Upon their arrival in the palace, Robert and his companions found the royal household in an uproar. The emperor’s army, vastly superior in numbers and weapons, had already fought its way round two sides of the city and was fast surrounding it. Striking with unexpected promptness, and transported swiftly the greater part of the distance by rail, the advance forces had appeared before the city shortly after the Sphere’s departure for the pole. Thus did the emperor elect to reply to Hakon’s ultimatum. In another day the Svergadians expected to be in a state of absolute siege.
It must not be supposed that the Martians had done away with arms and soldiers, even though they enjoyed one universal government. Rebellions were not unknown, and the central government had its hands full keeping all factions quiet. Emperor Kharnov, himself a usurper, maintained a strong army, ostensibly for policing and preserving order, but in reality to protect himself against the aspirations of his numerous enemies.
With but some seventy hours of food supply within the city boundaries, the situation seemed desperate. So far, Kharnov had made no specific demands, but it was expected that the conditions which he would dictate after encircling the city would hinge upon the possession of Zola.
It was in this hour of impending disaster that Robert had greatness thrust upon him. With implicit confidence in Robert’s ability, Hakon begged him to take charge of his forces to resist the invader. Zola’s trustful belief in him and her urging decided Robert. He became chief commander of the besieged forces.
Immediately upon his appointment Robert in turn appointed Taggert as his aid and placed Professor Palmer in charge of the palace defenses. His next step was to organize an immediate surprize counter-attack upon the invaders. Though he had not slept in many hours, during which time he had endured much, Robert felt no desire for sleep. The excitement and emergency confronting him buoyed him up for the time. He refused to rest until forced to.
Another hasty ascent in the Sphere revealed to them the exact situation. The emperor’s main army had pushed northward along the fertile region of one of the two great parallel canals. It had stopped south of the metropolis, sending out smaller contingents in either direction to begin the encircling movement. This movement had already made considerable progress, encountering little resistance in the nearly deserted, small outlying towns whose loyal defenders had all rallied to Hakon’s main forces in Svergad. The right spur of the invaders had made the most progress, having succeeded in pushing more than half-way round the metropolis.
It was at this right spur that Robert decided to strike first, in an attempt to take it by surprize, cutting it off from the main army, with the hope of defeating it before the main army could come to its aid. He also planned to launch an attack simultaneously upon the main army in an effort to divert its attention from the spur.
A brief council of war with Hakon and his leaders followed, in which the exact point of attacks were determined upon. Also, orders were wired to all loyal pumping stations situated near the southern edge of the regions loyal to Hakon to shut off the water supply. This would deprive Kharnov’s supporters in the region of the equator of all water supplied by ducts leading from the northern polar cap; thus the emperor’s armies and his present supporters would soon be confronted with the difficult problem of existing without water in many regions. An ultimatum, demanding the immediate withdrawal of his forces and informing him of the discontinuance of the water supply until his retreat was well under way, was dispatched to Kharnov at once.
A system of signals from the Sphere was decided upon. It was agreed that, as a weapon of destruction and direction, the Sphere was their most powerful aid. The greatest concern was over the dwindling supply of petrol in its tanks, and the extreme difficulty which Hakon’s best chemists were having in obtaining enough of the planet’s meager supply of mineral oils to produce any quantity of this fuel. Robert was facing the alternative of either remaining to help defend Zola and her people with the possibility of never being able to return to the Earth, or of returning at once with the now barely sufficient supply of petrol to make the trip. He felt that he owed his companions the chance to decide, though he himself was determined to stand by the princess in any event.
“Old man, I’m with you to the finish. Aren’t we all partners in this adventure anyway?” was Taggert’s reply when Robert told him of their quandary.
And Professor Palmer echoed him.
Without further delay the attacks were launched. Lacking any means of observation from above, the invaders were at a disadvantage in spite of their superior numbers. The separation of the spur from the main body was accomplished as planned, and a second body of Hakon’s men striking at the head of the column of invaders completed their rout, killing many and taking the rest prisoners.
The arms captured were a welcome acquisition; but the problem of feeding several thousand prisoners was a difficult one. Fortunately, a small food supply train was captured with them. They were immediately put to work throwing up earthworks and conveying heavy equipment about.
One general and several other high officers were captured. A special guard was set over these valuable hostages, for their possession would be of advantage to Hakon when terms came to be considered.
During the attack Robert had directed his forces by means of a simple smoke tube apparatus with which the Sphere was equipped, and by means of which long or short puffs of dense black smoke were ejected by manipulation of a plunger. The smoke was produced in a small oven chamber from ignited briquettes.
As the attack progressed perfectly, Robert did not utilize the terrible destructive force of the Norrensen Tube. Owing to the small reserve of petrol and consequently of electric energy depending upon it, he decided to withhold all knowledge of this weapon from their enemies until a particularly opportune time for its use presented itself. The enemy was not so considerate of him, however. Several times projectiles fired by their artillery screamed uncomfortably close past the Sphere. Fortunately these had no means of bursting, there being no explosives available on the planet.
The immediate effect of their successful attack upon the invaders was the latters’ withdrawal of their left encircling spur, and an evident preparation for a concentrated frontal attack.
Having looked to all important details of preparation to resist such an attack, Robert snatched a few hours of sleep. He lay down with his clothes on, exacting the promise that he would be wakened upon the first signs of an actual attack. Pickets were posted so that the enemy could not approach closer without their knowledge. The Sphere had been brought down again and Robert and his companions rested in their quarters within the palace.
It was not till close upon dawn that Robert was aroused by Taggert’s shaking him vigorously.
“Hate to do it, Bob,” he was saying, as Robert sat up suddenly, “but those Wops are getting ready to raise hell again. Old Kharnov has sent a note of defiance, stating that as he will shortly be in possession of Svergad the temporary shutting off of the water supply doesn’t matter.”
Robert was on his feet in a moment and was striding through the doorway when he became aware of a hesitant restraining hand upon his arm. He turned to see Zola at his side. She crept into his arms.
“Darling!”
“Ah, my Robert, they would not let me come to you because Zola’s love does not matter when everyone is so busy fighting. But I couldn’t let you go away again without seeing you.”
“Little ghost! You come and go like a dream. How did you get here at this time?”
“Taggert, he helped me. No one else knows but my maid.”
“Good old Tag! But now I must hurry, dear, to help fight for you.”
“Take me with you, Ro-bert.”
“Not now, sweetheart. Stay here in safety till I return, and then you shall go back home with me if you wish,”
“And be with you always, my Robert?”
“Always!”
Here Taggert appeared suddenly, as from nowhere.
“Sorry to interrupt your tête-à-tête, people, but we must be getting on.”
A hurried leave-taking followed. Zola placed in Robert’s hands a small package, which he did not have time to examine then.
A thick haze hung over the dark landscape, which was just visible in the dim starlight. A tense quiet prevailed.
The Sphere’s stall was readied quickly. All was well, and a few minutes later Robert and Taggert were rising rapidly in it above the sleeping city. The package given Robert by Zola was discovered to contain a small bottle of excellent wine and some lana, a nutritious cake, both of which were quite welcome, as he had not eaten anything for several hours.
Rising to a height of about four thousand feet, Robert allowed the Sphere to drift slowly over the enemy’s lines. With the ports open, the sound of activity below came to them with startling clearness. It was plain that preparations were being made for an attack on the city.
Robert had reduced the speed of the gyrostats to a minimum in order that the invaders might not be aware of its proximity. Every light in the Sphere was extinguished. It hung above the busy Martians—a great, dark globe of unsuspected menace.
Suddenly a sharp command rang out below. Immediately there followed a series of flashes accompanied by a corresponding series of dull thuds—sounds of the curious Martian electric artillery in action. Robert’s heart sank as he thought of Zola’s danger.
With the first thuds of the artillery below and the answering fire from the metropolis, the entire plain seemed fairly to seethe with activity. Bugles were blown, and commands rang out above the other sounds.
Robert switched on the Sphere’s giant searchlight. A blinding shaft of light shot down upon the broiling mass of humanity beneath. A great cry of consternation was wafted up to them.
“Not exactly elated at our presence,” remarked Taggert, dryly.
“We’ll be about as welcome as a plague a few minutes from now,” remarked Robert.
Swinging the reflector about, he followed every movement of the army of invaders, pausing at intervals to flash instructions to the defenders by a prearranged code of signals corresponding to the smoke signals of the day. Already the enemy was swarming upon the small force of defenders in the outskirts of the metropolis.
Several projectiles sang past the Sphere, indicating that the invaders were not going to submit to its presence idly. A number of smaller searchlights were directed upon it from beneath, almost blinding Robert and Taggert as their eyes sought to pierce the darkness below. The invaders were not without defense.
Adopting a swift, staggered course, Robert managed partly to avoid the blinding beams of light. Instructing Taggert to continue these tactics, Robert prepared to use the Sphere’s powerful weapon, the Norrensen Tube, against their enemies. He prayed only that it would not fail him now, and that their power would hold out long enough.
Calling out to Taggert to steady the Sphere’s course, Robert carefully aimed the tube into the thickest of the invaders where Taggert played the searchlight’s shaft back and forth. Robert pulled the lever releasing the lightning bolt!
A blinding flash, and a rending crash followed! The Sphere vibrated like a violin string. Only the goggles which they wore made it possible for Robert and Taggert to look upon the jagged pillar of incandescent flame which spattered upon the plain below with terrific force. So swift and brilliant was its course, that almost ere it had registered upon the retina of their eyes, it was gone, leaving them nearly powerless to see.
When they were again able to see and hear with fair distinctness, they became aware of a great hubbub below. The firing of the artillery had ceased and the attack of the invaders had turned into a rout. Hakon’s men were driving them back like sheep!
“God!” ejaculated Taggert, for once jarred out of his habitual sangfroid.
Robert was silent.
A vast pit was visible where the bolt had struck, and the bodies of hundreds of men were strewn round it. The demoralization of that division for the present was complete. The destructive force of the bolt was appalling, but the spectacle it presented had been even more so. The invaders were terrified beyond control by panic fear of this leaping bolt of fire from above.
Robert had no desire to take lives unnecessarily: If the first bolt was sufficient to cause the invaders to retreat or to cease fighting, he determined not to release a second one. He studied closely the movements of the armies. As if afraid to antagonize the Sphere further, the invaders had ceased to play the beams of their searchlights upon it.
In the east the first faint flush of dawn was visible. Already the tall spires of the metropolis were touched with coral.
Robert became aware that the Sphere had settled too close to the ground for safety in case of further firing from the hostile artillery.
“Better raise her another thousand, Taggert,” he called, turning to the latter, who was operating the machinery.
“Just what I was trying to do, old man, but she doesn’t respond.”
A swift examination proved Robert’s fears—that their reserve of power had been virtually exhausted by the tube! The speed of the gyrostats was perceptibly slackening. The Sphere was sinking!
Feverishly they turned to the engine which drove the dynamo. With this running, enough current soon would be generated to lift the Sphere out of danger. It was then that the extent of their calamity was discovered. The engine stubbornly refused to start, for one of those mysterious reasons to which engines are addicted. It persistently defied their combined efforts to diagnose the trouble.
In order to avoid crashing upon the plain, now less than a thousand feet below, Robert swung the disk upright and opened the shutters from its entire face. Even with its weakened power, unaided by the dying current, it would be almost sufficient to balance the Sphere’s weight, as long as the gyrostats were turning slowly. Thus the crash might be averted, but at the same time it was impossible to utilize any side pull of the disk to carry them beyond the enemy’s lines. They were facing capture—perhaps death!
Finding that each was in the other’s way, Taggert, who had a knowledge of engines, continued to tinker with it while Robert looked on from a window, where he kept an eye also on the plain below.
The Sphere continued to settle slowly, though they knew not what moment the gyrostats might stop, allowing them to crash down upon the plain. With each hundred feet of descent their hope grew stronger; but that they would fall into the enemy’s hands was now inevitable, for they were sinking into the very center of the camp.
Off to the south the sounds of fighting had ceased. Stretcher bearers were bringing in the wounded from that direction. Robert wondered dully how long it would be before he and Taggert would fall into the hands of the invaders.
Curiously enough, the Martians below were equally perturbed at the approach of the Sphere. Having witnessed its terrible destructive power, they felt absolutely at its mercy, and feared even to train a gun on it for fear that they would be wiped out immediately in retaliation. So far they did not suspect that the Sphere was not descending at the will of its occupants.
Realization of this occurred to Robert.
“Maybe we can bluff it through, Tag,” he said, hopefully. “It’s our only chance.”
By this time the Sphere had settled to within a bare fifty yards of the ground. Its buoyancy was now virtually the same as the slightly denser atmosphere at this height. It drifted slowly for several minutes, the gyrostats continuing to revolve softly.
The Martians had crowded round in a generous circle below. Mingled fear and curiosity were written upon their upturned faces, which could be seen quite clearly in the rapidly brightening daylight. A pompous officer pushed forward into the open space directly beneath the Sphere. Robert leaned out and addressed this individual.
“As emissaries of his excellency, the Governor of Svergad, I demand the immediate withdrawal of these forces,” Robert began, affecting a confidence which he was far from feeling.
“Fine. Go to it, boy!” encouraged Taggert in a hoarse whisper.
The officer did not seem surprized at Robert’s demand. But, unfortunately, in spite of his pompous manner, it appeared that he was not of sufficiently high rank to treat with so important a matter. Every moment was precious, for at any instant the Sphere might betray their weakness by settling to the ground.
The officer politely stated that their demand would be referred at once to the generalissimo. Realizing the importance of satisfactorily completing negotiations before the Sphere descended, Robert decided to take a bold stand.
“The generalissimo will not do. I must speak with the emperor quickly—here.”
As expected, the officer was visibly taken aback. Several valuable, fleeting seconds passed before he recovered from his surprize and indecision.
“Your request will be communicated to the emperor at once through the generalissimo,” he answered presently.
The minutes seemed like hours as Robert and Taggert anxiously awaited the reappearance of the official. Meanwhile the Sphere very slowly settled lower and lower. Taggert’s efforts to start the engine had availed nothing. They could but wait idly with what patience they could summon. To have attempted utilizing part of the disk’s power to carry them beyond the enemy’s lines would but have resulted in disaster, for their present buoyancy was maintained only with the aid of the disk’s power (directed absolutely perpendicularly).
A small group moving toward them heralding the probable approach of the emperor or generalissimo revived hope in their breasts. They might yet maintain their strategic position long enough to drive home a bargain that the Martians would honor when they were obliged to descend and attempt to bluff their way through a difficult situation somehow.
“The old boy himself,” ejaculated Taggert as the group drew near.
Robert recognized the emperor in a car pulling up below. Seated opposite him was the officer to whom they had first talked, while beside the emperor was a much decorated and bedecked individual who he hoped was the generalissimo himself.
The latter stepped out of the car after the officer, and assisted the emperor to alight. The three of them slowly paced beneath the Sphere as it drifted lightly with the soft morning breeze. The emperor was plainly angered and making a poor attempt to conceal the fact.
“What means this rude summons which his Highness, the emperor, has chosen to humor?” said the generalissimo; for that this was the generalissimo they quickly discovered. His voice carried up to them clearly. Barely thirty feet separated them now.
“I will speak directly with the emperor himself,” Robert began. “As emissary of his Highness, the Governor of Svergad, I demand the immediate withdrawal of all forces from this region. Unless such a movement is begun without delay, we are prepared to wipe out your entire army by means of the terrible weapon which you have seen.”
The emperor raised a countenance dark with passion. The generalissimo checked him with a nervous grip on his arm as he was about to speak, addressing him earnestly in an undertone.
The emperor calmed himself with evident effort.
“You have the advantage of us,” he said. “Therefore, my armies will retire at once; but I warn you that you shall be conquered in the end and be made to suffer for this.”
“Very well, your Highness. I suggest that you give orders immediately for their retirement as, unless it is commenced within a few minutes. I shall resume their destruction.”
Again the generalissimo was obliged to restrain the emperor’s burst of passion. A moment later, at a curt nod of assent, from the emperor, the generalissimo dispatched the officer with a command to begin an immediate general retirement of all forces.
The first contingent was soon moving northward. The emperor and generalissimo had departed ominously for their headquarters. The Sphere continued to drift idly, settling ever closer to the ground. The enemy forces still stretched more than a mile between the Sphere and the city. How Robert and Taggert yearned for a stiffening of the breeze that they might be swept safely beyond the enemy’s lines before the descending Sphere placed them in their power! Even now soldiers below paused in their preparations for retreat to gaze up at them curiously, albeit anxiously, evidently wondering why the Sphere hovered so low. Should the true reason be guessed, their temporary victory would be lost.
The next ten minutes seemed like an eternity to Robert. It had brought them only a little nearer the city and their friends, while scarcely thirty feet separated them from the enemy. Some of the troops were already marching off toward the south beneath them, but it was a physical impossibility for the thousands still between the Sphere and its goal to move out of the way in less than half an hour. And half an hour spelled almost certain disaster for the Sphere.
“Looks as if we’ll have to indulge in a little more diplomacy,” Robert remarked.
“Drop in upon his Royal Highness to bid him goo’bye, so to speak,” said Taggert.
“Something like that.”
At this moment the suspense was broken by a sudden lurch of the Sphere. The gyrostats had stopped!
With but the disk’s diminished power to break its fall, the Sphere dropped into the sand with a jarring thud.
The Martians had carefully avoided the section beneath the Sphere. Consequently it fell clear. For several minutes they kept their distance. It was evident that they all feared this mysterious machine greatly.
Presently a pompous officer strode into the space about the Sphere. Clearly he saw in the situation great possibilities for his own future and he intended making the most of it. Yet, like the rest, he was not certain that the Sphere was as helpless as it seemed. Before he had given an order. Robert stepped out of the Sphere.
Robert interrupted the officer as he was about to speak.
“I come to give warning that unless the retirement of all the emperor’s forces is accomplished more rapidly, I will resume their destruction,” he said, imperiously.
The Martian was visibly undecided. Perhaps he and his regiment would be wiped out if he attempted to hold the Sphere. He observed Taggert glaring at him balefully from a window. Nevertheless he was a brave man, especially when he thought of the brilliant future he might enjoy if he got away with this. A disagreeable smile disfigured his sharp-featured countenance.
“I think the emperor will soon have changed his mind about the retirement—just as soon as he knows that you have honored him by landing within his lines.”
“The emperor is too wise a man to delay the withdrawal of these troops,” answered Robert, “for even at this moment, should I choose, every man in sight would be blasted into atoms at a signal from me!”
The cocky officer’s assurance again was visibly shaken. Neither knowing that the death-dealing Norrensen shaft was rendered useless on account of its outlet being buried in the sand, nor being certain that the Sphere’s power was exhausted, he must have feared instant annihilation if he persisted. A cunning light came into his eyes suddenly, and was as quickly veiled. Affecting a friendly attitude he strode over to within a couple feet of Robert. To have backed away from him would but have advertised their weakness, and any retreat from the circle about them was impossible. So he stood his ground and waited the officer’s next move.
As if about to take Robert into his confidence, he placed his hand upon Robert’s shoulder. Then like a flash he rapped out a command, at the same instant covering Robert with his lahan, the Martian electric automatic.
Immediately the ring of Martians closed in upon the Sphere, while the officer’s two aids hurried to his help. Counting on his immunity from a possible blast from the Sphere while in close proximity to Robert, the crafty officer had dared to defy the Sphere. But he had not counted upon his prisoner’s hot-headedness.
Even as he whipped out the lahan, Robert started a dashing uppercut to his head. Before the surprized officer could fire or dodge, the blow caught him on the point of his jaw with a beautiful precision. He staggered and fell just before his anxious aids could reach him. Notwithstanding the gravity of the situation, Robert could not repress a laugh over the comical appearance of the little, pointed red beard on his late opponent’s chin, which was tilted serenely skyward, as he sprawled on his pompous back.
A few minutes later Robert was securely bound and led roughly away. His last glimpse of the Sphere showed him a ring of shouting Martians round it, but no sign of Taggert.
