And they did. Weightless and without inertia, gravitation powerless against her neutralizing generators, the great super-ship came from her practically infinite velocity to an almost instantaneous halt in the outermost, most tenuous layer of the earth's atmosphere. Her halt was but momentary. Inertia restored and gravitation allowed again to affect her mass, she dropped at a sharp angle downward. More than dropped; she was forced downward by one full battery of projectors; projectors driven by iron-powered generators. Soon they were over the Hill, whose violet screens went down at a word.
Flaming a dazzling white from the friction of the atmosphere through which she had torn her way, the Boise slowed abruptly as she neared the ground, plunging toward the surface of the small but deep artificial lake below the Hill's steel apron. Into the cold waters the space-ship dove, and even before they could close over her, furious geysers of steam and boiling water erupted as the stubborn alloy gave up its heat to the cooling liquid. Endlessly the three necessary minutes dragged their slow way into time, but finally the water ceased boiling and Rodebush tore the ship from the lake and hurled her into the gaping doorway of her dock. The massive doors of the air-locks opened, and while the full crew of picked men hurried aboard with their personal equipment, Samms talked earnestly to the two scientists in the control room.
" ... and about half the fleet is still in the air. They aren't attacking; they are just trying to keep her from doing much more damage until you can get there. How about your take-off? We can't launch you again—the tracks are gone—but you handled her easily enough coming in?"
"That was all my fault," Rodebush admitted. "I should have neutralized inertia first, but I had no idea that the fields would extend beyond the hull, nor that they wouldn't act simultaneously. We'll take her out on the projectors this time, though, the same as we brought her in—she handles like a bicycle. The projector blast tears things up a little, but nothing serious. Have you got that Pittsburgh beam for me yet? We're about ready to go."
"Here it is, Doctor Rodebush," came the secretary's voice, and upon the screen there flashed into being the view of the events transpiring above that doomed city. "The dock is empty and sealed against your blast," and thereupon "Good-bye, and power to your tubes!" came Samms' ringing voice.
As the words were being spoken, mighty blasts of power raved from the driving projectors and the immense mass of the super-ship shot out through the portals and upward into the stratosphere. Through the tenuous atmosphere the huge ship rushed with ever-mounting speed, and while the hope of Triplanetary drove eastward Rodebush studied the ever-changing scene of battle upon his plate and issued detailed instructions to the highly trained specialists manning every offensive and defensive weapon.
But the Nevians did not wait to join battle until the newcomers arrived. Their detectors were sensitive—operative over untold thousands of miles—and the ultra-screen of the Hill had already been noted by the invaders as the earth's only possible source of trouble. Thus the departure of the Boise had not gone unnoticed, and the fact, that, not even with his most penetrant rays could he see into her interior, had already given the Nevian commander some slight concern. Therefore, as soon as it was determined that the great ship was being directed toward Pittsburgh the fish-shaped cruiser of the void went into action.
High in the stratosphere, speeding eastward, the immense mass of the Boise slowed abruptly, although no projector had slackened its effort. Cleveland, eyes upon interferometer grating and spectrophotometer charts, fingers flying over calculator keys, grinned as he turned toward Rodebush.
"Just as you thought, Skipper; an ultra-band pusher. C4V63L29. Shall I give him a little pull?"
"Not yet; let's feel him out a little before we force a close-up. We've got plenty of mass. See what he does when I put full push on the projectors."
As the full power of the Terrestrial vessel was applied the Nevian was forced backward, away from the threatened city, against the full drive of her every projector. Soon, however, the advance was again checked, and both scientists read the reason upon their plates. The enemy had put down re-enforcing rods of tremendous power. Three compression members spread out fanwise behind her, bracing her against the low mountainside, while one huge tractor beam was thrust directly downward, holding in an unbreakable grip a cylinder of earth extending deep down into bedrock.
"Two can play at that game!" And Rodebush drove down similar beams, and forward-reaching tractors as well. "Strap yourselves in solid, everybody!" he sounded a general warning. "Something is going to give way somewhere soon, and when it does we'll get a jolt!"
And the promised jolt did indeed come soon. Prodigiously massive and powerful as the Nevian was, the Boise was even more massive and more powerful; and as the already enormous energy feeding the tractors, pushers, and projectors was raised to its inconceivable maximum, the vessel of the enemy was hurled upward, backward; and that of earth shot ahead with a bounding leap that threatened to strain even her mighty members. The Nevian anchor-rods had not broken; they had simply pulled up the vast cylinders of solid rock that had formed their anchorages.
"Grab him now!" Rodebush yelled, and even while an avalanche of falling rock was burying the countryside, Cleveland snapped a tractor ray upon the flying fish and pulled tentatively.
Nor did the Nevian now seem averse to coming to grips. The two warring super-dreadnaughts darted toward each other, and from the invader there flooded out the dread crimson opacity which had theretofore meant the doom of all things Solarian. It flooded out and engulfed the immense mass of humanity's hope in its spreading cloud of redly impenetrable murk. But not for long. Triplanetary's super-ship boasted no ordinary Terrestrial defense, but was sheathed in screen after screen of ultra-vibrations: imponderable walls, it is true, but barriers impenetrable to any unfriendly wave. To the outer screen the red veil of the Nevians clung tenaciously, licking greedily at every square inch of the shielding sphere of force, but unable to find an opening through which to feed upon the steel of the Boise's armor.
"Get back—'way back! Go back and help Pittsburgh!" Rodebush drove an ultra-communicator beam through the murk to the instruments of the Terrestrial admiral; for the surviving warships of the Fleet—its most powerful units—were hurling themselves forward, to plunge into that red destruction. "None of you will last a second in this red field. And watch out for a violet field pretty soon—it'll be worse than this. We can handle them alone, I think; but if we can't, there's nothing in the System that can help us!"
And now the hitherto passive screen of the super-ship became active. At first invisible, it began to glow in livid, violet light, and as the glow brightened to unbearable intensity the entire spherical shield began to increase in size. Driven outward from the super-ship as a center, its advancing surface of seething energy consumed the crimson murk as a billow of blast-furnace heat consumes a cloud of snowflakes in the air above its shaft. Nor was the red death-mist all that was consumed. Between that ravening surface and the armor skin of the Boise there was nothing. No debris, no atmosphere, no vapor, no single atom of material substance—the first time in Terrestrial experience that an absolute vacuum had ever been attained!
Stubbornly contesting every foot of way lost, the Nevian fog retreated before the violet sphere of nothingness. Back and back it fell, disappearing altogether from all space as the violet tide engulfed the enemy vessel; but the flying fish did not disappear. Her triple screens flashed into furiously incandescent splendor and she entered, unscathed, that vacuous sphere, which collapsed instantly into an enormously elongated ellipsoid, at each focus a madly warring ship of space.
Then in that tube of vacuum was waged a spectacular duel of ultra-weapons—weapons impotent in air, but deadly in empty space. Beams, rays, and rods of Titanic power smote cracklingly against ultra-screens equally capable. Time after time each contestant ran the gamut of the spectrum with his every available ultra-force, only to find all channels closed. For minutes the terrible struggle wen
t on, then:
"Cooper, Adlington, Spencer, Dutton!" Rodebush called into his transmitter. "Ready? Can't touch him on the ultra, so I'm going onto the macro-bands. Give him everything you have as soon as I collapse the violet. Go!"
At the word the violet barrier went down, and with a crash as of a disrupting Universe the atmosphere rushed into the void. And through the hurricane there shot out the deadliest material weapons of Triplanetary. Torpedoes—non-ferrous, ultra-screened, beam-dirigible torpedoes charged with the most effective forms of material destruction known to man. Cooper hurled his canisters of penetrating gas, Adlington his atomic iron explosive bombs, Spencer his indestructible armor-piercing projectiles, and Dutton his shatterable flasks of the quintessence of corrosion—a sticky, tacky liquid of such dire potency that only one rare Solarian element could contain it. Ten, twenty, fifty, a hundred were thrown as fast as automatic machinery could launch them; and the Nevians found themselves adversaries not to be despised. Size for size, their screens were quite as capable as those of the Boise. The Nevians' destructive rays glanced harmlessly from their shields, and the Nevians' elaborate screens, neutralized at impact by those of the torpedoes, were impotent to impede their progress. Each projectile must needs be caught and crushed individually by beams of the most prodigious power; and while one was being annihilated dozens more were rushing to the attack. Then, while the twisting, dodging invader was busiest with the tiny but relentless destroyers, Rodebush launched his heaviest weapon.
The macro-beams! Prodigious streamers of bluish-green flame which tore savagely through course after course of Nevian screen! Malevolent fangs, driven with such power and velocity that they were biting into the very walls of the enemy vessel before the amphibians knew their defensive shells of force had been punctured! And the emergency screens of the invaders were equally futile. Course after course was sent out, only to flare viciously through the spectrum and to go black!
Outfought at every turn, the now frantically dodging Nevian leaped away in headlong flight, only to be brought to a staggering, crashing halt as Cleveland nailed her with a tractor beam. But the Terrestrials were to learn that the Nevians held in reserve a means of retreat. The tractor snapped—sheared off squarely by a sizzling plane of force—and the fish-shaped cruiser faded from Cleveland's sight, just as the Boise had disappeared from the communicator plates of Radio Center, back in the Hill, when she was launched. But though the plates in the control room could not hold the Nevian, she did not vanish beyond the ken of Randolph, now Communications Officer in the super-ship. For, warned and humiliated by his losing one speeding vessel from his plates in Radio Center, he was now ready for any emergency. Therefore as the Nevian fled, Randolph's spy-ray held her, automatically behind it as there was the full output of twelve special banks of iron-driven power tubes; and thus it was that the vengeful Terrestrials flashed immediately along the Nevians' line of flight. Inertialess now, pausing briefly from time to time to enable the crew to accustom themselves to the new sensations, the Boise pursued the invader; hurtling through the void with a velocity unthinkable.
"He was easier to take than I thought he would be," Cleveland grunted, staring into the plate.
"I thought he had more stuff, too," Rodebush assented; "but I guess Costigan got almost everything they had. If so, with all our own stuff and most of theirs besides, we should be able to take them. They must have neutralization, too, to take off like that; and if it's one hundred per cent we'll never catch them ... but it isn't—there they are!"
"And this time I'm going to hold her or burn out all our generators trying," Cleveland declared, grimly. "Are you fellows down there able to handle yourselves yet? Fine! Start throwing out your cans!"
Space-hardened veterans all, the other Terrestrial officers had fought off the horrible nausea of inertialessness, just as Rodebush and Cleveland had done. Again the ravening green macro-beams tore at the flying cruiser, again the mighty frames of the two space-ships shuddered sickeningly as Cleveland clamped on his tractor rod, again the highly dirigible torpedoes dashed out with their freights of death and destruction. And again the Nevian shear-plane of force slashed at the Terrestrial's tractor beam; but this time the mighty puller did not give way. Sparkling and spitting high-tension sparks, the plane bit deeply into the stubborn rod of energy. Brighter, thicker, and longer grew the discharges as the gnawing plane drew more and more power; but in direct ratio to that power the rod grew larger, denser, and ever harder to cut. More and more vivid became the pyrotechnic display of electric brilliance, until suddenly the entire tractor rod disappeared. At the same instant a blast of intolerable flame erupted from the Boise's flank and the whole enormous fabric of her shook and quivered under the force of a terrific detonation.
"Randolph! I don't see them! Are they attacking or running?" Rodebush demanded. He was the first to realize what had happened.
"Running—fast!"
"Just as well, perhaps, but get their line. Adlington!"
"Here!"
"Good! Was afraid you were gone—that was one of your bombs, wasn't it?"
"Yes. Well launched, just inside the screens. Don't see how it could have detonated unless something hot and hard struck it in the tube; it would need about that much time to explode. Good thing it didn't go off any sooner, or none of us would have been here. As it is, Area Six is pretty well done in, but the bulkheads held the damage to Six. What happened?"
"We don't know, exactly. Both generators on the tractor beam went out. At first, I thought that was all, but my neutralizers are dead and I don't know what else. When the G-4's went out the fusion must have shorted the neutralizers. They would make a mess; it must have burned a hole down into number six tube. Cleveland and I will come down, and we'll all look around."
Donning space-suits, the scientists let themselves into the damaged compartment through the emergency air-locks, and what a sight they saw! Both outer and inner walls of alloy armor had been blown away by the awful force of the explosion. Jagged plates hung awry; bent, twisted, and broken. The great torpedo tube, with all its intricate automatic machinery, had been driven violently backward and lay piled in hideous confusion against the backing bulkheads. Practically nothing remained whole in the entire compartment.
"Nothing much we can do here," Rodebush said finally, through his transmitter, "Let's go see what number four generator room looks like."
That room, although not affected by the explosion from without, had been quite as effectively wrecked from within. It was still stiflingly hot; its air was still reeking with the stench of burning lubricant, insulation, and metal; its floor was half covered by a semi-molten mass of what had once been vital machinery. For with the burning out of the generator bars the energy of the disintegrating allotropic iron had had no outlet, and had built up until it had broken through its insulation and in an irresistible flood of power had torn through all obstacles in its path of neutralization.
"Hm-m-m. Should have had an automatic shut-off—one detail we overlooked," Rodebush mused. "The electricians can rebuild this stuff here, though—that hole in the hull is something else again."
"I'll say it's something else," the grizzled Chief Engineer agreed. "She's lost all her spherical strength—anchoring a tractor with this ship now would turn her inside out. Back to the nearest Triplanetary shop for us, I would say."
"Come again, Chief!" Cleveland advised the engineer. "None of us would live long enough to get there. We can't travel inertialess until the repairs are made, so if they can't be made without very much traveling, it's just too bad."
"I don't see how we could support our jacks...." The engineer paused, then went on. "If you can't give me Mars or Tellus, how about some other planet? I don't care about atmosphere, or about anything but mass. I can stiffen her up in three or four days if I can sit down on something heavy enough to hold our jacks and presses; but if we have to rig up space-cradles around the ship herself it'll take a long time—months, probably. Haven't got a spare pla
net on hand, have you?"
"We might have, at that," Rodebush made surprising answer. "A couple of seconds before we engaged we were heading toward a sun with at least two planets. I was just getting ready to dodge them when we cut the neutralizers, so they should be fairly close somewhere—yes, there's the sun, right over there. Rather pale and small; but it's close, comparatively speaking. We'll go back up into the control room and find out about the planets."
The strange sun was found to have three large and easily located children, and observation showed that the crippled space-ship could reach the nearest of these in about five days. Power was therefore fed to the driving projectors, and each scientist, electrician, and mechanic bent to the task of repairing the ruined generators; rebuilding them to handle any load which the converters could possibly put upon them. For two days the Boise drove on; then her acceleration was reversed, and finally a landing was effected upon the forbidding, rocky soil of the strange world.
It was larger than the earth, and of a somewhat stronger gravitation. Although its climate was bitterly cold, even in its short daytime, it supported a luxuriant but outlandish vegetation. Its atmosphere, while rich enough in oxygen and not really poisonous, was so rank with indescribably fetid vapors as to be scarcely breathable.
But these things bothered the engineers not at all. Paying no attention to temperature or to scenery and without waiting for chemical analysis of the air, the space-suited mechanics leaped to their tasks; and in only a little more time than had been mentioned by the chief engineer the hull and giant frame of the super-ship were as staunch as of yore.
"All right, Skipper!" came finally the welcome word. "You might try her out with a fast hop around this world before you shove off in earnest."
Under the fierce blast of her projectors the vessel leaped ahead, and time after time, as Rodebush hurled her mass upon tractor beam or pressor, the engineers sought in vain for any sign of weakness. The strange planet half girdled and the severest tests passed flawlessly, Rodebush reached for his neutralizer switches. Reached and paused, dumfounded, for a brilliant purple light had sprung into being upon his panel and a bell rang out insistently.
