This rapid summary may serve to show how Farnborough, at the outbreak of war, was a generating centre for the air forces of the British Empire, and how, until the Germans were held in France, all other purposes had to be postponed.

Official returns show that with the four squadrons there went to France 105 officers, 755 other ranks, 63 aeroplanes, and 95 mechanical transport vehicles. At home there remained 41 officers, 116 aeroplanes, and 23 mechanical transport vehicles. But these latter figures are misleading. All the experienced officers at home were fully employed on necessary work, and the hundred and sixteen aeroplanes were impressive only by their number. About twenty of them, more or less old-fashioned, were in use at the Central Flying School for purposes of training; the rest were worn out or broken, and were fit only for the scrap-heap. By the time that the war was a month old, the efficiency of the machines which had gone abroad was threatened by the progress of events at the front. The B.E. 2, which was generally reckoned the best of these machines, had been designed for the purposes of reconnaissance; it had a fair degree of stability, and gave the observer a clear view around him and beneath him. So long as it was not interfered with in the air it was an admirable machine for the reconnoitring of enemy dispositions and movements. But the process of interference had begun. During the months of October and November fighting in the air became fairly frequent. This fighting had been foreseen, but only as a speculative possibility. Major-General Seely, speaking on the Air Estimates for 1919-20, told the House of Commons that he had witnessed the first air combat in France, one of those referred to in Sir John French's first dispatch, and that Sir David Henderson had said to him: 'This is the beginning of a fight which will ultimately end in great battles in the air, in which hundreds, and possibly thousands, of men may be engaged at heights varying from 10,000 to 20,000 feet.'

A call for fighting machines soon followed these early combats. On the 4th of September 1914 General Henderson wired home: 'There are no aeroplanes with the Royal Flying Corps really suitable for carrying machine-guns; grenades and bombs are therefore at present most suitable. If suitable aeroplanes are available, machines-guns are better undoubtedly. Request you to endeavour to supply efficient fighting machines as soon as possible.' A day or two earlier a request had been sent home for nine aeroplanes to replace losses, and for a complete new set of reserve aeroplanes for the Aircraft Park.

War is the only adequate training for war, and it was the necessities of the war which revealed the needs of the Flying Corps, and gradually, by hard-won experience, determined the best types of aeroplane and the best kinds of armament. The enemy, driving with all his might for speedy victory, allowed no holiday for research and manufacture. What hope was there that the handful of officers in charge of the few centres of military aeronautics in England would be able to meet the growing needs of the campaign in France? The outbreak of war found this country practically without an aeroplane engine industry. The few British firms who understood anything about aeroplane manufacture had in time of peace received only small experimental orders, and so were not organized for rapid production. The situation might well be called desperate. How could trained pilots, and machines fit to hold their own in the air, be produced in sufficient numbers to secure for us not the mastery of the air—that was too distant a goal—but the power to keep the air, and to give much-needed assistance to the British army in France?

No one knows what he can do until he tries. If the situation was desperate, it was also familiar. The English temper is at its best in desperate situations. The little old army held the pass in France and Flanders against enormous odds, and so procured time for the building up of the New Army, the instrument of victory. The Royal Flying Corps, a small body of highly trained men, kept the air in France, alongside of the splendid French air service, while a new and greater air force was brought to birth at home. The creation of this new force was of a piece with that wonder of the war—the creation of the New Army. In some ways it was the most difficult part of that great achievement. The new infantry battalions were made largely by the imitation of a magnificent model and the repetition of methods proved by many past successes. The men who brought the Flying Corps to an unexpected strength had to explore untried ways; the problems presented to them were complicated and novel; they had no safe models to copy, and no ancient tradition to follow. They had to cope patiently and resolutely with the most recent of sciences, and, more than that, they had to procure and train a body of men who should transform the timid and gradual science into a confident and rapid art. The engine is the heart of an aeroplane, but the pilot is its soul. They succeeded so well that at the opening of the battles of the Somme, on the 1st of July 1916, the Royal Flying Corps held the mastery of the air, that is to say, they held a predominant position in the air, and were able to impose their will upon the enemy. At the date of the armistice, the 11th of November 1918, the united Royal Air Force was incomparably the strongest air force in the world. Most of the pilots and observers who were flying at that time are now scattered in civil employ, but they will never forget the pride of their old allegiance nor the perils and raptures of their old life in the air.

It is the business of this history to tell of their doings. But before recording the appearance at the front of squadron after squadron, it is essential to tell something of the making of these squadrons. The whole elaborate system which was the basis of the Royal Air Force, the production of machines and armament and the training of men, was devised and put in action during the first year of the war. It was elastic in character, and was capable of great expansion, but its main outlines were never changed, even when the Royal Flying Corps and the Royal Naval Air Service, after a divorce of four years, were reunited in 1918. Englishmen are much in the habit of decrying their own achievements. This they do, not from modesty, but from a kind of inverted pride. Even a fair measure of success seems to them a little thing when it is compared with their own estimate of their abilities. Before the war the German power of organization was tediously praised in England, and our own incapacity for organization was tediously censured. There is truth in the contrast; the Germans love organization and pattern in human society, both for their own sake and for the rest and support that they give to the individual. The British hate elaborate organization, and are willing to accept it only when it is seen to be necessary for achieving a highly desired end. With the Germans, the individual is the servant of the society; with us, the society is the servant of the individual, and is judged by its success, not only in promoting his material welfare, but in enhancing his opportunities and giving free play to his character. We do not readily organize ourselves except under the spur of immediate necessity. But those of us who are honest and frank will never again say that we cannot organize ourselves. The making of our air force was a masterpiece of organization. The men who achieved it have earned a place in the memory of their country.

When military aviation had outgrown its early pupilage to the Royal Engineers it came under the immediate control of the War Office. It was dealt with at first by the small committee, under Brigadier-General Henderson, which had prepared the plans for the formation of the Flying Corps, and which was continued in being after the Flying Corps was formed. In November 1912 Captain E. L. Ellington, of the Royal Artillery, succeeded Major MacInnes as secretary to this committee; in June 1913 the committee was dissolved, and its work was taken over by a newly formed section of the Military Training Directorate, with Captain Ellington in charge. A little later, on the 1st of September 1913, a Military Aeronautics Directorate was established in the War Office, and at once took charge of the military air service. It was independent of the four great departments of the War Office, and the Director-General of Military Aeronautics dealt in person with the Secretary of State for War. There were three sections or branches (officially called subdivisions) of the directorate. The first of these was responsible for general policy, administration, and training. The second was responsible for equipment—the provision and inspection of material. The third had charge of contracts. It was a new departure to place a contracts branch under the control of a military director-general, but aviation is a highly technical business, and the arranging of contracts for aircraft and air engines could not be profitably separated from the other aspects of the work. In immediate touch with the directorate, and completing the original organization of military aeronautics, there were the Central Flying School at Upavon, the Military Wing of the Royal Flying Corps with its eight authorized squadrons, the Royal Aircraft Factory, and the Aeronautical Inspection Department.

In July 1914 Brigadier-General Sir David Henderson was Director-General of Military Aeronautics; Captain Godfrey Paine, R.N., was Commandant of the Central Flying School; and Lieutenant-Colonel F. H. Sykes was the Officer Commanding the Military Wing. When the war broke out Sir David Henderson was appointed to command the Royal Flying Corps in the field, with Lieutenant-Colonel F. H. Sykes as his Chief of Staff.

Thus, at a time when rapid development was essential if we were to hold the air, the two most important officers, who had nursed the Flying Corps from its infancy, were called away to more urgent service. General Henderson still held his directorship of military aviation. If he thought the war likely to be short, he was not alone in that belief. Major Burke's squadron, when they left their quarters at Montrose, fastened up the doors of their rooms with sealing-wax and tape, and affixed written instructions that nothing was to be disturbed during their absence. Meantime, the duties of the directorate and of the home command of the Flying Corps had to be carried on, at high pressure, in the face of enormous difficulties. The practical work of the directorate was undertaken by the little group of staff officers who were familiar with it, and especially by Major W. S. Brancker, who, on the outbreak of war, was appointed an Assistant Director of Military Aeronautics, and soon after became Deputy Director. The command of the Military Wing at Farnborough was given to Major Hugh Montague Trenchard, and the Royal Flying Corps had found its destined Chief.

'We should be modest for a modest man,' Charles Lamb somewhere remarks, 'as he is for himself.' But this is no personal question. What is said of General Trenchard is said of the Flying Corps. The power which Nature made his own, and which attends him like his shadow, is the power given him by his singleness of purpose and his faith in the men whom he commands. He has never called on them to do anything that he would not do himself, if he were not very unfortunately condemned, as he once told the pilots of a squadron, to go about in a Rolls-Royce car and to sit in a comfortable chair. He has never thought any deed of sacrifice and devotion too great for their powers. His faith in them was justified. Speaking, in 1918, to a squadron of the Independent Force, newly brought to the neighbourhood of Nancy for the bombing of the munition factories of Germany, he reminded them that if sending them all at once across the lines, never to return, would shorten the war by a week, it would be his duty to send them. The pilots listened to him with pride. He had their confidence, as they had his. 'Don't cramp the pilots into never talking,' is one of his advices to commanders, and the system whereby the pilots and observers, returning dazed and exhausted from a raid or a fight in the air, were brought to the office of the aerodrome and encouraged by sympathetic questions to tell what they had seen and done, was a system which grew up at once under his command. His intuitive understanding of the men who served under him, his quickness in learning the lessons of experience, and his resourcefulness and daring in immediately applying these lessons for the bettering of the Flying Corps, have been worth many brigades to his country. His name will occur often in this record, but here, at his first entry, he must be introduced to the reader.
