“If we let them through to the city,” he bellowed, turning his horse in place, “it will take another year to see it fall. Stop them and their mounts and weapons are yours, after the khan’s tithe.”

  Those who could hear roared their appreciation of this, and Kachiun raised his right arm and dropped it, signaling the advance. The lines moved forward in perfect formation, the product of months of training on the plain in front of the city when there were no enemies to fight. Officers shouted orders out of habit, but in fact, there were no flaws in the lines. They had at last thrown reins on their enthusiasm for war, even after so long a wait.

  The column had been forty miles south of Yenking when the scouts crossed its path. In the time it had taken Kachiun to return, the slow-moving mass of men and animals had shortened the distance to only twelve. Knowing they had been seen, they had pushed the herds as fast as possible, but there was only so much they could do before they saw the dust cloud of approaching warriors.

  The senior officer, Sung Li Sen, hissed under his breath as he saw the enemy for the first time. He had brought almost fifty thousand warriors north and east from Kaifeng to relieve the emperor’s city. The column was a massive, ponderous thing, with carts and bullocks stretching back along the road. He squinted at the squares of cavalry guarding his flanks and nodded to their commander over the heads of the men. This was a battle long in coming.

  “First position!” he snapped, his command repeated up and down the trudging lines. The orders he had been given were perfectly clear. He would not stop until he reached Yenking. If the enemy engaged him, he was to fight a running battle all the way to the city and avoid being bogged down in skirmishes. He frowned at the thought. He would have preferred a blanket order to crush the tribesmen and worry about resupplying Yenking when they were bones.

  All along the vast snake of men, the soldiers raised long pikes like bristles. Crossbows were cocked by the thousand and Sung Li Sen nodded to himself. He saw the lines of Mongol riders more clearly now, and he braced himself in the saddle, aware that his men looked to him for an example of courage. Few of them had ever traveled this far north, and all they knew of these wild tribesmen lay in the emperor’s demand for support from his southern cities. Sung Li Sen felt his curiosity swell as the riders split along an invisible line, as if his own column was a spearhead they did not dare approach. He saw that they would pass on either side of him and smiled tightly. It suited his orders that they do so. The road lay open to Yenking and he would not stop.

  Kachiun held back the gallop to the last possible moment before leaning into the wind and yelling for his mount to stretch its gait. He loved the thunder that sounded around him as he stood in the stirrups. Over such a distance, they seemed to close slowly, then everything was rushing toward him. His heart pounded as he reached the Chin column and sent his first arrow snapping through the air. He saw the Chin bolts streak out, falling uselessly into the grass. To ride along that endless line was to be untouchable, and Kachiun laughed aloud at the joy of it, sending shaft after shaft. He hardly had to aim with five thousand men on either side of the column, pinching it between them in whipping strikes.

  The Chin cavalry hardly managed to reach full gallop before they were annihilated to a man, smashed from their mounts. Kachiun grinned when he saw not one of the enemy horses had been killed. His men were being careful, especially now they had seen how few riders the Chin had brought to the field.

  When the cavalry were broken, Kachiun chose his targets with precision, aiming at any officer he could see. Within sixty heartbeats, his tuman loosed a hundred thousand shafts at the column. Despite the lacquered Chin armor, thousands were felled in their tracks, with those behind stumbling over them.

  Kachiun could hear the cattle lowing in distress and panic, and to his pleasure, he saw the herd stampede, crushing more than a hundred of the Chin soldiers and breaking a hole in the column before they lumbered off into the distance. He had reached the end of the tail and swung in a little further, ready to double back. Crossbow bolts rattled off his chest, near spent. After the months of tedious training, it was simply wonderful to be riding against an enemy, and better, one who could not touch them but only die. He wished he’d known to bring more quivers. His grasping fingers found the first one empty and began his last fifty shafts, taking a Chin bannerman off his feet with the first.

  Kachiun blinked wind-tears out of his eyes. He had thinned the column enough to see through it to the second five thousand on the eastern flank. They too were riding with impunity, striking at will. Another sixty heartbeats and a hundred thousand arrows followed the rest. The Chin soldiers could not hide and the neat column began to disintegrate. Men who trudged near carts threw themselves under them for protection while their colleagues died around them. A great wail of fear went up from the pikemen, and there were no officers left alive to rally them or keep them on the road to Yenking.

  Kachiun began his second run, this time too far from the column to waste a shot. The lines reversed with the ease that comes of ceaseless hours of drill, and fresh quivers were emptied quickly. Kachiun galloped flat out along the lines, glancing back at the trail of dead they left behind as the column pushed onwards through the storm. The soldiers had kept their discipline, though the pace was slowing. Other men bawled orders in the place of dead officers, knowing that to panic was to invite complete destruction.

  Kachiun grunted to himself in grudging admiration. He had seen many forces who would have broken before this. He reached the head of the column and swung back to the inside line once more, feeling his shoulders burn as he bent the bow again at full speed. He imagined his brother’s face when the straggling remnants reached the welcome they had prepared at Yenking. Kachiun barked a laugh at the thought, his fingers growing sore as he scrabbled in the fast-emptying quiver. Ten more at most, but the column seemed to shudder as panic spread again through the ranks. The crossbow bolts had not stopped and Kachiun had to make a decision. He could feel his men looking to him for the order that would have them draw swords and carve the column to pieces. They were all running low on shafts, and when the last massed volley was fired, their work was over. They knew the orders as well as he did, but still they watched him, hoping.

  Kachiun tensed his jaw. Yenking was far away and Genghis would surely forgive him if he finished the column on his own. He could feel how close they were to breaking. Everything he had learned over the years of war made it something he could almost taste.

  He grimaced, chewing his own cheek as the moment swelled around him. At last he shook his head and drew a wide circle in the air with his fist. Every officer in sight repeated the gesture and the lines fell back from the shattered remnants of the column.

  Kachiun watched his men form up in panting lines, exhilarated. Those who still had arrows loosed them with enormous care, taking men as they pleased. Kachiun could see their frustration as they reined in behind the column and watched it move away from them. Many of them patted the necks of their mounts and stared at their officers, furious at being called back from the killing. It made no sense and Kachiun had to be deaf to the shouts of complaint from all quarters.

  As the column put distance between them, many of the soldiers looked back in terror, convinced they were going to be attacked from behind. Kachiun let a gap open, then walked his pony forward. He ordered the right and left wings to move up, so that they cupped the rear of the column and herded it onwards to Yenking.

  Behind them, they left a trail of dead men over more than a mile, with fluttering pennants and pikes in piles. Kachiun sent a hundred warriors to loot the bodies and dispatch wounded men, but his gaze didn’t leave the column as it made its way to his waiting brother.

  It took until late afternoon for the battered column to sight the city it had come to relieve. By that point, the Chin soldiers who had survived the slaughter walked with their heads down, their spirits broken after so long with death at their backs. When they saw another ten thousand barring th
eir way, fresh men with lances and bows, they sent up a moan of utter misery. The column shuddered again as they hesitated, knowing they could not fight their way through. Without a signal, they halted at last and Kachiun raised a fist to stop his men riding too close. In the gathering gloom, he waited for his brother to approach. He was pleased he had not denied Genghis this moment when he saw him ride apart from the tuman of warriors and come cantering across the grass.

  The dull-eyed Chin soldiers watched him, panting and exhausted at the pace they had been forced to set. The carts of goods had drifted back through the hurrying ranks, left behind while Kachiun peeled men off to investigate the contents.

  In a deliberate show, Genghis judged the mood of the column and rode right along the edge of it. Kachiun heard his men murmur in pleasure at the khan’s display of courage. Perhaps there was still a risk that crossbows might take him from the saddle, but Genghis did not look at the Chin soldiers as he passed, seemingly unaware of the thousands of men turning to watch him from under lowered brows.

  “You have not left me with many, brother,” Genghis said. Kachiun could see he was pale and sweating from the ride. On impulse, Kachiun dismounted and touched his head to his brother’s foot.

  “I wish you could have been there to see the faces of their officers,” Kachiun replied. “We are truly wolves in a world of sheep, brother.”

  Genghis nodded, his weariness preventing him from sharing Kachiun’s light spirits. “I see no supplies here,” he said.

  “They have left them all behind, including as fine a herd of oxen as you will ever see.”

  Genghis perked up at that. “I have not eaten beef in a long time. We will roast them before Yenking and waft the smell of the meat over the walls. You have done well, brother. Shall we finish them?” Both men looked over the grim column of soldiers, now no more than half the original size.

  Kachiun shrugged. “They are too many mouths to feed, unless you will give them the supplies they brought to this place. Let me try to disarm them first, or they could still fight.”

  “You think they will surrender?” Genghis asked. His eyes sparkled at his brother’s suggestion, touched by Kachiun’s evident pride. Of all things, the tribes revered a general who could win with wits rather than force.

  Kachiun shrugged. “Let us see.”

  He summoned a dozen men who could speak the Chin language and sent them out to ride along the column as close as Genghis had himself, offering peace terms if they gave up their weapons. No doubt it helped that the men were near exhaustion after a day of being chased by an enemy who struck with shocking power while remaining untouched. Their morale had been left on the march, and Genghis smiled as he heard the crash of weapons being thrown down.

  It was almost dark before the pikes, crossbows, and swords had been removed from the silent ranks. Genghis had sent fresh quivers by the thousand back to Kachiun, and the Mongols waited in calm anticipation as the sun made the plains gold.

  Before the last light faded, a horn rang across the plain and twenty thousand bows bent. The Chin soldiers screeched in horror at the betrayal, the sound choked off as the volleys struck and struck and struck until it was too dark to see.

  As the moon rose, hundreds of oxen were killed and roasted on the plain, and on the walls of the city, Zhi Zhong tasted his own bitter saliva, filled with a grinding despair. In Yenking, they were eating the dead.

  When the feast was at its height, the spy saw the shaman rise and stagger drunkenly through the gers. He rose like a shadow to follow him, leaving Temuge to sleep off the haunch of bloody beef he had devoured. The warriors were chanting and dancing around the fires, and the drummer boys pounded out a fierce rhythm that hid the small noise of his steps. The spy kept the older man in sight as Kokchu paused to urinate on the path, fumbling blearily at himself and cursing in the darkness as he splashed his feet. The spy lost sight of his quarry as the man slipped into deep darkness between two carts. He did not hurry, guessing the man was going back to the Chin girl he kept as a slave in his home. As he walked he thought what he might say to the shaman. On his last trip to the walls, he heard the lord regent had begun a death lottery in the city, where a member of each peasant family was forced to reach into a clay pot as deep as his arm. Those who pulled out a white tile were butchered to feed the rest. Every day brought scenes of unimaginable pain and grief.

  Lost in thought, he saw a shadow twitch as he came round the edge of a ger and let out a cry of shock and pain as he was knocked back into the side of it. The wicker braces creaked against his back and he could feel a cold blade at his throat, stopping his breath.

  When Kokchu spoke, his voice was low and firm, with no sign of the extravagant drunkenness the spy had witnessed before.

  “You have been watching me all night, slave. And now you follow me home. Hsst!” Kokchu made the sound as the spy raised his hands automatically in fear.

  “If you move, I will cut your throat,” Kokchu whispered into his ear. “Be like a statue, slave, while I search you.” The spy did as he was told, enduring the bony hands as they ran over his body. The shaman could not reach right down to his ankles and still hold the blade to his neck. He did find a small knife and threw it away into the darkness without looking. The one in the boot went undetected and the spy let out a slow breath of relief.

  They stood in complete darkness between the gers, hidden from the moon and the feasting warriors.

  “Why would a slave follow me, I wonder? You come to me for your master’s paste and your little darting eyes are everywhere, your questions so innocent. Are you a spy for Temuge, or another assassin? If you are, you are a poor choice.”

  The spy did not reply, though he set his jaw at the sting to his pride. He knew he had barely glanced at the shaman all evening, and he could only wonder what sort of mind produced such constant suspicion. He felt the knife press more firmly into his neck and blurted out the first words that came to his lips.

  “If you kill me, you will learn nothing,” he said.

  Kokchu remained silent for an age, digesting this. The spy swiveled his eyes in his head to see the man’s expression and found curiosity mingling with spite.

  “What could there be to learn, slave?” Kokchu asked.

  “Nothing you would want overheard,” the spy replied. He ignored his usual caution, knowing his life hung in the moment. Kokchu was quite capable of killing him just to deprive Temuge of a supporter. “Let me speak and you will not regret it.”

  He felt a shove and stumbled forward. Even in the dark, he sensed Kokchu behind him. The spy considered ways of disarming the man without killing him, but forced himself to relax. He put his hands on his head and let Kokchu walk him forward to his ger.

  It took courage to duck low at the doorway with the shaman holding a blade at his back, but the spy had gone too far to pass off his words as a bad joke even then. He knew the offer he had to make. The lord regent himself had met him on the wall on his last report. He took a deep breath and pushed the small door open.

  A girl of great beauty knelt on the floor by the open door. A lamp lit her features as she looked up at him, and the spy felt his chest tighten that such a delicate girl should be made to wait on the shaman like a dog. He hid his anger as Kokchu motioned for her to leave them alone. She exchanged one final glance with her countryman as she turned in the door, and Kokchu chuckled.

  “I think she likes you, slave. I am growing tired of her. Perhaps I will give her to your Chin officers. You could have a turn when they are finished teaching her humility.” The spy ignored the words, taking a seat on a low bed so that his hands dropped naturally near his ankles. If the meeting went sour, he could still kill the shaman and be back at the walls before anyone else found out. That thought gave him a confidence that Kokchu sensed, frowning.

  “We are alone, slave. I do not need you, or anything you have to say to me. Speak quickly, or I will give you to the dogs tomorrow morning.”

  The spy took a long, slow b
reath, preparing words that could mean death by torture before the sun rose. He had not chosen the moment. The bodies in Yenking had done that. Now he was either right about the shaman, or dead.

  He straightened his back and rested one hand on his knee, looking sternly up at Kokchu with a faint expression of disapproval. The shaman glowered at the change in the man, going from frightened slave to a dignified warrior in just a moment.

  “I am a man of Yenking,” the spy said softly. “A man of the emperor.”

  Kokchu’s eyes widened.

  The spy nodded to him. “Now my life is truly in your hands.” A sudden instinct made him take the dagger from his boot and place it on the floor at his feet. Kokchu nodded at the act of faith, but did not lower his own blade.

  “The emperor must be desperate, or mad with hunger,” Kokchu said softly.

  “The emperor is a seven-year-old boy. The general your khan defeated now runs the city.”

  “He sent you here? Why?” Kokchu asked him, genuinely curious. Before the man could speak, Kokchu answered his own question. “Because the assassin failed. Because he wants the tribes to leave before the people starve to death, or burn the city down in riots.”

  “It is as you say,” the spy confirmed. “Even if the general wanted to pay tribute for the city, the black tent is up before the walls. What choice does he have but to hold out for another two years, or even longer?” No trace of the desperate lie showed on the spy’s face. Yenking would fall in another month, three at the most.

  At last Kokchu put away his knife. The spy did not know how to read the action. The lord regent had thrown him to the wolves to make the offer. All he had was an instinct that Kokchu was in the tribes but not of them, a man apart. Such men were ripe for picking, but he knew his life could still be measured in heartbeats. A single spasm of loyalty from the shaman, a single shout, could end it all. Genghis would know he had broken Yenking and the jewel of the empire would be lost forever. The spy felt sweat break out on his skin despite the frozen air. He went on before Kokchu could reply.
