There is other important information that only the scout can obtain as when we once found a dummy trench filled with barbed wire and controlled by machine-guns. Had our men gone forward in the attack without the knowledge of this they would have jumped down into it to be massacred like rats in a trap. Machine-gun positions are also generally indistinguishable to the airman's glass or camera. I used an instrument of my own construction which would give me the map reference of any object that I observed in relation to any other two objects the position of which I knew on the map. At night I would have the two known positions marked by distinguishing lights or have colored flares sent up from them at regular intervals.
The training of our scouts is very severe. For in this work men have to have complete confidence in their own superiority to the German soldier, and must be able to depend entirely on their own resources as they generally have to work singly or in pairs. It is necessary that they be picked men with unusual keenness of observation. They are trained for work in the dark by being made to go through the ordinary soldier's exercises blindfolded. In this way they get the extra sense that a blind man has. A blind man will not put his weight onto his foot until he has felt if it is on firm ground; and by habit he does this without hesitating. Our scouts are able after a while to walk along using their eyes for observation all the time not needing to watch where they are stepping. We also train them to have complete control over their muscles and among the final tests for first-class scouts are to remain an hour without showing any movement whatsoever and to take half an hour in getting from the prone or lying position to standing upright on their feet. These two last ideas were borrowed from the Zulu who has no equal in the world in escaping observation. They are also taught many methods for finding directions as a compass is unreliable where there is so much unidentified iron lying about.
We have abundantly demonstrated in several sectors on the western front that it is always possible for properly trained men to surprise the enemy. As a matter of fact the Germans have carried out surprise raids on us, and I am quite satisfied that it is never possible completely to guard against surprise. In one sector I had trip wires in No Man's Land connected with buzzers in our own trench so arranged that I would know if there were any one out there and to within fifty yards of where they were. But this was only possible on a quiet front where there was no actual offensive taking place, and not many shells falling in No Man's Land. I even placed buttons in the German wire so as to be sure that our patrols did not just go outside our own trench and lie in a shell-hole until it was time to return, for they had to signal by pressing these buttons at intervals. They had to repair any of these wires they found severed, and this somewhat elaborate scheme was the means of our capturing some German patrols and gave us entire control of No Man's Land.
We also took advantage of every possible means to make Fritz's sentries jumpy. We would have our snipers on certain days smash all their periscopes. I myself have shot down sixty in an afternoon when the sun was shining on them. This made them afraid that they would not have any left for emergencies and gave them a wholesome respect for our shooting so that they were very shy of exposing themselves. We would also set a rifle to fire exactly into a loophole so that when it opened we had only to pull the trigger to send a bullet through the brain of the man using it. There were other dodges that it is not wise to speak of just yet.
This may be a good place to describe the two kinds of raids. In a raid with artillery support the artillery cut out a sector of the enemy trench with a "box barrage" which means that they fire on three lines of a square leaving the open side for our troops to enter. They also put a barrage on this side until the prearranged moment when the attackers go forward. This leaves the raiders to deal with the troops within that box preventing any others coming in to support them. The weakness of this method is that it lets the whole German line know what we are doing, and the raiding-party frequently gets cut up badly by the enemy's artillery when they are returning across No Man's Land.
The most successful raid is always the silent one if you have dependable troops. The chief obstacle is the enemy wire, but beforehand the artillery can cut this in many places, and machine-guns can be ranged on these gaps to prevent their being repaired. The enemy does not know, even if he suspects a raid, exactly where it will come. It is even a good idea if you only have a small party to enter one of these gaps, crawl down fifty yards inside the wire before attacking, and, when finished, come out through another gap lower down, but every man of the party needs to scout over the ground beforehand so there will be no confusion during the attack. We have carried out successful raids in this manner when none but the Germans who were attacked knew anything of what was going on until we were back in our own trenches, and rarely were there any of these who could give evidence except by means of their dead bodies. I remember that one of our men, who was champion wood-chopper of Australia before the war, drove his bayonet through a German and six inches into a hardwood beam, and as he could not withdraw it had to unship it, leaving the German stuck up there as a souvenir of his visit. Probably not another man in the army could have done it, but it no doubt added to the reputation of the Australians, as these Fritzes must have thought us a race of Samsons.
There is a strong bond between us and the airmen, and the army's pair of eyes are focussed together, for the information from both sources is co-ordinated. Our trench maps are constructed chiefly from aeroplane photographs, and it was only occasionally that some object would be seen in the photograph that could not be identified; when we scouts would have to crawl over to it and find out its family-tree.
All our intelligence officers are given schooling in aerial observation, and I have been several times over the German lines with a pilot, and have a very high admiration for these birdmen who are not merely the bravest of the brave but princes of good fellows. I had some wonderful aeroplane photographs of some of our attacks wherein I could recognize the stages of our progress, and so expert has this work become that a German soldier can hardly even brush away a fly without a permanent record of it being obtained. Probably the greater number of our aeroplanes on the battle-front are engaged in ranging for the artillery, and in actual offensive warfare, but their greatest value is in reconnoissance, and so it will always be.
"Airman" and "scout"—one flies, the other crawls, yet both seek information from the enemy, and are the twin eyes of the army. There is a romance about the work of both that attracts adventurous youth, and neither is as dangerous as it appears to a layman. In the element of the airman he is a difficult target to hit, and it is estimated that it takes thirty thousand anti-aircraft shells to bring him down. And his machine is now so perfect that peace flying will be much safer than motoring.
In No Man's Land, the hunting-ground of the scout, shells only fall by accident, and he is camouflaged to defy detection. A black crawling suit is used at night, with hood and mask, but the most important thing is to break the outline of the head, so the hood has several peaks and corners. A human head on the sky-line cannot be mistaken for anything else, except maybe a pumpkin or melon, but in these hoods it appears like a large lump of dirt, and should the scout chance to move suddenly while in such a position, the likelihood is he would be dirt in a second or so.
