scarlet, yellow, violet. Strange, thought Ballista, how the abstract patterns were more threatening than the animals. A bear is just a bear, but who in the Roman army could tell what powers and horrors the minimal and totally alien designs symbolized?
The Sassanids were drawing closer. As their cavalry breasted the slight rise, individuals could be easily made out. They were less than a thousand paces away now. Ballista looked carefully. He could just about determine that some wore pointed helmets and others domed caps, while the majority appeared bareheaded. Now they were less than seven hundred paces away, and advancing at a brisk canter. There were a lot of them. They filled the plain. The thunder of their coming preceded them.
'Steady, boys,' Ballista called as he rode along behind his front line. He had reinforced the two hundred Saracen archers led by Viridius with the three hundred and fifty slingers of Sandario, but the line still looked horribly thin. Light infantry will seldom stand a really determined charge by cavalry. It was a risk, but he did not want to weaken the rest of his formation. 'Steady, boys,' Ballista called again, as much to himself as anyone.
At five hundred paces he could pick out details of the Sassanid riders' accoutrements: flashes of colour, glints of metal, the paler smudges of their faces, the occasional white sock on a horse. The northerner felt a tentative sense of relief. He could see the riders' faces, see the legs of the horses. These were not the feared Sassanid clibanarii, the terrible, heavily armoured men on heavily armoured horses. Ballista's gamble with having only light infantry in his front line might work. These Sassanids were horse archers. These bowmen should have no intention of trying to charge home against an unbroken enemy.
'Hold the line, boys. They are just horse archers. They will never close with us.'
Ballista rode past Acilius Glabrio, to his left at the head of the central column of the army, the cavalry column. 'They will not charge home. Leave them to our infantry. Hold the line,' the northerner called. He did not notice any response from the patrician.
Ballista moved on, offering a few words of encouragement to the front line as he went. Now and then Demetrius would lean over and mutter in his ear, and then he would call out to junior officers and one or two men by name.
'No fear, Dominus. These easterners do not have the balls to face us,' shouted a grizzled slinger.
'True, comilitio, and they are only light cavalry – they are nothing close to the steel,' replied Ballista. He did not add, But the clibanarii, the heavy cavalry, they are out there somewhere, hidden by the drifting dust cloud, waiting, long spears in hand and murder in their hearts, and they, fellow-soldier, they are something, something terrible close to the steel.
Ballista pushed Pale Horse into a canter. The others followed: Maximus, Calgacus, Demetrius, the standard bearer called Bargas, a trumpeter and ten Equites Singulares. The great white draco hissed and snapped above their heads. Ballista had wanted to speak to Sandario, on the extreme left of the front line, before the attack came into range. Now it was obvious that was not going to happen.
Ballista was still some way short when he saw Sandario make the signal: the trumpets called, the slings whirred round and he half-glimpsed the slingshots fly towards the enemy. A moment or two later Roman trumpets rang out behind Ballista. He turned in his saddle and watched Viridius' men loose their bows. Archers on foot outrange those on horseback, and slingers outrange both. For a short time, the Romans were in the god-like position of being able to kill without the least danger of being killed. With a clear view over his own infantry, Ballista could see the effect on the Sassanids. Men were knocked from saddles, some horses went down in a maelstrom of thrashing hooves and dust. But far, far too few to stop the charge.
The bright day darkened and a storm of Persian arrows came slicing down. All around, men were roaring with fury, screaming in pain. Ballista felt an arrow tug at his cloak, saw the sparks as another ricocheted off Pale Horse's armour. He made a signal and turned his tiny column back the way it had come. Everyone feels better with their left, shielded side to the enemy. As if in confirmation of the thought, Ballista was knocked sideways in his saddle as an arrow punched into his shield. Pulling on the horns of his saddle, he hauled himself upright. The bright fletchings of the arrow nodded as he moved, its steel tip embedded in the thick linden boards.
Without conscious thought, Ballista had slipped into the altered state of almost complete calm that sometimes came on him in battle. At the centre of the storm, he looked out over the heads of his infantrymen and tried to work out how the fight was going. Men were falling on both sides. Neither side wore heavy armour. The Sassanids had the advantage of numbers, but the dust and movement made it impossible to judge by how much. On horseback the Sassanids were bigger targets, but then again they were moving.
As the northerner watched, the front rank of Sassanids, no more than thirty paces distant, turned to their right, spun round and headed away. As they retreated they aimed their arrows back over the rumps of their horses, employing the famous 'Parthian shot'. The next rank, and the one after that, and all those following repeated the manoeuvre. Arrows still rained down, but in next to no time the whole force was cantering away.
A great wave of confused noise hit Ballista. It came from up ahead, from near the centre of the Roman line. For a few seconds the northerner could not accept the evidence of his eyes. There was the scarlet and gold figure of Acilius Glabrio out in front of the line. The standard bearers and musicians were with him. Behind him, the column of cavalry surged forward. The heavy cavalry of Equites Primi Catafractarii Parthi were riding through, riding over the line of Roman light infantry. Slingers ran desperately out of the way. One or two, too slow, were bowled over, were either sent spinning like tops or, worse, disappeared beneath the plunging hooves. Acilius Glabrio, scarlet paludamentum flying, was leading his men out in a hell-for-leather charge after the Sassanid light cavalry.
You fool – they are not running, it is just their way. They will turn in a moment. Ballista was not sure if he shouted out loud or not. He found that he had put Pale Horse into a flat-out gallop towards the point where more and more armoured horsemen were pouring out of the Roman formation. Ballista turned in the saddle. His entourage were still with him: Maximus, Calgacus, Demetrius, the others. Good. He called for the trumpeter to sound recall. Towards the rear of the column some of the troopers began to rein in their horses.
Ballista angled his horse into the charging column of catafractarii. His knee crunched painfully into the armoured knee of a trooper. Highly strung for the charge, the trooper rounded on the man who had barged into him then, as he recognized his general, the fight drained out of him. Ballista seized the trooper's reins and pushed their mounts across the four-wide column, bringing those behind them to a skidding halt.
Rising in the saddle, Ballista looked round to take stock. He had managed to prevent about one hundred men of Equites I Parthi leaving the army. But the rest of the unit, some two hundred troopers, were streaming away across the plain.
'Bugger,' said Maximus eloquently. 'Bugger, bugger, bugger.'
Ballista summoned over a decurion. Demetrius quietly provided his name. 'Lappius, I am appointing you in temporary command of those of Equites I Parthi still here with the main body of the army. I want you to get them in order and form them up in close order, knee to knee, in a line two deep, with the right-hand men by the riverbank. Hold that position. On no account move without a direct order from me.' To give him credit, the decurion took this unexpected turn of events in his stride, saluting smartly and barking out orders to make things so.
Staring out across the plain, Ballista watched the rest of Equites I Parthi hurtle towards their fate. They were already some two hundred paces away. The Persians, of course, were giving way before them. But now some of the eastern horse archers were beginning to hang back to lap round their flanks. In a classic manoeuvre, the Persians were drawing the Romans on while flowing around them like water.
Ballista spoke fast but clearly to a messenger. 'Tell Mucapor to bring the Equites Singulares forward. I want them in a line one hundred across and two deep, in open order, a horse's length between each rider, the whole line cantered on me.'
The messenger clattered away. Ballista looked back out over the plain. The majority of the Equites I Parthi still galloped hard after Acilius Glabrio, though now they were strung out like the train of a meteor. Carrying their own heavy armour and their armoured riders, the horses must be nearly blown. Towards the rear, some troopers were slackening their pace. One or two had even stopped and were tuning their mounts.
The jingle of equipment, the stamp of hooves, and the muted grunt of orders announced that his bodyguard, the Equites Singulares, were being deployed behind him, as Ballista wished. He did not turn around, he kept his eyes on the plain. The main group of Roman troopers had come to a halt. He could see the standards still flying above them. They were about four hundred paces away. And the Sassanids were closing around them. Across the
