There was a terrific, rending shock as our great prow tore into the transparent-walled nose of the enemy ship, and beneath that shock we saw the whole fore portion of the oval ship crumpling up and collapsing, reeling away a shattered wreck of metal. Our own cruiser rocked and swayed crazily at the collision, and for a moment it seemed that we too were doomed, but the next our battered ship leapt forward, and in an instant was free of the masses of oval ships that had encircled us, and was driving now in toward the galaxy's suns, with a score of the oval ships behind in hot pursuit.

In we drove, speeding now past the great Cancer cluster as we flashed at our utmost speed into the galaxy, its great ball of gathered suns flaring in the black heavens to our left as we sped inward. Behind came our pursuers, racing on close after us; and now, glancing back beyond them, I saw the whole mighty fleet of the invaders, still fully three thousand ships in number, moving in toward the galaxy also, toward the great Cancer cluster, with its swarming suns and thronging worlds, saw the great fleet slowing, slanting down toward those suns, those worlds, and knew then that these invaders, having annihilated the galaxy's fleet, were settling upon the suns and worlds of the Cancer cluster as a first foothold in our universe, a base from which they could subdue all that universe. Then their fleet had vanished from our distance-windows as we fled on, and of the score of our pursuers all but three had turned back to rejoin that fleet.

The three remaining ships, though, drove straight on our track, and swiftly were overhauling us, though inside the galaxy they dared not use all their tremendous speed. Yet remorselessly after us they came, and I knew that moments more would see our end unless we could escape them. Directly ahead of us, though, there flamed a small crimson sun, a dying, planetless star not far inward from the Cancer cluster, largening each moment before us as we drove on toward it with terrific speed. As I saw it a last plan flashed through my brain, and I turned to Korus Kan.

"Head straight toward that sun!" I told him. "It's our only chance—to get in close and lose them in its corona!"

He nodded grimly, swerving the ship a little, and now straight toward the red star we raced, Jhul Din and I gazing out with him toward it as we flashed on, and then behind to where the gleaming three ships of the invaders drove after us. Swiftly they were overtaking us, two close behind us and the remaining one a little behind the two, but ahead the crimson star was filling almost all the heavens, now, a great sea of fiery red flame that stretched above and beneath us, ahead, as though occupying all the firmament. Its glare was awful, now, for we were racing straight in toward the mighty corona of it, the glowing outer atmosphere of radiant heat about it in which, I knew, no ship, however heat-resistant, could live for more than a moment. On we raced, our cruiser creaking and swaying still from the effects of the collision with the ship we had smashed into, but flashing on with unabated speed.

Behind us, the three gleaming shapes of our pursuers were following with unslackened speed, too, gradually drawing nearer, the two foremost of those ships just behind us, now. Another moment and their death-beams would stab toward us, and though we might destroy one or even two of them the other would surely destroy us before we could turn to it, I knew. The heat, too, of the great star before us was penetrating into our ship, and full before us, not a dozen million miles ahead, glowed the great corona. On we flashed—on—on—and then, just as we were about to burst into the terrible, glowing corona, just as the two ships close behind us sprang closer to stab with their beams toward us, Korus Kan jerked the controls suddenly back, and instantly our ship shot upward in a great vertical rush, while beneath, before they could see and follow our change of course, the two racing oval ships pursuing us had flashed on and into the mighty glare of the corona. Then we glimpsed them shriveling, twisting, vanishing, in the awful heat there, while our own cruiser turned now away from the red sun.

Beneath we saw the single remaining oval ship turning, too, since it had been far enough behind the two to change its course in time to avoid the terrible corona. It seemed to pause, hesitate, and then, as though satisfied that our ship too had met death in the corona with its own two companions, it began to flash backward toward the galaxy's edge, toward the Cancer cluster where the mighty invading fleet had settled. And now, burning for revenge, our own cruiser was slanting back with it and down toward it, as it drove on unsuspectingly beneath. Another moment and we would be above it, would loose our red rays on it before ever it suspected our existence. I was breathing with relief at our escape, now, and heard an exulting cry from Jhul Din as he strode down into the cruiser's hull from the pilot room, to direct the ray-tubes there, but the next moment all our triumph vanished, for from our cruiser's hull, toward its battered prow, there came suddenly a succession of appalling cracks.

Standing suddenly tense we listened, and then, as there came from beneath a prolonged, cracking roar, I heard shouts of fear from our crew, and then Jhul Din had burst up into the pilot room from beneath.

"The cruiser's walls are giving!" he cried. "That collision with the oval ship when we smashed our way out strained and wrenched loose the whole prow and side-walls—the cruiser can't hold together for five minutes more!"

There was a stunned silence in the little room then, a silence in which it seemed that all the disasters that had befallen us were crowding together upon us, overpowering us. This was the end, I knew. Within minutes more the walls about us would collapse and in the infinite cold and emptiness of interstellar space we would meet our deaths. We were hours away from the nearest friendly planet, with all our companion ships destroyed. It was the end, and for a moment I bowed to the inevitable, stood in stunned despair awaiting that end. But then, as my eyes fell upon the oval ship beneath, toward which our collapsing cruiser was still slanting downward, I saw that upon its broad metal back was the round circle of a space-door, like the double space-doors of our own ship, and as I saw that, all the ancient combativeness that has carried men out into the remotest of the galaxy's depths surged up in me, and I wheeled around to the other two.
