ON a bright August morning in 1915 a young German airman dived his single-seater scout monoplane out of the summer clouds over the Western Front. The English biplane beneath him swerved away at once, but too late; the single fixed machine-gun of the Fokker monoplane stammered briefly, stopped, then stammered again. The acrid scent of cordite fumes in his nostrils, the German pilot turned in his seat, watching with surprise as the enemy machine faltered in the air. Slowly at first, then rapidly gaining speed, it drifted lazily towards the earth below. Leutnant Max Immelmann, the German pilot, saw the biplane land heavily in a field, and knew then that he had gained his first victory. Later, he would have many other victories, and still later become known as the Eagle of Lille, but Immelmann would never equal his first achievement as a fighting airman. On that day in 1915 he unwittingly fulfilled the true purpose of a German fighter aircraft for the first time.
When the assassination of Archduke Franz Ferdinand of Austria and his consort in Sarajevo on 28th June, 1914, precipitated Europe into the wholesale slaughter that was to last for four long and weary years, Germany, in common with her opponents, was totally unprepared for war in the air. Eleven years after Orville and Wilbur Wright had made history at Kitty Hawk the aeroplane still remained something of a novelty to the narrow military mind. It was considered to be of little use except perhaps in a reconnaissance or observation role, secondary even to the splendid cavalry that would play such an unimportant part in this modem war.
Nevertheless, an Austrian, Igo Etrich, had already provided the basis for the future Imperial German Air Force. In 1908, he designed an attractive monoplane which became known as the Taube—or Dove—because of its graceful sweeping form and the remarkable resemblance it bore to a bird in flight. After various early flying successes, including an altitude record of 20,000 ft., Etrich sold the rights of his monoplane to the German Government, who handed the design to the Rumpler factory at Berlin-Litchtenberg for development. The twenty Taubes produced by the Rumpler concern proved to be such outstanding aircraft that eventually a number of other factories began manufacturing the little monoplanes, and by 1914 more than half of the total aeroplanes assigned for use with the German armies were of that type.
When von Kluck’s forces surged across Belgium and northeast France during the night of 4th August, 1914, Germany could muster some thirty-eight airships and about eight hundred assorted aeroplanes, all unarmed, and including the cumbersome L.V.G., Albatros and D.F.W. two-seater biplanes, which were later to prove so slow and unwieldy in action. These air units were distributed along the front in batches of six aircraft, known as Feldfliegerabteilungen, and were reserved for use in a reconnaissance or photography role, as had been anticipated. The Feldfliegerabteilungen were organised within the German Army on a basis of one to each Army H.Q., and also one to each Army Corps. Various experiments to provide a successful aircraft armament continued to be ignored by the German High Command, who simply failed to envisage the aeroplane as a fighting weapon. The carrying of pistols or rifles into the air thus became a normal practice during the first year of war.
The two-seater heavy biplanes, carrying a pilot and observer, and known as “B” machines, were the aircraft commonly used for reconnaissance purposes during 1914. Later, when these mounted a Parabellum machine-gun for rearward defence, they were designated as “C” machines. The little single-seater “A” machines, mostly Taube monoplanes, were particularly suitable for reconnaissance when advantage was taken of their fast, high-flying qualities, and Max Immelmann flew over Paris in a Rumpler model in the autumn of 1914 and dropped a note on the city calling upon the people to surrender. Strange as it may seem, history records that on both sides a well-aimed rifle bullet would occasionally find a target—Oberleutnant Reinhold Jahnow, Germany’s first pilot to be killed in action, fell on 12th August, 1914—but in those early days of military aviation casualties in the air were the exception rather than the rule.
Then, in 1915, the Fokker E.1 monoplane appeared over the Western Front, and immediately the fighter aircraft was born. As used by Max Immelmann, Oswald Boelcke, and later a number of other famous German airmen, the small 80-h.p. Eindecker monoplane designed by a young Dutch engineer named Anthony Fokker created a milestone in the history of aviation. Of surprisingly conventional appearance, but with an excellent performance, the true secret of the Fokker monoplane’s amazing success lay in its armament, which completely revolutionised aerial fighting and achieved within the space of a few weeks unlimited supremacy for the German air forces in the field.
After examining a captured French Morane monoplane fitted with a primitive form of interrupter gear invented by an engineer named Eugene Gilbert, and used with some success by the pilot of the Morane, Roland Garros, Fokker designed a greatly improved mechanism which enabled a rigid forward-firing machine-gun to fire through the arc of an aeroplane airscrew without the bullets striking the blades. For the first time, a pilot could aim his aircraft directly at the enemy, using it as a steady gun platform; consequently the unsuspecting Allied reconnaissance biplanes with their clumsy rearward-firing Lewis guns were bound to suffer increasing losses. The peaceful early months of the war in the air had abruptly ended, and the unarmed Taubes and Aviatiks of 1914 were already fading away into the mists of time.
The new single-seater Fokker monoplanes were carefully allotted to only the most experienced German pilots, and originally distributed on a basis of two fighters to each existing Fliegerabteilungen for protection of the slow two-seater observation biplanes. However, the Aviation Staff Officer of the 6th Army, Major Stempel, quickly saw that the monoplanes could be used to better purpose if they were formed into definite fighter units, and, on his own initiative, commenced a reorganisation of the machines in his own area. At about the same time that Major Stempel ordered the formation of three units of fighter monoplanes at Douai, General Ludendorff decided that the air forces had now grown to such an extent that it was time for them to break away from the Army; this eventually led, with the Kaiser’s approval, to the establishment of the Deutschen Luftstreitkrafte, or German Air Force, with General von Hoeppner placed in command. Slowly but surely, military aviation was coming into its own.
The three single-seater fighter units, or Kampfeinsitzerkommandos, organised by Major Stempel, immediately began to prove their worth in action, and two Fokker monoplane pilots, Max Immelmann and Oswald Boelcke, began the steady rise to fame later to earn them Germany’s highest award for valour, the Ordre Pour le Mérite, while operating from Douai. During the long winter of 1915 and the spring of 1916, they and the other Eindecker pilots waged a bitter and unceasing war against the depleted Allied observation aircraft; yet the persistently offensive policy of the Royal Flying Corps continued to carry its machines relentlessly into the enemy skies, regardless of the odds that faced them. In the early months of 1916 two new British aircraft, the De Havilland 2 scout and the F.E.2b two-seater fighter, appeared on the Western Front to challenge the German air supremacy. Both were pusher-engined machines, fitted with free forward-firing Lewis guns, a partial answer to the yet unsolved mystery of Anthony Fokker’s interrupter mechanism. A little French sesquiplane scout, the Nieuport 17, came into action about the same time, and in the hands of such outstanding airmen as Albert Ball and Georges Guynemer fought, outflew, and gradually destroyed the Fokker menace. With it, in the summer of 1916, passed Max Immelmann, the Eagle of Lille, the monoplane he was flying shaken to pieces by a faulty engine.
On the morning of 1st July, 1916, the incredible weight of shellfire that had pounded the German trenches for a full week reached a climax of fire and steel, raining down death and destruction at a rate hitherto unequalled in war. As the British infantry went over the top, wave after wave, and the German machine-guns broke the brief silence with their heavy repeating clamour, the Royal Flying Corps rose to find an unchallenged sky. Ten thousand feet below, the running khaki figures struggled forward until they fell like com before the scythe, their voices drowned for ever by the merciless hammering of the guns; but that first day of the tragic Somme offensive remained unforgettably quiet and serene for the men who fought in the air.
It could not last, of course. Oswald Boelcke, the young Saxon schoolmaster’s son who had achieved such success with the Fokker monoplane over Verdun, had already suggested the formation of new units, to be known as Jagdstaffeln, elite squadrons whose only purpose would be to invite combat and regain the initiative from the Allies. Boelcke was much more than an outstanding fighter pilot; he was also a brilliant strategist, whose tactics for waging a successful air war would later prove as sound in the Battle of Britain as they did during the weary struggle of the Somme. After an inspection of the Southeastern Front, he returned to Douai to find that his suggestions had been fully approved by the High Command, and he was ordered to supervise the formation of two fighting squadrons. Jagdstaffel 1, commanded by a Hauptmann Zander, came into being on 23rd August, 1916, and a week later Jagdstaffel 2, under Boelcke, was formed at Lagaicourt. The man who had fought at the side of Max Immelmann lost no time in turning his pupils into expert fighter pilots; Werner Voss, Erwin Boehme, and young Leutnant Manfred von Richthofen were three of the novices who listened to the wisdom of Boelcke and later found glory because they remembered it. Two new types of single-seater biplane fighter aircraft were introduced almost simultaneously to the new Jagdstaffeln, or Jasta, as they were often known. The Halberstadt D.II, the first German biplane to be fitted with twin synchronised machine-guns, was destined to be brilliantly but only temporarily successful. Faster than the D.H.2 it opposed, it was nevertheless not easy to control, and required the skilful hands of an experienced pilot, yet at the same time it did much to regain Germain air supremacy in the autumn of 1916. The Albatros D.I was faster and more manoeuvrable than any Allied aircraft in service at the time. Fitted with the same armament as the Halberstadt, the Albatros was a much more attractive design, with a streamlined fuselage remarkable for the period, a rounded airscrew spinner, and powered by a 160 h.p. Mercedes engine. In later versions, which were the backbone of the German fighter forces until 1918, the struts were altered to the famous Vee layout already in use on the French Nieuport 17, and to be seen a year later on the Pfalz D.III.
On 17th September Boelcke led Jasta 2 into action for the first time. With him in the formation was Manfred von Richthofen, then twenty-two years of age. The son of a Prussian aristocrat, he had transferred from the Uhlans to the Air Force in the first year of war, and a chance encounter with Boelcke, who was impressed by his boyish enthusiasm, quickly led to his transfer from the Russian theatre of operations to the Western Front. The slow two-seater aircraft that Jasta 2 met that day proved to be hopelessly inadequate to face the new Albatros scouts, and the brilliant strategy of Oswald Boelcke, so often imparted to his willing pupils, sent six F.E.2b and two B.E.2C machines to the shell-torn earth below. Richthofen destroyed an F.E2b manned by Second Lieutenant Morris and Lieutenant Rees, his first victory in a battle which was destined to be the prelude to bitter fighting between Jasta 2 and the Royal Flying Corps.
As the warm September days slid by the new Jagdstaffeln gained experience in a baptism of fire that might well have consumed them, and during October the air fighting continued without respite for either side until by the 17th of that month Boelcke had shot down thirty-five enemy aircraft. Then, on 28th October, Jasta 2 suffered a tragic loss when Germany’s most outstanding fighter pilot, the idol of a nation, was killed. That ill-fated afternoon, Oswald Boelcke led his formation into battle against some D.H.2s of No. 24 Squadron, Royal Flying Corps. Together with Erwin Boehme, who was flying alongside him, Boelcke dived in pursuit of one British machine, then abruptly banked away when another D.H.2, hammered by Richthofen’s guns, hurtled across his line of sight. Boehme’s aircraft swerved, then touched Boelcke’s black Albatros, which staggered away with the interplane struts and upper wing collapsed and breaking asunder. Slowly but surely it fell into a spin, and plunged headlong to earth near Bapaume. So passed Oswald Boelcke, the man responsible for turning a collection of men and machines into efficient fighting squadrons, and then outlining the tactics that would regain Germany the air supremacy that her defensive policy so badly needed. His instructions—the famous dicta of Boelcke—were the most valuable legacy any airman could leave to his successors, and perhaps his greatest achievement was the way in which they so unfailingly stood the test of time.
By Imperial decree, Jasta 2 was named Jasta Boelcke after the death of its leader. Leutnant Stephen Kirmaier assumed command of the Jagdstaffel, but was killed in action within a month; Hauptmann Waltz was his successor. While the air battles raged unceasingly over the Somme during the winter of 1916–1917, the whole German Air Force was undergoing a complete reorganisation, which eventually led to the distribution of all the existing Feldfliegerabteilungen into definite fighter, bomber, reconnaissance or photography units. Thus, as the fighting squadrons, or Jagdstaffeln, increased in numbers, at the same time battle flights, known as Schutzstaffeln, and bombing units, designated Bombenstaffeln, came into existence.
Meanwhile, the Royal Flying Corps offensive continued unabated, despite rising casualties and the vital need for faster single-seater aircraft. On 23rd November, Major Lanoe George Hawker, holder of the Victoria Cross and a contemporary of Oswald Boelcke, fell to the guns of Manfred von Richthofen; he was the eleventh victim of the man soon to be Germany’s leading air ace. The indomitable spirit of the Allied airmen at that time was typified by Captain Albert Ball, already recognised along the front as one of the most outstanding British fighter pilots. He had taken part in twenty-three battles within the space of a fortnight, and was utterly exhausted when he reluctantly agreed to return to England for a rest, only a few weeks before the useless struggle for the Somme finally died away in the November of 1916.
The year closed with the hopeful introduction of a new British single-seater fighter biplane, the Sopwith Pup, which not only featured a synchronised forward-firing Vickers machine-gun but also had a performance that easily matched the speed and manoeuvrability of the Albatros D.III scouts then opposing the Royal Flying Corps. Nevertheless, neither the Pup nor the latest French scout, the Spad, which had also made an appearance, were the decisive air weapons the Allies needed, and many months would pass before the adversaries of the German Air Force were in a position to meet it on equal terms.
The German Naval Air Service came into being in 1912 as an essential part of the Imperial Navy, and a year later was divided into an airship section, known as the Marine Luftschiffabteilung, and an aeroplane and seaplane section, designated the Marine Fliegerabteilung. Due to the great interest and enthusiasm that the huge Zeppelin dirigibles mistakenly engendered in the German people before the war, the Naval Air Service in 1914 possessed only about twenty aeroplanes and a few seaplanes, and the Marine Fliegerabteilung continued to be neglected as a fighting service until 1917, when the remarkable Hansa-Brandenburg seaplanes designed by Ernst Heinkel were introduced, proving highly successful in many an air action over the North Sea.
Germany commenced her airship offensive against England in 1915, with a number of scattered bombing attacks on the coastal and rural areas. These early onslaughts, mostly made by naval dirigibles, were largely ineffective, but as the raids increased, it became obvious to the British War Office that the situation called for an immediate reorganisation of the sadly insufficient ground and air defences. To this end, anti-aircraft guns and night-flying aircraft appeared for the protection of London near the end of the year, and these, particularly the aeroplanes, eventually mastered the huge and awe-inspiring Zeppelins acclaimed by Germany as instruments of wholesale destruction.
However, in 1915 the airships remained a definite threat to an uncertain London. The latest type of Zeppelin in use at that time had an internal keel gangway, three gondolas mounting a number of machine-guns, balanced monoplane rudders and elevators, and was powered by four heavy Maybach engines. On the night of 8th–9th September, 1915, the L. 13, commanded by Kapitanleutnant Heinrich Mathy, perhaps the most resolute officer in the Luftschiffabteilung, bombed London and caused widespread damage, at the same time inflicting a number of civilian casualties. After three Zeppelins had again reached the capital in the October, Britain strengthened her home front defences, but both naval and military airships continued to attack London with some success until the late summer of 1916, when the first German airship to fall on English soil was shot down.
The Shutte-Lanz wooden-framed dirigible SL.11 was cruising over the London area on the night of 2nd–3rd September, 1916, heedless of the searchlights that probed the sky all around her, when Lieutenant W. Leefe Robinson, flying a B.E.2C biplane, dived to the attack. As he sped along the vast length of the airship he fired two drums of alternate Brock and Pomeroy explosive and incendiary ammunition into her, without any noticeable effect, and then emptied a third drum into one spot at the rear of the dirigible. Immediately, the ill-fated SL.11 erupted into a roaring mass of flame that turned the night sky brighter than any day, then tilted and plunged blazing to earth at Cuffley, in Middlesex, with the loss of all sixteen members of her crew.
The destruction of the Shutte-Lanz airship proved to be the beginning of the end for the Zeppelins. Later in September, two more of the great lighter-than-air craft were shot down, and then on the night of 1st–2nd October, the L.31, commanded by the famous Heinrich Mathy, was attacked by Second Lieutenant W. J. Tempest, who was based at North Weald. Undeterred by the heavy machine-gun fire directed at him from the airship’s gondolas, Tempest dived towards the Zeppelin, raking her with burst after burst of the devastating Brock and Pomeroy ammunition. “As I was firing,” he reported afterwards, “I noticed her begin to go red inside like an enormous Chinese lantern. She shot up about two hundred feet, paused, and came roaring down straight on to me before I had time to get out of the way. I nose-dived for all I was worth, with the Zeppelin tearing after me … I put my machine into a spin and just managed to corkscrew out of the way as she shot past me, roaring like a furnace.” The Zeppelin fell at Potters Bar, and the life of Kapitanleutnant Heinrich Mathy was ended.
During the last airship raid of 1916 eight Zeppelins reached England. One, the L.34, was shot down into the sea near Hartlepool by Second Lieutenant I. V. Pyott; another, the L.21, was hit by anti-aircraft fire and eventually fell to pieces in the air while attempting to struggle back to her home base. Thus by the end of the year the airship offensive was almost ended, although Fregatten-Kapitan Peter Strasser, the man who had done much to organise the raids on London and the provinces, could look back on a not inconsiderable achievement. Anti-aircraft guns and aeroplanes urgently needed in France had been compelled to remain in England for defence of the home front, and during the airship attacks the transport of vital raw materials and munitions had been reduced almost to a standstill. However, the actual bombing results had never really justified the expenditure on such large and vulnerable aircraft.
The Super Zeppelins, monster dirigibles powered by six engines, were the ultimate development of the airships specifically designed to attack London. When these appeared, late in 1916, the German High Command already realised that the Royal Flying Corps, the Royal Naval Air Service and the ground defences had proved the airship by no means the decisive weapon it had at first seemed. It therefore decided to reduce the number of Zeppelin raids in the future; at the same time some consideration was given to the possibility of bombing London with multi-engined aeroplanes. These raids by formations of long-range bombers were later to be surprisingly effective, and 1917 was destined to be a very successful year for many different operational units of the now highly efficient German Imperial Air Force.
