Pozhar threw her head up, sensing Vasya’s sudden urgency; she said, “I must go to him,” just as the Bear hurled himself snarling in her way.

“Are you a fool?” he demanded. “Do you think there is no man, out of all of them, with the wit to see you or that golden horse? Can you rely on it, when all eyes will be fixed on your brother? Can you be sure that no Tatar will raise no cry of treachery?” And seeing Vasya staring at him, stone-faced, frozen, he added, “The monk will not thank you. That Tatar tortured him; he is doing it for Dmitrii, for his country, for himself. It is his glory, not yours.”

She turned round, indecisive, agonized.

They were all drawn up, the armies of Rus’ and the armies of Mamai, and shivering in the dawn mist, their mail cold and heavy. Among them were the powers that no one could see. The vodianoy of the Don, waiting to drown the unwary. The leshy of the woods, concealing men in his branches. The grinning king of chaos. The lesser chyerti of wood and water.

And unseen, powerful, aloof, the king of winter. He was in the clouds in the north, the hard, chill wind, the occasional snowflake on her cheek. But he would not come down and stand among them. He would not fight Dmitrii’s war. She had seen the terrible knowledge in his eyes: My task is with the dead.

I could be far from here, Vasya thought, seeing her hands tremble. I could be far away, beside the lake, or at Lesnaya Zemlya, or in a clean forest with no name.

Instead I am here. Oh Sasha, Sasha, what have you done?

* * *

ALONE, BROTHER ALEKSANDR RODE onto the swampy field of Kulikovo, rode between the spears of Dmitrii’s vanguard and out into the open space between the two armies. There was no sound but Tuman’s soft snorting breath, and the suck of her hooves in the sodden earth.

   A man on a tall red horse rode out to meet him. More than a hundred thousand men on that field, and still it was quiet enough for Sasha to hear the wind rising, sighing as though in sorrow, blowing down the last of the leaves.

“A fair morning,” said Chelubey, sitting easily on his stocky Tatar horse.

“I am going to kill you,” said Sasha.

“I think not,” said Chelubey. “In fact I am sure not. Poor holy man, with the scars on your back and your torn hand.”

“You cheapen this,” said Sasha.

Chelubey’s face was grim now. “What is this to you? A game? A spiritual quest? It is only men against men, and whichever side prevails, there will be women wailing and blood on the earth.”

Without another word, he wheeled his horse around and cantered a few paces away, turned and stood waiting.

Sasha did likewise. Still, all was silent. Strange, in all that gray morning, with men in the ten thousands waiting. Once more he thought he glimpsed a single horse glowing gold in the last of the mist, a slender rider on her back; at her side was a hulking black shadow. He breathed a silent prayer.

Then Sasha raised his spear and shouted, and at his back came a roar from sixty thousand throats. When had the Rus’ last come together? Not since the days of the grand princes of Kiev. But Dmitrii Ivanovich had drawn them together, there on the cold bank of the river Don.

Chelubey shouted in turn, his face bright with joy; the sound of all his people shouting at his back. Tuman stood steady beneath her rider, and at Sasha’s touch she shot forward. Chelubey kicked his powerful chestnut and then they were racing across the marshy ground, mud and water flying from beneath their horses’ hooves.

* * *

VASYA WATCHED THEM GALLOP, her heartbeat strangling-fast in her throat. Their horses threw great arcs of mud with each stride. Chelubey’s spear dipped at the last moment, to catch her brother in the breastbone. Sasha’s shield deflected the full force of the blow; his own spear rattled along the scale on Chelubey’s shoulder, and broke.

   Vasya put a hand to her mouth. Sasha dropped his broken spear-haft and drew his sword just as Chelubey wheeled his chestnut, icy calm. The Tatar still had both his spear and his shield; he guided his mare with his knees. Sasha’s sword had less than half his reach.

A second pass. This time, at the last instant, Sasha touched Tuman’s side. The quick-footed mare feinted left, and Sasha’s sword came down on Chelubey’s spear-haft. Now they were both armed only with swords, and wheeling their horses once more.

Now it was close-work, striking, feinting, drawing back. Even from a distance, the ringing of their swords came clearly to her ears.

The Bear smiled with pure unfeigned joy, watching.

Chelubey’s chestnut mare was a little quicker than Tuman. Sasha was a little stronger than Chelubey. By now, both men had mud on their faces, dirt and blood on the necks of their horses, and they grunted each time their heavy swords struck.

Vasya’s heart was in her mouth, but she couldn’t help him. Nor would she. This was his moment; his teeth were bared, and in his face was glory. Her palms were bloodied with the impress of her nails.

Fine snow stung her face. Vasya could hear the voices of chyerti rising too, and also the voices of Russians, calling encouragement to her brother.

Sasha parried another thrust and scored a strike along Chelubey’s ribs, tearing away the chain mail. Chelubey blocked a second blow with his sword, and then the two men had their swords pressed hilt to hilt. Sasha did not falter; he heaved with all his strength and threw Chelubey out of the saddle.

The Bear roared when the Tatar fell, and all the men on both sides screamed out. Chelubey and Sasha were grappling in the dirt, swords gone, only their hands and fists now. Then Sasha’s hand, groping, found his dagger.

He buried it to the hilt in Chelubey’s throat.

All around the Russians shouted victory; all of Vasya’s chyerti cried out likewise. Sasha had won.

   Vasya let out a shaken breath.

The Bear sighed, as though in the most profound satisfaction.

Sasha stood straight, his bloody sword in his hand. He kissed it and lifted it to heaven, saluting God and Dmitrii Ivanovich.

Vasya thought she heard a single voice, Dmitrii’s voice, calling to his men, “God is on our side! Victory is sure! Ride now! Ride!” And then the Russians were charging, all of them, massed, screaming the name of the Grand Prince of Moscow, and of Aleksandr Peresvet.

Sasha turned, straight-backed, as though to call to his horse and join the charge. But he didn’t call.

The Bear turned to look at Vasya, his eyes eager and intent. And then Vasya saw it, the great rent in Sasha’s leather armor, where a sword-thrust had found its mark, unseen in the melee.

“No!”

Her brother turned his head as though he could hear her. Tuman had come back to him, and he put a hand to the pommel of her saddle, as though to vault to her back.
