'Jebe, I want your tumans to cross the Sajo river without delay,' he said.

The general frowned. 'If I were the Hungarian king, I'd hit us now, with the river preventing us from manoeuvres. He must know there is only one bridge.'

Tsubodai turned in the saddle, staring out over the thread of the river, just a few miles away. Already, Chulgetei's tuman was being compressed on the banks. They could not stay there, up against the deep river.

'This king has driven us in triumph now for five days. His officers will be congratulating themselves and him. As far as he knows, we will run right to the mountains and be pushed back over them again. I think he will let us go, but if he does not, I will still have twenty thousand ready to show him his error. Go quickly.'

'Your will, orlok,' Jebe said. He dipped his head and rode clear to pass on the order to his tuman.

Batu cleared his throat, suddenly uncomfortable in Tsubodai's presence.

'Is it time to reveal your plans to lowly generals, orlok?' he said. He smiled as he spoke, to take out the sting.

Tsubodai glanced at him. 'The river is the key. We have run and run. They will not expect an attack, not now. They will press us when they see we are beginning to cross, but we will hold them with arrows. By nightfall, I want them on this side and our tumans on the other. It is no more than this king would expect from such easily driven enemies.'

Tsubodai smiled to himself. 'Once we are across the Sajo, I will need the last minghaan to hold that bridge. It is the only weak spot in my preparations, Batu. If that thousand is quickly overwhelmed, they will be on us and the choke-point of the river bridge will have been wasted.'

Batu thought about the bridge, which he had seen on the first crossing, when the tumans came trotting towards Buda and Pest. It was a main road of stone, wide enough for a dozen horses to ride abreast. He could hold it for days against knights, but the Magyar archers would simply use the banks to send shafts in tens of thousands. Even with shields, whoever stood on that bridge would fall eventually. He sighed to himself.

'Is that your task for me, orlok? Another suicidal stand that I should not survive? I just want to be sure I understand your orders.'

To his surprise, Tsubodai chuckled. 'No, not you. I need you tomorrow before dawn. I will leave it up to you whom you send for the task. They cannot retreat under attack, Batu. Be sure they understand that. The Hungarian king must believe we intend to run clear, that we cannot face his host in the field. Holding that bridge will convince him.'

Batu tried to hide his relief as he nodded. In the distance, Jebe's tuman was already on the move, riding as fast as they could through the narrow structure that spanned the river. A seasoned officer, Jebe allowed no delays and Batu could see a growing stain of men and horses on the other side. He heard trumpets behind him and bit his lip as the Hungarian Magyars continued to close the distance.

'This will be bloody, Tsubodai,' he said quietly.

The orlok looked at him, judging his worth with cold eyes.

'We will pay them back for our losses. You have my word. Now go and choose your men. Make sure they have torches to light the bridge at sunset. I don't want any mistakes, Batu. We have a busy night ahead.' Temuge paced the corridor outside the healer's rooms. He was pale at the muffled cries he heard, but he could not go back in. The first cut into Khasar's shoulder had released a white liquid that stank so terribly it had been all he could do to keep from vomiting. Khasar had remained silent then, but he had shuddered as the knife sliced deeper into his back, gouging him. The black paste was still thick on his tongue and Temuge thought his brother was hallucinating when he began to call for Genghis. Temuge had left at that point, with his sleeve pressed over his mouth and nose.

The sunlight had darkened in the corridor as he paced, though the city was never quiet now, not even in the palace rooms. Servants trotted past in groups, bearing anything from food to building supplies. Temuge had to stand back when one group came with a huge beam of oak, for what purpose he did not know. His nephew's woman, Sorhatani, had begun preparations for siege almost on the day Ogedai had fallen. Temuge sneered at the thought, wishing for a moment that Genghis could return to slap some sense back into her. The city could not be held, any fool could see that. The best they could hope for was to send an emissary to Chagatai to begin negotiations. The only living son of Genghis was not so powerful that words were useless, Temuge told himself. He had volunteered to begin negotiations, but Sorhatani had only smiled and thanked him for his suggestion before he was dismissed. Temuge seethed afresh at the thought. At the very moment when the nation needed his expertise, he had to deal with a woman who understood nothing. He resumed his pacing, wincing as Khasar cried out, worse than before.

The city needed a strong regent, not Ogedai's widow, who was still so stunned with grief that she looked to Sorhatani for guidance. Temuge thought again of forcing the issue. How many times had he come close to ruling the nation? The spirits had been against him before, but now it felt as if the bones had been thrown into the air. The city was terrified, he could feel it. Surely this was a time when a strong man, a brother to Genghis himself, could seize the reins? He cursed under his breath at the memory of the senior officer, Alkhun. Temuge had tried to sound him out, to gauge his feelings about the two women running Karakorum. The man had known his purpose, Temuge was almost sure. Alkhun had shaken his head. Before Temuge could do more than broach the subject gently, the man had dismissed himself with extraordinary abruptness, almost rudeness. Temuge had been left in a corridor, staring after him.

His thoughts were interrupted as the healer came out, wiping blood and the white filth from his hands. Temuge looked up, but the Chin man shook his head in silence.

'I am sorry. The growths were too deep and there were too many. The general would not have lived much longer. He lost a great deal of blood. I could not hold him here.'

Temuge clenched his fists, suddenly angry. 'What? What are you saying?' he demanded. 'He's dead?'

The healer looked at him sadly. 'He knew there were many risks, my lord. I am sorry.'

Temuge shoved past him and went into the room, almost gagging at the stench of sickness there. He jammed his sleeve into his mouth once again as he saw Khasar staring up at the ceiling, his eyes glassy. The exposed chest was a mass of scars, white rope lines of a thousand battles, reaching down to his arms which were thick with them, so that it barely looked like flesh. He saw again how thin Khasar had become, the bones showing clearly under tight skin. It was a relief that the healer had laid him face up. Temuge had no wish to see those purple wounds again, not while the odour filled his lungs. He gagged as he approached his brother's body, but he managed to reach out and close the eyes, pressing hard so that they remained shut.

'Who will look after me now?' Temuge muttered. 'I am the last of us, brother. What did I ever do to deserve such a fate?' To his astonishment, he began to weep, the tears feeling hot against his cheeks.

'Get up, you fool,' he said to the body. 'Just get up and tell me I am weak and pitiful for weeping. Get up, please.' He sensed the healer's presence at the door and spun round.

'My lord, do you want…' the man began.

'Get out!' Temuge roared. 'This is not your business!'

The healer vanished from the door, closing it softly behind him.

Temuge turned back to the figure lying on the bed. Somehow the smell had ceased to bother him.

'I am the last of us, Khasar. Bekter and Temujin and Kachiun, Temulun and now you. You are all gone now. I have no one left.' The realisation brought fresh tears and he slumped into a seat. 'I am alone in a city that waits to be destroyed,' he whispered.
