"You're all right?" asked Tommy. At Evelyn's speechless nod, he put his hand heavily on her shoulder. "I'm glad," he managed to say. "Put on that gas mask. Hell's going to pop in a minute." He watched, every muscle tense. There was confusion about the city gate. Ground vehicles, loaded with foodstuffs, poured out of the gate and back toward the jungle. Other vehicles with improvised enlargements to their carrying platforms--making them into huge closed boxes--rolled up to the gate. The loaded vehicles rolled back and back and back, and ever more apparently empty ones crowded about the city gate waiting for admission. Then there was a sudden flare of intolerable light. A wild yell arose. Clouds of steam shot up from the ready steam guns. But the circling air fleet turned as one ship and plunged for the city. The leaders began to drop smoking things that turned into monstrous pillars of prismatically-colored mist. A wave of deadly vapor rolled over the ramparts of the city. And then there was a long-continued ululation and the noise of battle. Ragged Men, hidden in the jungle, had swarmed upon the walls with ladders made of jungle reeds. They came over the parapet in a wave of howling madness. And they surged into the city, flinging gas bombs as they came. CHAPTER X _The Fight_ The city was pandemonium. Tommy, looking down from his post of command, swore softly under his breath. The Death Mist was harmless to the defenders of Yugna as a gas, because of their gas masks. But it served as a screen. It blotted out the waves of attackers so the steam guns could not be aimed save at the shortest of short ranges. His precautions were taking effect, to be sure. Two thirds of the attackers were Ragged Men drawn from about half the surviving cities, and against such a horde Yugna could not have held out at all but for his preparations. Now the defenders took a heavy toll. Swarms of men came racing toward the open gate, their truncheons aglow in the sunlight. The ring of Death Mist was contracting as if to strangle the city, and it left the ramparts bare again. And from more than one point upon the battlements the roaring clouds of steam burst out again. A dozen guns concentrated on the racing men of Rahn, plunging from the jungle to enter by the gate. They were racing forward, without order but at top speed, to share in the fighting and loot. Then streams of metal balls tore into them. The front of the irregular column was wiped out utterly. Wide swathes were cut in the rest. The survivors ran wildly forward over a litter of dead and dying men. Electric-charge weapons sent crackling discharges among them. Their contorted figures reeled and fell or leaped convulsively to lie forever still where they struck. And then the steam guns turned about to fire into the rear of the men who had charged past them.
