"Battle formation!"
Even as the deadly crimson bolts had shot up from the cubes toward us I had yelled the order into the instrument before me, and it was all that saved us from disaster in that moment, since in the split-second before the glowing bolts could reach us our cruisers had shifted their formation suddenly, only a score of them being struck by those glowing shafts. In that moment our cruisers had shifted into three long parallel lines, and then, as the massed cubes beneath flashed ever upward toward us, their glowing bolts blasting our cruisers, I had shouted another order into the speech-instrument above the great din beneath.
"The force-beams!" I cried. "Turn them on these cube-ships-push them down into the coma!"
There came a deep shout from Gor Han at the order, and from Jurt Tul's ship there issued through my instrument the amphibian's cool laugh. The next instant there were shooting downward from all our cruisers the great force-beams, broad beams, not of light but of darkness, of utter blackness and absence of light, of great force that was invisible itself but whose terrific power drove even the light-vibrations from its path and so made the force-beams seem beams of utter blackness. Down toward the uprushing cube-ships the black force-beams stabbed, and as they smote among those cubes those that were struck by them were driven suddenly downward with inconceivable power. Down, down, struggling vainly against the irresistible force-beams that pushed them, down, down until in a moment more those struck had been driven into the crimson sphere of the mighty coma beneath, vanishing in its immense lurid sea and there meeting annihilation instantly in spurts of leaping light!
Thus a full score of the hundred cube-ships below had been forced down to death in the comet in a single moment, but the rest were still leaping toward us and before we could loose more of the deadly force-beams they were just beneath us, among us, their crimson bolts blasting lightning-like about them, leaping from cube to cruiser. High above the titanic thundering comet, like flies above a sun, cubes and cruisers whirled and struck and ran, with crimson bolts and black force-beams stabbing thick through the void about us. I heard the shouts of Gor Han and Jurt Tul and Najus Nar from the instrument before me, screamed my orders into its opening as my own cruiser soared through the wild melee with black beams whirling. I glimpsed one of the cubes rocketing toward us, looming in an instant to immense size, a colossal metal cube thousands of feet square, through the transparent sections of which I could glimpse for a split-second the white-lit interior, a mass of intricate mechanisms among which clung the beings who manned it, black, shapeless masses that I but half glimpsed in that mad moment. Then from the cube's great side a glowing red bolt shot toward us, but a moment too late, since by then our cruiser had shot upward and our black forcebeam had smote down upon the cubeship to drive it into the glowing sea of death below!
About us, too, all our cruisers were speeding upward, in answer to my orders, and before the cubes could check our maneuver we were over them, all our dark force-beams smiting from above. Struck by those beams, all but a scant half-dozen of the remaining cubes drove down to doom in the coma's fiery sea, before they could rise to our level to resume the battle. The half-dozen left seemed to hover motionless a moment, then turned and sped away from us, back over the coma's crimson-glowing sphere toward the great tail of the comet, streaming out behind!
"We've beaten them!" Gor Han was bellowing. "They're trying to get away-"
"After them!" I yelled into the speech-instrument. "They're trying to get back inside the coma-they must have some way of getting inside!"
But my order had been unnecessary, for even as the half-dozen great cubes flashed away, our cruisers, still some eight hundred in number, had turned and were racing after them like unleashed hounds after their prey. Downward and backward we raced after them, low across the glowing surface of the great comet, over the deadly coma to where the faint, vast tail issued from it. Ahead we could see the six cubes fleeing onward, at a speed equal to our own, and the sight of them caused us to open to the last notch the power of our throbbing generators for that wild pursuit. Within moments, at that tremendous speed, there came into view ahead the rear rim of the coma's colossal glowing sphere, with the fainter glow that marked the currents of the great tail streaming back from the rim into the void of space.
