A final roll call, by units, companies, divisions and functions, established the fact that all our forces were in position. No Han activity was reported, and no Han broadcasts indicated any suspicion of our expedition. Nor was there any indication that the Sinsings had any knowledge of the fate in store for them. The idling of rep-ray generators was reported from the center of their camp, obviously those of the ships the Hans had given them--the price of their treason to their race. Again I gave the word, and Hearn passed on the order to his subordinates. Far below us, and several miles to the right and left, the two barrage lines made their appearance. From the great height to which we had risen, they appeared like lines of brilliant, winking lights, and the detonations were muffled by the distances into a sort of rumbling, distant thunder. Hearn and his assistants were very busy: measuring, calculating, and snapping out ultrophone orders to unit commanders that resulted in the straightening of lines and the closing of gaps in the barrage. The White Division Boss reported the utmost confusion in the Sinsing organization. They were, as might be expected, an inefficient, loosely disciplined gang, and repeated broadcasts for help to neighboring gangs. Ignoring the fact that the Mongolians had not used explosives for many generations, they nevertheless jumped at the conclusion that they were being raided by the Hans. Their frantic broadcasts persisted in this thought, despite the nervous electrophonic inquiries of the Hans themselves, to whom the sound of the battle was evidently audible, and who were trying to locate the trouble. At this point, the swooper I had sent south toward the city went into action as a diversion, to keep the Hans at home. Its "kite-tail" loaded with long-range gunners, using the most highly explosive rockets we had, hung invisible in the darkness of the sky and bombarded the city from a distance of about five miles. With an entire city to shoot at, and the object of creating as much commotion therein as possible, regardless of actual damage, the gunners had no difficulty in hitting the mark. I could see the glow of the city and the stabbing flashes of exploding rockets. In the end, the Hans, uncertain as to what was going on, fell back on a defensive policy, and shot their "hell cylinder," or wall of upturned disintegrator rays into operation. That, of course, ended our bombardment of them. The rays were a perfect defense, disintegrating our rockets as they were reached. If they had not sent out ships before turning on the rays, and if they had none within sufficient radius already in the air, all would be well. I queried Garlin on this, but he assured me Yellow Intelligence reported no indications of Han ships nearer than 800 miles. This would probably give us a free hand for a while, since most of their instruments recorded only imperfectly or not at all, through the death wall.
