As they did so a racing cruiser struck us a glancing blow from beneath and our ship reeled and spun, throwing those of us in the conning-tower violently to one side. When Hal Kur and I scrambled to our feet the pilot lay motionless on the floor, stunned, and at once I leapt to the controls. That moment in which our ship had been pilotless had driven us up above the battle, which lay stretched below us as a mighty field of circling, striking ships, burned across by pink flame and livid blue light. And now I was slanting our own ship down again, swooping headlong down through space while the hissing rays from our own hull seared down toward the enemy ships below. A wild exultation thrilled through me, now, that sheer joy of battle which will ever last in the heart of man, no matter what centuries of peace are his, and I laughed crazily as we rose and circled and swooped again upon the whirling ships below. Of all the battles in the long history of man's battles, surely this was the most glorious of all. What ancient struggles on earth, or on the seas, or between the planets themselves, could equal this mighty grappling of two fleets in the void between the stars, with a mighty sun at their backs and the fate of a universe at stake?

But now, as our cruiser soared again above the fighting ships, I saw that the craft of the globe-men were perishing in increasing numbers, assailed by the blue rays from our own. They seemed to halt, waver for a moment, and then each of the globe-men's cruisers had ceased fighting and had suddenly dropped down a full hundred miles, massing together there and racing away toward Alto. They were in flight!

* * *

I had no need to command a pursuit, for at sight of the fleeing craft our own ships turned and leapt eagerly after them, my own cruiser in the van. Swiftly our speed mounted, until the two fleets were flashing toward Alto at full speed, the enemy ships managing to keep just out of striking distance ahead of us, while we strained our generators to the utmost to close the gap between us. On and on they fled, at the speed of light, with our own fleet close at their heels, on toward the crimson sun ahead, which filled half the sky as we raced toward it. Suddenly a black blot appeared against that sun, largening with terrific speed, and in a moment the fleeting cruisers ahead had disappeared inside it, vanished inside the great ether-cavity which loomed now before ourselves. But our own ships never faltered, speeding straight on, and in a second we, too, were plunging into darkness unutterable as we raced straight into the vast ether-cavity after the fleeing ships. The droning of our generators ceased and we drifted for a torturing moment through the blackness, then burst out again into the red glare of the great sun ahead. And ahead still fled the globe-men's cruisers, heading directly toward their own sun.

Straight after them we raced, speeding over the great sun in turn. Then, just when the greater part of our fleet was flashing directly above the sun, the humming of our generators faltered and died. And instantly our ship was falling, plunging headlong down into the fiery ocean of Alto, ten million miles beneath!

The ships of our fleet were falling with us, like wind-tossed leaves, and now I cried out and pointed upward, even as we whirled down to the fiery death below. Far, far above there hung a little group of cruisers from which broad rays of purple light were stabbing down toward us, bathing our ships in a weird glow. "They've trapped us!" I cried despairingly. "Those ships-that purple ray-it's neutralizing the vibrations of our generators-they led us over this sun and we're falling-"

Below yawned the fiery ocean of red flame that was Alto, stretching from horizon to horizon, its tongues and prominences licking hungrily up toward us. Even through the super-insulation of the cruiser's walls we felt the growing, stifling heat of the sun below. And then I cried out and pointed upward once more. A score of cruisers at the tail of our fleet had escaped the fate of the rest of us by swerving aside in time, and instantly they had turned and slanted upward, then circled once and plunged down toward the hovering ray-ships. They never even used the blue ray but made sure of their enemies by their own deaths, plunging into the enemy cruisers in a score of swift, shattering collisions, and then the purple rays around us had vanished, while the shattered wrecks above whirled down into the crimson sun beneath us. With the vanishing of the rays our generators took up again their familiar humming drone, and the ships of our fleet slanted sharply up, to escape the fiery doom below.

The remaining ships of the globe-men's fleet had disappeared, now, and glancing at our time-dials I gave an order through the telestereo. Our fleet, still over five hundred cruisers strong, sped away from the great sun toward the buff-colored little ball that was its inmost planet. Swiftly its color deepened again to crimson as we arrowed down toward it, and I glanced anxiously again at the time-dials, for less than a quarter-hour remained now in which to get the ray-tube in action on the whirling sun behind us. Meteorlike our ships split the air of the red planet as we shot across its surface, and in a moment we were slanting down toward the city of the globe-men, toward the massed black roofs and streets above which loomed the mighty tower.

As we dropped down toward it there rose to meet us fully fifty star-cruisers like our own, the last remnants of the globe-men's fleet which we had pursued in past their sun. With suicidal determination they flashed straight up toward us, and the next minute was one of swift, terrific battle, the air around us a hell of blue light and pink flame, leaping and burning from ship to ship, while scores of wrecks whirled down into the black city below. Five minutes after that fierce attack we had lost a full hundred of our ships, but we had accounted for the last cruiser of the globe-men, or so we thought.

And now my own flagship and the designated few agreed on were dipping swiftly toward the great tower-platform, where stood the ray-projector which we had fought our way from universe to universe to reach. We were dropping lower, gradually decreasing our speed as we neared the platform, lower, lower…
