Now, though, we were rushing back to strike another deadly blow, and before us, I saw, the thousands of the invading ships were still milling aimlessly there in space, their organization shattered by the smashing blows we had dealt them. With red rays flashing we sped upon them again, but now, from the disorganized mass before us, I saw a score or more of ships rising, flashing upward with immense speed, ships that were not oval like the rest but flat and round and disk-like, ships that I had vaguely glimpsed in our first rush on the enemy fleet and which through all the battle they had kept protected from us at their fleet's center. Now, with all their terrific speed, the disk-ships were flashing upward, and even in the instant that we rushed again upon our enemies they had attained to a great height above us. In that instant I gave them but a glance, since again we were darting upon the mass of oval ships, our own cruiser now toward the rear of our fleet's formation. But in the next moment, even as we flashed on in our swift charge, I saw the score of disk-ships hanging high above suddenly glow and flicker with strange force, the whole great lower side of their big disks alive with a flickering, rippling, viridescent light. And at the same moment I saw the ships of our fleet ahead of us suddenly breaking from their mad charge forward and lifting slowly upward, saw them twisting and turning and reeling but still moving steadily up, toward those score of disk-ships high above, as though pulled upward by a mighty, unseen grip. "Attraction-ships!" I shouted, as I saw what was happening. "Those disk-ships above--they're pulling our cruisers up with some magnetic or electrical attractive force, that affects the metals of our ships but not of theirs!" We were still racing forward, at the rear of our fleet, but as I saw that all the thousands of our cruisers before us, almost, were in the grip of the attractive forces from above, were being pulled helplessly upward, I shouted to Korus Kan, and he shifted the controls swiftly sidewise, sending our cruiser veering away before it came beneath the disk-ships high above and was pulled up likewise. We had escaped for the moment, but now from ahead all the disorganized masses of the oval invading ships had gathered together again and were leaping forward, springing upon our own helpless masses of cruisers as they were pulled resistlessly upward. From all about those masses of twisting, turning cruisers the pale death-beams smote toward them, and only here and there could a few shafts of the red ray answer them, caught as our ships were in that tremendous grip.
