Rhaalton desired that Tarrano come out and attack us; but Tarrano would not. We thought perhaps that his offense was inadequate and the one move that he made strengthened that belief. From the city beside the palace, a rectangle of black metal some fifty feet square, rose slowly up. In aspect it was a square, windowless room—a room without a ceiling, open at the top. It rose to a height of five hundred feet and hung level. And from it depended dangling power cables connecting it with the ground.
It was the presence of these cables that made us feel Tarrano was offensively weak. He could not aerially transport his power; hence, for offense he could only rely upon individual batteries which, unless permanently stationed within the city, we knew would have a short range at best. We watched this thing in the air for hours. It did not move; it was soundless. What was its purpose? We could not guess.
And then at last, Geno-Rhaalton ordered us all to the attack.
CHAPTER XXXVII
Battle
I found myself in the air; with my men around me we hovered. Then Georg's command from the instrument room sounded in my ears. I gave the signal; and flying wedge-shaped, we hurled ourselves forward. It was like lying on the air, diving head foremost. The rush of wind sang past me; the ground, a hundred feet below, was a white surface flowing backward.
We were heading for the base of one of Tarrano's barrage projectors. It was mounted within the wall; but the wall itself was protected merely by a fan-shaped subsidiary beam—a weaker barrage over that small area, which by concentrated effort we hoped to break.
From a helan away on both sides of me I saw other wedges of our men coming slanting in to assail the same point; overhead a corps of girls was hovering. Our towers, three of them concentrated here, had risen to a moderate height; their rays were playing upon the threatened area; a steady fountain of sparks showed where they were striking the barrage.
A silent bombardment of flashing beams and sparks. At five hundred feet we added our own smaller rays to the turmoil. If the barrage would break at this point....
