Invaders from the Infinite by John W. Campbell (well read books .txt) 📕

Rushing was useless. He stood, and prepared to give battle. A molecular ray reached out⁠—and disappeared in flaring ions on a shield utterly impenetrable in the ionizing atmosphere.

Arcot meanwhile watched the instrument of his shield. The Thessian shield would have been impenetrable, but his shield, fed by less efficient tubes, was not, and he knew it. Already the terrific energy of the Thessian ray was noticeably heating the copper plates of the tube. The seal would break soon.

Another ray reached out, a ray of flaring light. Arcot, watching through the “eyes” of his telectroscope viewplates, saw it for but an instant, then the “eyes” were blasted, and the screen went blank.

“He won’t do anything with that but burn out eyes,” muttered the terrestrian. He pushed a small button when his instruments told him the rays were off. Another scanner came into action, and the viewplate was alive again.

Arcot shot out a cosmic ray himself, and swept the Thessian with it thoroughly. For the instant he needed the enemy ship was blinded. Immediately the Ancient Mariner dove, and the automatic ray-finders could no longer hold the rays on his ship. As soon as he was out of the deadly molecular ray he shut off his screen, and turned on all his molecular rays. The Thessian ship, their own ray on, had been unable to put up their screen, as Arcot was unable to use his ray with the enemy’s ray forcing him to cover with a shield.

Almost at once the relux covering of the Thessian ship shone with characteristic iridescence as it changed swiftly to lux metal. The molecular ray blinked out, and a ray screen flashed out instead. The Thessians were covering up. Their own rays were useless now. Though Arcot could not hope to destroy their ray shield, they could no longer attack his, for their rays were useless, and already they had lost so much of the protective relux, that they would not be so foolhardy as to risk a second attack of the ray.

Arcot continued to bathe the ship in energy, keeping their “eyes” closed. As long as he could hold his barrage on them, they would not damage him.

“Morey⁠—get into the power room, strap onto the board. Throw all the power-coil banks into the magnets. I may burn them out, but I have hopes⁠—” Arcot already had the generators going full power, charging the power coils.

Morey dived. Almost simultaneously the Thessians succeeded in the maneuver they had been attempting for some time. There were a dozen rays flaring wildly from the ship, searching blindly over the sky and ground, hoping to stumble on the enemy ship, while their own ship dived and twisted. Arcot was busily dodging the sweeping rays, but finally one hit his viewplates, and his own ship was blind. Instantly he threw the ray screen out, cutting off his own molecular ray. His own cosmics he set rotating in cones that covered the three dimensions⁠—save below, where the city lay. Immediately the Thessian had retreated to this one segment where Arcot did not dare throw his own rays. The Thessian cosmics continued to make his relux screens necessary, and his ship remained blind.

His ray screen was showing signs of weakening. The Thessians got a third ray into position for operation, and opened up. Almost at once the tubes heated terrifically. In an instant they would give way. Arcot threw his ship into space, and let the tubes cool under the water jacket. Morey reported the coils ready as soon as he came out of space.

Arcot cut in the new set of eyes, and put up his molecular ray screen again. Then he cut the energy back to the coils.

Half a mile below the enemy ship was vainly scurrying around an empty sky. Wade laughed at the strange resemblance to a puppy chasing its tail. The Ancient Mariner was utterly lost to them.

“Well, here goes the last trick,” said Arcot grimly. “If this doesn’t work, they’ll probably win, for their tubes are better than ours, and they can maneuver faster. By win I mean force us to let them attack Ortol. They can’t really attack us; artificial space is a perfect defense.”

Arcot’s molecular ray apprized the Thessians of his presence. Their screen flared up once more. Arcot was driving straight toward their ship as they turned. He snapped the relux screens in front of his eyes an instant before the enemy cosmics reached his ship. Immediately the thud of four heavy relays rang through the ship. The quarter of a million ton ship leaped forward under a terrific acceleration, and then, as the four relays cut out again, the acceleration was gone. The screen regained life as Arcot opened the shutters. Before them, still directly in their path, was the huge Thessian ship. But now its screen was down, the relux iridescent in decomposition. It was falling, helplessly falling to the rocky plateau seven miles below. Its rays reached out even yet⁠—and again the Ancient Mariner staggered under the terrific pull of some acceleration. The Thessian ship lurched upward, and a terrific concussion came, and the entire neighborhood of that projector disappeared in a flash of radiation.

Arcot drove the Ancient Mariner down beneath the Thessian ship in its long fall, and with a powerful molecular beam ripped a mighty chasm in the deserted plateau. The Thessian ship fell into a quarter mile rift in the solid rock, smashing its way through falling debris. A moment later it was buried beneath a quarter mile of broken rock as Arcot swept a molecular beam about with the grace of a mine foreman filling breaks.

An instant later, a heat ray followed the molecular in dazzling brilliance. A terrific gout of light appeared in the barren rocks. In ten minutes the plateau was a white hot cauldron of molten rocks, glowing now against a darkening sky. Night was falling.

“That ship,” said Arcot with
