35: CONFLUENCE

The dust: that was what Josh saw first, a great cloud of it kicked up by racing hooves.

It was about midday. For once it was a clear, bright day, and the rolling bank of dust, perhaps half a kilometer wide, was filled with smoky light, elusive shapes. Then, in Josh’s clear view, they emerged from the dusty glow, shadows at first, coalescing into figures of stocky menace. They were Mongol warriors, identifiable at a glance.

Despite all that had happened to him Josh had found it hard to believe that a Mongol horde, under the control of Genghis Khan himself, was really and truly approaching, intent on killing him. And yet it was so; he could see it with his own eyes. He felt his heart beat faster.

He was sitting in a cramped guard position on the Ishtar gate, looking out over the plain to the east, toward the Mongol advance. With him were Macedonians and a couple of British. The British had decent pairs of binoculars, Swiss-made. Grove had impressed on them the importance of keeping the lenses shielded: they had no idea how much information Genghis Khan had about their situation here in Babylon, but Sable Jones would surely understand the significance of a glinting reflection. The best-equipped of all was Josh, though, for Abdikadir—who had gone off to fight—had bequeathed him his precious NODs, the farsighted night-vision glasses that one wore like goggles.

At the first glimpse of the Mongols, among Macedonians and British observers alike there was an air of tension, and yet of excitement, a palpable thrill. On the next gate, Josh thought he saw the brightly colored chestplate of Alexander himself, come to view this first clash.

The Mongols came in a long line, and seemed to be grouped into units of ten or so. Josh counted the units quickly; the Mongol line was perhaps twenty men deep but two hundred wide—a force of four or five thousand men, just in this first approach.

But Alexander had drawn up ten thousand of his own men on the plain before Babylon. Their long scarlet cloaks billowed in the breeze, and their bronze helmets were painted sky blue, the spines of their crests marked with the insignia of rank.

It started.

The first assault was with arrows. The front ranks of the advancing Mongols lifted complicated-looking compound bows, and fired into the air. The bows were of laminated horn, and could strike accurately over hundreds of yards, as fast as a warrior could pull arrows from his quiver.

The Macedonians had been drawn up into two long files, with the Foot Companions at the center, and the elite Shield Bearers guarding either flank. Now, as the arrows flew, to brisk drumbeats and trumpet peals, they quickly regrouped into a close order, boxlike formation eight men deep. They raised their leather shields over their heads and locked them together, like the formation the Romans had called the turtle.

The arrows fell on the shields with audible thumps. The shell formation held, but it wasn’t perfect. Here and there men dropped, to sharp cries, and there would be a brief hole in the cover, a fast flurry as the wounded man was dragged from the formation, and the shell would close up again.

So men had already started to die, Josh thought.

Perhaps a quarter-mile from the city walls, the Mongols suddenly broke into a charge. The warriors roared, their war drums banged like a pulse, and even the clatter of the horses’ hooves was like a storm. The wave of noise was startling.

Josh didn’t believe he was a coward, but he couldn’t help but quail. And he was astonished at how calmly Alexander’s seasoned warriors held their places. To more trumpet peals and yelled commands—“Synaspismos!”—they broke up their turtle formation and formed their open lines once more, though some kept their shields raised to ward off arrows. They were in a line four deep now, with some troops held in reserve at the back. They were infantrymen facing the Mongols’ cavalry charge, a thin line of flesh and blood was all that stood between Babylon and the oncoming Mongols. But they locked their button shields together and rammed the butts of their long spears in the ground, and foot-long iron blades bristled at the oncoming Mongols.

In the last moments Josh saw the Mongols very clearly, even the eyes of their armored horses. The animals seemed crazed; he wondered what goads, or drugs, the Mongols used to induce their horses to attack packed infantry.

The Mongols fell on the Macedonian lines. It was a brutal collision.

The armored horses battered a way through the Macedonian front line, and the whole formation buckled at the center. But the Macedonians’ rear lines cut at the animals, killing or hamstringing them. Mongols and their horses began to fall, and their rear lines slammed into the stalled advance.

All along the Macedonian line now there was a stationary front of fighting. A stink of dust and metal, and the coppery smell of blood, rose up to Josh. There were cries of rage and pain, and the clash of iron on iron. There were no gunshots, no cannon roars, none of the dark explosive noises of the warfare of later centuries. But human lives were erased with industrial efficiency, all the same.

Josh was suddenly aware of a silvered sphere hovering before him, high over the ground, but almost at his own eye level. It was an Eye. Perhaps, he thought grimly, there were other than human observers here today.

The first assault lasted only minutes. And then, to a trumpet-call, the Mongols suddenly broke away. Those still mounted galloped back from the fray. They left behind a line of broken and writhing bodies, severed limbs, maimed horses.

The Mongols paused in loose order, a few hundred yards from the Macedonian position. They called insults in their incomprehensible language, shot off a few arrows, even spat at the Macedonians. One of them had dragged a wretched Macedonian foot soldier with him, and now, with mocking elaboration, began to carve a hole in the living man’s chest. The Macedonians responded with insults of their own, but when a unit ran forward, weapons raised, their officers roared commands for them to hold their positions.

The Mongols continued to withdraw, still taunting the Macedonians, but Alexander’s soldiers would not follow. As the lull continued, stretcher-bearers ran out from the Ishtar Gate.

The first Macedonian warrior to be brought into Bisesa’s surgery had suffered a leg wound. Ruddy helped her haul the unconscious figure onto a table.

The arrow had been broken and pulled out, but it had passed right through the calf muscle and out the other side of the leg. It didn’t look to have broken any bones, but flaps of muscle tissue spilled out of the raw wound. She stuffed the muscle tissue back into the hole, packed some wine-soaked cloth into it, and then, with Ruddy’s brisk help, bound it up tight. The soldier was stirring. She had no anesthetic, of course, but perhaps, if he woke, fear and adrenaline would keep the pain at bay a while.

Ruddy, working with both hands, wiped sweat from his broad, pale brow onto the shoulder of his jacket.

“Ruddy, you’re doing fine.”

“Yes. And this man will live, will he not? And walk out, scimitar and shield in hand, to die on some other battlefield.”

“All we can do is patch them up.”

“Yes . . .”

But there was no time, no time. The leg wound was just the first of a flood of stretcher-bound invalids that suddenly flowed in through the Ishtar Gate. Philip, Alexander’s physician, ran to meet the flow and, as Bisesa had taught him, began to operate a brisk triage, separating those who could be helped from those who could not, and sending the invalids to where they could best be treated.

She had Macedonian porters take the leg wound away to a casualty tent, and grabbed the next stretcher in line. It turned out to be a fallen Mongol warrior. He had taken a sword blow to his upper thigh, and blood pumped from an artery. She tried to press the edges of the wound together, but it was surely too late, and already the flow was stilling of its own accord.

Ruddy said, “This man shouldn’t have been let in here in the first place.”

Her hands soaked in blood, panting hard, Bisesa stepped back. “There’s nothing we can do for him anyhow. Get him out of here. Next! . . .”

It continued through the early afternoon, a flow of maimed and writhing bodies, and they all worked on until they felt they could work no more, and continued anyhow.

Abdikadir was with the forces outside the walls of Babylon. He had already come close to the fighting, when the Macedonian line had nearly buckled. But he and the British—and Casey, somewhere else in the line—had been kept in the reserves, their firearms concealed under Macedonian cloaks. Their moment would come, Alexander had promised them, but not yet, not yet.

Alexander and his modern advisers had the perspective of a different history to aid them. They knew the Mongols’ classic tactics. The first Mongol assault had been only a feint, intended to draw the Macedonians into a pursuit. They would have been prepared to withdraw for days if necessary, exhausting and dividing Alexander’s forces, until at last they were ready to snap closed their trap. The moderns had told Alexander how the Mongols had once broken an army of Christian knights in Poland by luring them in this way—and in fact Alexander himself had faced Scythian horsemen who used similar tactics. He would have none of it.

Besides, Alexander was playing his own game of concealment, with half his infantry and all his cavalry still hidden inside the walls of Babylon, and with the weapons of the nineteenth and twenty-first centuries still unused. It might work. Though Mongol scouts had been spotted in the countryside around Babylon, it was scarcely possible for spies of Genghis Khan to penetrate the city undercover.

Despite the defenders’ tense anticipation, the Mongols did not come again that day.

As the evening gathered, a great line of campfires could be seen on the horizon, stretching from north to south, as if encircling the world. Abdikadir was aware of muttering among the men at the apparent awesome size of the Mongol force. They might have been more scared, he mused, if they had been told that among the long lines of the Mongols’ yurts had been spotted the unmistakable dome shape of a spacecraft.

But Alexander himself came walking through the camp, with Hephaistion and Eumenes at his side. The King was limping slightly, but his helmet and breastplate of iron gleamed like silver. Everywhere he walked he joked with his men. The Mongols were faking, he claimed. They had probably lit two or three fires for every man they had out in the field—why, they had been known to go into battle with stuffed dummies riding their spare horses, to addle the wits of their enemies. But Macedonians were too sharp to fall for such ruses! And meanwhile Alexander himself had allowed so few fires to be lit that the Mongols would seriously underestimate the strength of those opposing them, as well as never guessing at the Macedonians’ indomitable valor and will!

Even Abdikadir felt his spirit rise as the King passed. Alexander was a remarkable man, he thought—if, like Genghis Khan, a terrible one.

With his Kalashnikov at his side, curled up under his poncho and a coarse British blanket, Abdikadir tried to sleep.

He felt oddly at peace. This confrontation with the Mongols seemed to have focused his own determination. It was one thing to know of the Mongols in the abstract, as a page of long-dust history, and another to see their destructive ferocity in the flesh.

The Mongols had done huge damage to Islam. They had come to the rich Islamic state of Khwa¯rezm—a very ancient nation, stable and centralized since the mid-seventh century B.C. In fact Alexander the Great, on his cross-Eurasian jaunt, had come into contact with it. The Mongols sacked its beautiful cities of Afghanistan and northern Persia, from Herat to Kandahar and Samarkand. Like Babylonia Khwa¯rezm had been built on an elaborate underground irrigation system that had survived since antiquity. The Mongols destroyed this too, and with it Khwa¯rezm; some Arab historians claimed the region’s economy had never recovered. And so on. The soul of Islam had been forever darkened by these events.

Abdikadir had never been a zealot. But now he discovered in himself a passion to put history right. This time Islam would be saved from the Mongol catastrophe, and be reborn. But this wretched war had to be won first—at any cost.

It was comforting, he thought, in the confusion left by the Discontinuity, to have something to do: a goal of unambiguous value to aim at. Or maybe he was just rediscovering his own Macedonian blood.

He wondered what Casey would say to all this—Casey the jock Christian, born in Iowa in 2004, now caught between armies of Mongols and Macedonians, in a time that had no date. “A good Christian soldier,” Abdikadir murmured, “is only ever a klick away from Heaven.” He smiled to himself.

Kolya had lain in his hole in the ground under Genghis’s yurt for three days—three days, blind and deaf and in agonizing pain. And yet he lived. He could even sense the passage of time by the vibration of the feet on the floorboards above him, footsteps coming and going like a tide.

If the Mongols had searched him they would have found the plastic bag of water under his vest, the sips of which had kept him alive so long—and the one other item that this great gamble had been all about. But they had not searched him. A gamble, yes, and it had paid off, at least so far.

He had known far more about the Mongols than Sable ever could, for he had grown up with their memory, eight centuries old yet still potent. And he had heard of Genghis’s habit of sealing enemy princes under the floor of his yurt. So Kolya had leaked what information he could to Casey, knowing he would be caught; and, once caught, he had let the treacherous Sable manipulate the Mongols into granting him this “merciful” release. All he had wanted was to be here in the dark, still alive, holding the device he had made, just a meter or so from Genghis Khan.

The Soyuz had not carried any grenades, which would have been ideal. But there were unused explosive bolts. The Mongols would not have recognized what he had brought out of the spacecraft, even had they been watching him carefully. Sable would have known, of course, but in her arrogance she had assumed Kolya was an irrelevance, not capable of hindering her own ambitions. Disregarded, it had been a simple matter for Kolya to rig up a simple trigger, and to conceal his improvised weapon.

He had to wait for the right time to strike. That was why he had had to wait, in the dark and the agony. Three days—it was like surviving three days beyond his own death. But how odd that his body kept functioning, that he had to urinate and even defecate, as if the body thought his story had an epilogue. But these were like the twitches of a fresh corpse, he thought, of a manikin, meaningless in themselves.

Three days. But Russians were patient. They had a saying: that the first five hundred years are always the worst.

First light gathered. The Macedonians started to move around, coughing, rubbing their eyes, urinating. Abdikadir sat up. The pink-gray of the brightening sky was oddly beautiful, scattered sunlight against volcano ash clouds, like cherry blossom scattered on pumice.

But he had only moments of peace after waking.

First and last light are the most dangerous times for a soldier, when the eye struggles to adjust to fast-changing light. And, in that moment of maximum vulnerability, the Mongols struck.

They had approached the Macedonian positions in silence. Now the great naccara called out, their camel-borne war drums, and the Mongols surged forward, screaming wildly. The sudden eruption of noise was bloodcurdling, as if some immense force of nature was approaching, a flood or a landslide.

But the Macedonians’ trumpet peals followed only a heartbeat later. Soldiers rushed to their positions. There were brisk commands in the Macedonians’ harsh dialect: Form up, hold your position, hold the line! The Macedonian infantry, eight deep, made a wall of hardened leather and iron.

Alexander had, of course, been prepared. Anticipating this assault, he had let his foe approach as close as he dared. Now was the time to spring his trap.

Abdikadir took his place, three ranks back from the front. To either side were nervous Tommies. Catching their glances, Abdikadir forced a smile and raised his Kalashnikov.

He got his first good look at a Mongol warrior through a gun sight.

The Mongols’ heavy cavalry was at the center of the charge, with the light cavalry following behind. They wore body armor made of strips of buffalo leather, and metal helmets with leather guards over their necks and ears. Each man was loaded with weapons: two bows, three quivers, a lance with a vicious-looking hook on the end, an axe, a curved saber. Even the horses were armored, with broad leather sheets that guarded their sides, and metal caps on their heads. The Mongols, carapaced, bristling with weapons, looked more insectile than human.

But they weren’t having it all their own way. At a trumpet peal, archers popped up over the parapets of the walls of Babylon, and arrows hissed through the air, over Abdikadir’s head, thudding into the advancing Mongols. When a rider fell there would be a tangle, briefly disrupting the charge.

Now more arrows fell, ablaze, their tips dipped in pitch. They were aimed at flame pits, bales of hay soaked in pitch in the ground. Soon great pockets of flame and smoke were bursting up beneath the Mongols. Men screamed, and their horses shied and refused. But, though the grit of casualties slowed the Mongol advance, it did not halt it.

And once again the Mongol heavy cavalry slammed into the Macedonians.

All along the line the Macedonians fell back. The momentum of the Mongols’ charge, and the sheer ferocity with which the horsemen wielded their swords and maces, made that inevitable.

Abdikadir, now only a meter or so from the worst of the fighting, saw rearing horses, flat Mongol faces looming above the struggling crowd, men fighting and dying. He could smell blood, dust, the sweat of terrified horses—and, even now, a rank, buttery stink that could only be the Mongols themselves. The sheer density of men and animals, the roar of ten thousand voices, made it difficult to fight, even to raise a weapon. As blades hissed in the air, blood and body parts flew in scenes of almost absurd, impossible carnage, and gradually the screams of rage turned to howls of pain. More pressure came when the Mongol light cavalry followed up their heavy counterparts, pressing forward where the heavy cavalry had made room, jabbing with their swords and javelins.

But Alexander struck back. Brave infantrymen rushed from the back of the Macedonian line carrying long hooked lances; if the lance missed, the hook could dismount a warrior. Mongols fell, but the Macedonian infantrymen were cut down like flowers before a scythe.

Now, through the clamor, a Macedonian trumpet sounded a clear peal.

At the center of the field, just before Abdikadir, the surviving Macedonian front ranks pulled back, melting through the ranks behind them, leaving their wounded and dead. Suddenly there was nothing left, nothing between Abdikadir and the most ferocious horseback warriors who had ever lived.

The Mongols, startled, their horses shying, hesitated for a second. One immense man, short but wide like a bear, stared into Abdikadir’s eyes and raised a stubby mace that was already dripping with blood.

Captain Grove was at Abdikadir’s side. “Fire at will!”

Abdikadir raised his Kalashnikov and pulled the trigger. The Mongol’s head exploded into a mist of blood and bone, his metal cap hurled absurdly into the air. His horse bolted, the headless body sliding from the saddle into the pressing crowd.

All around Abdikadir the British fired into the mass of Mongols, antique British Martini-Henrys and Sniders making precise coughs against the clatter of the Kalashnikovs. Men and horses disintegrated before the withering hail of bullets. Grenades flew. Most of them were just flashbangs, but that was enough to terrify the horses and at least some of the warriors. But one exploded under a horse. The animal seemed to burst, and its rider, screaming, was hurled away.

One grenade landed too close to Abdikadir. The blast was like a punch to the stomach. He fell backward, his ears ringing, his nose and mouth filled with the sour, metal taste of blood, and the chemical tang of the ignition. He felt somehow dislocated, as if he had been knocked through another Discontinuity. But if he was down, a corner of his mind told him, there was a hole in the line before him. He raised his rifle, fired without looking, and struggled to his feet.

The order came to advance. The line of British strode forward, firing continually.

Abdikadir moved ahead with them, snapping a new magazine into his weapon as he did so. There was no open ground; he had to climb over earth littered by corpses and body parts, in places slippery with entrails. He even had to step onto the back of a wounded man, who screamed in agony, but there was no other way.

It was working, he thought at first. To left and right, as far as he could see, where they were not dying in their saddles, the Mongols were falling back, their weapons unable to match the firearms of six hundred years and more after their time.

But now Abdikadir heard a high-pitched voice—a woman’s voice—and some of the Mongols clambered off their horses. They actually advanced toward the gunfire, using the bodies of their comrades and their horses as cover. Abdikadir recognized the tactics—scan for threats, move, take cover, scan again. They were using their bows, the only weapon they had that could match the guns’ range, and took turns to cover each other as they made their way forward: a maneuver called pepperpotting. And as they fired, Macedonian screams and a torrent of fluent Geordie oaths told Abdikadir that some arrows were striking home.

These Mongols had been trained to withstand gunfire, he realized. Sable—it had to be, just as they had feared. His heart sank. He snapped in another magazine, and fired again.

But the Mongols were closing. Abdikadir and the other riflemen had been assigned a shield bearer each, but these were being brushed aside. One horseback rider almost got through to Abdi, and he had to swing the rifle, using the butt as a club. He got a lucky hit on the man’s temple, and the Mongol reeled back. Before he could recover Abdikadir had shot him dead, and was looking for the next target.

From his elevated position on the Ishtar Gate Josh could see the great sweep of the battle. Its bloody core was still the slab of struggling men and animals, directly before the gate, where the Mongol heavy cavalry had collided with Alexander’s Foot Companions. The Eyes were everywhere, like floating pearls above the heads of the struggling warriors.

The heavy cavalry was the Mongols’ most powerful instrument, designed to smash the enemy’s strongest forces in a single blow. It had been hoped that a sudden assault with gunfire would do enough damage to the heavy cavalry to blunt that blow. But for whatever reason the Mongols had not fallen back as had been hoped, and the armed troops were getting bogged down.

This was bad news. There had only been three hundred British troops in Jamrud, after all. Their numbers were no match for the Mongols, and even if every single bullet took a Mongol life, Genghis’s troops would surely overwhelm them at last, through sheer numbers.

And now the Mongols threw more cavalry around the wings of the battlefield to envelop the enemy. This was again expected—it was a classic Mongol maneuver called the tulughma—but its sheer ferocity, as the new units smashed into the Macedonians’ flanks, was staggering.

But Alexander wasn’t done yet. Trumpets pealed out again from the city walls. With a great clang, gates were thrown open, and the Macedonian cavalry at last rode out into the field. Even as they emerged they were in their tight wedge formation. At a glance Josh could see how much more skillful these horsemen of ancient times were than the Mongols. And, at the head of the Companions who rode out from the right-hand side, Josh recognized the bright purple cloak and white-plumed helmet of Alexander himself, a panther skin thrown over his saddle cloth, as ever leading his men to glory or death.

The Macedonians, fast, agile, and tightly disciplined, wheeled to cut into the Mongol flank like a scalpel. The Mongols tried to turn, but, compressed now between the stolid Macedonian infantry and the Companions, their movements were constricted, and the Macedonians began to jab at their unprotected faces with their long wooden spears. It was another classic tactic, Josh knew—a battle formation perfected by Alexander the Great, yet inherited from his father before him, with cavalry on the right delivering the killer blow, and the central infantry following up with its dogged pressure.

Josh was no advocate of war. But he saw a kind of elation in the eyes of warriors on both sides as they hurled themselves into the fray: a kind of release that the moment in which all inhibitions could be shed was here at last, and a sort of joy. Josh felt a deep visceral thrill as he watched this ancient, brilliant maneuver unfold before his eyes—even as men fought and died in the dirt below, each one a unique life snuffed out. This is why we fight wars, we humans, he thought; this is why we play this game with the highest of stakes: not for profit, or power, or territory, but for this intense pleasure. Kipling is right: war is fun. It is the dark secret of our kind.

Perhaps that was why the Eyes were here—to enjoy the unique spectacle of the universe’s most vicious creatures dying in the dirt. Josh felt resentment, and a certain squalid pride.

Save for some reserves, nearly all the forces were in the field now. Apart from a few cavalry skirmishes on the fringe, the battle was concentrating into that tight, bloody mass of carnage at the center of the field, where men lashed at each other relentlessly. Still the fire pits burned, throwing up smoke that obscured the action, and still arrows rained down from the walls of Babylon.

Josh could no longer tell which way the advantage of the battle went. It wasn’t a time for tactics now, and the opposing generals, perhaps the greatest of all time, could do no more—save, like Alexander, to swing swords themselves. It was a time to fight, or die.

Bisesa’s medical station was overwhelmed. There was no other word for it.

Working alone, she struggled to save a Macedonian, sprawled unconscious on the table before her, dumped like a carcass in a butcher’s store. He was a boy, no more than seventeen or eighteen years old. But he had taken a javelin thrust to the stomach. She cleaned, padded and patched the wound as best she could, her hands trembling with fatigue. But she knew that what would finish the boy off was the infection caused by the garbage that spear point would have carried in with it.

And still, all around her, the bodies flowed in. Those selected by the triage teams were no longer carried to the town house she had designated as a morgue but were rudely dumped on the ground, where they were piling up, their dark blood staining the Babylonian dirt. Of those selected for treatment, a handful had been patched up and gone back out to fight, but more than half her patients had died on the treatment tables.

What did you expect, Bisesa? she asked herself. You’re no doctor. Your only experienced assistant is an ancient Greek who once shook hands with Aristotle himself. You’ve no supplies, you’re running out of everything from clean bandages to boiled water.

But she knew she had saved some lives today.

It might be futile—the great wave of Mongol aggression might break over the walls and destroy them all—but, for now, she found she really and truly didn’t want this boy with the punctured stomach to die. She dug into the guiltily hoarded contents of her twenty-first century medical kit. Trying to hide her actions from the others, she jabbed a shot of streptomycin into the boy’s thigh.

Then she called for him to be taken away, like all the others. “Next!”

Kolya believed that the Mongols’ expansion was pathological. It was a ghastly spiral of positive feedback, born of Genghis Khan’s unquestioned military genius and fueled by easy conquests, a plague of insanity and destruction that had spread across most of the known world.

Russians especially had reasons to despise the memory of Genghis Khan. The Mongols had struck twice. Great cities grown fat on trade, Novgorod, Ryazan and Kiev, were reduced to boneyards. In those dread moments the heart had been torn out of the country, forever.

“Not again,” Kolya whispered, unable to hear the words himself. “Not again.” He knew Casey and the others would resist the Mongol menace as hard as they could. Maybe the Mongols had made too many enemies in the old timeline; maybe in some transcendent way they were now facing payback.

Of course his own gamble was still to be played out—was his weapon powerful enough, would it even work? But he had confidence in his own technical abilities.

Reaching the target, though, was another matter. He had observed Genghis. Unlike Alexander, Genghis was a commander who had watched battles from the safety of the rear, and retired to his yurt at the close of the day; aged nearly sixty, he was predictable to that degree.

Could Kolya be sure, though, any longer, after three days, quite what time it was? Could he be sure that the heavy tread he sensed now was indeed the man he sought to destroy? His only real regret was that he would never know.

Kolya smiled, thought of his wife, and closed the trigger. He had no eyes, no ears, but he felt the earth lurch.

Abdikadir was back-to-back with a handful of British and Macedonians, fighting off Mongols who swirled around them, most still on horseback, lashing and cutting. His ammunition long exhausted, he had dropped the useless Kalashnikov and fought with bayonet, scimitar, lance, javelin, whatever came to hand, the detritus of dead warriors from ages separated by more than a thousand years.

As the battle had closed around him, at first he had felt as if he had become more alive—as if his life had been reduced to this instant, of blood, noise, intense effort and pain, and all that had gone before was a mere prologue. But as fatigue poisons built up, that sense of vividness had been replaced by a coppery unreality, as if he was on the point of fainting. He had trained for this—the “drone zone,” they called it, a place where the body ignored pain, grew impervious to hot or cold, and a new form of consciousness cut in, a kind of dogged autopilot. But that didn’t make it any easier to bear.

This little group was surviving where others had already been cut down, an island of resistance in a sea of blood across which the Mongols surged at will. He himself had taken blow after blow. But he knew he couldn’t take much more. The battle was being lost, and there was nothing he could do about it.

Over the carnage of the battlefield, he heard the cry of a trumpet, an uneven rhythm played on a war drum. He was briefly distracted.

A mace swung down from the sky, smashing the scimitar from his hand. Pain lanced; he had broken a finger. Unarmed, one-handed, he turned to face a Mongol cavalryman who reared above him, raising the mace again. Abdikadir lunged, his good hand stretched out stiff as a board, and stabbed at the Mongol’s thigh, aiming for a nerve center. The cavalryman stiffened and flopped backward, and his horse stumbled back. Abdikadir got to his knees, found his scimitar in the bloody dirt, and straightened up, panting hard, looking for his next assailant.

But there was none.

The Mongol cavalrymen were wheeling their horses around, turning back toward their distant encampment. As they galloped away, occasionally one would stop to pick up a dismounted comrade. Abdikadir, standing there panting, clutching his scimitar, simply couldn’t take it in. It was as surprising as if a tide had suddenly reversed.

He heard a snapping sound, close to his ear, almost insectile. He knew what that was, but his mind seemed to grind slowly, dredging up the memory. A sonic boomlet. A bullet. He turned to look.

Before the Ishtar Gate there was one exception to the general withdrawal. Perhaps fifty Mongols, packed tight on their horses, charged at the open gate. And somebody in there, somebody in the middle of the charge, was shooting at him.

He dropped the scimitar. The world wheeled, and he found the earth, sodden with blood, reaching up to him.

Bisesa heard the screams and roars, right outside her casualty point. She rushed out of the door to see what was happening. Ruddy Kipling, the whole front of his shirt sticky with blood, followed her.

A pack of Mongol warriors had smashed through the defenders’ lines and pushed into the gate. Macedonians were closing around them like antibodies around an infection, and their officers screamed orders. Though the Mongols slashed hard at those around them, already they were being pulled from their horses.

But a single figure burst from the struggling pack, and ran down Babylon’s processional way. It was a woman. The Macedonians hadn’t noticed her—or if they had, didn’t take her seriously enough to stop her. She was dressed in leather armor, Bisesa saw, but her hair was tied back by a strip of material, bright orange.

“Day-Glo,” Bisesa muttered.

Ruddy said, “What did you say?”

“That has to be Sable. Shit, she’s heading for the temple—”

“The Eye of Marduk—”

“It’s what this has been all about. Come on!”

They ran after Sable down the ceremonial way. Worried-looking Macedonian soldiers rushed past them toward the incursion at the gate, and baffled, terrified Babylonian citizens cowered. Over their heads, Eyes hovered, like strings of CCTV cameras, impassive; Bisesa was shocked by how many there were.

Ruddy was first to the chamber of Marduk. The great Eye still hovered over its puddle of congealed gold. Sable stood before the Eye, panting, her hair disheveled over her Mongol armor, gazing up at a distorted reflection of herself. She raised a hand to touch the Eye.

Ruddy Kipling stepped forward. “Madam, get away from there, or—”

With a single movement she turned, raised a pistol, and shot him. In the ancient chamber the crack of the weapon was loud. Ruddy was hurled backward, slammed against the wall, and slumped to the floor.

Bisesa screamed, “Ruddy!”

Sable had raised the gun to Bisesa. “Don’t try it.”

Ruddy looked up helplessly at Bisesa, his broad brow dotted with sweat, his thick glasses spattered with the blood of strangers. He clutched his hip. Blood gushed from between his fingers. He grinned foolishly. “I’m shot.”

Bisesa longed to go to Ruddy. But she stood still and raised her hands. “Sable Jones.”

“My fame spreads.”

“Where’s Kolya?”

“Dead . . . Ah.” She smiled. “A thought occurs. The Mongols sounded the retreat. There was me thinking it was a coincidence. But you know what must have happened? Genghis Khan is dead, and his sons and brothers and generals are hurrying back for a quriltai to decide who gets the big prize. The Mongols have the social structure of a pack of chimpanzees. But, just like the chimps, when the alpha male falls all bets are off. And Kolya used that against them.” She shook her head. “You have to admire the scrawny little bastard. I wonder how he did it.” The gun in her hand never wavered.

Ruddy groaned.

Bisesa tried not to be distracted. “What do you want, Sable?”

“What do you think?” Sable jerked her thumb over her shoulder. “We could hear this thing’s signal from orbit. Whatever’s going on here, this is the key—to past, present and future—”

“To a new world.”

“Yeah.”

“I think you’re right. I’ve been studying it.”

Sable’s eyes narrowed. “In that case you might be able to help me. What do you say? You’re either with me or against me.”

Bisesa looked directly at the Eye. She let her eyes open wider, and forced a smile. “Evidently it’s been expecting you.”

Sable turned her head. It was a simple trick, but Sable’s vanity had trapped her—and Bisesa had won a single half-second. It took one kick to shatter Sable’s wrist and get the gun out of her hand, another to bring her down.

Panting hard, she stood over the fallen cosmonaut. Bisesa thought she could smell her, a stink of milk and fat, like the Mongols she had fallen in with. “Sable, did you really think the Eye would care about you, and your petty ambitions? May you rot in hell.” She glared up at the Eye. “And you—have you seen enough? Is this what you wanted? Have we suffered enough for you? . . .”

“Bisesa.” It was a groan, barely formed as a word.

Bisesa ran to Ruddy.
