In all the war not a single battle had been fought at close quarters; there had been plenty of instances of brilliant manœuvring, of torpedo-boats running the gauntlet and hurling their deadly missiles against the sides of battleships and cruisers, and of ships rammed and sunk in a few instants by consummately-handled opponents; but the days of boarding and cutting out, of night surprises and fire-ships, had gone by for ever.

The irresistible artillery with which modern science had armed the warships of all nations had made these feats impossible, and so had placed the valour which achieved them out of court. Within the last few weeks scarcely a day had passed but had witnessed the return of some mighty ironclad or splendid cruiser, which had set out a miracle of offensive and defensive strength, little better than a floating ruin, wrecked and shattered almost beyond recognition by the awful battle-storm through which she had passed.

The magnificent armament which had held the Atlantic route had come back represented only by a few crippled ships almost unfit for any further service. True, they and those which never returned had rendered a splendid account of themselves before the enemy, but the fact remained—they were not defeated, but they were no longer able to perform the Titanic task which had been allotted to them.

So, too, with the Mediterranean fleet, which, so far as sea-fighting was concerned, had achieved the most splendid triumph of the war. It had completely destroyed the enemy opposed to it, but the victory had been purchased at such a terrible price that, but for the squadron which had come to its aid, it would hardly have been able to reach home in safety.

In a word, the lesson of the struggle on the sea had been, that modern artillery was just as effective whether fired by Englishmen, Frenchmen, or Russians; that where a torpedo struck a warship was crippled, no matter what the nationality or the relative valour of her crew; and that where once the ram found its mark the ship that it struck went down, no matter what flag she was flying.

And then, behind and beyond all that was definitely known in England of the results of the war, there were vague rumours of calamities and catastrophes in more distant parts of the world, which seemed to promise nothing less than universal anarchy, and the submergence of civilisation under some all-devouring wave of barbarism.

All regular communications with the East had been stopped for several weeks; that India was lost, was guessed by intuition rather than known as a certainty. Australia was as isolated from Britain as though it had been on another planet, and now every one of the Atlantic cables had suddenly ceased to respond to the stimulus of the electric current. No ships came from the East, or West, or South. The British ports were choked with fleets of useless merchantmen, to which the markets of the world were no longer open.

Some few venturesome craft that had set out to explore the now silent ocean had never returned, and every warship that could be made fit for service was imperatively needed to meet the now inevitable attack on the shores of the English Channel and the southern portions of the North Sea. Only one messenger had arrived from the outside world since the remains of Admiral Beresford's fleet had returned from the Mediterranean, and she had come, not by land or sea, but through the air.

On the 6th of October an air-ship had been seen flying at an incredible speed across the south of England. She had reached London, and touched the ground during the night on Hampstead Heath; the next day she had descended again in the same place, taken a single man on board, and then vanished into space again. What her errand had been is well known to the reader; but outside the members of the Cabinet Council no one in England, save the King and his Ministers, knew the object of her mission.

For fifteen days after that event the enemy across the water made no sign, although from the coast of Kent round about Deal and Dover could be seen fleets of transports and war-vessels hurrying along the French coast, and on clear days a thousand telescopes turned towards the French shore made visible the ominous clusters of moving black spots above the land, which betokened the presence of the terrible machines which had wrought such havoc on the towns and fortresses of Europe.
