”9 An Army Air Forces spokesman in Washington DC mirrored those replies in a zi February press conference, remarking that Americans stressed precision bombing over “wasteful and ineffective” indiscriminate attacks and adding, “We have never done deliberate terror bombing. . . we are not doing it now… we will not do it.”10
Such statements were half-truths at best. Since May 1943 when Ira Eaker, then the Commander of Eighth Air Force, acknowledged that cloud cover prevented precision bombing, the American bomber force had often resembled raf Bomber Command on days that weather obscured the target area. The distinction between the two bomber forces became especially thin once the Eighth Air Force received radar bombing equipment in autumn 1943 an<-I Eaker informed Arnold of his intention to break the morale of the German public. Spaatz had refused to state such an objective since taking charge of usstaf in January 1944. Yet he consistently bombed Germany using radar whenever the weather was disagreeable, and he possessed many more bombers than had Eaker.
Moreover, the longer the war progressed, the louder the clamor grew to end it, and the closer Spaatz’s targets crept to residential districts in German cities. Both Dresden’s marshalling yard and the rail junction selected for the 14 February attack were less than a mile from the heart of the city’s residential area. Even with the Norden bombsight in excellent weather, bomber crews were certain to hit more than just their aiming point; using radar against a “precision” target in the midst of a city guaranteed many civilian deaths. Indeed, the “last resort” target for the 14 February Dresden mission was: “Any military objective definitely identified as being in Germany and east of the current bomb line.”11 By February 1945 the impetus to end the war quickly provided few limits to the definition of “military objective.”
Spaatz and the Battle for Air Superiority
When Arnold tapped Spaatz in late 1943 to lead usstaf, the new command comprising the heavy bombers of Eighth and Fifteenth Air Forces, both men understood that the paramount need for rapid results might forestall the conduct of an efficient air campaign. Spaatz had to gain daylight air superiority, and do so quickly— Overlord could not occur without it. He possessed a wealth of experience for the task at hand. A fighter pilot in World War I, Spaatz arrived at the front three weeks before the armistice and shot down three German aircraft, earning him the Distinguished Service Cross. During the interwar years, he commanded both a bomb group and a bomb wing, plus he helped set a flight endurance record of 150 hours (along with Ira Eaker and three other crewmen) aboard the Question Mark in 1929. He had been Arnold’s choice to command Eighth Air Force when it began the daylight assault on Hitler’s Europe, and competently led the Northwest African Air Force as it supported the American ground advance from North Africa to Italy.
Moreover, Tooey Spaatz was a man Arnold could trust, and trust implicitly, to get him the desired results. The two had established an enduring friendship through many assignments together, and a 1920 incident in San Francisco typified the depth of that connection—after Colonel Arnold, who served as air officer for the Army’s Ninth Corps Area, reverted to his prewar rank of captain, Major Spaatz, who had been Arnold’s executive officer, requested a transfer rather than take command of a unit that he thought rightfully belonged to Arnold.12 Modest in appearance with a graying mustache, loyal and selfless, Spaatz commanded respect from all who knew him. Dwight Eisenhower rated him, along with Omar Bradley, as the two American generals who contributed the most in the war against Germany, and Bradley ranked Spaatz second, after Eisenhower’s chief of staff, Bedell Smith.15
Eaker, asked to rank Army Air Forces officers in November 1944 in terms of their merit for postwar leadership, listed Spaatz second behind Arnold.14
Arnold presented Spaatz with usstaf in January 1944 to achieve daylight air superiority over Europe and facilitate the Normandy invasion—and, if all went well, to score a knockout blow against German industry. Arnold had long believed that a single air commander was essential for the maximum efficiency of a heavy bomber force and to prevent ground commanders from taking air elements piecemeal to pursue their own objectives.15 With Spaatz he had the desired unity of command and the prospect that air power could make the decisive contribution to ending the European war.
Much like Eaker before him, Spaatz heard the steady ticking of a clock as he set out to snatch control of the European sky from the Luftwaffe. He would have preferred to have set his own timetable for destroying Germany’s capability and will to fight, and viewed the invasion “as a necessary temporary diversion of the strategic air forces, not a primary objective of strategic air war.”16 Indeed, when he heard that the Combined Chiefs of Staff had selected a date for Overlord, he reportedly said, “This means the death of the strategic air war.”17 Spaatz would support the invasion with all the force that he possessed, but to him, the primary reason for achieving air superiority was to enhance the bomber offensive’s prospects for independent success.
Compared to Eaker, Spaatz had a vast array of force at his command; American production had finally begun to catch up to wartime requirements. New crews began to arrive in theater as well. By the end of December 1943 Eighth Air Force possessed twenty-six heavy bomber groups compared to eleven the previous May—so many aircraft and crews that Lieutenant General James “Jimmy” Doolittle, the new Eighth Air Force Commander, could regularly send out missions with a mix of seven hundred
B-17S and B-24S. Many of Doolittle’s B-17S were new “G” models, which had a combat radius of seven hundred miles—nearly three hundred miles more than most of Eaker’s B-17S—plus they could carry two thousand more pounds of bombs. The “G” model also possessed a chin turret under its Plexiglas nose to ward off head- on fighter attacks, a favorite tactic of the Luftwaffe pilots. The в-24 had received a nose-turret as well, though it was manned instead of remotely operated as in the в-17 and made the bomber a bit wobbly in flight, yet the “Liberator” could still carry the same seven-thousand-pound bomb load as the “G” model “Flying Fortress.”18 B-24S comprised two-thirds of the heavy bombers in Fifteenth Air Force, headquartered in Foggia, Italy, and capable of attacking targets in southern Germany, Austria, and the Balkans. By February 1944, the Fifteenth possessed twelve groups of “heavies.”19
An increase in fighter strength for Eighth and Fifteenth Air Forces matched the sizable gains in heavy bombers—and Army Air Forces engineers finally began to perfect 75- and 108-gallon drop tanks that allowed fighter escort for a distance of six hundred miles, enough to reach Berlin. The p-47 “Thunderbolt” and p-51 “Mustang” were the key escort fighters; both could fly in excess of 430 mph above 25,000 feet, and the P-47 could approach 550 in a dive. At the beginning of 1944 Eighth Air Force possessed eleven fighter groups containing between seventy-five and ninety – six aircraft each, and by February Fifteenth Air Force would have four fighter groups of its own. In addition, Spaatz and Doolittle decided that Eighth Air Force fighter pilots, who had thus far flown escort by staying close to the bombers that they defended, could now roam freely to seek out Luftwaffe fighters. Eighth Air Force fighter pilots also received the same amount of credit for destroying enemy aircraft on the ground as they did in aerial combat to encourage the strafing of airfields. Bomber crews were initially dismayed by these policies, but the new directives soon paid dividends over Germany.20
Spaatz realized that “cutting loose” his fighters would produce increased combat—and hence increased losses—for his fighter force. Given the situation that he faced, he felt that he had little choice. He had three months to wrestle control of the air from the Luftwaffe; in April, General Eisenhower would take charge of usstaf (and kaf Bomber Command) for invasion support. Yet Spaatz also knew that he had an abundance of numbers and a steady stream of replacements, while Ultra intelligence intercepts told him that the German fighter force had suffered severely during Eaker’s fall offensive—so much that Luftwaffe commanders had reduced recuperation times for wounded pilots, and even ordered test and transport pilots to fly against American bombers.21
In late January, Spaatz wrote Arnold that he could not simply wait for decent weather to bomb German aircraft factories— destroying them would not suffice to gain daylight air superiority in the time allotted. Thus, Spaatz would also bomb German airfields, and he would further attack “objectives which force German fighters into combat action within range of our fighters.” In short, he would wage attrition warfare, and use his bombers as bait. “Losses will be heavy,” he stated, “but we must be prepared to accept them.”22 He was confident not just that he could sustain the losses, but also that the magnitude of destruction inflicted on the Luftwaffe would produce air superiority in the shortest amount of time. Spaatz even acknowledged a willingness to risk bombers without fighter escort if such attacks yielded corresponding damage to the Luftwaffe. “Under peculiar weather conditions when all of Germany is fog-bound,” he told Arnold, “raids might be made well beyond fighter cover on area targets, such as Berlin, to force the German fighters into the air under conditions which will result in heavy operational losses to their fighters.”23
Until the weather cleared, Spaatz would continue radar bombing, much like Eaker in late 1943. American engineers at mit had perfected their own version of the British H2S device, and the American model, dubbed H2X, employed a shorter microwave length that resulted in a sharper radar picture of the ground. But H2X did not appreciably increase bombing accuracy, and the Army Air Forces official historians glumly noted that with radar “the aiming point became a highly theoretical term.”24
Arnold knew that radar bombing was far from precise, but he did not want his air commanders to convey that impression publicly. He directed Spaatz to avoid the phrase “blind bombing” when referring to raids with H2X, and Spaatz agreed to label such attacks “overcast bombing technique,” “bombing through the overcast,” or “bombing with navigational devices over clouds extending up to 20,000 feet.”25 Regardless of the terminology used, Eighth Air Force bombers mounted six weeks of radar raids, including a mission by more than eight hundred B-17S and B-24S against Frankfurt on 29 January, which mirrored raf Bomber Command’s area attacks in terms of methods used and damage inflicted. Remarked the aaf historians: “It seemed better to bomb low-priority targets frequently, even with less than precision accuracy, than not to bomb at all.”26
While Spaatz likely agreed with that assessment, he could not wait indefinitely to achieve significant results. On 8 February he directed that “Operation Argument,” the anticipated assault against the German aircraft industry by the Eighth and Fifteenth Air Forces, would conclude by 1 March 1944. Primary targets would consist of airframe and final assembly plants for single – and dual-engine fighters as well as ball bearing production facilities, which members of the Committee of Operations Analysts (coa) and usstaf planners alike deemed essential to aircraft construction.27 Those targets all demanded “precision” bombing, and to attack them successfully Spaatz needed a week-long stretch of decent weather. Thick clouds had canceled Argument on numerous occasions, but Spaatz could no longer wait for ideal conditions and accepted that poor weather might lead to losses exceeding two hundred bombers for a single mission.28
On 19 February usstaf’s weather officers predicted a period of clear skies across Europe, in contrast to the forecast made by weather officers at Eighth Air Force. Major General Frederick Anderson, Spaatz’s deputy commander who had led VIII Bomber Command for Eaker, urged Spaatz to begin Argument. Spaatz gave the order and risked that clouds and icing might ground many of his escort fighters. His fears proved illusory. The next day, sixteen combat wings of heavy bombers—more than 1,000 aircraft— supported by seventeen groups of escort fighters took off for targets in southern Germany, usstaf’s forecasters proved correct, and 941 heavy bombers attacked fighter assembly plants in the vicinity of Leipzig and Brunswick. German defenses claimed 21 bombers, but the bombing results were good.29
The 20 February mission marked the beginning of a six-day series of attacks dubbed “Big Week.” Not only did Eighth and Fifteenth Air Forces jointly participate in many of the attacks, but the raf contributed as well by pounding many of the target cities the night before American bombers attacked specific installations in them. The Luftwaffe fought back fiercely and losses were heavy. On 22 February the Eighth lost forty-one bombers and the Fifteenth lost nineteen; on 24 February the Eighth lost forty-nine bombers and the Fifteenth lost seventeen; and on 25 February, when both Air Forces jointly attacked the Messerschmitt plants at Regensburg, the Eighth lost thirty-one bombers and the Fifteenth lost thirty-two, which was 19 percent of the Fifteenth’s attacking force. All told, Big Week cost the Eighth Air Force alone three hundred aircraft, most of which were bombers, and 2,500 airmen killed, wounded, or taken prisoner.30 Yet on Spaatz’s balance sheet, the advantage was decisively his—in February the Germans lost 33 percent of their single-engine fighters and 18 percent of their fighter pilots, many of whom had shot down more than one hundred aircraft.31 Improved P-47S with water-injection engines were responsible for most of the damage done to the Luftwaffe; only two groups of Mustangs participated in the air battles.32 The Thunderbolts tipped the balance for control of the skies in favor of the Americans.
Besides inflicting substantial damage in the air, Big Week also hurt the German aircraft industry. Radar bombing occurred on few missions; crews conducted most attacks with the Norden bomb – sight.33 B-17S and B-24S dropped more than ten thousand tons of bombs during the six-day span—more tonnage than the Eighth Air Force had dropped on all targets for all of 1943.34 The attacks completely wrecked the Regensburg complex and damaged other facilities as well, but analysts’ claims that the attacks had reduced production to 650 aircraft a month were wishful thinking. In actuality, the large amount of slack in the German aircraft industry enabled the monthly production rate to increase despite the raids; many factories with only one shift of workers changed to twenty-four-hour operations.35 Still, Big Week stymied German production plans. Nazi economic leaders had calculated that they could produce 80,000 aircraft a year by 1945, Уег they reached only 36,000 in 1944.36 Big Week was a key reason that they could not produce more.
Buoyed by Big Week’s success, Spaatz turned his attention to the target that American airmen had most wanted to bomb since their first raid over Hitler’s Europe—Berlin. The first raid against the German capital was a feeble one, when 29 B-17S failed to get a weather recall message on 4 March and pressed on to their target; they survived because three groups of p-5 is stayed with them.
Two days later, Spaatz unleashed 730 heavy bombers and 800 escorting fighters in an aerial stream sixty miles long. The Luftwaffe defended tenaciously, and 75 bombers were shot down, crashed, or written off. Yet the statistic that mattered most to Spaatz was enemy losses, and his fighter pilots claimed 82 German aircraft downed for a cost of 14 American fighters.37
On 8 March the onslaught continued. Spaatz sent 600 bombers and 900 fighters against Berlin, losing 13 bombers and 17 fighters. Three hundred bombers returned the next day, bombing through the clouds with H2X. Nine heavies fell to flak—but none were lost to Luftwaffe fighters, which did not oppose the attack. On 22 March 650 bombers returned to Berlin, and flak claimed all 12 that fell.38 For the month, Luftwaffe fighter units wrote off 56 percent of their single-engine fighters, while crew losses reached almost 22 percent of the pilots present for duty at the beginning of March.39 American bomber crews suffered as well; Spaatz lost 345 heavy bombers in March alone.40 Yet, in blunt terms, he felt he could afford the losses; he knew the Germans could not. At the end of the month, with the Luftwaffe reeling, Arnold raised the tour length for bomber crews from 25 to 30 missions. Spaatz had given him daylight air superiority.
Spaatz had achieved what Eaker could not because Spaatz possessed an abundance of resources that allowed him to conduct an air campaign based on attrition.41 Eaker had counted on the Luftwaffe’s aerial losses to spur his quest for air superiority as well, but anxiety about the survival of his bomber force prevented persistent attacks deep into Germany. Neither Eaker nor Spaatz completely abandoned their progressive belief that the destruction of key targets like aircraft factories and ball bearing plants would produce rapid results; their concern was whether the results would occur rapidly enough. As the countdown toward Overlord continued, a negative answer appeared likely. Spaatz chose to forego the progressive goal of “cheapness” to obtain the higher priority objective of speed, and, in the end, was successful. Yet the cost was enormous. Eaker’s painstaking commitment of a weak bomber force that lacked escort fighters, and Spaatz’s ruthless use of the strength that he possessed, combined to make a staggering 77 percent of all American airmen who flew against the Third Reich before D-Day casualties.42
Eaker and Spaatz had accurately surmised the importance of the German aircraft industry to Hitler’s war machine. The Luftwaffe was not going to risk losing its production centers without a fight—which was exactly what Spaatz hoped in early 1944. Between January and the end of April, the Germans had 1,684 pilots killed, and Ultra intercepts made Spaatz aware of the loss.45 Eaker, who now “owned” Fifteenth Air Force as a part of his Mediterranean Allied Air Forces (Spaatz, as usstaf Commander, directed the heavy bombers of the Fifteenth and coordinated with Eaker on all missions for that force), gained bittersweet satisfaction in knowing that the plan he had set in motion finally bore fruit. Without the damage that Eaker’s Eighth Air Force had inflicted on the Luftwaffe, Spaatz could never have gained air superiority in the time allotted.
In one sense, the achievement of air superiority that enabled Overlord fulfilled the progressive goal of inexpensive results by guaranteeing that fewer Allied soldiers would die in the invasion than if the Germans had retained control of the air. Whether the Allies would have attempted a cross-Channel assault lacking control of the air remains doubtful, though, especially in light of the disastrous Dieppe raid in August 1942.44 American air leaders hoped that the bomber offensive might eliminate the need for an invasion by wrecking German capability and will to fight once the air campaign gained control of the sky. Army Air Forces planners designed both awpd-i and AWPD-42 with that goal in mind, and that objective still resonated at the Casablanca Conference in January 1943, when the Combined Chiefs of Staff defined the purpose of the Combined Bomber Offensive as destroying German military, industrial, and economic capability, and the morale of the German people “to a point where their capacity for armed resistance is fatally weakened.”45
By the time of the Trident Conference four months later, the Combined Chiefs defined “fatally weakened” as “so weakened as to permit initiation of the final combined operations on the Continent.”46 Arnold, Eaker, and Spaatz would have defined it differently if given the choice. Instead, they had to temper their expectations for independent success and hope that air power could still play a decisive role in Overlord’s aftermath. Arnold in particular would view the failure of the bomber offensive to forestall the invasion of France as impetus to make sure that a similar air campaign in the Pacific did not lead to similar results.
