It was the old, old story, the story of every war that England had gone into and "muddled through" somehow; but with two differences. Her soldiers had never had to fight an enemy in the skies before, and—there was no time now to straighten out the muddle, even if every able-bodied man in the United Kingdom had been trained soldiers, as the invaders were.

But there was another element in the situation. Incredible as it might seem to those ignorant of the tremendous forces brought into play, the home fleets of Europe had been destroyed, practically to a ship, within three days and nights. The narrow seas were deserted. On the morning of the seventeenth, four transports attempting to cross from Hamburg to Ramsgate, carrying a force of men, horses and light artillery, which was intended to operate as a flying column along the northern shores of Kent, had been rammed and sent to the bottom within fifteen minutes half way between land and land, and not a man nor an animal had escaped.

There was no news from the expeditions which had been sent against Hull and Newcastle—all the cables had been cut, save the transatlantic lines, the cutting of which the United States had already declared they would consider as an unfriendly act on the part of the Allies, and the British cable from Gibraltar to the Lizard which connected with Palermo and Rome, and so formed the link of communication between Britain and the Mediterranean.

The British Mediterranean Fleet was coming home, so were the West Indian and North American squadrons, while the squadron in the China seas was also ordered home, via the Suez Canal, to form a conjunction with our Italian Allies. Of course, these ships would in due time be dealt with by the aërial submarines, but meanwhile commerce with Europe had become impossible. Imports had stopped at most of the great ports through sheer terror of this demon of the sea, which appeared to be here, there and everywhere at the same time; and with all these powerful squadrons converging upon the shores of Britain the problem of feeding and generally keeping fit for war some three millions of men and over half a million horses would soon begin to look distinctly serious.

Castellan's vessels had hunted in vain for this solitary vessel, which single-handed, marvellous as it seemed, kept the narrow waters clear of invaders. The truth of this matter, however, was very simple. The Ithuriel was nearly twice as fast in the water as the Flying Fishes, and she carried guns with an effective range of five miles, whereas they only carried torpedoes.

For instance, during the battle of Sheerness, in which the remaining units of the North Sea Squadron had, with the Ithuriel's aid, attacked and destroyed every German and Russian battleship and transport, Erskine's craft had done terrible execution without so much as being seen until, when the last of the German Coast Defence ships had gone down with all hands in the Great Nore, off the Nore lighthouse, whence she was shelling Garrison Fort, the Ithuriel had risen above the water for a few moments, and Denis Castellan had taken a cockshot with the three forward guns at a couple of Flying Fishes that were circling over the town and fort and river mouth.

The shells had time-fuses, and they were timed to the tenth of a second. They burst simultaneously over the airships. Then came a rending of the atmosphere, and descending streams of fire, which burst with a rapid succession of sharp reports as they touched the airships. Then came another blaze of light which seemed to darken the wintry sun for a moment, and then another quaking of the air, after which what was left of the two Flying Fishes fell in little fragments into the water, splashing here and there as though they had been shingle ballast thrown out of a balloon.

True, Garrison Fort had been blown up by the aërial torpedoes, and the same fate was befalling the great forts at Tilbury, but their gallant defenders did not die in vain, and, although the remainder of the aërial squadron were able to go on and do their work of destruction on London, whither the Ithuriel could not follow them, the wrecks of six battleships, a dozen destroyers and ten transports strewed the approaches to the Thames and the Medway, while nearly thirty thousand soldiers and sailors would never salute the flag of Czar or Kaiser again.

In all the history of war no such loss of men, ships and material had ever taken place within the short space of three days and a few hours. Four great fleets and nearly a hundred thousand men had been wiped out of existence since the assault on Southern England had begun, and even now, despite the airships, had the millions of Britain's able-bodied men, who were grinding their teeth and clenching their fists in impotent fury, been trained just to shoot and march, it would have been possible to take the invaders between overwhelming masses of men—who would hold their lives as nothing in comparison with their country's honour—and the now impassable sea, and drive them back into it. But although men and youths went in their tens of thousands to the recruiting stations and demanded to be enlisted, it was no use. Soldiers are not made in a day or a week, and the invaders of England had been making them for forty years.
