Constantine climbed onto a pile of rubble, looking out in the twilight over the heads of his men. “Do not fear the evil Turks!” His booming voice was punctuated by a distant impact. “Our superior armor will protect us. Our superior fighting will protect us. Our God will protect us! Their evil sultan started the war by breaking a treaty. He built a fortress on the Bosporus, on our land, all while pretending at peace. He looked on us with envy, lusting after the city of Constantine the Great, your homeland, the true homeland of all Christians and the protection of all Greeks! He has seen the glory of our God and wants it for himself. Will we let him take our city?”

The men shouted no angrily.

“Will we let the call to prayer corrupt the air good Christians have breathed for more than a thousand years?”

Another roar, even louder.

“Will we let them rape our women, murder our children and elders, and profane the sacred temples of God by turning them into stables for their horses?”

This time the roar of anger was accompanied by the slamming of spear butts into the ground and the pounding of fists on shields. Radu could not point out that it had been a Christian crusade two hundred years before that had been guilty of all the above.

Constantine continued on. “Today is your day of triumph. If you shed even one drop of blood, you will prepare for yourself a martyr’s crown and immortal glory!” He raised a fist in the air. “With God’s help we will gain the victory! We will slaughter the infidels! We will bear the standard of Christ and earn our eternal rewards!”

The sound of the cheering and screaming was almost enough to drown out the bombardment. Constantine held his arms in the air, then lowered them and turned. His face was haggard and drawn, losing light as quickly as the day turned to night around them. “We lock the gates back into the city,” he said quietly to Giustiniani. “We stand or fall where we are. No one gets out. If the wall falls, we all die together.”

Giustiniani nodded grimly.

Radu watched the two men with a disconnected sense of farewell. In his time here, he had seen them be truly great, holding together a city against impossible odds. And he had seen them commit atrocities while doing it. He respected them, and he hated them, and he knew the world would be lesser for their deaths.

If they died.

He both hoped for and dreaded that outcome, impossible to reconcile, just like everything else in this accursed city. He took a place on the wall next to Giustiniani. Although it was night, the Ottomans had lit so many fires the light bounced off the low clouds, creating an ominous orange haze everywhere. The defenders could not repair the walls, because there was no cover of darkness.

From his vantage point Radu could see the mustering area for the Ottoman troops. Somewhere nearby, Mehmed waited to find out whether his grand design would succeed or fail, whether he would fill the prophecies of generations. Maybe if Radu were out there with Mehmed, this would have all been exciting. It made him ill to think of it, to imagine who he could have been. How easily he could have wanted the end of this city and everyone in it.

It also filled him with longing, knowing it could have been simple. But he released that thought to the night, too, along with everything else. He would die on the wall tonight, between his brothers and his enemies, because he could no longer distinguish between the two. They had finally come to the end. Whichever side won, neither would triumph.

A stone cannonball slammed into the wall beneath Radu and Giustiniani. They fell to their knees, the impact jarring Radu from his toes to his teeth. He shook his head, trying to clear the strange ringing noise in his ears.

No. Not ringing. Screaming. He looked up past the defensive barrels to see a shouting horde rushing toward them. There was no order or sense to the approach. They ran like a swarm of locusts, over each other, pushing and shoving, each trying to get there first.

Those that did were cut down. But it did not matter. The ones behind them climbed over the bodies. When they, too, were killed by arrows, their bodies added to the pile. Radu shot into the melee, watching in disgusted horror as the irregular forces of Mehmed’s army used the corpses—and sometimes the living injured—as steps. They clawed over each other, death itself a tool to crest the wall.

There were so many men that Radu could not help but hit someone with every arrow he fired. It was as effective as shooting at waves of the sea. The men never stopped coming. Giustiniani directed his own forces, anticipating whenever a group of irregulars would breach the wall. “There!” he shouted, pointing toward a stretch not far from Radu. Radu ran toward it, watching as the first few soldiers clawed and tumbled their way on top.

There were not enough men behind Radu. He had gotten there too fast. He hacked and slashed and blocked, but there was no hope. A man screaming in Wallachian barreled into him, tripping him. Radu fell flat on his back, looking up into the face of death. No matter where he went, his childhood followed. And now it would kill him.

Then the man was gone. Except for his torso, which fell across Radu’s feet. Radu blinked away the dust and smoke. All the irregulars who had breached the wall had been cut down by one of their own cannonballs. Radu kicked the man’s body away, laying his head back onto the wall and laughing.

Urbana and her cannons had saved his life after all.

He pushed himself up, rushing to Giustiniani. He was certain that he had been fated to die just then. But he was still here. Which meant he could still accomplish something. This time, if an opportunity presented itself, he would not falter.

Much farther along the wall, Constantine threw a man over the side. He pointed and a spray of Greek fire lit up the night, burning the bodies of the living and the dead against the wall. The Greek fire moved up and down, consuming everything that wasn’t stone. Men ran screaming, the attack’s momentum gone.

“They are retreating!” Giustiniani roared. The men around Radu cheered, some crying and some praying. Between Constantine and Giustiniani, the city still stood a chance. Giustiniani clapped Radu on the shoulder. “You made it! I am glad.” They ducked as a cannonball whistled overhead, falling somewhere in the space between the two walls. “Do you think we have them on the run?”

“They were intended to wear us down. Next he will send Janissaries.” Mehmed would have saved his best men for last. And Radu knew without question that the next wave really would be the last. If numbers could not overwhelm the wall, only the Janissaries stood a chance. And if they could not win … Mehmed was finished. He had nothing left to throw at them.
