The Angel of the Revolution Part 30

The captain of the _Ariel_ bowed in reply, and stamped thrice on the deck. The fan-wheels whirled round, and the air-ship rapidly ascended, at the same time moving diagonally across the quadrangle of the a.r.s.enal.

Scarcely had she reached the other side when there was a tremendous explosion in the north-eastern angle of the building. A sheet of flame shot up through the roof, the walls split asunder, and ma.s.ses of stone, wood, and iron went flying in all directions, leaving only a fiercely burning ma.s.s of ruins where the gable had been.

The Professor turned ashy pale, staggered backwards with both his hands clasped to his head, and gasped out brokenly as he stared at the conflagration--

"G.o.d have mercy on me! My laboratory! My a.s.sistant--I told him"--

"What did you tell him, Professor?" said Mazanoff sternly, grasping him suddenly by the arm.

"I told him not to open the other cylinder."

"And he has done so, and paid for his disobedience with his life,"

said Mazanoff calmly. "Console yourself, my dear sir! He has only saved me the trouble of destroying your laboratory. I serve a sterner and more powerful master than yours. He ordered me to make your experiments impossible if it cost a thousand lives to do so, and I would have done it if necessary. Rest content with the knowledge that you have saved, not only the rest of the a.r.s.enal, but also Petersburg, by your surrender; for sooner than that secret had been revealed, we should have laid the city in ruins to slay the man who had discovered it."

The prisoner of the Terrorists made no reply, but turned away in silence to watch the rapidly receding building, in the angle of which the flames were still raging furiously. A few minutes later the _Ariel_ had rejoined her consorts. Her captain at once went on board the flagship to make his report and deliver up his prisoner to Natas, who looked sharply at him and said--

"Professor, will you give me your word of honour to attempt no communication with the earth while it may be found necessary to detain you? If not, I shall be compelled to keep you in strict confinement till it is beyond your power to do so."

"Sir, I give you my word that I will not do so," said the Professor, who had now somewhat regained his composure.

"Very well," replied Natas. "Then on that condition you will be made free of the vessel, and we will make you as comfortable as we can.

Captain Arnold, full speed to the south-westward, if you please."

CHAPTER XXVIII.

A SKIRMISH IN THE CLOUDS.

A few minutes after two on the following morning, that is to say on the 28th, the electric signal leading from the conning-tower of the _Ithuriel_ to the wall of Arnold's cabin, just above his berth, sounded. As it was only permitted to be used on occasions of urgency, he knew that his presence was immediately required forward for some good reason, and so he turned out at once, threw a dressing-gown over his sleeping suit, and within three minutes was standing in the conning-tower beside Andrew Smith, whose watch it then happened to be.

"Well, Smith, what's the matter?"

"Fleet of war-balloons coming up from the south'ard, sir. You can just see 'em, sir, coming on in line under that long bank of cloud."

The captain of the _Ithuriel_ took the night-gla.s.ses, and looked eagerly in the direction pointed out by his keen-eyed c.o.xswain. As soon as he picked them up he had no difficulty in making out twelve small dark spots in line at regular intervals sharply defined against a band of light that lay between the earth and a long dark bank of clouds.

It was a division of the Tsar's aerial fleet, returning from some work of death and destruction in the south to rejoin the main force before Berlin. Arnold's course was decided on in an instant. He saw a chance of turning the tables on his Majesty in a fashion that he would find as unpleasant as it would be unexpected. He turned to his c.o.xswain and said--

"How is the wind, Smith?"

"Nor'-nor'-west, with perhaps half a point more north in it, sir.

About a ten-knot breeze--at least that's the drift that Mr. Marston's allowing for."

"Yes, that's near enough. Then those fellows, if they are going full speed, are coming up at about twenty miles an hour, or not quite that. They're nearly twenty miles off, as nearly as I can judge in this light. What do you make it?"

"That's about it, sir; rather less than more, if anything, to my mind."

"Very well, then. Now signal to stop, and send up the fan-wheels; and tell the _Ariel_ and the _Orion_ to close up and speak."

"Ay, ay, sir," said the c.o.xswain, as he saluted and disappeared.

Arnold at once went back to his cabin and dressed, telling his second officer, Frank Marston, a young Englishman, whom he had chosen to take Mazanoff's place, to do the same as quietly as possible, as he did not wish to awaken any of his three pa.s.sengers just at present.

By the time he got on deck the three air-ships had slowed down considerably, and the two consorts of the _Ithuriel_ were within easy speaking distance. Mazanoff and Tremayne were both on deck, and to them he explained his plans as follows--

"There are a dozen of the Tsar's war-balloons coming up yonder to the southward, and I am going to head them off and capture the lot if I can. If we can do that, we can make what terms we like for the surrender of the _Lucifer_.

"You two take your ships and get to windward of them as fast as you can. Keep a little higher than they are, but not much. On no account let one of them get above you. If they try to descend, give each one that does so a No. 1 sh.e.l.l, and blow her up. If one tries to pa.s.s you, ram her in the upper part of the gas-holder, and let her down with a smash.

"I am going up above them to prevent any of them from rising too far.

They can outfly us in that one direction, so I shall blow any that attempt it into little pieces. If you have to fire on any of them, don't use more than No. 1; you'll find that more than enough.

"Keep an eye on me for signals, and remember that the whole fleet must be destroyed rather than one allowed to escape. I want to give the Tsar a nice little surprise. He seems to be getting a good deal too c.o.c.k-sure about these old gas-bags of his, and it's time to give him a lesson in real aerial warfare."

There was not a great newspaper in the world that would not have given a very long price to have had the privilege of putting a special correspondent on the deck of the _Ithuriel_ for the two hours which followed the giving of Arnold's directions to his brother commanders of the little squadron. The journal which could have published an exclusive account of the first aerial skirmish in the history of the world would have scored a triumph which would have left its compet.i.tors a long way behind in the struggle to be "up to date."

As soon as Arnold had given his orders, the three air-ships at once separated. The _Ariel_ and the _Orion_ shot away to the southward on only a slightly upward course, while the _Ithuriel_ soared up beyond the stratum of clouds which lay in thin broken ma.s.ses rather more than four thousand feet above the earth.

It was still rather more than an hour before sunrise, and, as the moon had gone down, and the clouds intercepted most of the starlight, it was just "the darkest hour before the dawn," and therefore the most favourable for the carrying out of the plan that Arnold had in view.

Shortly after half-past two he knocked at Natasha's cabin-door, and said--

"If you would like to see an aerial battle, get up and come into the conning-tower at once. We have overtaken a squadron of Russian war-balloons, and we are going either to capture or destroy them."

"Glorious!" exclaimed Natasha, wide awake in an instant at such startling news. "I'll be with you in five minutes. Tell my father, and please don't begin till I come."

"I shouldn't think of opening the ball without your ladyship's presence," laughed Arnold in reply, and then he went and called Natas and his attendant and the Professor before going to the conning-tower, where in a very few minutes he was joined by Natasha.

The first words she said were--

"I have told Ivan to send us some coffee as soon as he has attended to my father. You see how thoughtful I am for your creature comforts.

Now, where are the war-balloons?"

[Ill.u.s.tration: "Come now, and fire the first shot in the warfare of the future."

_See page 211._]

"On the other side of those clouds. There, look down through that big rift, and you will see one of them."

"Why, what a height we must be from the earth! The balloon looks like a little toy thing, but it must be a great clumsy contrivance for all that."

"The barometer gives five thousand three hundred feet. You will soon see why I have come up so high. The balloons can rise to fifteen or twenty thousand feet, if they wish to, and in that way they could easily escape us; therefore, if one of them attempts to rise through those clouds, I shall send him back to earth in little bits."

"And what are the other two air-ships doing?"

"They are below the clouds, heading the balloons off from the Russian camp, which is about fifty miles to the north-westward. Ha! look, there go the searchlights!"

As he spoke, two long converging beams of light darted across a broad s.p.a.ce of sky that was free from cloud. They came from the _Ariel_ and the _Orion_, which thus suddenly revealed themselves to the astonished and disgusted Russians, one at each end of their long line, and only a little more than half a mile ahead of it.
