I saw the great metal walls of the space-fort buckling and collapsing beneath that awful impact, and then all the space-fort had collapsed also, like a thing of paper, crushing within itself the serpent-creatures and generators and death-beam tubes it had held. To our left, another score of ships were leaping toward the left-hand fort in the same manner, and as they crashed into it, racing on through a storm of death-beams that swept through them, the left-hand space-fort too had buckled and crumpled and collapsed. At the same moment the last of the thousand serpent-ships before us was falling beneath our force-shafts, and then the great opening lay clear before us, with neither serpent-ships nor space-forts now in sight. We had forced the gates of the serpent-universe! Then, our vast fleet massing together once more, we swept in through the opening, in a long column, into the dying universe. A full two thousand of our hundred thousand ships we had lost in that mad attack on the great gates, but heeded that but little as we flashed now into the serpent-creatures' universe. Through the dead and dying suns we sped, holding to a close-massed formation and moving slowly and cautiously forward. At every moment I expected the great serpent-fleet to burst out upon us from behind some dead or dying sun, for I knew that their allowing us to advance through their universe thus unhindered meant only that they had prepared some ambush for us. Yet as we sped in toward the center of the dying universe, there appeared no single enemy craft about us or on our space-charts, a total absence of all serpent-ships that began to affect our nerves as we drove ever more tensely forward. At last there appeared far ahead the majestic trio of giant, crimson suns that swung at this universe's heart, and as we moved down toward these we knew that at last the final struggle was at hand, since between those suns turned the great world that was the heart of the serpent-civilization. Down toward that world we slanted smoothly, expecting every moment the uprush from it of the great serpent-fleet; yet still were we unchallenged and unattacked as we moved downward. Upon us there leapt no serpent-ships; in space about us, as we sank lower and lower, were no craft other than our own. In breathless silence we watched, sinking down toward the great sphere's surface, until at last we hung at a bare thousand feet above that surface, the mighty city of blue force stretching from horizon to horizon beneath us. And at sight of that city there burst from us wild, stunned cries.
