I had counted upon the gradual raising of the wheel by the mirrors, and the tremendous pressure of the hundreds of blower vents, to create the illusion of upward motion. I had counted also on the Old Companions having no more idea than the average man in the street of what actually happened when a space ship took off. When the jet of one of those air vents hit a Neanderthal in the face, he naturally believed it to be the pressure on him of an accelerating motion straight up. And he listened to my broadcast advice, and hit for the bunks. In the first room I found five Neanderthals, all hastily buckling straps across themselves and whining fearfully. I had no more time for mercy, no more inclination for it than had these beasts themselves. Standing in the center of the chamber, I rotated slowly and put a bullet into each ugly face. Then I pounced on the next door. Here there were four, and I suddenly realized I had no more than one bullet left in the revolver. I saw a tommygun beside a bunk. I went for it, knelt, and as my fingers touched it a hand came down on the back of my neck and clutched ferociously. "What you doing?" snarled the Old Companion, lifting me and breathing into my face. Seconds count, seconds.... I knew that after a minute or two of nothing but slow vibration and hurricane breeze, Skagarach or somebody would realize that we were still anchored to Terra. The machine gun was in my hand now. I brought up its muzzle like a lance jerked underhand; the sight tore the beast's chin and lip, turned up his nose and the blood gushed. He recoiled, and I had the weapon in my hands and was stepping back and the chattering began. I made a massacre and went on. There was a scientist among the Old Companions in the next section of the wheel. My illusion must have been _good_--he had strapped himself down too! I sprayed the bunks with leaden death and then roared at him: "Come on! Get a couple of guns and come on! We are taking over this moon!" There were three small chambers next with perhaps a dozen Old Companions shivering in them, and I left those chambers a gore-spattered, reeking ruin. The trembling of the station had slowed now, but the great wind that swept every corner still held the terrified brutes to their straps and beds. I picked up another of the scientists and was joined by the first one. Three of us marched through gleaming steel and chrome, soft white light and antiseptic cleanliness, marched at triple time and dealt death from heated barrels and rattling magazines. We met Nessa and Howard. By now my arms were trembling and the sweat of fury and work was half blinding me. I grinned at them and took time to rub a sleeve across my eyes. "We're winning," I said. Nessa said _ohh_ in a tiny sound of heartfelt thanksgiving. Howard said, "I managed to knock out that broad homely chap," which for some reason struck me as funny, and I passed them, laughing aloud. They followed me.
