Where the cavalry scout or creeping scout of days gone by could never have proved successful, the airman has easily accomplished his purpose. He has carried messages from one frontier to another in hours, when it would have taken days for a scout on horseback or on foot to have rendered the service, if they could have accomplished it at all. He has eliminated distance.
Trench warfare developed in the world-war in a way that has never before been deemed necessary or possible, but the miles of trenches which conceal the men from the fire of the enemy are plainly visible to the airmen. And armed with cameras having powerful telescopic lenses they can photograph the entire scene and send to their own military headquarters not mere indicated plans of the battle lines, but exact photographs.
The war has shown conclusively that once the formation of the battle line has been decided upon it is, in a measure, a fixture. It may be subject to rearrangement, but this is when the force of battle demands, or for strategic purposes, but such an arrangement requires a great deal of time and much work. The battle fronts on the borders of France and Belgium have ranged from 100 to nearly 300 miles in length, with nearly 3,000,000 strung out in opposing lines along the entire distance.
LIKE AN IMMENSE GRIDIRON.
The ground has been dug up and trenched until the surface of the earth looks like an immense gridiron. The soldiers almost live within the trenches and dugouts beneath the ground. Telephone and telegraph wires run through the trenches and even railroad tracks are laid so that small engines go whirring through the ditches like "dinky" locomotives in a coal mine.
And the "eyes in the skies" make it possible for the commanders to know each other's strength and the disposition of the forces at all times.
Particularly has the air scout proved valuable in enabling commanders to execute their final orders without grievous error. There is danger of possible misjudgment because of the great length of the firing lines. The airmen verify positions and make last minute reports, taking minutes to perform services that cavalry forces or other scouting parties would have taken hours or days to render.
Operated in conjunction with cavalry scouts, and motor and cycle squads, the airplane is a destruction-directing and defensive force. And it was the large fleet of aircraft that aided Germany in making such rapid advance in its drive toward Paris in the early days of the war. The scouts reconnoitering in the early dawn were able to report the situation and give the commanders time to move their forces before the Belgians and French were aware of what was being done.
Germany had probably the largest fleet of airplanes at the beginning of the conflict and is said to have possessed upward of 500, of various sorts, and this does not include the famous Zeppelins or dirigible balloons. She also had something like two dozen factories which could turn out flying machines, and had been at work on the development of her aircraft long enough to have her patterns and methods of manufacture somewhat, if not entirely standardized. During the third year of the war it was estimated that she had more than quadrupled her force of flying machines.
