The influence of the aeroplane scout upon military tactics will, undoubtedly, be marked. The German school, for example, advocates a strong, determined advance—not caring so much what the precise dispositions of an enemy are, but seeking to envelop him, and deliver one quick and crushing blow. French military tactics, on the other hand, are more strategical—more prone to play a waiting, watching game, and make a master-move after the battle scheme has, to a certain extent, revealed itself. What has been called "the fog of war"—that is to say, the meagre information regarding an enemy’s movements, which is all that is available if aeroplanes are not used—suits the German method of blunt, dogged, hit-or-miss advance. Lack of information is not advantageous, on the other hand, to the carefully thought-out French strategy. What the advent of the air-scout does is to help the Commander-in-Chief, who is able to make subtle, deeply-planned moves, in which precise information is essential, and to discount a blind, crushing use of numbers. III. Other uses of the war aeroplane—Surveying—Dispatch-carrying—Directing gun-fire—Transport of staff officers. The duties so far mentioned do not, by any means, exhaust the possibilities of the war aeroplane. So far, only military reconnaissance has been touched upon. This work is, of course, of outstanding importance; but an air-corps could, during a campaign, be put to many other tasks, all of them of genuine utility. Take, for example, the work of discovering the nature of the country over which an army is about to operate. This is a task which is extremely important. But, hitherto, the process of obtaining such information has been painfully slow—painfully slow, that is, when compared with the way the aeroplane will be able to carry out the work. Here, indeed, will be an ideal opportunity for a long-distance flight. In a three-hour, non-stop journey, a machine should be able to survey at least 150 miles of country, and return with reports of the utmost value. How important this aerial survey-work will be is instanced by Major J. N. C. Kennedy, who, from his experience in the South African war, states that such disasters as Spion Kop could not have happened, if there had been aeroplanes to fly over and observe the country beforehand. Here, then, is another practical use for the aeroplane. A squadron of machines, flying ahead of an army on the march, will be able to return with accurate news as to the position of roads, railways, rivers, and bridges. Such information, received in good time, may prove of exceptional value to a Commander-in-Chief. Apart from general survey work, also, the air-corps will be able to execute highly-important orders in locating the position of an enemy’s supply trains, magazines, and depots.
