Invasion Part 3

A second dark cloud swept forward in the gathering dusk and merged into the ma.s.s of fliers about the dome. Five minutes later, a third.

Dense as the air-traffic was, riding-lights were necessary. They began to appear in the deepening twilight. It seemed as if all the sky were alight with fireflies, whirling and swirling and fluttering here and there. But then the fire-drill began to emit a tiny wisp of smoke.

Thorn worked furiously. Then a tiny flickering flame appeared, which he nursed with a desperate solicitude. Then a larger flame. Then a roaring blaze! It could not be missed! A fire within the dome could not fail to be noted and examined instantly!

A searchlight beam fell upon them, illuminating him in a pitiless glare. Thorn waved his arms frantically. He had nothing with which to signal save his body. He flung his arms wide, and up, and wide again, in an improvised adaption of the telegraphic alphabet to gesticulation. He sent the watch call over and over again....

A little cloud of riding-lights swept toward the dome from an infinite distance away. Darkness was falling so swiftly that they were still merely specks of light as they swept up to and seemed to melt into the swirling, swooping ma.s.s of fliers about the dome....

Cold sweat was standing out on Thorn's face, despite the violence of his exertions. He was even praying a little.... And suddenly the searchlight beam flickered a welcome answer:

"W-e u-n-d-e-r-s-t-a-n-d. R-e-p-o-r-t."

Thorn flung his arms about madly, sending:

"G-e-t a-w-a-y q-u-i-c-k. C-o-m P-u-b-s h-e-r-e. W-i-l-l m-a-k-e o-t-h-e-r d-o-m-e o-u-t-s-i-d-e t-o t-r-a-p y-o-u."

The searchlight beam upon him flickered an acknowledgment. He knew what was happening after that. The G.C. phones would flash the warning to every ship, and every ship would dash madly for safety.... A sudden, concerted quiver seemed to go over the whirling maze of lights aloft. A swift, simultaneous movement of every ship in flight. Thorn breathed an agonized prayer....

There was a flash of blue light. For one fractional part of a second the stars and skies were blotted out. There was a dome of flame above him and all about the world, of bright blue flame which instantly was--and instantly was not!

Then there was a ghastly blast of green. Hexynitrate going off. In this glare were silhouetted a myriad motes in flight. But there was no noise. A second flare.... And then Thorn Hard, groaning, saw flash after flash after flash of green. Monster explosions. Colossal explosions. Terrific detonations which were utterly soundless, as the ships of the Fighting Force, in flight from the menace of which Thorn had warned them, crashed into an invisible barrier and exploded without cracking it.

It was August 24th, 2037. For three days, now, seven of the eight great combat-squadrons of the United Nations Fighting Forces had been prisoners inside a monstrous transparent dome of force. There was a financial panic of unprecedented proportions in the great financial districts of New York and London and Paris. Martial law was in force in Chicago, in Prague, in Madrid, and in Buenos Aires. The Com-Pubs were preparing an ultimatum to be delivered to the government of the United Nations. Thorn and Sylva were hunted fugitives within the inner dome of force, which protected the red rocket-ship from the seven combat squadrons it had imprisoned. Newspaper vendor-units were shrieking, "Air Fleet Still Trapped!" and a prominent American politician was promising his const.i.tuents that if a foreign nation dared invade the sacred territories of the United Nations, a million embattled private planes would take the air. And he seemed not even trying to be humorous! Scientists were wringing their hands in utter helplessness before the incredible resistance of the dome. It had been determined that the dome was a force-field which caused particles charged with positive electricity to attempt to move in a right-hand direction about the source of the field, and particles charged with negative electricity to attempt to move in a left-hand direction. The result was that any effort to thrust an external object into the field of force was an attempt to tear the negatively charged electrons of every atom of that substance, free from the positively charged protons of nuclei. An object could only be pa.s.sed through the field of force if it ceased to exist as matter--which was not an especially helpful discovery. And--Thorn Hard and Sylva were still hunted fugitives inside the inner dome.

The sun was an hour high when the helicopter appeared to hunt for them by day. After the first time they had never dared light a fire, because Kreynborg in the helicopter searched the hills for a glow of light. But this day he came searching for them by day. Thorn had speared a fish for Sylva with a stick he had sharpened by rubbing it on a crumbling rock. He was working discouragedly on a little contrivance made out of a forked stick and the elastic from his parachute-pack. He was haggard and worn and desperate. Sylva was beginning to look like a hunted wild thing.

Two hundred yards from them the most formidable fighting force the world had ever seen littered the earth with gossamer-seeming cellate wings and streamlined bodies at all angles to each other. And it was completely useless. The least of the weapons of the air-fleet would have been a G.o.dsend to Thorn and Sylva. To have had one ship, even the smallest, where they were would have been a G.o.dsend to the fleet. But two hundred yards, with the dome of force between, made the fleet just exactly as much protection for Sylva as if it had been a million miles away.

The droning hum of the helicopter came across the broken ground. Now louder, now momentarily muted, its moments of loudness grew steadily more strong. It was coming nearer. Thorn gripped his spear in an instinctive, utterly futile gesture of defense. Sylva touched his hand.

"We'd better hide."

They hid. Thick brush concealed them utterly. The helicopter went slowly overhead, and they saw Kreynborg gazing down at the earth below him. Nearly overhead he paused. And suddenly Thorn groaned under his breath.

"It's the flagship!" he whispered hoa.r.s.ely to Sylva. "Oh, what fools we were! The flagship! He knows the General would have brought it to earth opposite us, to question us!"

The flagship was nearly opposite. To find the flagship was more or less to find where Thorn and Sylva hid. But they had not realized it until now.

The speaker in the helicopter boomed above their heads.

"Ah, my friends! I think you hear me. Answer me. I haff an offer to make."

Shivering, Sylva pressed close to Thorn.

"Der Com-Pub fleet is on der way," said Kreynborg, chuckling.

"Sefen-eights of der United Nations fleet is just outside. You haff observed it. In six hours der Com-Pub fleet begins der conquest of der country and der execution of persons most antagonistic to our regime.

But I haff still weary weeks of keeping der air fleet prisoner, until its personnel iss too weak from starfation to offer resistance to our soldiers. So I make der offer. Come and while away der weary hours for me, and I except you both from der executions I shall findt it necessary to decree. Refuse, and I get you anyhow, and you will regret your refusal fery much."

Thorn's teeth ground together. Sylva pressed close to him.

"Don't let him get me, Thorn," she panted hysterically. "Don't let him get me...."

The droning, monotonous hum of the helicopter over their heads continued. The little flying-machine was motionless. The air was still. There was no other sound in the world.

Silence, save for the droning hum of the helicopter. Then something dropped. It went off with an inadequate sort of an explosion and a cloud of misty white vapor reared upward on a hillside and began to settle slowly, spreading out.... The helicopter moved and other things dropped, making a pattern....

"The air's still," said Thorn quite grimly. "That stuff seems to be heavier than air. It's flowing downhill, toward the dome-wall. It will be here in five minutes. We've got to move."

Sylva seemed to be stricken with terror. He helped her to her feet.

They began to move toward higher ground. They moved with infinite caution. In the utter silence of this inner dome, even the rustling of a leaf might betray them.

It was the presence of the air fleet within clear view that made the thing so horrible. The defenders of a nation were watching the enemy of a nation, and they were helpless to offer battle. The helicopter hummed and droned, and Kreynborg grinned and searched the earth below him for a sign of the man and girl who had been the only danger to his plan and now were unarmed fugitives. And there were four air-dreadnaughts in plain sight and five thousand men watching, and Kreynborg hunted, for sport, a comrade of the five thousand men and a woman every one of them would have risked or sacrificed his life to protect.

He seemed certain that they were below him. Presently he dropped another gas-bomb, and another. And then Sylva stumbled and caught at something, and there was a crashing sound as a sapling wavered in her grasp.... And Thorn picked her up and fled madly. But billowing white vapor spouted upward before him. He dodged it, and the helicopter was just overhead and more smoke spouted, and more, and more.... They were hemmed in, and Sylva clung close to Thorn and sobbed....

Five thousand men, in a thousand grounded aircraft, shouted curses that made no sound. They waved weapons that were utterly futile. They were as impotent as so many ghosts. Their voices made not even the half-heard whisper one may attribute to a phantom.

The fog-vapor closed over Thorn and Sylva as Kreynborg grinned mockingly at the raging men without the dome of force. He swept the helicopter to a position above the last view of Thorn and Sylva, and the downward-beating screws swept away the foggy gas. Thorn and Sylva lay motionless, though Thorn had instinctively placed himself in a position of defense above her.

The Fighting Force of the United Nations watched, raging, while Kreynborg descended deliberately into the area the helicopter-screws kept clear. While he searched Thorn's pockets reflectively and found nothing more deadly than small pebbles which might strike sparks, and a small forked stick. While he grinned mockingly at the raging armed men and made triumphant gesticulations before carrying Sylva's limp figure to the helicopter. While the little ship rose and swept away toward the rocket-plane.

It descended and was lost to view. Thorn lay motionless on the earth.

Seven-eighths of the fighting force of the United Nations was imprisoned within the s.p.a.ce between two domes of force no matter could penetrate. A ring two miles across and ten miles in outer diameter held the whole fleet of the United Nations paralyzed.

There was sheer panic through the Americas and Europe and the few outlying possessions of the United Nations.... And it was at this time, with a great fleet already half-way across the Pacific, that the Com-Pubs declared war in a fine gesture of ironic politeness. It was within half an hour of this time that the Seventh Combat Squadron--the only one left unimprisoned--dived down from fifty thousand feet into the middle of the Com-Pub fleet and went out of existence in twenty minutes of such carnage as is still stuff for epics.

The Seventh Squadron died, but with it died not less than three times as many of the foe. And then the Com-Pub fleet came on. Most of the original force remained; surely enough to devastate an undefended nation, to shatter its cities and butcher its people; to slaughter its men and enslave its women and leave a shambles and smoking ash-heaps where the very backbone of resistance to the red flag had been.

It was twenty minutes before Thorn Hard stirred. His lungs seemed on fire. His limbs seemed lead. His head reeled and rocked. He staggered to his feet and stood there swaying dully. A vivid light, brighter than the sunshine, played upon him from the flagship of the fleet which now was helpless to defend its nation. Thorn's befogged brain stirred dazedly as the message came.

"Com-Pub fleet on way. Seventh Combat-Squadron wiped out. Nation defenseless. You are only hope. For G.o.d's sake try something.

Anything."

Thorn roused himself by a terrific effort. He managed to ask a question by exhausted gestures in the Watch visual alphabet.

"Kreynborg took her to rocket-ship," came the answer. "She recovered consciousness before being carried inside."
