That the precautions taken against Zeppelins were by no means overdone was proved by the total failure of the second aerial raid on Antwerp, in the latter part of September, when a dirigible again sailed over the city under cover of darkness. Owing to the total absence of street-lights, however, the dirigible's crew were evidently unable to get their bearings, for the half-dozen bombs that they discharged fell in the outskirts of the city without causing any loss of life or doing any serious damage. This time, moreover, the Belgians were quite prepared--the fire of their "sky artillery," guided by searchlights, making things exceedingly uncomfortable for the Germans.
I have heard it stated by Belgian officers and others that the bombs were dropped from the dirigibles by an ingenious arrangement which made the airship itself comparatively safe from harm and at the same time rendered the aim of its bombmen much more accurate. According to them, the dirigible comes to a stop--or as near a stop as possible--above the city or fortification which it wishes to attack, at a height out of range of either artillery or rifle-fire. Then, by means of a steel cable a thousand feet or more in length, it lowers a small wire cage just large enough to contain a man and a supply of bombs, this cage being sufficiently armoured so that it is proof against rifle-bullets. At the same time it affords so tiny a mark that the chances of its being hit by artillery-fire are insignificant. If it should be struck, moreover, the airship itself would still be unharmed and only one man would be lost, and when he fell his supply of bombs would fall with him. The Zeppelin, presumably equipped with at least two cages and cables, might at once lower another bomb-thrower. I do not pretend to say whether this ingenious contrivance is used by the Germans. Certainly the Zeppelin which I saw in action had nothing of the kind, nor did it drop its projectiles promiscuously, as one would drop a stone, but apparently discharged them from a bomb-tube.
Though the Zeppelin raids proved wholly ineffective, so far as their effect on troops and fortifications were concerned, the German aviators introduced some novel tricks in aerial warfare which were as practical as they were ingenious. During the battle of Vilvorde, for example, and throughout the attacks on the Antwerp forts, German dirigibles hovered at a safe height over the Belgian positions and directed the fire of the German gunners with remarkable success. The aerial observers watched, through powerful glasses, the effect of the German shells and then, by means of a large disc which was swung at the end of a line and could be raised or lowered at will, signalled as need be in code "higher--lower--right--left" and thus guided the gunners--who were, of course, unable to see their mark or the effect of their fire--until almost every shot was a hit. At Vilvorde, as a result of this aerial fire-control system, I saw the German artillery, posted out of sight behind a railway embankment, get the range of a retreating column of Belgian infantry and with a dozen well-placed shots practically wipe it out of existence. So perfect was the German system of observation and fire control during the final attack on the Antwerp defences that whenever the Belgians or British moved a regiment or a battery the aerial observers instantly detected it and a perfect storm of shells was directed against the new position.
Throughout the operations around Antwerp, the Taubes, as the German aeroplanes are called because of their fancied resemblance to a dove, repeatedly performed daring feats of reconnaissance. On one occasion, while I was with the General Staff at Lierre, one of these German Taubes sailed directly over the Hotel de Ville, which was being used as staff headquarters. It so happened that King Albert was standing in the street, smoking one of the seven-for-a-franc Belgian cigars to which he was partial.
"The Germans call it a dove, eh?" remarked the King, as he looked up at the passing aircraft. "Well, it looks to me more like a hawk."
A few days before the fall of Antwerp a Taube flew over the city in the early afternoon, dropping thousands of proclamations printed in both French and Flemish and signed by the commander of the investing forces, pointing out to the inhabitants the futility of resistance, asserting that in fighting Germany they were playing Russia's game, and urging them to lay down their arms. The aeroplane was greeted by a storm of shrapnel from the high-angle guns mounted on the fortifications, the only effect of which, however, was to kill two unoffending citizens who were standing in the streets and were struck by the fragments of the falling shells.
Most people seem to have the impression that it is as easy for an aviator to see what is happening on the ground beneath him as though he were looking down from the roof of a high building. Under ordinary conditions, when one can skim above the surface of the earth at a height of a few hundred feet, this is quite true, but it is quite a different matter when one is flying above hostile troops who are blazing away at him with rifles and machine-guns. During reconnaissance work the airmen generally are compelled to ascend to an altitude of a mile or a mile and a quarter, which makes observation extremely difficult, as small objects, even with the aid of the strongest glasses, assume unfamiliar shapes and become fore- shortened. If, in order to obtain a better view, they venture to fly at a lower height, they are likely to be greeted by a hail of rifle fire from soldiers in the trenches. The Belgian aviators with whom I talked assured me that they feared rifle fire more than bursting shrapnel, as the fire of a regiment, when concentrated even on so elusive an object as an aeroplane, proves far more deadly than shells.
The Belgians made more use than any other nation of motor-cars. When war was declared one of the first steps taken by the military authorities was to commandeer every motor-car, every motor-cycle and every litre of petrol in the kingdom. As a result they depended almost entirely upon motor-driven vehicles for their military transport, which was, I might add, extremely efficient. In fact, we could always tell when we were approaching the front by the amazing number of motor-cars which lined the roads for miles in the rear of each division.
Anything that had four wheels and a motor to drive them--diminutive American run-abouts, slim, low-hung racing cars, luxurious limousines with coronets painted on the panels, delivery-cars bearing the names of shops in Antwerp and Ghent and Brussels, lumbering motor-trucks, hotel omnibuses--all met the same fate, which consisted in being daubed with elephant-grey paint, labelled "S.M." (Service Militaire) in staring white letters, and started for the front, usually in charge of a wholly inexperienced driver. It made an automobile lover groan to see the way some of those cars were treated. But they did the business. They averaged something like twelve miles an hour--which is remarkable time for army transport-- and, strangely enough, very few of them broke down. If they did there was always an automobile des reparations promptly on hand to repair the damage. Before the war began the Belgian army had no army transport worthy of the name; before the forts at Liege had been silenced it had as efficient a one as any nation in Europe.
The headquarters of the motor-car branch of the army was at the Pare des Automobiles Militaires, on the Red Star quays in Antwerp. Here several hundred cars were always kept in reserve, and here was collected an enormous store of automobile supplies and sundries. The scene under the long, low sheds, with their corrugated-iron roofs, always reminded me of the Automobile Show at Olympia. After a car had once been placed at your disposal by the Government, getting supplies for it was merely a question of signing bons. Obtaining extra equipment for my car was Roos' chief amusement. Tyres, tools, spare parts, horns, lamps, trunks--all you had to do was to scrawl your name at the foot of a printed form and they were promptly handed over. When I first went to Belgium I was given a sixty horse-power touring car, and when the weather turned unpleasant I asked for and was given a limousine that was big enough to sleep in, and when I found this too clumsy, the commandant of the Parc des Automobiles obligingly exchanged it for a ninety horse-power berline. They were most accommodating, those Belgians. I am sorry to say that my berline, which was the envy of every one in Antwerp, was eventually captured by the Germans.
