I have already changed the future, thought Ivan. There will be different folktales now, to take into account in my dissertation. The lists and charts will be altered.

And then he wondered: What if the folktales I studied already included what we added here? What if the Ivan of the Russian folktales—Ivan, who was as common as Jack was in the English tales—was really Ivan Smetski, a Jewish boy from Kiev?

Now that he thought about it, he could see that he was right. For he had proof. He knew the origin of the tales of Baba Yaga's house that stood up on chicken legs and ran from place to place at her command. In all his years of study, he had never seen a single speculation from a folklorist or literary historian that the original of the witch's walking hut might be a hijacked 747. Yet there were the stories all along.

So everything that is happening now had already happened before I was born, thought Ivan. The hijacked jet. The coming of a common peasant named Ivan, untrained in battle but blessed with magical charms and gifts from his mother. The man who marries the princess, but then finds himself in mortal danger. He had read these tales before, never guessing that he would live through the originals.

What, then, of the tales that Sergei had written down at his behest? Those were the pre-Ivan tales, the stories from the time before Baba Yaga got her walking house. The lore of the folk before being corrupted by his backward passage through the centuries.

But what did the stories say the outcome would be? Ivan won in most of the tales Ivan knew, but that didn't guarantee a victory in this case, for not one of the tales told of Ivan commanding a group of grenade-throwing boys in the midst of battle. Did the silence mean that they would lose today, their exploits forgotten because everyone who witnessed them had died? Then only the women of Taina would be left, to tell the tales that they already knew before the battle's start.

No, no, he could not reach any conclusion from the silence. Besides, there were more Ivan stories that were nothing like the things that he'd already done. Couldn't he live to have more adventures? Only if they had a victory today, for it was certain that in defeat there would be no escape for him.

Of course, those other Ivan stories might be more embellishments, told about a legendary figure who was dead.

Russian fairy tales were the only ones he'd read that were so grim, even the princess sometimes died.

Why couldn't I have been born a nice Protestant boy from Omaha or Sacramento? Why couldn't Katerina have been the unattainable girl that somehow agreed to let me take her to the prom? Why couldn't I have been the track star with the letters on my jacket, instead of making bombs and Molotov cocktails, and sending my wife into the air to face a dire enemy alone?

Lost in thoughts like these, Ivan let the conversation drift around him until someone called him back. Misunderstanding his inattention, Sergei whispered to him, "Don't be afraid. I believe God has chosen you for a great work."

To which Ivan, just as quietly, replied, "He chose his own son, too, and look how that turned out."

At last the councils and the conversations ended. Ivan and Katerina slept then, their first time together on the straw mattress of her bed in King Matfei's house. They did not make love, but only held each other, whispering their happiness over the time they had together, plus a few hopeful comments about the baby that yes, indeed, Katerina carried in her womb.

It was a fine morning for a war. They set out with songs and tears—the songs of men putting on a show of bravado, the tears of women mourning in advance while protesting through their sobs that they knew God would protect him—husband, son, brother, father. It was a scene that had played out ten thousand times already, and would play again ten thousand more.

They marched that day and slept that night, consuming half the food they carried with them. What more was needed? If they won. they would have Baba Yaga's lands to pillage; if they lost, there would be no need for food at all. The second half of their supply was only to feed them if by some chance the battle lasted until a second day.

Somewhere behind them, on a high hill, Katerina would be launched at dawn, the few men she had with her watching her out of sight, then rushing to bring their report. Ivan tried not to think of that, but rather to concentrate on the task at hand. A dozen match boys, including Sergei, who—though a good thrower—could not possibly dart in and out among the fighting men. Four times as many who carried a half-dozen grenades and cocktails each. The grenades, they knew, were to throw once at the start, to frighten the peasants of Baba Yaga's army, and then to hold in reserve, for they were too dangerous to use among the soldiers, where the shrapnel could kill a man of Taina as easily as his foe. For the close-in work, the cocktails would do the job, and when a boy had run out of his supply, he was to flee back behind the line of battle, to wait. If the worst came, and they lost the day, then these boys were to be the rear guard, using their grenades to cover a retreat, delaying the enemy long enough that there might be hope for some, at least, to get away.

Get away, yes, but not back to Taina, for that would be Baba Yaga's land, and the women would be given to her followers. Any man found there after a defeat would be killed or enslaved and sold far away. To Constantinople, perhaps, where they might live as Christians despite their slavery, to weep the remainder of their days, remembering their wives and daughters, now belonging to other, crueler men; remembering their sons and brothers who were lucky enough to die in battle rather than living out their lives in such despair.

None of this was said aloud. But all of them knew what lay ahead, if the day was lost. But what made it possible for them to fight was the knowledge that if they did not struggle against Baba Yaga, the outcome would be the same, except that all the men would be sold as slaves, and without even the comfort of knowing that they fought for their families, their God, and their king.

The battle would be fought where it had to be fought—the selfsame meadow that was large enough to land a plane. Baba Yaga's army hovered in the shelter of the trees on the eastern side of the meadow, with the morning sun at their backs. King Matfei emerged from the wood and arrayed his army almost exactly as Baba Yaga's men were organized—peasants to the left and right, the druzhina in the middle, to guard the king and lead the push into battle.

The same, but with two important differences. Baba Yaga's army was larger, at least double the size of King Matfei's. And as the armies moved forward, ready to collide, young boys darted out from among the men of Taina, carrying something burning in their hands. Were they such fools as to think that they could set such a green meadow on fire?

Then they threw their canisters, some of which burst open in midair with terrifying noise, right above the heads of the peasants. Tiny shards of metal were flung out at such speeds that they could cut open a man's face or throat as he raised his head to see what this strange weaponry could be. Many fell; the rest, seeing the hideous wounds on their comrades and deafened by the booming noise, cried out in panic and ran away.

In three minutes of chaos, Baba Yaga's army became nothing but her druzhina and a handful of peasants, who now bunched up as close to the knights as they could manage. In moments they were underfoot, the druzhinniks screaming at them to get out of the way, and finally lashing out at their own peasant soldiers to get clear of them.

Again the boys ran forward with fire in their hands, but this time Baba Yaga's knights only laughed, for they had seen how the shrapnel from the grenades did not penetrate their helms and mail and heavy leather garments. These loud noises might scare away peasants, but there were still three knights of Baba Yaga for every knight of Taina.
