AS soon as the first pitched battle in the world-war was over, a lengthy and detailed report of the attack on Kerguelen and its repulse was drawn up by Alan, Captain Ernstein, and Admiral Forrest for presentation to the Council. To this report Alan added a supplement, which is here reproduced in his own words.

“From what I know of the designs of Olga Romanoff and her advisers I am convinced that the defeats which have been inflicted upon them will merely have the effect of checking, and not putting a stop to, their operations against the peace and freedom of the world.

“I have seen and heard enough during the last five years to feel satisfied that there exists a very widespread conspiracy, the object of which is the restoration of the Romanoff dynasty, in the person of Olga, the breaking up of the Anglo-Saxon Federation, and the inauguration of an era of personal despotism and popular slavery.

“As far as we have been able to learn, this conspiracy embraces practically all the descendants of those families who lost their rank, official position, or property during the reconstitution of Russia after the fall of the Romanoffs. These people have, of course, everything to gain and not much to lose by the destruction of the present order of things, and Olga has promised them, no doubt quite sincerely, that in the event of her triumph they shall be restored to all that their ancestors lost.

“As a matter of fact, the greater part of Russia will be divided amongst them should she ever accomplish her designs. The old order of things, as it existed before the days of Alexander II., is to be completely reinstated. The lower orders of the people are to be reduced once more to serfdom, and the trading classes to a condition very little better.

“If they resist they are to be terrorised into submission by the air-ships, and all who raise their voices for freedom are to be banished to Siberia, which is once more to be the prison-land of the Russian Empire. A large standing army is to be kept constantly on the war-footing, while the sea navy and the aerial fleet are to be kept up to such a strength as to be able to hold the rest of the Continent in practical subjection.

“In short, Olga aspires to nothing less than the throne of an empire which shall stretch from the Yellow Sea to the Atlantic Ocean. I am afraid, too, that there can be no doubt but that this conspiracy is not only favoured, but actually assisted, by large numbers of people throughout the Federation area.

“In fact, during the latter part of our stay at Mount Terror, the stronghold was visited by men of all nations, who, of course, came and went away in the submarine vessels, and who openly promised to do everything they could to further what they called the cause of the New Revolution in their own countries, on the understanding that the old evils of capitalism and private ownership of land by which their ancestors had grown wealthy are to be restored.

“This will, I trust, be enough to show you that the triumph of Olga Romanoff means nothing less than the complete undoing of all the work that was done in the days of the Terror.

“We have proved so far that Kerguelen, and, therefore, Aeria, is impregnable to attack save by surprise, which will now, of course, be impossible. But, on the other hand, the force at the disposal of Olga and her allies is still so strong that all our present resources will have to be kept constantly employed to protect ourselves, and this leaves the world at the mercy of any Power which can obtain the assistance of the Russians’ aerial navy, which still numbers twenty-seven vessels, all equal to our best ships.

“In addition to these they possess a submarine navy of at least forty vessels, all of which are swifter and more powerful than ours, with the exception of the Narwhal. I therefore suggest that the whole of the resources at the command of the Council shall at once be devoted to the building of at least fifty air-ships of the Ithuriel type, and the same number of submarine battleships like the Narwhal, complete plans of which I enclose.

“Until this additional force is at our command, I think it would be useless to attempt the destruction of the Russian stronghold in Antarctica, and until this is destroyed there can be no hope of peace. This stronghold, which I will now attempt to describe for the information of the Council, is one of the most marvellous places on earth.

“It lies in and about Mount Terror and the Parry Mountains, which run from it towards the pole behind the ice-barrier of Antarctica. Nearly ten years ago a Russian explorer named Kishenov reached the ice-barrier and made the discoveries which have enabled the Russian revolutionists to create their stronghold. In addition to his ship, he took with him three aerostats, which were chiefly constructed during his voyage, and also a small submarine vessel, which he took out in sections and put together at sea.

“He skirted the coast of Victoria Land, and was stopped by the ice in latitude 78°, as all other Antarctic explorers by sea have been since the voyage of Sir James Ross. The season was a singularly fine and open one, and two days after his arrival he inflated one of his aerostats and crossed the great barrier, to make a thorough exploration of the unknown land. Kishenov was the first man, not an Aerian, who had ever seen what there was on the other side of the Antarctic ice-wall.

“But he discovered far more than our explorers did, for while he was in the neighbourhood of Mount Terror an earthquake, accompanying a violent eruption of Mount Erebus, made a huge fissure in the south side of Mount Terror. After waiting three days to make sure that the earthquake had subsided, he and two of his officers entered the crevice, which they found to be over two hundred feet wide at the level of the land ice.

“Furnished with storage batteries and electric lights, they penetrated into the interior of the mountain and found that it was pierced in all directions with great galleries and enormous chambers, hollowed out by volcanic forces during the period of Mount Terror’s activity. Four days were spent altogether in exploring this subterranean region, the existence of which was kept a profound secret by Kishenov and his officers.

“Not the least strange and, as it has proved, one of the most valuable portions of his discovery was the finding of a subterranean lake in the heart of Mount Terror, the temperature of which was kept far above the freezing point by the heat which the interior of the mountain derived from the neighbouring fires of Mount Erebus. Finding the lake to be salt water, he concluded that it must have some connection with the open sea, and so the next day he and the same two officers entered the submarine boat and penetrated underneath the ice-barrier.

“After a search of five hours, the search-lights of the boat revealed a huge tunnel leading south-west into the land, that is to say, direct for Mount Terror. They followed this tunnel up for a distance of nearly five miles, and then struck the end. They now rose, and finally found themselves floating on the surface of the lake in the interior of the mountain.

“One of Kishenov’s officers, a man named Louis Khemski, was a member of the Russian Revolutionary Society, whose existence only became known five years ago. After the capture of the Ithuriel the heads of this society met, and to them this man communicated the secret of Mount Terror. Kishenov and the other officer refused to join the revolutionists, and were assassinated.

“Khemski was at once taken on board the Ithuriel, now renamed the Revenge, and guided her to the fissure leading into Mount Terror. Its outer portion was of course filled and covered with ice and snow, but as soon as Khemski had found its position by his landmarks, a couple of shells speedily reopened it, and it was here that the Revenge lay hidden while you were ransacking the world for her.

“Olga inherited from her grandfather, the father of the Vladimir Romanoff who was executed for disobeying the order of the Council, all the plans and directions necessary for the building both of air-ships and submarine vessels, and as soon as this perfect stronghold and hiding-place was discovered, her accomplices in the conspiracy for the restoration of the Russian monarchy at once devoted their fortunes to the supply of money and materials. The Revenge made one more voyage to Russia, and by travelling at full speed at a great elevation managed to make it unobserved.

“The services of the cleverest engineers and most skilful craftsmen among the revolutionists were secured. Transports were chartered and sent out to Antarctica loaded with materials. On the shores of the subterranean lake the first squadron of submarine vessels was built, and then began the system of ocean terrorism which soon paralysed the trade of the world.

“Piracy was carried on with utter ruthlessness. Transports were sunk by the vessels, and then plundered by divers of the treasure which they carried, and which was employed to purchase new materials and to repay those who had furnished the first funds.

“Alexis and myself were kept by Olga, as I said in my first letter, under the influence of a drug which completely paralysed our volitional power, and were compelled to reveal all we knew concerning our own air-ships, submarine vessels, guns, and explosives. And in this manner was created and equipped the force which will be employed to dispute with us the empire of the world unless we are able to extirpate it utterly.”

While the despatch to the Council was being drawn up, the Narwhal had been lying in the inner basin of Christmas Harbour, renewing her store of motive power from the generating station ashore. As soon as the engineer in charge reported that her power-reservoirs were full, and Alan had delivered the despatch for conveyance to Aeria by air-ship, Alexis, who had been apparently buried in a brown study for the last two hours or so, asked Alan to come with him into his private cabin, and as soon as the two friends were alone together he said to him—

“Look here, old man! While you fellows have been drawing up that despatch, and talking about the impossibility of attacking the stronghold at Mount Terror, I’ve been doing some thinking, and I’ve come to the conclusion that as far as an under-sea attack is concerned, it isn’t quite so hopeless as you’ve made out.”

“I shall be only too delighted to hear you prove us wrong,” replied Alan, his eyes brightening at the prospect, for he knew Alexis too well not to be sure that he would not have spoken in this way unless he had pretty solid reasons for doing so. “Say on, my friend; I am all attention.”

“Get out to sea, then, as fast as ever you can,” said Alexis, “for there’s not an hour to be lost if you adopt my plan, and if you don’t we can just come back.”

“Very well,” said Alan. “What’s the course?”

“Clear the islands and head away southward as hard as you can go,” replied Alexis briefly.

The excitement of the battle in which he had played such a terrible part had left Alan in just the frame of mind to listen to the project of a desperate adventure, such as he instinctively knew was now in his friend’s mind. Without hesitating further he went into the saloon, summoned the crew of the Narwhal, and said to them—

“Alexis and I have decided upon an enterprise which will end either in very great injury to our enemies or our own destruction. You have seen enough to-day to know that in the warfare we are engaged in there are only two choices: victory or destruction. We don’t want to take anyone against his will to what may be certain death. Those who care to go ashore may do so.”

Not a man moved. An athletic sailor named George Cosmo, who held the post of chief engineer, saluted, and said briefly—

“We shall all go, sir. What are the orders?”

“Get out of the harbour as fast as you can, and as soon as you are clear of the islands sink two fathoms, steer a straight course due south-east, and put her through the water as hard as she’ll go,” replied Alan.

Cosmo saluted again, and left the room with his comrades to execute the order.

“Now, my friend,” said Alan, turning to Alexis as soon as they were alone again, “what is your plan?”

“Simply this,” replied Alexis. “Mount Terror, or at any rate the mouth of the submarine tunnel, is in round numbers three thousand geographical miles from here. Our speed is thirty miles an hour faster than that of Olga’s squadron. That means that even if they go back at once and at full speed we shall be there four or five hours before them.

“They, I think, have had quite enough fighting for to-day, and I don’t believe they’ll attack the island again—first, because they know that they can’t take our sea defences by surprise, and, second, because they think the Narwhal will remain on guard.

“Either they will go off on a raiding expedition somewhere else with the air-ships—in which case we can’t follow them, for we don’t know where they’re going—or they will return to Mount Terror at an easy speed of fifty or sixty miles an hour. They will never dream that you and I will venture to attack the stronghold single-handed, and, therefore, that is just what I propose to do.”

“That will be odds of about forty to one against the Narwhal,” replied Alan, somewhat gravely. “Unless we can destroy it completely before they get back. But go on. Let’s hear the rest. I don’t think you can propose anything too desperate for me now that I have really tasted the blood of the enemy.”

“Well, what I propose is not to destroy the stronghold, simply because it would be impossible to do that by sea. I merely propose to get quietly into the tunnel, go to that narrow part about two miles from the entrance, fix a dozen torpedoes with time-fuses up against the roof of the tunnel, and then clear out into the open water.

“When those twelve torpedoes go off if they don’t bring a few thousand tons of rock down into the tunnel and block it pretty securely I’ll grant I know very little about explosives.”

“Good so far, very good!” said Alan. “I confess I envy you that idea. What next?”

“Well, after that,” replied Alexis. “You see we shall have shut in the vessels that are inside and shut out those that are outside. The ones inside will be no use for some time, for it will take the divers a good many days to open the tunnel again, even if they ever do.

“As for those outside, we can lie in wait for them if they return, and trust to the Narwhal’s speed and strength to sink as many of them as we can, or else, if they don’t put in an appearance, we can come home with the consciousness that we have done about all the damage in our power. Now, what do you think?”

Alan was silent for a few moments, weighing the pros and cons of the desperate venture—for desperate it was, in spite of the incomparable speed and strength of the splendid vessel he commanded.

It was easy enough, always supposing that it could be accomplished without interruption; but to be caught in the tunnel, as was quite possible, between a force inside and one outside meant almost certain destruction, for if the Narwhal was not rammed and sunk in a space too narrow for her to turn she would be certain to be blown up by the torpedoes which would be launched against her.

In the end, the very character of the desperate venture, combined with the magnitude of the injury it would do to the enemy, overcame the scruples of his prudence. He put his hand on Alexis’ shoulder, and giving him a gentle shake, said with a laugh—

“Bravo, old philosopher! You’ve done more with your thinking than we have with our talking and writing. We’ll do it, if there isn’t a square foot of the Narwhal left when the business is over.”

“I knew you’d say that,” said Alexis. “Now let’s have some dinner and go to sleep, for we shall want it.”

It was then very nearly midday, and the Narwhal had cleared the islands, and, with her prow pointed direct for the north-eastern extremity of Wilkes’s Land, was rushing at full speed through the water about twelve feet below the surface of the sea. For twenty hours she sped silently and swiftly and unseen on her way, swept round the ice-barrier that fences the northern promontory of Victoria Land and into the bay dominated by the fiery crest of Mount Erebus.
