I gave a telestereo order which flashed through all the fleet, and the huge armada at once arranged itself in the form of a great triangle, a thousand miles wide at its base, with my own cruiser at the triangle's apex. Another order, and the whole vast fleet moved smoothly forward at uniform speed, a speed that mounted quickly as we flashed on through the ether toward the red star ahead with more and more power. The forces of man had gathered themselves and were moving out toward their supreme struggle, sailing out into the interstellar void to grapple with their doom, risking on one great throw of dice the life or death of their universe.
Standing beside our pilot in my flagship's conning-tower, Hal Kur and I peered through the broad fore-window, watching Alto broaden again across the heavens as we raced on toward it. Already it burned in the sky ahead like a great fire, since for four long weeks our fleet had hummed on toward it at highest speed. And now, on the thirtieth day of our flight, its end was at last in sight and we were preparing for our descent on the city of the globe-men.
The plan which we had formed was simple enough. We were to swoop suddenly upon the city, and while it was being attacked by the greater part of our fleet a picked few ships would land upon the great tower-platform, taking possession of the projector there. This our own scientists would train upon Alto in an effort to swerve the sun again from its course. It must be done soon, I knew, for this was the fiftieth day, which was our time-limit; and unless we made our stroke at the great sun before the tenth hour, it had been calculated, Alto would still come close enough to the solar system to cause collisions between its own far-swinging planets and our own sun and worlds, wrecking our solar system. Less than twelve hours remained to us.
Now, as we swept on toward the lurid, immense sun ahead, it was concerning my own courage that I felt most in doubt. The strange defection of Sarto Sen had already unsettled my mind, and as I glanced back through the rear window and glimpsed the far points of light which were all that was to be seen of the great fleet following, I felt with deepening anxiety the immensity of my responsibilities as commander.
How long I brooded there at the window I can not guess, but I was finally aroused by a sudden sharp exclamation from Hal Kur. The big engineer was gazing out through the front telescopic window toward the fiery disk of the sun ahead, amazement on his face. In a moment he beckoned me to his side, and I gazed out with him through the telescopic glass.
Even through the light-repelling shields which had been swung over all our windows the glare of the mighty sun ahead was almost blinding, but my eyes quickly became accustomed to it, and then I gave a catch of in-drawn breath. For I had glimpsed against the crimson disk of Alto a little cloud of dark specks, a tiny swarm that seemed to be growing steadily larger. Breathlessly we watched them, and now we could not doubt that they were drawing nearer, increasing swiftly in size as we raced to meet them. And now they were taking definite shape, seen through our magnifying window, taking shape as smooth, long, fishlike hulls—
Hal Kur whirled around to me, a flame leaping into his eyes. "They're ships!" he cried. "Star-cruisers like our own! Those globe-men—they had our own cruiser!"
Something seemed to check the beating of my own heart at that cry. The cruisers ahead could only come from Alto, could only be manned by the globe-men of Alto's planets. While we lay imprisoned they had studied the design of our own cruiser, had understood and copied it, and during our homeward flight they had built their own great fleet of star-cruisers, guessing that our escape meant an attack on themselves later on. And now they had come out to meet that attack, there in the interstellar void, and the two great fleets were rushing headlong toward a battle that would be fought between the stars!
A moment I stood there, stunned, then turned to the telestereo which transmitted my orders to the fleet. "All ships prepare for battle," I announced, as calmly as possible. "Reduce speed gradually to one hundred miles an hour, holding the same formation until further order."
