He took the bow from his bow case, whipped an arrow on to the bowstring, and loosed at the dozen horsemen charging them. As far as Swan could see, he missed, but his attention was now on the two horsemen behind him.

The sailor got to his feet and went to retrieve the helmet.

The nearest mounted Turk put an arrow into him from fifty feet. The sailor screamed, fell heavily on all fours, and screamed again, shot in the groin.

The two Turks started towards Swan.

Swan picked up a rock. It was all he could think to do.

An arrow whistled over his head.

He jumped, a move his uncles had taught him, leaping hard with both feet. He landed by the helmet, and his right arm went back.

The nearest Turk took a crossbow bolt just above the waist. He collapsed back, then forward, and still didn’t fall from his horse’s back, even though the bolt was sticking halfway out of his back. But he dropped his bow.

The farther man had to rein in to avoid his mate’s horse, and Swan threw, with all his fear and hate behind it, and his rock struck the man’s horse in the head, and the horse shied violently, sidestepping, rearing, and blew out a great breath, utterly spoiling his master’s aim, and that arrow vanished well over Swan, who charged the Turk while the man tried to get control of his horse, his right hand seizing his sword back from his left. A few paces behind Swan, the wounded Turk finally fell from the saddle, and his horse stopped immediately and stood over her fallen man.

The Turk nearest Swan gave up on fighting his mare, dropped his bow, and drew his sword.

Swan made it to his side and pushed his buckler at the man, drawing a heavy cut that rang off the buckler’s steel boss, and Swan’s counter-cut scored, cutting the man’s fingers and his wrist – having hit, Swan cut a reverso up into the man’s chin, and punched it home with a jab like a boxing blow – all in a pair of heartbeats. It was a set piece he’d learned from the maestro in Venice, and it worked beautifully, even when his opponent was four feet higher and cutting down.

He was still admiring his own swordsmanship when his victim’s horse knocked him flat. His backplate took the animal’s kick, and he rolled in the dust and saw the Spaniard loose an arrow.

The other group of Turks had stopped to shoot. It was a natural reaction for an archer, but it cost them time, and the Spaniard loosed shaft after shaft – not accurately, but the Turks were densely enough packed that many of his arrows hit horses, exposed flesh – even a ricochet, or a broken splinter in a horse’s hoof, could change the course of a small fight. And his flow of shafts disconcerted them.

And another carefully aimed crossbow bolt struck, tearing a horseman from his saddle.

Swan got to his knees, the pain in his back ebbing from unbearable to bearable where the horse had kicked him. He retrieved his sword, got to his feet, and stumbled from the pain.

The Turks had begun to return the marine’s arrows, with interest – six for one. But the Spaniard was canny – he loosed and moved, loosed and moved, always headed for the cover of the market plaza and the distant fountain.

Swan saw Giannis at the edge of the market as the Greek man-at-arms leaned out from the cover of an ancient pillar and snapped off another crossbow bolt. It hit a horse.

Swan went from walking to a stumbling, shuffling jog. Two arrows passed close to him, but the Turks were now concentrating all their arrows on the Spaniard, and all that came his way were overshots.

He managed to run.

The bishop lay unmoving. The head of St George lay in the middle of the street, wrapped in his armet.

He couldn’t think of rescuing either of them, right now. Instead, he passed the bishop, got a hand up, and seized the bridle of the horse standing by the corpse of the first man Giannis had killed. Without breaking stride he vaulted into the saddle, gathered the reins, and leaned way out over the horse’s neck.

‘No! Thomas!’ yelled Alessandro at his back.

I got them all into this, Swan thought.

He pointed the head of the Turkish horse at the enemy, pressed his spurless heels into her sides and rolled his weight forward over her neck. She got the message and leaped into a gallop. Swan finally got the reins under his buckler hand and concentrated on holding on with his knees.

He kept his buckler up near his head.

He heard the flat crack as Giannis discharged another bolt.

And then he was on them, although his mare was suddenly sluggish – she slowed from a gallop to a canter, and he couldn’t make her turn. His buckler slammed into an archer’s hands as he raised his bow, and Swan almost lost his seat cutting across his body to get the man – a weak blow that nonetheless mangled his opponent’s bow-arm.

Swan had never actually fought from horseback before.

The second Turk loosed at him from a horse length away, and the arrow went through the outer rim of his buckler, passed up the length of his arm, and cut into his neck. Swan was again forced to cut across his body because his damned horse wouldn’t turn – he missed his cut, but by sheer luck the mare’s stumble and the alignment of his point spitted his opponent on his sword, and the man grabbed the blade in his neck with both hands and ripped it from Swan’s grasp.

At that moment, Swan’s horse, shot by a dozen arrows, subsided to the ground. Swan fell and hit the ground gently enough, but now he lost his buckler too.

He rolled to his feet.

There was dust everywhere, and they couldn’t see him, and he had trouble finding them, even a horse length away. He drew the dagger from his hip, ran three steps and threw himself at a man who was looking the other way in the dust. The dagger went home in the man’s back and Swan dragged him from his saddle, but instead of a clean kill and possession of the man’s horse, Swan found himself pinned under the falling man, his feet still caught in his stirrups, and the horse wheeling around them like the equine rim of a human wheel. Swan let go in disgust and fell backwards, and the horse bolted, the corpse of the dead man jolting obscenely behind.

Swan just sat in the swirling dust. It was as if he was a puppet and his strings had been cut. He couldn’t seem to get to his feet.

But the Turks – the survivors – had given the fight up as a bad job, and ridden free. They’d cantered away north, to the next major intersection almost a stadion away. Even as Swan tried to watch them amid the dust and his own fatigue, he saw the first of their arrows winging towards him.

It missed.

He began to crawl back towards the bishop. Then he realised that his most prized possession – the count’s sword – was lying pinned under a dead Turk. He turned and crawled like a baby to the man’s corpse. His hands were still locked around the blade.

Swan got his feet under him and rose.

Arrows began to sink into the street around him.

He got his hands on the hilt and pulled. He wiped it on the dead man’s kaftan, and sheathed it.

And, out of pure stubbornness, he took the man’s curved dagger and his belt purse. Only then did he lurch into an exhausted run. It was only a hundred paces back to the bishop, but it seemed like an English country mile. Men were shouting – another of the Venetian marines was loosing arrows, and arrows were falling around him. The Spaniard slumped to his knees and then fell to the ground.

The bishop rose to his knees and lifted his pectoral cross. The second marine took a Turkish arrow in his shoulder and fell. The sailor who had carried the head lay unmoving. Even as Swan stumbled up, Alessandro lifted the Spaniard over his shoulder – the man must have been hurt worse than had at first appeared. And Giannis snapped another shot at the now-distant Turks and slung his crossbow.

‘Bishop!’ croaked Swan.
