Demetrius shot the Persian boy a vicious look.
Ballista did not press the matter. He knew that the actual number of Persian dead was unimportant. Another hundred dead, another thousand dead – in itself, it made no odds. Given their overwhelming numerical superiority, it was not the Sassanid bodycount that mattered but their willingness to fight, and Shapur's willingness to commit them to fight. Ballista knew that to save the town of Arete he had to break one or the other. He suspected that the Persians would crack before their King of Kings.
Roman casualties were by comparison negligible. Yet they were higher than Ballista had anticipated, higher than was sustainable. The Sassanid arrow storm had been like nothing the northerner had experienced before. For a time he had thought it would empty the battlements of defenders unaided. If the easterners could be brought to repeat it for three or four days in a row, the defenders would simply run out of men. But Ballista knew that no troops in the world could stand before the walls of Arete day after day and take the casualties the Sassanids had endured.
On the Roman side, the bowmen had suffered most. The six centuries of Cohors XX Palmyrenorum had suffered over 50 per cent casualties. Each century was now down to just fifty effectives. The legionaries of Legio IIII Scythica had escaped more lightly. On average, each of the eight centuries along the western wall had lost ten men, bringing their numbers down now to about sixty each. Ten of Mamurra's artillerymen were absent from the standards. Extraordinarily, as they had been in the eye of the storm, just two of Ballista's bodyguard, the equites singulares, had fallen.
Of the combined Roman casualties of well over 400, about half were dead. They had been buried in the open area to the east of the artillery magazine, which had been designated an emergency cemetery. Ballista was very aware of the dangers of plague and disaffection if the bodies of the defenders were not treated with all due respect. Issues of health and religious sensitivities made the extra effort of burial more than worth while. The rest of the casualties were too badly injured to fight. The majority would eventually die; many of them in agony from blood poisoning. Before that happened, the military medical teams would be very busy. Every trained soldier who could return to the ranks would be very necessary.
When the Sassanid assault failed they had totally quit the field. They had dragged away out of range their mantlets and ballistae, and the luckiest of their wounded. The following day they had stayed in camp, given over to their mourning; high, wild music and wailing, barbaric to western ears. Then, their grief somewhat assuaged, they had turned their hands again to the siege.
The surviving siege tower, the southernmost City Taker, the one which had fallen through the roof of an underground tomb, was hauled back to the Sassanid camp, where it was promptly broken up. The majority of its timbers were reused to construct a very large wheeled shed; what the legionaries called a 'tortoise'. Bagoas was happy to tell everyone what the shed would shelter – no less than the illustrious Khosro-Shapur, the illustrious Fame of Shapur, the mighty ram that had battered down the double walls of the city of Hatra. For fifteen years since that glorious day, Khosro-Shapur had rested, dedicated to god. Now Mazda had put it in the mind of the King of Kings to bring the great ram forth to give anew evidence of its prowess. It would have been transported in pieces, and was now being reassembled to be hung from mighty chains under that shed. Nothing, Bagoas earnestly assured his listeners, nothing, neither gate nor wall, could stand against it.
Thirteen days since the assault, and now it was all going to happen again. Ballista looked out at the squat shape of the tortoise under which sheltered the Khosro-Shapur. He wondered if he had done enough to deny it, to keep it out. Certainly he had done what he could to replace the casualties. Two troopers had been transferred into the equites singulares from the turma of Cohors XX led by Antiochus on the north wall. Likewise, ten legionaries of Legio IIII had joined Mamurra's artillerymen from the century of Lucius Fabius at the Porta Aquaria on the east wall. Ballista had noticed that one of the replacements who appeared on the battlements of the Palmyrene Gate was Castricius, the legionary who had found the body of Scribonius Mucianus. Four hundred men from the numerus of Iarhai had been ordered to take their places on the desert wall. Ballista had made further specifications: 300 of them were to be trained mercenaries and only 100 recently recruited levies; the caravan protector was to lead his men in person; Bathshiba was not to be seen on the battlements. (Ballista put away, as something to consider later, whenever there was time, the strange, new reluctance to fight on the part of Iarhai.) The new arrangements meant that the western wall was nearly as well manned as before the assault. It did, however, mean that the other walls were each defended by only 200 mercenaries backed by a small number of Roman regulars and, in the cases of the east and south, a crowd of levies. Ballista knew that, as the siege went on and casualties mounted, he would be forced to rely more and more on the local levies. It was not a reassuring thought.
Across the plain the Drafsh-i-Kavyan, the battle standard of the house of Sasan, flashed red, yellow, violet in the early morning sun as it moved towards the great battering ram. It was followed by the now so familiar figure on the white horse. As Shapur arrived the magi started the sacrifice. Ballista was relieved to see that, despite their reputation for necromancy, it involved no people. There were no Roman prisoners in sight.
Two of the defenders' ballistae had been knocked out during the assault. One had been repaired, the other replaced from the arsenal. Mamurra had done well. Three of the enemy artillery pieces had been hit; two on the approach, one during the retreat. It could be seen that they had also been replaced. But no more had been constructed. Ballista's rigorous scorched-earth policy was bearing some fruit. There was no timber for miles. If they wanted to build more siege machines the Sassanids would have to fetch the materials from a great distance. Ballista felt reasonably sanguine about artillery; he still had twenty-five pieces on the western wall to the Persians' total of twenty.
Preceded by the Drafsh-i-Kavyan snapping in the wind, Shapur rode across to a raised tribunal, where he took his seat on a throne glinting with precious metals and jewels. Behind the throne loomed the terrifying, wrinkled bulk of his ten elephants. In front were the Immortals commanded by Peroz of the Long Sword and the Jan-avasper, 'those who sacrifice themselves', led by Mariades.
Ballista found it unsurprising that Shapur had not so far tried to use his tame pretender to the Roman throne to undermine the loyalty of the defenders of Arete. Who would follow an ex-town-councillor turned brigand then traitor like Mariades? It was as unlikely as anyone trying to elevate to the purple a barbarian warrior such as Ballista himself.
The battering ram was being cleared for action, camp followers, priests and their paraphernalia herded away. A chant began: 'Khos-ro-Sha-pur, Khos-ro-Sha-pur.' Here was the heart of the matter – the great ram, the Fame of Shapur and its protecting tortoise. From where it had been reassembled, Ballista assumed that it would advance straight down the road to the Palmyrene Gate. He had based his dispositions on this assumption. He hoped that he was right. Everything he could use to frustrate the ram was at the gate. The cowhides and chaff he had requisitioned were piled near by. Would the councillors remember sniggering when their barbarian Dux had announced their requisition? Ballista's three mobile cranes were stationed behind the gate. They were fitted with iron claws, a plentiful supply of enormous rocks to hand. And then there was his new wall. For four days the legionaries had laboured to finish the wall behind the outer gate. It was a pity that the painting of the Tyche of Arete had been obscured by it. The superstitious might read something into it – but Ballista was not superstitious.
Would the King of Kings send the Khosro-Shapur straight down the road into the teeth of the carefully prepared defences? Or would he have been warned by the traitor? Since the failed attack on the granaries, there was one fewer traitor in the town of Arete. But Ballista was sure that there was at least one remaining. It had taken at least
two men to burn the magazine, at least two men to murder Scribonius Mucianus and dispose of his body. Admittedly no traitor had told the Sassanids about the naptha-filled jar buried just before the gate that had trapped the central City Taker. But the northerner felt certain this was proof of a problem of communication rather than evidence that there was no traitor.
Shapur waved his arms, purple and white streamers flying. Trumpets blared and drums thundered. The great tortoise housing the Khosro-Shapur moved forward, as did the mantlets, the ballistae and innumerable hordes of bowmen.
'Do you think he practises that?' Maximus asked.
'What?' Ballista replied.
'Whirling those streamers about. Imagine what a prick he must look practising on his own. Pointless anyway. Not exactly a practical skill.'
'Why do you spend what little time you have when not rattling the bed practising those fancy moves with your gladius?'
Maximus laughed. 'It intimidates my enemies. I have seen grown men cry with terror.'
Ballista looked at his bodyguard without speaking.
'Oh, well, I see what you mean, but sure it is an entirely different thing,' Maximus blustered.
'One cannot help but think that on the whole it is a good thing that I own you, rather than the other way round.'
The great battering ram was coming straight down the road, the mantlets shielding the ballistae and bowmen flung out on either side.
Allfather, here we go again. Almost unconsciously Ballista ran through his pre-battle ritual: slide dagger out, snap it back, slide sword out, snap it back, touch the healing stone on the scabbard.
As the Sassanids came into range past the white-painted humps of rock Ballista nodded to Antigonus, who made the signal, and the artillery began to shoot. This time the northerner had instructed the ballistarii to aim exclusively at the enemy artillery. The Persians pushing the great battering ram would marvel at their luck, an unlooked-for piece of luck which Ballista thought might give Shapur and those around him pause for thought.
Practice was improving the skills of the artillerymen of Arete. By the time the Sassanid line reached the section of white-painted wall, three of their ballistae had been squashed by high-velocity missiles. As the ram, mantlets and bowmen carried on to cross the last 200 paces to the city wall, the Sassanid artillery unlimbered and began to shoot back. Honours were even: two of the defenders' and two of the attackers' ballistae were rendered inoperable. The Dux Ripae was happy enough. This was the only area of the siege where he would win a battle of attrition. Then another thought came to his mind: Disgraceful. Men are dying – my men as well as the enemy – and I am just calculating the numbers of machines destroyed and damaged, the effects on the rate of shooting. Disgraceful. Thank the gods that war can never be reduced to this impersonal machine-against-machine battle alone. If it could, what an inhuman business it would become.
The Sassanid officers had an admirable control over their troops. The archers held their fire until the mantlets were fixed in position just fifty paces from the walls. Not an arrow was loosed until the command. When it came, the sky darkened again. As, with a terrible whistling, the arrow storm hit, Ballista once more marvelled at the almost unbelievable enormity of the thing. The defenders hunkered down behind the battlements and below their shields to weather the storm. Shouts and cries showed that not all had done so unscathed. In the pause before the next wave the bowmen of Arete leapt to their feet and sent back an answering volley.
Crouched behind the parapet, shields held all around him, Ballista knew he had to ignore the arrow storm. It was an irrelevance. Stoic philosophers held that everything that did not touch a man's moral purpose was an irrelevance. For them, death was an irrelevance: fucking fools. Ballista's only purpose was to destroy the great ram, the Khosro-Shapur.
Judging by the tortoise, the ram was about sixty feet long. The head which emerged was capped with a metal sheath, fittingly enough in the shape of a ram's head. It was bound to the shaft with nailed-down strips of metal. The wooden shaft itself looked to be about two feet thick. Like the tortoise it was covered in dampened rawhides.
With suicidal courage, eastern warriors ran ahead to tear away the remains of the burnt siege tower and tip rubble to fill in the pit in which it had been trapped. The labourers were just twenty yards from the gate. It was hard for the Roman archers to miss. There was something deeply unnerving about the fanaticism with which the Sassanids leapt forward to replace men who had fallen – leapt forward to certain death. Were they drunk? Were they drugged?
The tortoise edged forward. The rubble in the pit shifted but took its weight. The ram neared the gate.
'Everyone, ready. Here they come. Now!' On Ballista's word legionaries stood up in the face of the arrow storm. Two near the northerner were punched backwards. Without a pause the survivors, grunting with effort, manhandled the huge, dripping-wet bags stitched together from uncured hides and stuffed with chaff over the battlement. The bags fell like massive soggy mattresses. The restraining ropes tied to the parapet snapped taut. The bags slapped wetly against the gate, held in place. Peering over, Ballista saw that he had calculated the length of the ropes exactly. The wood of the Palmyrene Gate was cushioned from the force of the ram. The sodden bags would not burn. Ballista had bought some time. Above the heads of the defenders, the arms of the three cranes swung out.
After only the briefest pause Sassanid warriors poured from the rear of the tortoise. They carried scythes tied to long poles. Through his disappointment Ballista felt a grudging admiration for Shapur and his men. They had been ready for this device. No wonder Antioch, Seleuceia and so many other towns had fallen to them in the time of troubles. These easterners were better at sieges than any barbarians Ballista had ever encountered.
Out in the open at the foot of the gate the Persians dropped like flies. As men fell others sprang out to snatch up the fallen scythes. Bloody fanatics, thought Ballista. One by one the ropes were cut. The bags began to sway and sag. He cursed himself for not thinking to use chains. Too late to worry about that now.
One by one the sodden stuffed hides fell ponderously to the ground. The wooden outer gate of Arete stood unprotected. The great ram surged forward, the horns of its head closing on the gate.
The northerner rose to his feet. He was met by a hail of missiles. With his right arm above his head, he began to guide the grapple of one of the cranes to its target; right a bit, a little more, stop, back a little, down, down, close the claws. Missiles whirled past him. An arrow embedded itself in his shield, making him stagger. Another hit the parapet and ricocheted past his face. The grapple caught the ram just behind its metal head. Ballista signalled for the crane to lift. The chains clanged rigid. The arm of the crane groaned. The grapple slipped a fraction, then held its grip. The head of the ram began to lift slowly, to point impotently towards the sky.
For a moment it looked as if it would work. Then suddenly the claws lost their grip. The grapple slid off. The head of the ram fell free. Again it pointed at the gate. Again the tortoise moved forward until it almost touched the gatehouse. There was no longer any room for a grapple between the two: the opportunity had passed; the device had failed. Ballista dropped back down behind the battlements.
The metal head of the ram drew back under the tortoise, then shot out. The whole gatehouse trembled. The crash echoed down the walls. The gate still stood. The ram drew back, then struck again. Another deafening crash. Again the gatehouse reverberated. The gate still held, but a strange tortured creaking indicated that it could not last long.
With his back to the parapet, Ballista watched Antigonus and another soldier guiding the other two cranes to their target. The massive boulders swung ominously at the end of the chains as they were traversed over the tortoise. A glance at each other and the two men signalled for the boulders to be dropped. As one, the grapples released their load. After a heartbeat there was an appalling crash.
Ducking out from behind cover, Ballista saw at a gl
ance that the tortoise still stood. The boulders had bounced off. The arms of the two cranes were already swinging back over the wall to collect their next load. A Sassanid artillery stone took Antigonus's head off. Without even a fractional pause another soldier stood up to take his place.
The great ram struck again. The tremor came up through Ballista's boots. There was a terrible sound of rending wood. Khosro-Shapur had triumphed again: the outer Palmyrene Gate was reduced to firewood. A cheer started up from the Sassanids working the Fame of Shapur. It faltered and died. They had expected, they had been told, they would be looking down a corridor to another less strong wooden gate. They were not. They were looking at a closely cemented stone wall.
The arms of all three cranes, boulders swinging, arched back out over the gatehouse. Again Ballista stepped into the maelstrom to guide one – right, right, a bit further – Maximus and two of the equites singulares trying to cover him with their shields. An arrow caught one of the guardsmen in the throat. He fell back and his blood splashed over the group. It stung Ballista's eyes. The three grapples released their burden. A thunderous, splintering impact, and two of the boulders smashed through the roof of the tortoise, exposing its soft innards and the men below. Ballista dropped back into cover. There was no point in playing the hero unnecessarily. Maximus and the remaining guardsman landed half on top of him.
There was no need for further orders. Ballista could smell the pitch and the tar. Everything combustible that could be shot or thrown from the walls was being aimed at the yawning hole in the roof of the tortoise. Wishing they had some naptha left to make sure, Ballista closed his eyes, tried to steady his breathing and hands.
'Yes, yes, yes!' Opening his eyes, Ballista saw Maximus peering round the stone crenellations. The Hibernian was punching the air. 'It's burning – burning like a Christian in Nero's garden.'
