Even as these operations were going on, the most important part of the drama was taking place neither in the Baltic nor in the Ukraine but with Army Group Center north of the Pripet Marshes in Belorussia. The armored forces, forming the spearheads of the army group, were put on its wings: 3d Panzer Group (Gen Hermann Hoth) on the left and 2d Panzer Group (Gen Heinz Guderian) on the right. Setting out from Suwalki and Brest Litovsk, respectively-the distance separating them was about 200 miles-these spearheads were to converge on Minsk, some 250 miles inside Soviet territory, in order to form a gigantic pocket. Between the two armored spearheads marched the infantry armies-Ninth Army to the north and Fourth Army to the south. This well-thought-out plan, which gave the German forces shorter distances to cover and enabled them to participate in the campaign by sealing off the pocket formed by the armored spearheads, was designed to allow them to form a second and smaller pocket inside the larger one by meeting at a point on the Bialystok-Minsk road some 100 miles to the east of their starting positions. As usual in maneuver warfare, everything depended on speed and boldness in finding the weak spot and then, having burst through it, striking deep into the enemy's rear. As usual, this could only be achieved by presenting to the enemy long, open flanks that the Luftwaffe had the task of holding and protecting.

 

The starting positions of Guderian's tanks were on the river Bug. As usual, when there was a river to be crossed, the effect was to divert the Luftwaffe units on the spot (Fliegerkorps II) from deep strikes to close support, especially since the crossing sites could be dominated by the guns in the ancient fortress of Brest Litovsk. Fliegerkorps II was accordingly directed to this task even before it could achieve full air superiority; its "rolling attacks" (rollende Einsatz), a kind of operation already familiar from the Battle of the Meuse in 1940, afforded Guderian's rear echelons a safe passage until the fortress finally surrendered. Next, on 23 June units of Luftflotte 2 were instrumental in beating back a furious Soviet counteroffensive at Grodno. It was only after these operations were over that the weight of the attack could be shifted farther to the east. It now fell on the railroads leading into the area of the prospective pocket (interdiction) and also on the roads leading out of them through the Belorussian forest.

 

Even at this early point in the campaign, growing distances were already creating a situation where the long-range reconnaissance and bomber units could not be brought up fast enough for the latter to attack targets identified by the former. With the results of photoreconnaissance often many hours out of date, it became necessary to resort to armed reconnaissance by having the bombers act in both roles at once and attack targets of opportunity, a method that proved wasteful in terms of the time that the units could spend on mission. Acting in this way, Fliegerkorps II was able to obstruct but not entirely prevent the attempts by forces of the Soviet West Front (Gen D. G. Pavlov) to retreat and break out of the pocket; also, since it could not be everywhere at once, it was unable to intervene against the sorties flown by the Red Air Force against the German cavalry division forming the extreme right flank of Army Group Center. Further north, Fliegerkorps VIII was instrumental in beating off a Soviet counterattack launched against Hoth's flank on 24-25 June in the Kuznica-Odel'sk- Grodno-Dembrovo area. Since roads in this area were few and far between, it also airlifted supplies to the rapidly advanced 3d Panzer Group. By means of all these operations, the Luftwaffe contributed substantially to the closing of the pocket at Minsk, the first great German victory in this new campaign.

 

The Battle of Minsk was concluded on 3 July, when the Soviet forces inside the pocket formally surrendered, although it was another five days before resistance came to an end and 290,000 Russian prisoners had fallen into German hands. Meanwhile, the arrival of the infantry had enabled the armor to be disengaged and resupplied. On 9 July, Guderian and Hoth were off again. This time the goal was to close the jaws at Smolensk, 400 miles from the starting positions, thus building another one of those gigantic pockets that were the specialty of the blitzkrieg. The Luftwaffe's principal task was to prevent the Red Air Force from disrupting German preparations for the crossing of the Dnieper, which it did most effectively but not without causing some friendly casualties. On 23 July the pincers met and trapped a mass of Russians. As one might expect from the vast distances, however, the pincers were at first rather thin. The German infantry divisions, though marching hard, had been left far behind by the panzers. Consequently, it again fell to Luftflotte 2 to do its best to hold the pocket until they could arrive. It did so with only partial success; unlike the French in the previous year, the Russians for the most part did not surrender simply because the map showed that their units had been cut off. Using the wooded terrain to hide during the day, many of them were able to break out at night. Field Marshal Albert Kesselring of Luftflotte 2 later estimated that 100,000 Soviet troops had made good their escape in this way, albeit at the cost of leaving their heavy equipment behind and watching their large units disintegrate.

 

Although it was not until 5 August that the pocket west of Smolensk could be regarded as properly closed-and even then gaps remained Fliegerkorps VIII had already been taken away from Luftlotte 2. By Hitler's orders, it joined Fliegerkorps I in its attack towards Leningrad. The remaining formation, Fliegerkorps II, now found its forces strung out thinly across the hundreds of miles forming the front of Army Group Center and attempting to protect its flanks. It had to assist in sealing off the pocket, but at the same time it had to beat off a series of determined Soviet counterattacks against the exposed Yelnya salient across the Dnieper (occupied by Guderian's troops). To add to its trouble, it was called upon to operate far in the south, using Stukas to strike at Soviet armored boats that appeared unexpectedly on the northern edges of the Pripet Marshes and inflicted stinging losses on the German cavalry division there. By this time, the Red Air Force had found its bearings to the extent that it was able to join in the army's attacks on the Yelnya salient. Unable to be everywhere at once, the fighters of Fliegerkorps II were often too late to interfere. Attempting to pursue the low-flying, heavily armored Soviet attack aircraft, they were fired at from the ground by every possible weapon. As a result, an order went out to the German ground troops to imitate the Soviets and defend themselves against air attack with machine guns. This was OKH's first admission that, in these enormous spaces, the army no longer had nor could hope to have all the friendly command of the air it desired.

 

As the German forces consolidated their hold at Smolensk on the Dnieper, Hitler and the Army High Command engaged in the famous debate as to which objective, Moscow or the Ukraine, should be given priority. On Hitler's orders, Hoth's 3d Panzer Group now followed Fliegerkorps VIII in turning to the assistance of Army Group North, though without much success since the country between Smolensk and Leningrad contains some of the largest and densest forests in the whole of Russia. We cannot debate here whether or not it was feasible, let alone desirable, to pursue the offensive against Moscow at this time. Suffice it to say that this author's research indicates that the logistic basis for this action was not available since the railways supplying the German infantry forces in particular (unlike the armored groups, they did not have their own motorized transport capable of bringing up supplies from the rear) had been left hundreds of miles behind. 

Meanwhile, far to the south, Army Group South advanced from Poland. Its left wing was formed by Sixth Army, acting as a flank guard against possible counterattacks coming from the Pripet Marshes; next, from north to south, came 1st Panzer Group, Seventeenth Army, and, emerging from Rumania on 2 July, Eleventh Army operating in conjunction with some Rumanian forces. As usual, the planners at OKH had staked their main hopes for operativ warfare on 1st Panzer Group, though not to the extent of freeing it from subordination to Sixth Army. (Throughout the summer of 1941, German panzer groups continued to be under the orders of infantry armies in order to prevent them from wandering off on their own.) The 1st Panzer Group was expected to break through the frontier defenses and advance very fast, its mission being to outflank the Soviet forces on its right until, by turning southward to the Black Sea, it could crush them in a Kesselschlacht against Eleventh Army coming from its Rumanian "balcony." This strategy in turn rendered the south flank of the panzer army open to attack. As always, there were wide gaps between the advancing German columns, and Fliegerkorps V had already been instrumental in beating back a corps-sized Soviet counterattack on 26 June in the area between Lutsk and Rovno.  

 

It soon became clear that the Soviet forces in this area, which formed the Southwestern Front under Gen M. P. Kirponos, were better commanded than elsewhere. In the sector of Seventeenth Army, they slowed down the German advance, did not allow themselves to be disrupted, and, fighting for as long as the situation permitted, made what were on the whole well-ordered retreats. Some of Gen M. I. Potapov's Fifth Army withdrew into the marshes to the north, where the Luftwaffe was unable to find them and from which they were to emerge later in the campaign. Others fell back on the Stalin line and, after that line was breached, tried to cross the Dnieper to safety. It was the task of Fliegerkorps V, attached to the left wing of the army group, to prevent the retreat. At first it did so with some success by attacking roads, railroads, and transportation centers in Lvov, Brody, Zlotuv, Zhitomir, Berdicev, Starokonstantinov, Belaya Tserkov, and Kazatin. Other than an occasional thunderstorm, the weather was good and the country completely open. Hence, these attacks, which went on day and night, were as successful as any that the Luftwaffe mounted in Russia throughout the campaign. A high point was reached on 30 June when two or three Soviet motorized columns, moving four abreast, were caught near Lvov and subjected to what amounted almost to a slaughter. However, Fliegerkorps V did not have dive-bombing units under its command. It was instrumental in keeping the air clear of Soviet aircraft, but its ability to offer direct support to First Panzer Army was limited. This was one factor that caused the advance of that unit to be considerably slower at first than had been planned.

 

Penetrating farther to the east, the Germans faced different problems. Whereas the nature of the terrain in the north had caused the advance to proceed along the forest tracks, the countryside in the Ukraine presented no limitations. Under such circumstances, it did not take long before Luftflotte 4, like Army Group South as a whole, found its forces threatened by lack of cohesion. The problem was made worse by the almost complete absence of roads. This caused the army and air force to compete for the few available roadways in order to bring supplies forward. At times it became necessary to supply the forward units of the Luftwaffe by air, always a very costly operation. As a result, the bombers were increasingly left behind, the fighters could not reach the front at all, and only the attack aircraft got proper logistic support. Although bridges on the Dnieper were repeatedly hit by sorties flown by Fliegerkorps V, traffic over them was never completely halted because they proved difficult to destroy. Attacks were also made on the railway network east of the river in the Konotop-Glukhov- Gorodishche-Priluki-Bakhmach region. Tactical results were very good, with some 1,000 railroad cars destroyed, but again the withdrawal of at least some Soviet forces in front of 1st Panzer Group could not be prevented.

 

Meanwhile, having reached the Dnieper on 10 July, 1st Panzer Group was forbidden by Hitler from crossing it. Thereupon the Germans turned their armored spearheads towards the southeast, keeping west of the river. This brought them into the rear of the Soviet armies that were slowly falling back in front of the German Seventeenth Army and led to the creation of the pocket at Uman. Here Fliegerkorps V was more successful than before in helping the ground forces seal off the pocket and prevent the escape of the Soviet forces, particularly since it was assisted by units of Fliegerkorps IV coming from Rumania in support of the German Eleventh Army. However, this meant that Sixth Army in the north had to be left completely unsupported. That army accordingly had to beat off the Soviet Fifth Army coming out of the Pripet Marshes and directing its attack against the exposed rear of 1st Panzer Group. It did so, but at the cost of slowing its own advance to a snail's pace and thereby laying-even though unintentionally-the foundations for the subsequent vast Kesselschlacht of Kiev.

 

When Army Group South had finished clearing the Uman pocket and was preparing to cross the Dnieper on 7 August, it found itself exposed to a sudden counterattack by the Soviet Twenty-sixth Army on the right flank of the German Sixth Army. This, had it succeeded, might have cut the army group in two or at least driven a deep wedge between the widely separated German forces. As usual, the only force immediately available to hold off the threat was the Luftwaffe; and, as was often the case during this period, it did so quickly and effectively, though at the cost of switching to battlefield operations for which many of its aircraft were not really suitable. A week was to pass before the German forces coming from the north and the south simultaneously (one of 1st Panzer Group's armored divisions had to turn around and retrace its previous movement) were able to halt the Soviets and throw them back across the river. During the first decisive days, Fliegerkorps V, throwing in every available unit and forced by unfavorable weather to fly at altitudes as low as 50-100 meters, fought on its own and later claimed to have destroyed 94 tanks and 184 motor vehicles.

 

By the middle of August, although isolated pockets of enemy resistance remained, the situation west of the Dnieper could be regarded as stabilized. From 17 August on, Luftflotte 4 accordingly moved its efforts farther to the east, hitting the communications center of Dnepropetrovsk day and night in the hope of preventing the Soviets from making further withdrawals and preparing for the Germans' own forthcoming offensive. Owing partly to distance and partly to sheer wear and tear, the number of fighters available to Fliegerkorps V was down to 44. Although these fighters performed marvels (on 30 August, there was an announcement that 1,000 Soviet aircraft had been shot down in air-to-air combat), they could not be everywhere at once. Hence, a Soviet attack on the bridge across the Dnieper at Gornostaypol, which the Germans had taken in a coup de main, was successful in delaying the advance of Sixth Army once again. Fliegerkorps V was, however, able to protect the first bridgehead built by 1st Panzer Group across the Dnieper on 8 September against determined Soviet attempts to attack it from the air.

 

Throughout this period, Fliegerkorps IV, with its weaker forces, continued to fly missions in support of Eleventh Army, which was approaching the Crimea. It attacked the bridges across the Dniester to prevent Soviet reinforcements and to prevent the escape of Soviet forces from the Uman pocket. The center of gravity gradually shifted eastward until Odessa, used by the Soviets in an attempt to evacuate their forces by sea, became the most important target.  When the Rumanians crossed the Dniester in the middle of July, Fliegerkorps IV typically switched back to close support. The same pattern was thus revealed in this somewhat separate theater as everywhere else. If only because not even Richthofen's close support experts could respond to the army's demands in less than two hours, the Luftwaffe's normal preference was for what the Germans called operativ warfare and what we would call behind-the-front interdiction. At least during the early phases of the campaign, close support came into its own only when a clear geographical line divided the forces on both sides or else when a Soviet counterattack created an emergency.

At 0300, 22 June 1941, the Luftwaffe opened the campaign by the now-standard method of a surprise strike at the enemy's airfields. The weather that day was almost perfect-warm and sunny with a slight haze that cleared up later during the day. For reasons that remain inexplicable to this day, the Soviets had made no preparations to oppose the aggressors. The German pilots found Red aircraft by the hundreds lined up wingtip-to-wingtip on the aprons, and they reported very little opposition on the ground or in the air.  According to whether they consisted of bombers, fighters, or dive bombers, German units flew as many as four, five, six, or even eight missions per day-astonishing figures attributable to the simplicity of the machines, the often short distances that had to be covered, the excellence of the ground organization (including a specially developed apparatus that allowed nine aircraft to be refueled simultaneously), and the unparalleled determination of the crews. The first attack was carried out by 637 bombers (including dive bombers) and 231 fighters . Reportedly it hit 31 airfields, three suspected billets of high-level staffs, two barracks, two artillery positions, a bunker system, and an oil depot, all at the cost of two fighters missing. By the evening of the first day, some 1,800 Soviet aircraft were reported destroyed, the great majority on the ground but 322 of them shot down as they rose to meet the German machines. (This disproportion was to prove important later on because Soviet aircrews had not been affected and would survive to fight another day.)

 

Meanwhile, photoreconnaissance was being conducted on a grand scale. It disclosed the existence of numerous additional airfields, 130 of which were identified and attacked during the next few days. By the end of the first week, the Armed Forces High Command was able to report the destruction of 4,017 Soviet aircraft against a loss of only 150 German ones.  By 12 July Soviet losses had risen to about 6,850. This included entire bomber squadrons flying obsolescent machines without fighter cover that were shot down like turkeys as they hurled themselves at the invading German columns. After the first few days, Soviet air operations were reduced to scattered attacks by small numbers of aircraft that appeared out of nowhere, dropped or fired their ordnance, and made off as best they could. Having achieved air superiority to the point that they could command the sky whenever and wherever they wanted, the Germans on 25 June felt that the time had come to shift the center of gravity to support their own ground forces. In so doing, they soon discovered that the number of aircraft available was never really sufficient to cover the vast theater of operations; this in itself made a coordinated system of operativ warfare difficult since the constant demands for air support tended to disrupt planning, dissipate the available forces, and hinder the creation of Schwerpunkte. Russian roads, often consisting of mere tracks, were difficult to attack because they were usually easy to repair or bypass. Attacks on Russian villages, designed to reduce houses to rubble and thus block the communications passing between them, seldom led to lasting results owing to the wide distances separating the houses and to the wood used in their construction. In the north, as well as on the fringes of the Pripet Marshes, extensive forests enabled even large units, particularly those consisting of infantry or cavalry, to escape observation from the air.

 

Still, in other ways the Russian countryside offered advantages to the attacker from the air. The density of the railway network was relatively low, there being only 52,000 miles of track (many of them single) in the entire gigantic country. Hence, the task of disrupting the lines and bringing traffic to a standstill did not appear as insoluble as it would have been if the USSR had been a developed Western country with many intersecting, parallel, and redundant lines of communication and numerous technically advanced facilities for repair and maintenance. In the center and south, the open, flat, almost treeless terrain-much like the American Midwest-made it nearly impossible for ground units to find cover against air attack except by utilizing the occasional ravines. A well-planned campaign should have exploited these advantages and avoided the obstacles. However, this was something that the Germans, operating with only relatively small forces and trying to achieve too many things at once, were never really able to do.

 

The Luftwaffe's central archives were destroyed at the end of the war, and no good information is forthcoming from the Soviet side. Therefore, what little quantitative data can be found on the impact of the German air attacks on the Soviet ground forces, transportation system, and logistics have to be put together from the scattered surviving records of individual Luftwaffe units. These show that Ju-88 light bombers of a single Kampfgeschwader (bomber group) belonging to Fliegerkorps II claimed to have destroyed 356 trains and 14 bridges, interrupted railway traffic 322 times, and flown 200 sorties against troop concentrations, barracks, and supply depots in support of Army Group Center in "indirect" operations between 22 June and 9 September. During the same period, and acting in "direct" support of the army, the same unit claimed to have destroyed 30 tanks and 488 motor vehicles in addition to flying some 90 sorties against artillery positions. The Me-110s (twin-engined fighters) of another group claimed to have destroyed only 50 trains and 4 bridges between 22 June and 27 September but compensated by scoring 148 tanks, 166 guns, and 3,280 vehicles of all kinds.

 

As the records of many ground units show, Soviet opposition in the air during this period was so weak as to be almost negligible. This permitted even single-engined fighters to be diverted away from the escort role to attacking ground targets, and so one Jagdgeschwader (fighter group) flying in support of Army Group Center was able to report 142 tanks and armored cars, 16 guns, 34 locomotives, 432 trucks and one train destroyed. Certain entries in the diary of the chief of the German Army General Staff-who himself relied on information originating in the Luftwaffeshow that these attacks were not without effect on ground operations. On individual occasions, they deprived the Soviet armies of supplies, blocked reinforcements, and created congestion on the Ukrainian railroads in particular. However, the available evidence does not permit a detailed reconstruction of the impact of these operations on the campaign as a whole.

 

In the north, the German ground operations had three aims. They were to surround and cut off the Soviet forces in the Baltic countries (Eighteenth Army on the left), advance on the shortest line to Leningrad (4th Panzer Group in the center), and cover the right flank while keeping in touch with Army Group Center (Sixteenth Army on the right). These diverging objectives, imposed on Army Group North by Hitler himself, are open to criticism; however, because the terrain in this theater, as in Russia as a whole, became more open as the attacking army advanced further toward the east, gaps were bound to appear on the flanks of the advancing spearheads.

 

The German system of maneuver warfare was by now fully developed. Its consistent aim was to drive deep wedges into the enemy and to encircle his forces (consisting, as of 10 July, of 31 divisions and six independent mechanized brigades grouped together under Soviet Field Marshal Kliment Voroshilov's Northwestern Front). The speed of the advance was spectacular, reaching 40 miles per day during the first few days. Nevertheless, Army Group North never really succeeded in cutting off the main Soviet forces as it had planned to do. Nor did it have the infantry needed to seal what pockets that were formed; many Red Army units, though isolated from each other, remained intact or, at any rate, sufficiently cohesive to continue fighting, especially since the dense forests afforded plenty of room for them to hide. It fell to the Luftwaffe to leap into the breach and to identify and prevent counterattacks from developing into dangerous threats. This caused its independence to be gradually eroded until finally it was reduced to the role of a mobile fire brigade, just the kind of thing Luftwaffe leaders had always wanted to avoid.

 

For example, on 27 June units of Fliegerkorps I were instrumental in beating back a Soviet counteroffensive near Shaulyai (Schaulen), Latvia, where approximately 200 enemy tanks were destroyed. 24 On 2 and 3 July the same units first helped breach the fortifications along the old border and then, switching back to operativ warfare, attacked the bridges over the Dvina River in order to prevent the Soviets from making good their escape to the northeast. In this they were only partly successful. On 6 July it was the turn of the Red Air Force to try and wreck the bridges over the Dvina in order to slow down the German pursuit. This enabled General Keller's Luftflotte 1 fighters to shoot down 65 out of 73 attacking aircraft, thus putting an end to large-scale enemy attempts to interfere with ground operations in this sector. Units of Luftflotte 1 also assisted in supplying Sixteenth Army during its advance, given the single road (in reality, little better than a forest track) leading from Pskov toward Narva had not yet been cleared and was dominated by isolated Red Army units.  

 

Thus, during the first two weeks of the campaign, all the ways in which an air force might assist maneuver warfare were displayed to the fullest. As flying units were moved forward onto newly captured Soviet airfields, the distances between them and their targets diminished. Beginning in the second week of July, this permitted the Luftwaffe to mount repeated attacks on the Moscow-Leningrad railway with the aim of severing communications between Russia's two most important cities .28 Like others after them, however, the Germans were to learn that railways, while not difficult to disrupt, were not difficult to repair. Though traffic suffered, the line could not be completely cut until the ground forces had advanced sufficiently to throw a ring around the city.

 

Beginning in the last week of July, Luftflotte 1 was reinforced by Gen Wolfram von Richthofen's Fliegerkorps VIII, which was detached from its original assignment to Army Group Center and brought up to the newly occupied Baltic airfields. Acting in his favorite role as a close-support expert, Richthofen repeatedly massed his forces to deliver concentrated blows at key targets. On 15 August they assisted Sixteenth Army in the capture of Novgorod. On 24 August their intervention was decisive in beating back a Soviet counteroffensive against the left wing of Army Group North at Staraya Russa. On 28 August they helped bring the attack on Tallinn (Reval) to a successful conclusion. However, despite repeated attempts and many hits on both warships and freighters, Luftflotte 1 was unable to prevent the bulk of the Red Fleet from retreating to Kronstadt and Leningrad. In a sort of mini-Dunkirk, the Soviets succeeded in evacuating some of their troops in the Baltic, and these were later instrumental in the defense of Leningrad.

 

Fliegerkorps VIII was still available when the offensive against Leningrad got under way on 26 September. Against strong antiaircraft fire, it helped the units of Fliegerkorps I attack targets within the city as well as ships in the harbor; a Soviet counterattack in the direction of Lake Ladoga was beaten off, and the ring around "the capital of Bolshevism" closed. However, only a few days later, Richthofen's units were taken away and sent back to support the offensive of Army Group Center against Moscow. Army Group North itself had now been deprived of the bulk of Fourth Panzer Army, which was also sent to the Moscow area. Relying on a single motorized corps (XXXIX), it was still able to carry out a last offensive effort, crossing the Volkhov River in the direction of Tikhvin, where it hoped to link up with the Finns on the river Svir. Though its aircraft (Ju-88s) were not really suited to the task, especially in view of the densely wooded nature of the terrain, Fliegerkorps I flew missions directly supporting the operation as well as attacking railway lines leading into the area. After bitter fighting, Tikhvin fell on 9 November. However, the battle was by no means at an end, and the Germans, finding themselves counterattacked by three Soviet armies under Gen K. A. Meretskov, were forced to evacuate it a month later. By this time, bad weather, including persistent winter fog, affected the operations of Luftflotte 1 to the point where it was unable to reconnoiter effectively, let alone mount coordinated attacks on what targets could still be identified. The operations of Army Group North became essentially static and were destined to remain so until the siege of the city was lifted in January 1944.

 

In this siege, Luftflotte 1, its forces much reduced by losses and by the limited availability of aircraft, was assigned the task of attacking military targets within the city as well as the supply routes leading to it. In spite of the reported destruction (by 23 August) of 2,541 enemy aircraft plus 433 probable kills, Soviet opposition began reviving in the autumn, and by the end of the year the city was defended by several hundred fighters, 300 balloons, and 600 antiaircraft artillery barrels. Although the Germans never lost the ability to gain air superiority where and when they wanted, they were unable to make much headway in capturing Leningrad. From September through December 1941, the Luftwaffe dropped a total of 1,500 tons of bombs on targets in and around Leningrad; this was less than the amount dropped by Allied air forces on a single German city in a single night in 1944-45. As a result, the lifeline to Leningrad, which as of 18 November consisted of motor convoys (later a railway as well) crossing over frozen Lake Ladoga, could never be completely severed for any length of time.

 

As 1941 drew to an end, the troops of Luftlotte 1, living under impossible conditions and prevented by the weather from flying much of the time, were drowning their sorrows in alcohol.

As the German forces were being assembled in the east slowly at first and then more rapidly from February 1941, when the real buildup began-the Luftwaffe was still engaged in fighting England. Its first move consisted of an attempt to destroy the Royal Air Force's (RAF) Fighter Command and gain air superiority in order to pave the way for a seaborne invasion. The Luftwaffe was unsuccessful, however, both because the Germans appear to have failed to realize the importance of sustained attacks on the opposing radar system and because the RAF, favored by geography that allowed it to withdraw its aircraft beyond the range of the German fighters, was able to dictate the pace of the battle as it saw fit.9 From the end of September 1940, the Germans, confronted by growing opposition, changed their tactics. First, they shifted to daytime bombardment of British "strategic" objectives. When that proved too expensive-again and again in World War II, it was shown that unaccompanied bombers stood little chance against modern fighters-they concentrated on nighttime attacks directed, insofar as any center of gravity can be detected, against aircraft factories and harbors. Britain's cities, particularly London, Birmingham, Bristol, Cardiff, Liverpool, Glasgow, and Coventry suffered heavily. Nevertheless, the Luftwaffe, its twin-engined light and medium bombers designed for participation in operativ warfare and not for waging an independent strategic campaign, never came close to forcing the British to their knees. Indeed, the realization of this fact was one of the factors that finally drove Hitler to decide to turn east.

 

The Luftwaffe received with mixed feelings the news that Germany was about to invade Russia. Many of its leaders, including Hermann Goering and his deputy, Eberhard Milch, tried to warn Hitler against waging a two-front war because of the inevitable dissipation of forces that would follow.  Others, however, expressed relief at the anticipated return from independent "strategic" warfare to the more congenial operativ form of war to be waged in conjunction with the rest of the Wehrmacht. "Finally, a real campaign" was the comment of Chief of Staff Hans Jeschonnek. Directive No. 21 had charged the Wehrmacht with "destroying the Soviet forces in a rapid campaign" in order to prevent their withdrawal into the interior. Within this general framework, the task of the Luftwaffe was defined as (1) knocking out the Soviet air force in order to obtain and maintain air superiority over the theater of operations ; (2) supporting the operations of Army Group Center and, in a more selective form (Schwerpunktmaessig, literally "by way of forming centers of gravity"), those of the other army groups; (3) disrupting the Soviet railway net in order to prevent reinforcement on the one hand and withdrawal on the other; and (4) capturing important transportation bottlenecks such as bridges ahead of friendly forces by using parachutists and gliders.  "In order to use all available forces in support of the Army," the directive went on, "the enemy's armaments industry should not be targeted during the main campaign," meaning that the German forces would be directed against the regular Soviet forces rather than at whatever resistance would remain after the destruction of those forces. Only after the end of the mobile phase of operations would attacks on the Soviet armaments industry, chiefly in the Urals, get under way.

 

In preparation for the campaign, the Luftwaffe divided its forces into three Luftlotten. (The forces that operated in support of the Finns in the far north will not be considered here, since there was little opportunity for maneuver warfare there.) Each was clearly earmarked for the support of one army group, although from the command and control point of view, there was no question of subordinating air force units to ground headquarters-but rather only of cooperation between them. In the north, Luftflotte 1 was commanded by Gen Alfred Keller. His flying units, consisting merely of a single air corps, Fliegerkorps I, and a few smaller forces, possessed a total of 592 transport and combat aircraft (453 operational), plus 176 reconnaissance and liaison machines (143 operational). In the center, Field Marshal Albert Kesselring's Luftlotte 2 was much stronger with two Fliegerkorps (II and VIII)-1,367 transport and combat aircraft (994 operational) and 224 reconnaissance and liaison machines (200 operational). Finally, Gen Alexander Loehr's Luftlotte 4, with two air corps (Fliegerkorps IV and V), supported Army Group South. Its forces consisted of transport and combat aircraft (694 operational), plus 239 reconnaissance and liaison machines (208 operational). The total number of combat aircraft (bombers, fighters, and close support) was 2,713, of which 2,080 were operational. Thus, in spite of the huge task with which it was faced militarily as well as geographically, the German air force in the east had a strength no greater than it had been during the French campaign in the previous year. This reflected the fact that fully one-third of its forces had to be left to fight in the west, the north (Norway), or the Mediterranean; qualitatively, too, the forces on the eastern front were not the most modern since obsolescent aircraft no longer capable of serving against Britain were still considered fit to confront the Soviets .  

 

Throughout the first half of 1941, the Luftwaffe was hard at work preparing for the campaign. The aircraft industry and training facilities were expanded until they were considered able to keep up with anticipated losses, but no more. Luftwaffe units flew numerous photoreconnaissance missions inside Soviet territory, and the list of targets within a 200-mile zone from the frontier had been completed by the end of April 1941. Meanwhile, many new airfields were built and existing ones improved, the necessary ground organization put in place, and the required reserves of POL, ammunition, and equipment assembled. The last stage, starting towards the end of May, was to bring in the flying units themselves under a heavy cloak of secrecy. In Hitler's own words, the German ability to win this most ambitious of all campaigns rapidly and decisively depended on tanks and aircraft working together in order to "break the Russian." Thus, the importance of a smooth system for air-to-ground cooperation was greater than ever; yet, when hostilities broke out, the organizational problems of securing it had by no means been solved in spite of many suggestions raised by Richthofen and other key Luftwaffe commanders.

 

The system that divided responsibility between the Kolufts on the one hand and the Flivos on the other remained in force. A process of decentralization took place as both types of officers were increased in numbers until, instead of there being one for each army and corps, one of each could be assigned to every division. Towards the end of 1941, the Flivos even started accompanying some individual regiments, although there were never enough of them to expand this system to the army as a whole.  Each air corps (instead of air fleet, as formerly) headquarters now included a Nahkampfuehrer. His task was to coordinate all Luftwaffe support for the army, for which purpose he was given operational control over all units available for that mission. Some progress was also made in providing ground and air units with common radio apparatus to enable them to communicate directly with each other. At Fliegerkorps VIII, experienced Stuka pilots were now riding in Mark III tanks and acting as forward air controllers. Nevertheless, the German army as a whole still depended on various agreed-on, rather primitive, visual recognition signals to prevent attacks on friendly troops. Above all, Goering steadfastly refused any measures that would have assigned the army any control over the sorties flown by Luftwaffe combat units, and the Germans had to wait until 1944 for a real solution for that problem.

 

Like the Soviet Union in general, the Red Air Force at this time was something of a mystery to the Germans.  The chief of intelligence at the Luftwaffe General Staff was Gen Joseph Schmidt, an opinionated officer whose estimates of the situation reflected his Nazi prejudices. He put total enemy strength at approximately 10,500 machines, including 7,500 in Europe. Supposedly the Soviets had 1,360 reconnaissance aircraft and bombers, plus perhaps 2,200 fighters (including those added during the first half of 1941). Most of the machines were supposed (correctly as it turned out) to be inferior to their German equivalents both in general flying characteristics and, to an even greater extent, in specialized instruments such as radio and navigational aids. The Germans assumed the mass of the Soviet air force personnel, including pilots, to be primitive and ill-trained by Western standards and their organization as a whole to be heavy-handed and inflexible. They believed that once the Germans occupied the industrial centers in European Russia, the Soviets would not be able to keep up their strength in aircraft and would be reduced to fighting in uncoordinated remnants-a belief that turned out to be grossly mistaken.

Though the Battle of Kursk is rightly considered a tank engagement, the struggle in the skies was no less important. The Luftwaffe gave the panzer divisions excellent aerial support, but the Red Air Force was to prove the eventual master in the air.

 

The Luftwaffe commitment at the beginning of Operation Citadel was 1800 aircraft. This figure represented some two-thirds of the machines deployed on the entire Eastern Front. The bulk of this force was concentrated to support the southern pincer under VIII Air Corps commanded by General Otto Dessloch. A squadron commander during World War I, Dessloch had vast experience, having led various Luftwaffe units prior to the Kursk operation. Under Dessloch's leadership, VIII Air Corps controlled the flying units of 4th Air Fleet, 1st Hungarian Air Division and I FlaK (antiaircraft artillery) Corps, disposing a total of 1100 aircraft. Included amongst these flying formations were seven units of dive-bombers, the infamous Ju 87D Stuka.

The Stukas were expected to carry out their classic role, established during four years of war, as flying artillery plunging out of the skies to bomb and strafe the enemy immediately ahead of the panzer wedges. The near-vertical dive that preceded bomb release was accompanied by a howling wail, as the pilot aimed his aircraft at the target, a wail that froze the blood of the men on the ground, convincing them that they as individuals had been specially chosen for death.

 

Operation Citadel was the last time the Stuka would be employed in this manner, as its performance no longer matched the demands of the Eastern Front. When their dive-bomber role was rescinded, all the remaining Stukas were transferred to low-level ground-attack duties, and it was during the Kursk operation that Stuka "tank busters" were employed on a wide scale for the first time. A 37mm antitank gun was fitted under each wing, and this weight of fire in the hands of an expert such as Flight-Lieutenant Hans-Ulrich Rudel was to wreak havoc in the Soviet tank fleets. It is claimed that Rudel destroyed 12 tanks on the first day of Citadel alone.

 

Another first for the Luftwaffe at Kursk was the employment of Schlactsgeschwaders (ground-attack wings) utilizing Focke-Wulf Fw 190 A-4s and Henschel Hs 129 B-2/R2s in large numbers. The Henschel Hs 129 had been designed specifically as a "tank buster". In its nose were two 7.92mm machine guns and two 20mm cannons, but its real power was in its main armament, a single 30mm Mark 101 or 103 cannon housed in a gondola beneath the fuselage. When brought to bear on the thin engine housing at the real of a tank, unarmoured lorries or the timber-built Soviet bunkers, this weight of fire was usually fatal. The Fw 190s operated closely with the Hs 129s, dropping SD1 and SD2 fragmentation bombs to disrupt the Soviet infantry attack lines.

 

The slow speed of the ground-attack aircraft such as the Hs 129 and the Stuka necessitated close fighter cooperation to allow their crews to concentrate on the job in hand, and this was to be provided by the Messerschmitt Bf 109 G-6 and Focke-Wulf Fw 190 A-5s. The armament of the Fw 190 — four 20mm cannon in the wings and two 7.92mm machine guns in the forward fuselage — coupled with a speed of 605km/h (382mph), made it a fighter to be reckoned with. The weaponry and performance of the Bf 109 was similar. Heavier bombing operations were to be conducted by other tried and trusted aircraft, such as the Heinkel He III and the Junkers Ju 88.

 

The Luftwaffe supported the northern pincer with Colonel-General Ritter von Greim's 6th Air Fleet, which consisted of the 1st Air Division, the 12th FlaK Division and the 10th FlaK Brigade. The mixed bag of antitank fighter and bomber aircraft numbered 730. Amongst these were three Stuka groups. The guns of the FlaK units were highly effective weapons, particularly the 88mm. However, such was the effectiveness of the 88 against Soviet tanks that many FlaK batteries were assigned to the Wehrmacht to bolster the antitank gun formations which had less effective weapons. The consequence was that the protection available to Axis airfields was severely curtailed.

 

The Luftwaffe that now geared up for Operation Citadel was not the one that had dominated the Russian skies for almost two years. Commander of the Luftwaffe, Hermann Göring, had promised that no bombs would fall on the Reich. By early 1943 the emptiness of his words was proven daily by the Anglo-American bomber offensive that damaged Germany's industrial output and chiselled away at the people's morale. To counter this, Göring had withdrawn many fighter squadrons from the Eastern Front and diverted aircraft output to the West, with the consequence that the Eastern Front fought with diminished assets. To further compound this difficult situation, the Western air war was given priority in the allocation of fuel, so that the fuel allowance for the Battle of Kursk was 30 percent below its actual requirement.

 

However, the experience of the aircrews, the efficiency of the ground crews and the superiority of the machines were all factors that the ordinary German soldier took for granted; after all, had not the Wehrmacht enjoyed almost total air superiority over the Red Air force since the first hours of Operation Barbarossa? What the Landser in their trenches were unaware of was that the Red Air Force was now not, as it had been for so long, mere target practice for the Red Baron's proteges, but a real force to be reckoned with, and one to be taken very seriously indeed.

On 5 July the day dawned bright and warm. On the dusty runways of Belgorod, Kharkov, Poltava and Dnepropetrovsk the Ju 88 and He 111 bombers of VIII Air Corps lined up for take-off as the first waves of the Citadel air offensive, when the wireless monitoring service reported a considerable increase in Soviet air traffic, and soon afterwards the "Freya" radar at Kharkov detected the approach of large air formations from the east. These formations contained 132 Shturmoviks and 285 fighters of the Second and Seventeenth Air Armies, detailed to destroy the German bombers on the ground when their fighter escorts were not yet airborne. But this pre-emptive strike was not to succeed. The Soviet regiments were intercepted by the Bf 109 Gs of Jagdgeschwader (hunting formations) 3 "Udet" and JG 52 scrambled from Kharkov East and Mikoyanovka, which claimed 120 air victories in the opening air battle.

 

In the northern sector, the Germans reported that Soviet fighter reaction to 1st Airborne Division operations began only in the late afternoon, and the Fw 190 fighters of JG 51 and JG 54 had claimed 115 Soviet aircraft by nightfall. The committal of fighters to the abortive pre-emptive strike in the early morning left the VVS unable to contest Luftwaffe air supremacy on the southern flank of the salient, and in the north, Soviet replies to the Luftwaffe attacks were tardy and ineffectual. The two fighter corps designated to give frontline cover, Yumashev's VI Fighter Corps over the Central Front and Klimov's V Fighter Corps over the Voronezh Front, were unable to cope. Without adequate air cover, the Soviet ground forces lost confidence and the Wehrmacht began to make headway. Novikov had to give his attention first to the failings of his fighters and, as a result of his investigations, Yumashev and Klimov were both replaced, VI Fighter Corps being taken over by Major-General Yerlykin and V Fighter Corps by Major-General Galunov.

 

Nor were the Soviet attacks on German armour initially successful. Despite new antitank bombs, their RS-82 rockets and more formidable 37mm cannon, the Il-2 Shturmoviks failed to get through and stop the panzers rolling forward. Flying in small groups, the Il-2s and Pe-2s often lacked fighter escort or they were abandoned when the very first sign of trouble appeared.

 

On Khudyakov's orders, the Shturmoviks began to fly in much larger formations of regimental size to make escort easier, and to enable the Il-2s to break through and suppress ground fire by sheer weight of numbers and the persistence of attack. Flying in pelang formation - staggered line abreast — the Il-2s no longer made hasty passes at low level under favourable conditions, but carried out calculated dive approaches from under 1000m (3280ft) at angles of 30-40 degrees, releasing their bombs and rockets when 200-300m (656-984ft) from their target, and making repeated passes with cannon and machine guns.

 

At the end of the second day, in the north of the salient, the VVS had overcome its problems and was able to contain the German fighters, if not the bombers. But from 7 July the Sixteenth Air Army got into its stride and began to wear down the Luftwaffe. By 8 July Khudyakov was able to report on the improvement in Shturmovik potency, and the Luftwaffes power to control air space over the battle areas declined. The Luftwaffe was running out of replacements to maintain its squadrons at full strength, and the RAF began to range more freely over the German lines.

 

Although the Germans could still mount effective ground-support missions, in specific areas if not along the entire combat zone, their superiority was being eroded at an alarming rate. By the end of effective ground-offensive operations in the northern sector, the power of the Luftwaffe was much reduced.

 

The picture to the south was much the same. Soviet weight of numbers and the increasingly efficient use of machines whittled away at the numerically inferior Germans, and by 11 July the Luftwaffe was only able to achieve success in narrow areas such as supporting the thrust of II SS Panzer Corps towards Prokhorovka. As Rotmistrov described the scene over the battlefield of Prokhorovka from his command post:

"At the same time, furious aerial combats developed over the battlefield. Soviet as well as German airmen tried to help their ground forces to win the battle. The bombers, ground-support aircraft and fighters seemed to be permanently suspended in the sky over Prokhorovka. One aerial combat followed another. Soon the whole sky was shrouded by the thick smoke of the burning wrecks."

 

If Prokhorovka was, as Konev described it, "the swansong of the German armour", then Operation Citadel would mark the coming of age of the Red Air Force. For the first time since the outbreak of war, the VVS had met the Luftwaffe on almost equal terms, and although there was a long way to go before they reached the final victory, the Soviet air fleets had clipped the wings of Hitler's Luftwaffe and had gained control of their own skies once more.
