“Please express most particularly to Marshal French my thanks for services rendered on every day by the English Flying Corps. The precision, exactitude, and regularity of the news brought in by its members are evidence of their perfect organisation, and also of the perfect training of pilots and observers.” To give a rough idea of the amount of work carried out, it is sufficient to mention that, during a period of twenty days up to September 10th, a daily average of more than nine reconnaissance flights of over 100 miles each has been maintained. The constant object of our aviators has been to effect the accurate location of the enemy’s forces, and incidentally--since the operations cover so large an area--of our own units. Nevertheless, the tactics adopted for dealing with hostile aircraft are to attack them instantly with one or more British machines. This has been so far successful that in five cases German pilots or observers have been shot in the air and their machines brought to the ground. As a consequence, the British Flying Corps has succeeded in establishing an individual ascendancy which is as serviceable to us as it is damaging to the enemy. How far it is due to this cause it is not possible at present to ascertain definitely, but the fact remains that the enemy have recently become much less enterprising in their flights. Something in the direction of the mastery of the air has already been gained. The Royal Flying Corps has already won the distinction of the Legion d’Honneur. The principal uses of the new arm in war may be said to be:-- 1. Reconnaissance. 2. Directing and correcting artillery fire. 3. Offensive operations. 4. Rapid despatch carrying to a distance. 5. Distributing handbills to cities. 6. Photography. 7. Locating submarines, mines, etc. 1. _Reconnaissance._ As a particular example of the value of reconnaissance in the present war one may well refer to that mentioned in Sir John French’s first report. He says, “When the news of the retirement of the French and the heavy German threatening on my front reached me, I endeavoured to confirm it by aëroplane reconnaissance, and as a result of this I determined to effect a retirement to the Maubeuge position at daybreak on the 24th.”
