On we sped, into the darkness, showing no lights and progressing entirely by compass. Midnight came and passed, while we raced north over the limitless ice-fields, and it began to seem that the Kanlars had no stomach for fighting, now that we had come to attack them. I relieved Lantin at the controls of our car, an hour after midnight, and while he caught a little sleep on the car's floor, we soared smoothly on. The soundless, mighty fleet of air-boats moving steadily along behind me, the monotonous, endless ice below, and the hour after hour that passed without any attack materializing, all of these smoothed down the fears in my mind and lulled me into a temporary lassitude. Half drowsing at the controls of the car, I kept beside the air-boat of Kethra, speeding on into the thick darkness. A glance at a dial told me that we were within a hundred miles of the ice-field's end, and the thought pulled me up somehow from the sudden weariness that had gripped me. Then, a half-mile ahead of me, there was a blinding glare of azure light, a crash that came loudly to my ears even from that distance, and then silence. Through the mighty fleet behind me pulsed a sudden murmuring sound, a whisper of excitement, of expectancy. Lantin, aroused by the crash, jumped up and was at my side. "One of the scouts," I cried to him; "the Kanlars are attacking them, and one was destroyed." Even as I spoke, two more blue flashes jetted out of the darkness ahead, and two air-boats that were racing back to us went down in flames. And then, rushing toward us out of the darkness, came the Kanlar fleet. In the very van of our own fleet, I had a twisted, misty vision of myriad dark shapes that rushed toward us; then, instinctively, I slanted our time-car up and sped up above the battle. We were weaponless, for the sound-rays could not have been used through the walls of our closed car, and so to remain in the very center of the conflict was to invite purposeless destruction. For a moment, the world was filled with crashing sounds, as the two oncoming fleets met, their air-boats crashing here and there into air-boats of the opposing fleet. Then the battle resolved itself with sudden decision into myriad individual combats.
