The effect the enemy hopes to gain by his constant Zeppelin raids, is partly moral, partly military. To achieve the latter it is necessary that the enemy airman destroy some position or place of military importance, as a powder-factory, an arsenal, a large camp, an important railway junction, a munitions factory, a naval dockyard, an ordnance factory, or a similar area. But in very few instances have the raiding Zeppelins touched either of these places. Thus they have achieved but little military result. The moral result attempted has been to frighten and harass the inhabitants of this country until--Germany had a mental vision--they would be groveling on their knees in the dust, begging the Government to sue for peace. We have already dealt with the moral effect these raids have on their own people. By aid of lying and bombastic reports the enemy do not fail to impress--and greatly impress--neutral countries. Some readers will perhaps remember it was after a big Zeppelin raid on this country that Bulgaria joined the Central Powers. The Germans know only too well that we do not possess large airships of our own. Suppose we did; what would be the panic and consternation caused in Berlin by the appearance over that city of a squadron of British bomb-dropping Zeppelins, and how far would it go to shorten the war? During the last few months we have seen the Zeppelin in a more useful and more dangerous aspect, namely in the capacity of Naval Scout. Let us consider what are the main duties of a light-cruiser fleet at sea; they are of a very similar nature to those of the cavalry, namely to form a protective screen to the main body, and to advance as nearly as possible to the enemy to discover the exact disposition of his forces. In one word, their main duty is scouting. In this respect the enemy went one better than ourselves. He built Zeppelins, and succeeded in accomplishing with a single Zeppelin that which in former days had required a fleet of light cruisers. Without necessarily running any risk, the giant airship at a height of 10,000 feet has a view extending on a clear day to as much as thirty miles, and some three-hundred square miles of sea surface. What cruiser look-out can claim a perspective equal to that? At thirty miles, or twenty-five or even twenty, the Zeppelin pilot is well out of range of the enemy shells, and with his wireless instrument, which has another range of thirty miles, can signal to the admiral of the fleet when the enemy is yet sixty miles off. This view explains the fact why the two fleets have so seldom been at grips in the two years of war. The enemy, by means of his aerial scouts, must oft and again have been warned of the proximity of the British Fleet. The official account of the Jutland battle stated that the weather was dull and misty; hence the Zeppelins would have been unable successfully to perform their usual duties.
