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 glance 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.'
Ballista looked up at his draco flying above the gatehouse. With the south wind hissing into its metal jaws, its white windsock body was writhing and snapping like a serpent. The incoming missiles had slackened. Maximus had been joined by Mamurra and they were looking over the battlements. Demetrius and Bagoas were huddled on the floor. The Greek boy was very pale. Ballista patted him, as if he were soothing a dog.
'They have had enough. They are running'. Maximus and Mamurra rose to their feet. Ballista stayed where he was.
Inexplicably, a group of girls appeared on the roof of the gatehouse. They were wearing very short tunics and a lot of cheap jewellery. There were no more incoming missiles. Ballista watched the girls walk to the battlements. They stood in a line giggling. All together they lifted their tunics around their waists. Baffled, Ballista stared at a row of fifteen naked girls' bottoms.
'What the fuck?'
Mamurra's slab-sided face cracked into a great grin. 'It is the third of May.' Seeing complete incomprehension on Ballista's face, the praefectus fabrum went on, 'the last day of the festival of the Ludi Florales, when traditionally the prostitutes of the town perform a striptease.' He jerked his thumb in the direction the girls were
