There were thousands of them, dark featherless flapping creatures like flying throw rugs. Amid the concerted roar of their wings they made low moaning noises, thrumming like bass strings. They swooped and dove, and the android understood their tactics when he saw a vehicle burst from a Princeton garage and skid down the street. A group of flappers swooped down in a group, battering at the car bodily and enfolding the target within their leathery shapes, smothering it beneath their weight. The android, his energies partially recovered, fired into the fliers, dropping a few, but the car swerved over a curb and smashed into a building. More fliers descended as the first group began to squeeze through shattered windows. Corrosive acid stained the car's finish. The android rose and began firing into the airborne mass, trying to attract their attention.
A cloud dove for him, hundreds at once, and Modular Man increased speed, bearing south, trying to lead them away, dead fliers dropping like leaves as he fired short bursts behind him. More and more of the orbiters were drawn into the pursuit. Apparently the creatures were not very intelligent. Dodging and weaving, staying just ahead of the fluttering cloud, the android soon had thousands of the fliers after him. He came up over a rise, and saw the Swarm host before him. For a moment his sensors were overwhelmed by the staggering input.
An army of creatures were advancing in a curved wave, a sharply angled crescent that pointed north to Princeton. The air was filled with grinding, rending sounds as the Swarm bulldozed its way through a town-houses, trees, office buildings, everything-leveling everything in its path. The android rose, making calculations, the fliers moaning and flapping at his back. The host was moving quickly for doing such a thorough job; the android estimated twelve to fifteen miles per hour.
Modular Man had a good idea of the average size of a Swarm creature. Dividing the vast infrared emission by its component parts, he concluded he was looking at a minimum of forty thousand creatures. More were joining all the time. There were another twenty thousand fliers at least. The numbers were insane.
The android, unlike a human, could not doubt his calculations. Someone had to be informed of what the world was facing. His shoulder-mounted guns swung back to allow for better streamlining and he circled back north, increasing speed. The fliers circled but were unable to keep up. They began to flap back in the direction of Princeton.
Modular Man was over Princeton in a matter of seconds. A thousand or more of the Swarm had penetrated into the town and the android detected the constant smashing of buildings under assault, the scattered crackle of gunfire, and from one location the boom, rattle, and crash of heavier weapons. The android sped for the sound.
The National Guard armory was under siege. One of the serpent creatures, torn apart by explosive rounds, was writhing on the street in front, thrashing up clouds of fallen tear gas. Dead predators and human bodies dotted the landscape around the building. An M60 tank was overturned on the concrete out front; another blocked an open vehicle-bay door, flooding the approach with infrared light. Three Guardsmen in riot gear, complete with gas masks, stood on the tank behind the turret. The android fired eight precisely placed shots, killing the current wave of attackers, and flew past the tank, lighting next to the Guardsmen. They gazed at him owlishly through their masks. Behind were a dozen civilians with shotguns and hunting rifles, and behind them about fifty refugees. Somewhere in the building, revving engines boomed.'
"Who's in charge?"
A man wearing the silver bars of a lieutenant raised his hand. "Lieutenant Goldfarb," he said. "I was duty officer. What the hell's going on?"
"You'll have to get these people out of here. Aliens from outer space have landed."
"I didn't figure it was Chinese." His voice was muffled by the gas mask.
"They're coming this way from Grovers Mills."
One of the other Guardsmen began to wheeze. The sound was barely recognizable as laughter. "Just like War of the Worlds. Great. "
"Shut the hell up." Goldfarb stiffened in anger. "I've only got about twenty effectives here. Do you think we can hold them at the Raritan Canal?"
"There are at least forty thousand of them."
Goldfarb slumped against the turret. "We'll head north, then. Try to make Somerville."
"I suggest you move quickly. The fliers are coming back. Have you seen them?"
Goldfarb gestured to the sprawled bodies of a few of the flappers. "Right there. Tear gas seems to keep them out."
"Something else coming, boss." One of the soldiers raised a grenade launcher. Without a glance Modular Man fired over his shoulder and downed a spider-thing.
"Never mind," the soldier said.
"Look," Goldfarb said. "The governor's mansion is in town. Morven. He's our commander in chief, we should try to get him out."
"I could make the attempt," the android said, "but I don't know where the mansion is." Over his shoulder he disposed of an armored slug. He looked at Goldfarb. "I could fly with you in my arms."
"Right." Goldfarb slung his M16. He gave orders to the other National Guardsmen to get the civilians into the armored cars, then form a convoy.
"Without lights," the android said. "The fliers may not perceive you as readily."
"We've got IR equipment. Standard on the vehicles."
"I'd use it." He thought he was getting his contractions right.
Goldfarb finished giving his orders. National Guard troops appeared from other parts of the building, dragging guns and ammunition. Tracked vehicles were revving. The android wrapped his arms around Goldfarb and raced into the sky.
"Air-borne!" Goldfarb yelled. Modular Man gathered this was an expression of military approval.
A massive rustling in the sky indicated the fliers returning. The android dove low, weaving among shattered houses and torn tree-stumps.
"Hol-ee shit," Goldfarb said. Morven was a ruin. The governor's mansion had fallen in on its foundations. Nothing living could be seen.
The android returned the Guardsman to his command, on the way disposing of a group of twenty attackers preparing to assault the Guard headquarters. Inside, the garage was filled with vehicle exhaust. Six armored personnel carriers and two tanks were ready. Goldfarb was dropped near a carrier. The air was roaring with the sound of fliers.
"I'm going to try to lure the fliers away," the android said. "Wait till the sky is clearing before you move."
He raced into the sky again, firing short bursts of his laser, shouting into the darkening sky. Once more the fliers roared after him. He led them toward Grovers Mills again, seeing the vast crescent of earthbound Swarm advancing at their steady, appalling rate. He doubled back, stranding the fliers well behind him, and accelerated toward Princeton. Below, a few fliers rose after him. It looked as if they had been dining on the corpse of a man wearing complicated battle armor. The same armor Modular Man had seen at Aces High, now stained and blackened with digestive acid.
In Princeton he saw Goldfarb's convoy making its way along Highway 206 in a blaze of infrared light and machinegun fire. Refugees, attracted by the sound of the tanks and APCs, were clinging to the vehicles. The android fired again and again, dropping Swarm creatures as they leaped to the attack, his energies growing low. He followed the convoy until they seemed out of the danger area, when the convoy had to slow in a vast traffic jam of refugees racing north.
