But this was not the main battle. The main battle was hidden under the Death-Mist cloud, concentrated in a vast thick mass in the very center of the city. Tommy watched that grimly. Perhaps eight thousand men had assailed the city. Certainly two thousand of them were represented by the still or twitching forms in queer attitudes here and there, in single dots or groups. There were seven hundred corpses before the city gate alone, where the steam guns had mowed down a reinforcing column. And there were others scattered all about. The defenders had lost heavily enough, but Tommy’s defense behind the line of the ramparts was soundly concentrated in strong points, equipped with steam guns and mostly armed with thermit-throwers as well. From the center of the city there came only a vast, unorganized tumult of battle and death.
Then a huge winged thing came soaring down past Tommy’s tower. It landed with a crash on the roofs below, spilling its men like ants. Tommy strained his eyes. There was a billowing outburst of steam from the tower where Denham had been working the night before. A big flier burst into the weird bright flame of the thermit fluid. It fell, splitting apart as it dropped. Again the billowing steam. No result—but beyond the city walls showed a flash of thermit flame.
“Denham!” muttered Tommy. “He’s got a steam cannon; he’s shooting shells loaded with thermit! They smash when they hit. Good!”
He dispatched a man with orders, but a messenger was panting his way up as the runner left. He thrust a scribbled bit of paper into Tommy’s hand.
“I’m trying to bring down the ship that’s controlling the Death Mist. I’ll shell those devils in the middle of town as soon as our controls can handle the Mist.
Denham.”
Tommy began to snap out his commands. He raced downward toward the street. Men seemed to spring up like magic about him. A ship with one wing aflame was tottering in mid-air, and another was dropping like a plummet.
Then Tommy uttered a roar of pure joy. The huge globe of beautiful, deadly vapor was lifting! Its control-ship was shattered, and men of the Golden City had found its setting. The Mist rose swiftly in a single vast globule of varicolored reflections. And the situation in the center of the city was clear. Two towers were besieged. Dense masses of the invaders crowded about them, battering at them. Steam guns opened from their windows. Thermit-throwers shot out flashes of deadly fire.
Tommy led five hundred men in savage assault, cleaving the mass of invaders like a wedge. He cut off a hundred men and wiped them out, while a rear guard poured electric charges into the main body of the enemy. More men of Yugna came leaping from a dozen doorways and joined them. Tommy found Smithers by his side, powder-stained and sweat-streaked.
“Miss Evelyn’s all right?” Smithers asked in a great calm.
“She is,” growled Tommy. “On the top floor of a tower, with a hundred men to guard her.”
“You didn’t look at the Tube I made,” said Smithers impassively; “but I turned on the steam. Looks like it worked. It’s ready to go through, anyways. It’s the same place the other one was, down in that cellar. I’m tellin’ you in case anything happens.”
He opened fire with a magazine rifle into the thick of the mob that assailed the two towers. Tommy left him with fifty men to block a highway and led his men again into the mass of mingled Ragged Men and Rahnians. His followers saw his tactics now. They split off a section of the mob and fell upon it ferociously. There were sudden awful screams. Thermit flame was rising from two places in the very thick of the mob. It burst up from a third, and fourth, and fifth…. Denham, atop his tower, had the range with his steam cannon, and was flinging heavy shells into the attackers of the two central buildings. And then there was a roaring of steam and a ground vehicle came to a stop not fifty feet away. A gun crew of Yugnans had shifted their unwieldy weapon and its insulated steam boiler to a freight-carrying vehicle. Now the gunner pulled trigger and traversed his weapon into the thick of the massed invaders, while his companions worked desperately to keep the hopper full of projectiles.
The invaders melted away. Steam guns in the towers, thermit projectiles from the cannon far away: now this…. And the concealing cloud of Death Mist was rising still, headed straight up toward the zenith. It looked like a tiny, dwindling pearl.
The assault upon Yugna had been a mad one, a frantic one. But the flight from Yugna was the flight of men trying to escape from hell. Wild panic characterized the fleeing men. They threw aside their weapons and ran with screams of terror no whit less horrible than their howls of triumph had been. And Tommy would have stopped the slaughter, but there was no way to send orders to the rampart gunners in time. As the fugitives swarmed toward the walls again, the storms of steam-propelled missiles mowed them down. Even those who scrambled down to the ground outside and fled sobbing for the jungle were pursued by hails of bullets. Of the eight thousand men who assailed Yugna, less than one in five escaped.
Pursuit was still in progress. Here and there, through the city, the sound of isolated combats still went on. Denham came down from his tower, looking rather sick as he saw the carnage about him. A strong escort brought Evelyn. Aten was grinning proudly, as though he had in person defeated the enemy. And as Evelyn shakingly put out her hand to touch Tommy’s arm—it was only later that he realized he had been wounded in half a dozen minor ways—a shadow roared over their heads. The crackle of firearms came from it.
“Jacaro!” snarled Tommy. He leaped instinctively to pursue. But the flying thing was bound for a landing in an open square, the same one which not long since had seen the heaviest fighting. It alighted there and toppled askew on contact. Figures tumbled out of it, in torn and ragged garments fashioned in the style of the very best tailors of the Earth’s underworld.
Men of Yugna raced to intercept them. Firearms spat and bellowed luridly. In a close-knit, flame-spitting group, the knot of men raced over fallen bodies and hurtled areas where the pavement had cooled to no more than a dull-red heat where a thermit shell had struck. One man, two, three men fell under the small-arms fire. The gangsters went racing on, firing desperately. They dived into a tunnel and disappeared.
“The Tube!” roared Smithers. “They’ goin’ for the Tube!”
He plunged forward, and Tommy seized his arm.
“They’ll go through your Tube,” he said curtly. “It looks like the one they came through. They’ll think it is. Let ’em!”
Smithers tried to tear free.
“But they’ll get back to Earth!” he raged. “They’ll get off clear!”
The sharp, cracking sound of a gun-cotton explosion came out of the doorway into which Jacaro and his men had dived. Tommy smiled very grimly indeed.
“They’ve gone through,” he said drily, “and they’ve blown up the Tube behind them. But—I didn’t tell you—I took a look at your castings. Your pupils were putting them together, ready for the steam to go in, in place of the coils I used. But—er—Smithers! You’d discarded one pair of castings. They didn’t satisfy you. Your pupils forgot that. They hooked them all together.”
