Stretching far away into the night, all around us, lay the two fleets, inextricably mixed and mingled with each other, and incapable of acting in two single units. Flashes of blue lightning burned from the air-boats of the Kanlars, and car after car of the Khluns was going down to death on the ice two miles below. By the light of the flashes, and the ensuing flames, the scene below us was ghastly, the air-boats, filled with brazen-armored guards and bright-robed Kanlars, or with the white-clad Khluns, grappling there in midair, plunging down to destruction, or swooping giddily upon one another. There was a chorus of humming sounds that rose even above the roar of the battle, and here and there the air-boats of the Kanlars were disintegrating and falling, spilling forth their occupants in midair. It was well that the Khluns had constructed their own air-boats of a material immune to their own sound-rays, since mixed as the battle was, many of their cars would have been downed by their own allies' weapons. The battle had met and joined in less than a minute, while we hung above it. So far the fighting had been even, but now a thing occurred that tipped the scale in the Kanlars' favor. Without warning, every air-boat of the Khluns suddenly glowed with misty light. Shouts of surprize and rage came up to us. The cars of the Kanlars were as dark as ever, and now, swooping out of the darkness upon the shining air-boats of the men of Kom, they sent them reeling down in flames by the dozens. "Look!" cried Lantin, pointing up through the window in the car's top. Far above, high over even our own car, were some twenty round, glowing circles of light, a light that was identical with the misty light that glowed from the cars of the Khluns. "The Kanlars!" Lantin shouted. "There are air-boats up there, with apparatus that makes the Khluns' cars shine, while their own remain dark! They must be destroyed, or it is all over with our forces!" I looked around for Kethra, but he was lost to view in the battle that raged below. Nor was there any of our allies' cars around us, so I turned our own time-car and sent it racing up toward those glowing circles above. Straight toward them we sped, with the power opened wide, and I braced myself for the shock. Our car struck the first glowing circle with a staggering shock, and ripped through the air-boat above it as if it were paper. We slanted on up, and looking down, I saw the car we had struck reeling down toward the battle below, broken and afire. I turned our car, hovered like a poised hawk for a second, and then flashed down again on the line of air-boats. A dozen flashes of blue flame burned up toward me, but the tremendous swiftness of our car carried us out of line before they reached us. Flashing down on a long slant, I pointed the car's steel prow toward the center of the line of cars, and this time we plowed across two of them in our resistless, ramming swoop.
