Ballista thought about his family. He did not want to die here in the dark on this lonely plateau swept by a cold south wind. He wanted to see his family again: Julia's dark eyes, her strangely self-controlled smile; the line of Isangrim's cheekbone, his blue eyes, the perfection of his mouth; Dernhelm's round baby face beaming with triumph as he stood unaided for a few seconds before thumping down on his bottom again.
'There is something out there, to our right – troops, I think.' Maximus' words brought Ballista back. He listened. The scrunch of gravel under the horses' hooves. The rattle of equipment. The breathing of men and animals. He could hear nothing beyond his immediate environment.
'There,' whispered Maximus. Ballista pulled Pale Horse out of the line. He took off his helmet, cupped a hand to his ear and turned his head slowly, scanning through 180 degrees to the right. Still nothing. Then, from far away, he heard the call of an owl. Many cultures considered it a bad omen. Ballista could not see why. He had always found it a homely, comforting sound. He listened for the reply of another owl. It never came.
A clink of metal on rock. The Hibernian was right. From out of sight in the darkness, not far behind where they rode, came the sounds of armed men. Ballista strained to hear. Was it the missing Roman cavalry? Was it the Sassanids?
Just then came a confused series of shouts from the praetorians. 'Enemy to the right!' 'Halt!' 'Form to the right!' 'Javelins ready!' Shields slammed together. Weapons rattled. The sounds seemed to echo back from the night. The outline of a close-packed body of troops loomed out of the dark.
'Halt! Hold the line!' Then, a nervous praetorian centurion yelled the command for his men to throw. The command was repeated up and down the line. In no great order, each century acting on its own, the front rank ran three, four paces and hurled their weapons. They flew into blackness. Men screamed out there. Shouts echoed back.
For a few heartbeats, nothing. Then the whistle of incoming missiles. Heavy javelins sliced down among the praetorians. They thumped into shields, clanged off helmets and armour. Now, men close by screamed.
Ballista's small party was in no immediate danger. The incoming missiles were falling to their rear, beyond the packhorses. Asking Turpio to hold the men where they were, and telling Maximus to follow, Ballista wheeled Pale Horse off to the left. They cantered down behind the imperial baggage and the backs of the praetorians. No incoming arrows, just javelins. No sound of horses, just foot soldiers. Not the missing cavalry? Not Sassanids? A javelin overshot the praetorians. It skidded along in front of Pale Horse. Even in the gloom, Ballista knew it was not an eastern weapon.
'Cease shooting! Form testudo by centuries!' Ballista was on horseback. He had a voice accustomed to issuing commands. The praetorians hurried to obey this unknown officer who had appeared behind them. The ragged line resolved itself into small clumps of men, roofed over with shields fitted together like tiles. Javelins continued to scythe in out of the darkness. Maximus swore as one flew far too close.
'Cease shooting!' Ballista bellowed at the outline in the dark. 'Pietas!' – he roared the night's watchword. One or two more javelins fell. Then they stopped.
Nothing moved… but there was a chest constricting tension in the stillness. Ballista moved Pale Horse to one of the gaps between the praetorian centuries. The darkness stretched in front of him. A rocky ground. An indistinct outline at the limit of his vision. He walked Pale Horse out into no-man's land. Suddenly, it was very quiet, just a few men moaning in the distance and the sound of the gelding's hooves on the hard ground. Ballista felt very exposed. 'Pietas!' he called again.
'Pax Deorum!' came the correct answer. Ballista exhaled with relief, but he kept Pale Horse to a very slow walk. Men on both sides were jumpy.
'Identify youself.'
An officer on foot detached himself from the mass and walked to meet Ballista. 'Marcus Accius, tribune commanding the third cohort of Celts. And you?'
'Marcus Clodius Ballista. The men behind me are the Praetorian Guard.'
There were shouts and catcalls from the dark. The praetorians were detested as pampered parade-ground soldiers by both auxiliaries and legionaries. 'Silence!' Accius roared over his shoulder.
Ballista swung down from the saddle. Accius stepped up angrily. 'Why did those praetorians start shooting at us? I have men down. It is their fault.'
'They are nervous' – Ballista spoke calmly – 'but you are out of position. The blame is shared. Now gather your wounded and fall in behind the praetorians. We still have a long way to go tonight.'

The day came almost unannounced to the tired men of the army. One moment, all was black, the next there was a broad band of brilliant blue on the horizon. Above it, the dark of the night, now tinged purple, stretched away up over their heads and off to the west. The sun would be up soon.
The army was halted. Ballista had taken the weight off Pale Horse's back. He was giving the gelding a drink and a small tub of mash. Maximus touched his arm and pointed. Camillus was riding back down towards the imperial party. Handing his mount over, Ballista walked up alongside the Equites Singulares until he was in earshot.
'Dominus.' Camillus sketched a salute to Valerian. The tribune of VI Gallicana looked exhausted. 'Anamu has gone.'
'Most likely,' Quietus said quickly, 'he is merely scouting ahead.'
'No, he has gone,' Camillus snapped.
'How can -'
'Dominus,' the Praetorian Prefect interrupted, 'we have a more pressing matter.' Successianus pointed to the east.
The sun was rising over the crest of the hill. The skyline seemed to waver, to be moving. Speechless, the Romans watched in horror. The sun rose higher, silhouetting the solid black mass of Sassanid cavalry. The horsemen filled the horizon. Golden rays glinted on their spear points and helmets. Bright colours flashed from the banners above their heads.
'Gods below,' muttered Valerian.
Everyone looked around. The Roman army was in a broad upland valley, somewhere between the city of Edessa and the Euphrates river. No one knew where. After the chaos of the night march, they were totally lost. The floor of the valley was bare except for patches of thorny scrub. It was ringed with hills.
A single trumpet rang out from the eastern hill. Its clear notes echoed back and forth in the still, early-morning air. Then, with a sickening inevitability, it was answered. Once, twice, three times. From the south, the west, the north, trumpets rang out. On all the surrounding hills appeared rank after rank of the enemy. A murmur of dismay ran through the Roman army.
'What have we done for the gods to desert us?' Valerian sounded old, defeated.
'Dominus' – Quietus' voice was wheedling – 'you must parley with them.'
The heavy silver head of the emperor continued to regard the easterners. His face became set. He squared his shoulders. 'An imperator under arms does not parley. Successianus, have the light infantry flank our column. Comites, we march north.'
Ballista ran back to his men. As he checked Pale Horse's girths, a thin screen of Mesopotamian archers got into position on either side. He mounted up and they moved off.
The tired men of the beleaguered field army trudged on. They did not have long to wait. The terrible, familiar drums thundered, resounding around the valley. The easterners gave voice, calling on Mazda to grant them victory. Thousands of Sassanid horse bowmen raced down the slopes. Their mounts ate up the ground. Quickly, they were on the Romans.
The air was filled with the ghastly sound of thousands of razor-sharp arrowheads. Ballista saw them fall like hail among the Equites Singulares in front. Horses reared and plunged. Men toppled from saddles. Pale Horse shied as a missile whipped past his nose. Ballista calmed him and concentrated on using his shield to keep the points away from his beloved animal. To the northerner's right, Maximus, holding his shield in his right hand, was doing the same with his mount.
