Still upon them we sprang, there in the nebula's fires, our force-shafts and red rays whirling ceaselessly through the thundering flames about us toward them, though sullenly still their beams sprang to meet us. Through that inferno of flame, between and through the whirling ships about us, our own craft leapt, its cylinders still stabbing forth crumpling death to the oval ships about us, and then suddenly, in answer to some signal flashed among them, all those oval craft, those serpent-ships, had driven swiftly upward from the mighty battle, into the roaring fires above us. In those fires, while we too drove up through the flaming ocean in pursuit of them, they gathered for an instant, massing together, and then were flashing away, through the nebula's flaming sea and out of it into open space once more, flashing together back toward the galaxy's edge.
"The Cancer cluster," Jhul Din was screaming, now. "They're in flight-they're heading back toward the cluster."
But already I had pressed swiftly on the keys before me, and about us our ships were massing again, the galaxy-ships with us now; and then close-massed together we were racing outward, too, out of the mighty sea of flame about us, bursting out of the titanic nebula into the open spaces of the galaxy once more, its thronging suns all about us. Through those suns, back toward the galaxy's edge in swift flight, the five thousand remaining serpent-ships were flashing, the only surviving remnant of their vast fleet, that our two armadas had conquered and all but destroyed. Back toward the Cancer cluster they were fleeing, upon whose thronging worlds all the hordes of the serpent-races were massed, and within which those hordes, we knew, would be laboring still to complete the great cone that now we could destroy. So on after them our own fleet leapt, a score of thousands of mighty ships in close formation thundering after our flying enemy.
Past mighty, flaming suns we were racing, in pursuit, past slow-turning great worlds that moved about those suns and that we raced between and past, through the galaxy's giant stars toward its edge, toward the Cancer cluster. On-on-after the fleeing serpent-craft we raced, until far before us through the crowding suns there came into view the great cluster toward which they were heading, a gigantic, globular swarm of suns there at the galaxy's edge. The serpent-ships had reached it, now, were dropping swiftly down toward it, and as we too flashed above it we dropped after them in hot pursuit. Down-down-the great ball of flaming suns was growing swiftly in size as we neared it, the countless thronging worlds between those suns, packed now with the serpent-races, visible beneath-down-down-and then suddenly, in obedience to some unseen order, the serpent-ships fleeing downward beneath us had halted, had turned, and then were driving straight back up toward us.
So utterly unlocked for was that swift, fierce attack that before we could swerve aside our downward-rushing thousands of craft had crashed straight into the uprushing serpent-ships. Then the moment after that wild shock in which hundreds, thousands of ships had smashed head-on together, there was battle again there above that mighty ball of suns, with the giant splendor of our galaxy to one side and the infinite vault of outer space to the other, a battle such as in sheer, concentrated intensity none of us had ever yet experienced. Like senseless mechanisms, with the mad energy of despair, the serpent-ships drove toward us, flinging away their lives to hold us longer from the great cluster beneath and its crowded, serpent-peopled worlds, throwing themselves upon us with such awful fierceness that, outnumbering them as we did, our fleet reeled and staggered there beneath their blows.
Our ships were falling by the hundreds each moment, but now we gripped ourselves, sprang upon the attacking serpent-ships with a fury that matched their own, summoning all the strength of despair ourselves as the vast battle hung thus in the balance, ourselves leaping down upon the serpent-ships with a suicidal recklessness that sent them into annihilation swiftly beneath us. For a single wild moment, it seemed, their ships and ours alike had gathered their utmost powers for one last supreme effort, were throwing themselves upon each other with a last mad burst of strength, and in that moment death-beam and red ray and unseen force-shafts flashed thick through space from ship to ship. Then the serpent-ships were thinning in number before us, fewer and fewer, as regardless of our losses we pressed our fierce attack, until at last but a scant score of them remained, a score that in the next moment were gone also, flaring crimson or crumpling and collapsing. A battered remnant of what had once been two tremendous fleets, but ten thousand ships left of all our countless thousands we hung there in space above the cluster-alone. The serpent-ships were gone at last. The serpent-fleet was no more.
"We've won!" My cry of triumph was taken up and repeated, by Jhul Din beside me, by our followers beneath, by all, I knew, in our ships about us as we hung there. We had won. Had annihilated to the last one the countless serpent-ships, there in awful battle, reeling with them out of the outer void and through the galaxy, through thundering suns and whirling worlds, past dark-star and comet, through the mighty flames of the great nebula. Had swept the last of their fleet from space and now were moving down toward the great cluster beneath, toward the thronging suns and countless worlds among them, where all the hordes of the serpent-races were massed, dropping down to destroy the last mighty mechanism with which they had sought to conquer and annihilate us. We had-
But what was that below? Our downward-rushing ships had paused, millions of miles still above the great cluster, and we were gazing down toward it, toward a vast, dark shape that was rising from among its swarming suns! A colossal dark cone, that was coming slowly, deliberately, up among those suns and at sight of which our cries had died on our lips, our faces masks of blank horror! It was the mighty death-beam cone of the serpent-creatures! It was the colossal generator of death that they had brought with them unfinished from the dying universe, that their serpent-hordes in the cluster beneath had labored upon while we had fought our mighty battle, and that now, while the last of the serpent-ships had held us back a moment longer, they had completed. Up toward us it was coming, slowly rising among the mighty cluster's suns, ponderously, deliberately, and we knew that in a moment more it would be rising out of that cluster, would be annihilating all life in our ships with a single sweep of its colossal beams of death, would be sailing deliberately on to wipe all the life from the galaxy's worlds, and give those worlds forever to the serpent-hordes massed in the cluster beneath! We had not won, but lost.
There was a silence-a silence of death-in that moment, as the stupendous cone rose up through the ball of suns beneath. Still, silent, we hung there-our doom rising up beneath us-a moment in which there whirled through my brain confused, swift visions-our awful battle in vain-our universe and the Andromeda universe the serpent-peoples', our races gone forever-and then suddenly into my whirling brain there penetrated a choking cry. It was from Jhul Din, and he was at the window, strangling, staggering, pointing out into the black void of outer space beside us, out to where a little swarm of great shapes were rushing headlong toward us out of that void. A hundred great shapes that were like mighty hemispheres of metal, domed and flat-bottomed and gleaming-
"It's the sun-swinging ships!" Jhul Din's great cry stabbed into my dazed brain like a sword of sound. "It's Korus Kan and the sun-swinging ships. They escaped from the attraction-ships that captured them-have come across the void after us-"
