'If we win today the noble emperors Valerian and Gallienus will declare this day a day of thanksgiving, a sacred day to be celebrated as long as the eternal city of Rome stands. The noble emperors will open the sacred imperial treasury. They will shower us in gold.' The soldiers laughed as one with Ballista. The elder emperor was not renowned for being open-handed. Ballista waited a moment, then, altering the tone of his voice, went on.
'Today is the last day of our suffering. If we win today we have won our safety with our own swords. If we win today we will have earned our fame, which will be remembered down the centuries. We will be remembered with the men who beat Hannibal at Zama, the men who beat the barbarian hordes of the Cimbri and Teutones on the plains of northern Italy, the men who beat the Asiatic multitudes of Mithridates the Great, humbled his oriental pride, and drove him to exile and a squalid suicide. If we win today we will be remembered from this day to the ending of the world.'
All the men cheered. The din of swords beaten on shields was deafening. The chant rang out: 'Ball-is-ta, Ball- is-ta.' It was picked up and, like a great wave, it rolled down the wall walks and towers of the embattled town.
When they left the tower it was the time of morning that the light of torches first turns a pale yellow then fades to nothing. They walked south the length of the wall. At every tower Ballista made a version of his speech. Always the listeners cheered; sometimes they chanted 'Ball-is-ta, Ball-is-ta'; sometimes they tipped their heads back and howled like wolves. By the time they had walked north again and taken their accustomed places high on the Palmyrene Gate the sun was hot on their backs.
'Dominus.' Two troopers of Cohors XX stood to attention. Between them stood a man in Persian dress. 'Marcus Antoninus Danymus and Marcus Antoninus Themarsas of the turma of Antiochus, Dominus. This here is a deserter. Came up to the north wall last night. Says his name is Khur. Says he can tell you all you want to know about the Persian plan of attack.'
At the sound of his name the Persian showed his teeth like a dog expecting a beating. The man's colourful clothes were grimed in dust. His loose long-sleeved tunic was unbelted. The belt must have been removed when he was searched and disarmed. Under the dirt his face was pale.
Ballista gestured him forward. The Persian came close, then prostrated himself. He bowed his forehead to the floor then got up to his knees, his arms out in supplication.
Demetrius watched the man with distaste as Ballista spoke to him in Persian. Before he replied the Sassanid prostrated himself again, covering his hands with his long sleeves. It was disgusting how these orientals abased themselves.
The man got to his knees again and lunged up at Ballista. The knife shone in the Persian's hand as he thrust it to stab below the northerner's cuirass. Quicker than Demetrius could follow, Ballista stepped forward and inside the blow. Seizing the Persian's arm with both hands, Ballista brought his knee up. There was a loud crack as the arm broke. The man screamed. The trooper called Danymus leapt forward and drove his sword between the shoulder blades of the Persian. The easterner fell forward. In a few seconds he had choked his life out.
'That was unnecessary, soldier,' Ballista said.
'Sorry, Dominus. thought…' Danymus's voice trailed away.
'I take it he was searched?'
'Yes, Dominus.'
'Who by?'
'I do not know, Dominus.'
'Not by you?'
'No, Dominus.' Danymus dropped his eyes to where the blade of his sword was dripping blood on the floor. He was sweating heavily. His crestfallen manner was at odds with the jaunty ornaments on his military belt: a sunburst, a flower, a fish, a man carrying a lamb and a swastika. It struck Demetrius that the Persian's killer was the only one present with a drawn blade.
'Very well. Take the corpse away.'
Danymus sheathed his weapon and the two troopers, taking a leg each, dragged the Persian towards the stairs. The man's face scraped along the floor. He left a trail of blood.
'Pick that fucking corpse up. Someone could hurt themselves if they slipped in that blood,' Castricius roared.
Ballista and Maximus looked questioningly at one another. If he had been disarmed when he deserted, someone must have given the Persian the knife. There was no time to investigate that now. They could search for the culprit tomorrow, if they were still alive. Almost imperceptibly, Ballista shrugged and then turned to look up and down the wall.
Unable to take in the sudden eruption of extreme violence followed by the equally abrupt return to something like normality, Demetrius watched as his kyrios took off his helmet. As Ballista handed it over, Demetrius realized that his own hands were shaking. The big northerner smiled a tight smile and said that he ought to show the boys that he was still alive. Demetrius became aware of the oppressive silence on the battlements, the sort of silence that precedes a thunderstorm. He watched Ballista climb up on to the frame of the nearest artillery piece and raise his arms above his head. Turning slowly so that all could see him, he waved. The southerly wind caught his sweat-flattened hair. The polished cuirass gleamed in the sunshine. There was a strange noise like a thousand men exhaling at once. Nearby a voice shouted, 'Flavius, Flavius.' Along the wall walk soldiers laughed and took up the chant: 'Flavius, Flavius,' 'Blondie, Blondie.'
'So that is what they really call me,' Ballista said as he climbed down.
'Among other things,' said Maximus.
When Demetrius tried to hand back the helmet, Ballista asked him to put it with the other things until it was needed. The young Greek went and placed the helmet on the carefully folded wolfskin next to the kyrios's shield which, after some consideration, the young Greek had earlier put out of harm's way in the corner of the tower.
From the front parapet, Ballista inspected the defences. The men waited quietly. Above their heads, the banners snapped in the breeze. Two towers to the south, where Turpio was stationed, flew the green vexillum of Cohors XX, the unit's name picked out in gold, the image of its patron deity, a proud Palmyrene warrior god, shifting. On the southernmost tower was larhai's battle standard, the red scorpion on a white background. Haddudad would be standing there. Ballista wondered if Iarhai himself would be present. Away two towers to the north was the red vexillum of the detachment of Legio IIII, on it the personifications of victory in blue, the eagle, the lion and the lettering all gold. The young patrician Acilius Glabrio would have taken his stand under that. Beyond that flew the yellow-on-blue four-petal flower of Anamu. Beyond that again, near the north-west corner of the defences, was the banner of Ogelos, a golden image of the goddess Artemis on a purple background. And, in the centre, above the main gate, the white draco of the Dux Ripae hissed and snapped. Here and there along the wall the air shimmered where the fires were heating the sand to a crackling, spitting heat.
The city of Arete was as ready as it could be to face this ultimate test. This wall had become the final frontier of the imperium, where West met East, where Romanitas, even humanitas itself faced Barbaricum. The irony that four of the six standards that floated over the wall of Arete could in no real sense be described as Roman was not lost on Ballista.
He looked out across the blasted plain at the Sassanid horde. It was the fourth hour of daylight. The easterners had taken a long time getting arrayed for battle. Was this reluctance? Had it proved hard for Shapur, his client kings and nobles to have their men stand once again in the dreadful battle line? Or was it calculation, the desire for everything to be right? Were they merely waiting for the sun to be pulled clear of the eastern horizon, out of their eyes as they gazed on the stark, lonely wall of Arete?
The Sassanids were ready now, a dark line which stretched across the plain. The trumpets and drums fell silent. Thousand upon thousand warriors waited in silence. The wind kicked up dust devils out on the plain. Then the drums thundered, the trumpets shrilled. The sun struck the golden ball which topped the great battle standard of the house of Sasan as it was carried across the front of the army. The Drafsh-i-Kavyan glinted, yellow, red and violet. Thin at first then filling, the chant of 'Mazda, Mazda,' came across the plain. The chant faltered and died, then a new one began, this one stronger: 'Shapur, Shapur.' His white horse kicking up the dust, the purple and white streamers flowing behind him, the King of Kings rode to the front of his army. He dismounted, climbed on to the high raised dais, settled himself on his golden throne and signalled that the battle should begin.
The trumpets struck a different note. The drums hit a different rhythm. A slight hesitation, and the Sassanid
