Once more, he daydreamed about ruling his people. The tribes would never accept his brother, Jochi, if he was even the khan’s son at all. Chagatai had done his part in spreading the rumour that Jochi was the result of a rape, many years before. Genghis had allowed the whispers to grow deep roots by his distant manner towards the boy. Chagatai smiled to himself at the memories, allowing his hand to drift to the hilt of his sword. His father had given it to him rather than Jochi, a blade that had seen the birth of a nation. In his most private heart, Chagatai knew he would never take an oath to Jochi.

One of the king’s ministers leaned close to the throne to exchange whispered words. It went on long enough for the ranks of courtiers to wilt visibly in their robes and jewels, but at last the minister retreated. Once more the king spoke, his words translated smoothly.

‘Honoured allies may accept gifts in token of a new friendship, as has been discussed,’ the king said. ‘One hundred thousand sheets of oiled paper have been prepared for you, the labour of many moons.’ The assembled crowd of Koryon nobles murmured at the words, though Chagatai could not imagine why paper would be seen as valuable. ‘Ten thousand silk vests have been sewn and the same weight added in jade and silver. Two hundred thousand kwan of iron and the same in bronze have come from the mines and the guild of metalworkers. From my own stores, sixty tiger skins have been wrapped in silk and made ready to travel with you. Finally, eight hundred cartloads of oak and beech are the gift of the Wang dynasty, in thanks for the victory you have brought to the Koryon people. Go now in peace and honour and count us always as allies.’

Jelme nodded stiffly as the translator finished.

‘I accept your tribute, majesty.’

A slight flush had appeared on his neck. Chagatai wondered if the general would ignore the king’s attempt to save face. Tribute was given to conquerors and Jelme stood in silence for a long time as he considered the king’s words. When he spoke again, his voice was firm.

‘I ask only that six hundred young men between the ages of twelve and sixteen be added to it. I will train them in the skills of my people and they will know many battles and great honour.’

Chagatai struggled not to show his approval. Let them choke on that, with their talk of gifts and honoured allies. Jelme’s demand had revealed the true balance of power in the room and the courtiers were visibly distressed. The silence stretched in the hall and Chagatai watched with interest as the king’s minister bowed close once more. He saw the king’s knuckles whiten as his grip on the armrest tightened. Chagatai was tired of their posturing. Even the smooth-limbed women at the king’s feet had lost their allure. He wanted to get out into the cool air and perhaps bathe in the river before the sun lost its heat.

Yet Jelme did not move a muscle and his glare seemed to make the men around the king nervous. Their darting glances were wasted on the silent warriors as they stood and waited for a certain outcome. The city of Songdo had fewer than sixty thousand inhabitants and an army of no more than three thousand. The king could assume whatever airs he wanted, but Chagatai knew the truth of the situation. When the answer came at last, it was no surprise.

‘We are honoured that you would accept so many young men into your service, general,’ the king said.

His expression was sour, but Jelme responded to the interpreter, mouthing further expressions of goodwill that Chagatai drowned out. His father had called Jelme home after three years of scouting the east. It would be good to see the mountains again and Chagatai could barely restrain his impatience at the thought. Jelme seemed to think this paper would be important, though Chagatai doubted Genghis would value it. In that, at least, his father was predictable. It was a good thing Jelme had demanded silk and hard woods as well. Those things were worth having.

Without an obvious signal, the bell sounded again in the courtyard outside, ending the audience. Chagatai watched the servant girls as they readied their master to stand and fell in behind him. He sighed as the room relaxed subtly around him, taking pleasure in scratching his armpit once more. Home. Jochi would be coming back as well, with Tsubodai. Chagatai wondered how his brother would have changed in three years. At seventeen, he would be fully grown and no doubt Tsubodai had trained him well. Chagatai cracked his neck with his hands, relishing the challenges to come.

In the southern half of Chin lands, warriors of the third army of Genghis were drinking themselves senseless. At their backs, the citizens of Kaifeng waited behind high walls and gates, already despairing. Some of the Chin had accompanied the emperor himself as he had come south from Yenking three years before. They had seen the smoke in the northern sky as that city burned. For a time, they thought the Mongols had passed them by, but then the army of Khasar came after them, drawing lines of destruction across the ground like a hot iron across flesh.

The streets of Kaifeng had become lawless even in the heart of the city. Those who had armed guards could climb to the walls and look down on the besieging army. What they saw brought no comfort or hope. To the Chin, even the casual nature of Khasar’s siege was an insult.

On this day, the great khan’s brother was amusing himself with a wrestling competition amongst his men. Khasar’s host of gers lacked a clear pattern and his vast herds of animals wandered aimlessly over the land, only rarely disturbed by the long whips of herdsmen. The Mongols had not so much surrounded Kaifeng as made camp there. To the Chin who hated and feared them, it was galling to see the enemy enjoying games and sports while Kaifeng began to go hungry. Though the Chin were no strangers to cruelty, the Mongols were more callous than they could comprehend. Khasar’s army cared nothing at all for the suffering inhabitants of Kaifeng and only resented them for delaying the fall of the city. They had been there for three months and they showed a terrible, limitless patience.

The emperor’s city of Yenking had fallen to these primitive horsemen. Its great armies had not held them. With that example, no one in Kaifeng had real hope. The streets were ruled by ruthless gangs and only the strong dared go out at all. Food was distributed from a central store, but some days they had nothing. No one could know if the food was running out, or if it had been stolen on the way.

In the camp, Khasar rose to his feet, roaring in excitement with Ho Sa as the wrestler known as Baabgai, the Bear, heaved his opponent up over his head. The vanquished man struggled at first, but Baabgai stood unmoving, beaming like a stupid child at his general. The bets dwindled to a trickle and then nothing. The man he held was so battered and exhausted that he only tugged feebly at Baabgai’s square fingertips.

Khasar had found the wrestler among his Chin recruits, marking him apart immediately for his size and strength. He looked forward to having the massive idiot challenge one of the champions at home. If he judged the wagers well, he could beggar a few men in one match, his brother Temuge among them.

Baabgai waited impassively for Khasar’s order. Few others could have supported a grown warrior for so long and Baabgai’s face was pink and shiny with sweat.

Khasar stared through the big wrestler, his thoughts returning to the message from Genghis. The scout his brother had sent still stood where Khasar had placed him hours before. Flies were sucking at the salt on the scout’s skin, but the young man dared not move.

Khasar’s good mood vanished and he gestured irritably to his wrestling champion.

‘Break him,’ he snapped.

The crowd took a sharp breath as Baabgai dropped suddenly to one knee, bringing his opponent down on the outstretched thigh. The crack of a broken spine sounded across the clearing and all the men roared and exchanged betting tokens. Baabgai beamed toothlessly at them. Khasar looked away as the crippled man’s throat was cut. It was a kindness not to leave him alive for dogs and rats.
