PREFACE
The air war in the skies over Europe during World War II was extremely complex and costly, and the Germans proved to be a formidable enemy. The Royal Air Force bombed German targets at night and the U.S. Army Air Forces took the fight to Germany during daylight hours. All of the British Commonwealth countries provided manpower to fight the Axis, and aircrews from the Soviet Union also battled the Germans.
The Army Air Forces had to fly four mission profiles in order to defeat the Germans: air superiority, ground attack/tactical bombardment, close-air support, and strategic bombing. Each mission profile dovetailed with the others. Strategic bombing of war production, petroleum, and transportation targets needed air superiority in order to succeed. Air superiority could not be achieved until the production of enemy aircraft and petroleum products was curtailed by strategic bombing. With air superiority, enemy aircraft could be destroyed on the ground before they would have the opportunity to attack the strategic bomber formations or Allied troops invading the continent. And Allied troops liberating Europe could not receive close-air support from ground attack aircraft and tactical bombers until the skies were relatively safe from marauding enemy fighters.
None of these objectives could be achieved without the might of American and Allied war production on the home front. Planes for the Allied war effort were built in Australia, Canada, England, and the United States. America’s aircraft production during World War II amounted to 295,959 aircraft, of which 200,443 were combat types. The Army Air Forces received 99,487 combat aircraft between July 1940 and August 1945. During this period, the Eighth Air Force operated B-17s and B-24s in the strategic bomber role; these were escorted first by Royal Air Force Spitfires, and later by Eighth Fighter Command P-38s, P-47s, and P-51s.
THE GREAT DEBATE
Some may say that the sacrifices of the B-17 Flying Fortress crews are greatly represented on these pages in comparison to those of the B-24 Liberator crews. While the sacrifices of all Eighth Air Force combatants are chronicled on these pages, there were two divisions (a division was typically four combat wings consisting of three bomb groups each) of B-17s versus only one of B-24s assigned to the Eighth Air Force. Thus, it can be interpreted that the pool of European Theater heavy bomber images was inherently slanted at a ratio of two B-17 photos for every B-24 picture. The total was subsequently reduced by the Army Air Forces as a result of what it chose to publish during the war and the images it chose to archive. A review of the Army Air Force/Air Force Collection images at the National Archives turns up a far greater number of B-17 photographs than those of B-24s. It’s nothing personal, just the way history was recorded and preserved.
Bloody Skies: U.S. Eighth Air Force Battle Damage in World War II is a photographic chronicle of the often tragic results of aerial combat, as fought by the “Mighty Eighth.” This volume is intended as a tribute to those who served and those who paid the ultimate price in the air war over Europe. And let us not forget the families who suffered during the long absences when loved ones were away at war, some never to return.

When most people think about the Army Air Forces and the air war in Europe, they picture the Eighth Air Force of 1945—an air force that ranged over Fortress Europe, destroying industrial and military targets at will on a daily basis. The Eighth Air Force of 1945 was triumphant; they were the victors, owners of air superiority over the nations that had once been subjugated by the armies of Adolf Hitler’s Third Reich. But the Eighth Air Force of 1945 was very far removed from the dark days of December 1941 when America entered the war. The first half of 1942 was no better for America as the shock of war set in and the U.S. military was thrust from a stance of guarded neutrality into total war.
In the early months of 1942, England was absorbing the brunt of Hitler’s thirst for conquest as the Nazi war machine had conquered most of Europe. Striking back at the Nazis, the British found the cost of daylight bomber raids to be extremely high. To hold down losses, the Royal Air Force elected to bomb cities and industrial targets in Germany at night.
Having occupied a number of European nations at little cost, Adolf Hitler turned the victorious Nazi war machine to the east on June 28, 1942. Summer weather enabled the German army to roll up to the gates of Stalingrad with relative ease. However, the Germans were unprepared for Russia’s harsh winter weather and the vicious counterattacks by Soviet troops.
The early and middle parts of 1942 were spent building an air force in England to take the fight to the Germans. The most expeditious way to get large numbers of four-engine bombers and twin-engine fighters across the Atlantic Ocean was to ferry them. Aircraft en route to England left North America at Goose Bay, Newfoundland, Canada, flew 780 miles to Greenland, then 775 miles to Keflavik, Iceland. It then traveled another 845 miles to Prestwick, Scotland, and on to bases in England. Not all planes completed the crossing, including B-17F 42-3128, which crashed near Patterson Field outside Grindavik, Iceland, on April 17, 1943. The pilot, Thomas F. Witt, went on to serve with the 306th Bomb Group and became commander of the 367th Bomb Group at Thurleigh, England. USAAF
While war in Europe raged, the United States began forming the Eighth Air Force in England. Bombers and fighters were flown from factories and training bases around the United States, through Canada, Greenland, Iceland, and Scotland, eventually reaching the rolling farm country that is East Anglia, north and east of London. The first Army Air Force B-17 landed in England on July 2, 1942. Two days later, six American bomber crews flew Douglas A-20s (borrowed from No. 226 Squadron, RAF) in formation with six Royal Air Force Bostons to bomb airfields in Holland. Aside from the propaganda benefit to those back home in America, the raid had no strategic value; however, it demonstrated that the United States had arrived in England and was ready to join the war.
America’s strategic bombing force was built around the doctrine that huge bomber formations would be able to protect themselves from fighter attacks with their own defensive guns. Before World War II, the majority of fighters and bombers were equipped with 0.30-cal. machine guns. As aviation technology evolved, however, it became apparent that the 0.30-cal. gun could not effectively defend a bomber from attack or enable a fighter to shoot-down the new, all-metal aircraft being introduced by air forces around the world.
B-17s and B-24s were equipped with 12 of the more powerful 0.50-cal. machine guns, each capable of firing 750 rounds per minute. The Browning–designed M-2 0.50-cal. machine gun fired a 1.71-ounce projectile with a muzzle velocity of 2,750 feet per second (1,875 miles per hour), giving the bullet a maximum range of 4.1 miles (7,200 yards) in still air. Army Air Force B-17 or B-24 gunners defending their bombers from a turret or the open waist gun positions were taught not to fire at enemy aircraft farther than 600 yards from their bombers. The slipstream of the flying bomber coupled with the combined closing speeds of both the defender and the attacker sharply reduced the 0.50-cal. machine gun’s effective range and accuracy.
When bombing a target with a formation of Flying Fortresses or Liberators, Army Air Force planners had to consider the security of the bomber force (essentially how vulnerable were the bombers to enemy fighter attacks); visibility; flexibility (how quickly could an alternate target be attacked should the primary target be weathered-in); the formation’s bomb pattern (how to position the formation’s aircraft in order to cause the most destruction); and ease of flying (should B-17 and B-24 formations be mixed). They also had to evaluate how the fighters should best cover the bombers and if the attacking force could be commanded from within the formation. It took the Eighth Air Force more than a year of operations, experimenting with different formation configurations, to come to the realization that no matter how they stacked the bombers, they would never be able to defend the miles-long bomber stream from German fighter attacks.
The original daylight precision bombing concept proposed that firepower from each of the heavily armed bombers could maintain the security of the formation, enabling the aircraft to defend themselves to and from the target. Although many different formation configurations were tried, American bombers could not defend themselves from the lethality of Germany’s fighters. USAAF
Although a number of fighter aircraft tried to escort the bombers to and from targets, none had the range to shepherd them deep inside Germany. It was not until the arrival of the Rolls-Royce Merlin engine–powered North American P-51 Mustang and a change in tactics that bomber formations could strike at German industry anywhere on the European continent. Here a gaggle of P-51 Mustangs from the 352nd Fighter Group (stationed at Bodney Airfield, England) escorts B-24 Liberator bombers from the 458th Bomb Group (based at Horsham St. Faith, England) late in the war. USAAF
While the Army Air Forces was learning its craft, the Luftwaffe was learning, too. The Germans were adapting their tactics to combat the bomber streams, improving armament in their aircraft to enable attacks from outside the 0.50-cal. machine gun’s range. In addition, they were developing new aircraft, such as improved, higher-altitude versions of the Fw 190, rocket-propelled point-defense fighters (Me 163), and jet fighters (Me 262), all while strengthening their antiaircraft defenses in an effort to tip the balance of aerial combat into their favor.
U.S. Army Air Force bombers began missions against U-boat pens and the port infrastructure that supported German submarines at Le Havre, France, and Rotterdam, the Netherlands, in September 1942. These targets were outside the range of escorting Spitfires and required the bomber streams to fly tighter formations for mutual fire support from the formation’s guns. Flying in “V” formations of three aircraft, known as elements, eighteen aircraft groups were comprised of two boxes of three elements each. The second aircraft box was positioned 500 feet above and in echelon to the right or left, depending upon the angle of the sun.
As the formations grew larger, the various aircraft boxes were positioned progressively higher, in 500-foot increments, above the lead element. Thus, in a thirty-six bomber formation, the lead element (twelve aircraft) was at a set altitude, for example 20,000 feet, and the trailing elements of twelve aircraft each would be at 20,500 feet and echeloned to the right, with the third element at 21,000 feet and echeloned to the left.
This positioning continued as the formations expanded; essentially, boxes of aircraft were tacked onto the back of the bomber stream as the numbers increased. The Dec. 20, 1942, raid on the Luftwaffe’s air depot at Romilly-sur-Seine in north-central France was the first mission where the Eighth Air Force dispatched more than a hundred bombers (eighty B-17s and twenty-one B-24s).
The German Messerschmitt Bf 109 fighter savaged Eighth Air Force bomber formations as they entered the airspace over Nazi-occupied Europe. The fighter was highly maneuverable, had an outstanding rate of climb, and was equipped with four 7.92mm machine guns and a 20mm cannon that fired through the propeller hub (Bf 109E). More than 33,900 Bf 109s of all models were built between 1936 and 1945. USAAF
The Focke-Wulf Fw 190 single-seat fighter entered the fray in August 1941. By 1944, there had been a number of improvements in armament as well as high-altitude performance. More than twenty thousand of this type were built, and they joined the Bf 109 in attacking Allied bomber formations throughout the war. USAAF
The following year, the Eighth Air Force was improving its bomber aircraft to combat the changes in Luftwaffe tactics. Various armament configurations were tested in combat, and many of those experiments became standard equipment on B-17G and B-24J and later bombers.
As 1943 ended, the Eighth Air Force was making extensive use of radar bombing of targets obscured by cloud cover. With only a limited number of pathfinder-equipped aircraft available to lead the bombers, the formations had to be compressed. The groups were now made up of a lead element, a high element, a low element, and a low-low element, which enabled more of the bombers’ guns to be trained outside of the formation. In addition, the distance between each group was reduced from 6 to 4 miles, putting more bombers over the target more quickly.
In February 1945, the bomber formation was reconfigured into a twenty-seven aircraft group (thirty-six bombers when a low-low squadron was added). Each squadron was now nine planes, and three nine-plane squadrons made up each group. Each group of twenty-seven aircraft was separated by two minutes flying time, further reducing the amount of time spent over the target and flying through the German army’s murderous flak. It should be noted that the B-24s of the Second Air Division flew the same formation, although the high or low squadron was often flown to one side of the lead element. This reduced the workload on the pilots and provided an increased safety margin when flying formation because of the Liberator’s restricted visibility.
ESCORT FIGHTERS AND “THE ULTIMATE PURSUIT OF THE ENEMY”
From its inception, the Eighth Air Force’s fighters were used to protect the bomber formations. The first escort fighters were reverse lend-leased Supermarine Spitfires, which were used until substantial numbers of P-38s and P-47s came on strength. The first P-47 escort mission was on May 4, 1943, when 117 Thunderbolts from the 4th, 56th, and 78th Fighter Groups escorted 79 B-17s to Antwerp, Belgium. The Thunderbolts flew “umbrella” cover—the fighters maintained top cover. The Luftwaffe adjusted its tactics and instead of diving down through the umbrella cover of P-47s, its pilots began horizontal attacks, hitting the bomber formations from the sides or head-on from the same altitude.
At this stage of the war (summer and fall of 1943), the P-47s could only stay with the bombers for twenty to thirty minutes. Thunderbolts would fly from their home bases and rendezvous with the bombers prior to reaching the target. The fighters would escort the bombers over the target and stay with them for part of the return flight, but once the escorts were headed for home German fighters would maul the B-17s and B-24s. It took until October 1943, when 108-gallon drop tanks became available, before the P-47s could escort the bombers up to a distance of 375 miles from base.
In addition to fighters, Allied bombers had to contend with dozens of antiaircraft artillery (AAA) or flak (shortened version of Flugzeugabwehrkanone, aircraft defense cannon) guns positioned around high-value targets. These maps illustrate the size and positioning of flak batteries in September 1943 and February 1945. Note that the increase in flak batteries corresponds to the industrial centers along the Rhine and Ruhr River valleys as well as those areas around Cologne and Düsseldorf, and that other areas, such as Magdeburg and Munich, went from very little flak coverage to heavily defended targets. USAAF
Royal Air Force (RAF) Supermarine Spitfires escorted many of the Eighth Air Force’s early bombing raids against targets on the European continent. Eighth Air Force fighter groups adopted lessons learned by the RAF and modified them as new aircraft were introduced to the theater. The Spitfire was an outstanding point-defense fighter but its range was extremely limited, preventing its widespread use as an escort fighter. USAAF
New 108-gallon drop tanks began arriving in England in February 1944. When equipped with a pair of 108-gallon tanks, the twin-engine Lockheed P-38 Lightning could escort bombers to a point approximately 585 miles from home base. This enabled Lightnings to escort bombers to Berlin and back. USAAF
The Republic P-47 Thunderbolt was a robust fighter that could absorb a tremendous amount of punishment, and its eight 0.50-cal. machine guns could annihilate anything that got in its way. Until the introduction of 108-gallon drop tanks, Thunderbolts could not escort bombers much farther than the Dutch-German border. The use of 108-gallon drop tanks took Thunderbolts to targets as far as Stuttgart, but short of the synthetic oil factories in Magdeburg, Germany. USAAF
North American Aviation P-51 Mustangs powered by the 12-cylinder, 1,490-horsepower Rolls-Royce V-1650 engine were the ultimate air superiority fighter of World War II. Produced in large numbers (15,586 during the war), the aircraft was extremely fast and had an 850-mile escort range. This four-plane element shows three bubble canopy P-51D model Mustangs and one earlier, high-back P-51B (serial number 42-106811) of the 375th Fighter Squadron, 361st Fighter Group, which was based first at Bottisham (Nov. 30, 1943 to Sept. 26, 1944) and later at Little Walden, England (to November 1945). The 361st Fighter Group claimed 226 aerial victories and 105 aircraft destroyed on the ground, with a loss of 81 of its own aircraft. USAAF
In January 1944, Allied escort fighters were allowed to change their tactics. No longer were the fighters required to fly umbrella coverage. The “Ultimate Pursuit of the Enemy” doctrine enabled escort fighters to go after the enemy “until it was destroyed in the air or on the ground.” Simultaneous to this change in Allied tactics, new North American P-51 Mustangs were coming on line. On May 29, 1944, Mustangs escorted the bomber formation to Posen, Poland, and back—a distance of more than 1,400 miles. The addition of the Mustang ensured that Eighth Air Force bombers would never go unprotected again. That did not mean bomber losses had stopped and the Luftwaffe was defeated, but it marked a turning point in the air war over Europe.
TARGET SELECTION
The Eighth Air Force’s target selection fell into four distinct categories that were attacked in chronological order. These target types were determined by the combined chiefs of staff (American Joint Chiefs of Staff and British Chiefs of Staff Committee) on Jan. 21, 1943, and known as the Combined Bomber Offensive (CBO). First, bombers attacked the Nazi submarine bases, construction facilities, and surrounding port infrastructures. Albeit heavily defended, these coastal targets were within range of the fledgling Eighth Air Force and gave the bomber force a series of targets to test its tactical theory under combat conditions.
Beginning in June 1943, the second offensive was opened, with a focus on Luftwaffe infrastructure targets ranging from aircraft assembly plants to ball bearing production to the destruction of fighters in the air and on the ground. The third campaign was the destruction of Germany’s oil industry. Once production at Ploesti, Romania, was crippled by the Fifteenth Air Force, the Eighth Air Force could concentrate on reducing Germany’s oil production to a trickle.
The fourth series of targets attacked was the German Army’s transportation infrastructure—roads, rail lines and marshaling yards, bridges, etc. Destruction of these targets impacted the German Army’s ability to wage war and supported Allied troops as they fought their way across Nazi-occupied Europe to victory.
THE AIR WAR’S HIGH COST
During the air war in Europe, more than 350,000 men served with the Eighth Air Force, of which 26,000 were killed in action, 21,000 were wounded, and an additional 28,000 became prisoners of war.
In terms of B-17 and B-24 heavy bombers, 40 bomb groups (a group was typically four squadrons comprised of 72 aircraft, 720 flying crewmen, and 1,500 other personnel) flew 10,631 missions with combat losses of 4,145 aircraft (each with a complement on average of 10 men). When training and other losses are included, the number climbs to 10,561 aircraft destroyed: 4,754 B-17s, 2,112 B-24s, 451 P-38s, 1,043 P-47s, and 2,201 P-51s.
