It had been a different picture two hours before, when he had mustered his men in the pre-dawn twilight, just inside the river gate of the fortress. All of them bone-tired and aching from broken sleep, unwashed and unfed, none knowing where they were going or why. They had marched out in a ragged column, across the bridge and through the silent civilian settlement with their boots crunching loud on the cobbles. Castus had decided not to tell his men of the nature of the mission until they had a day’s march behind them. He knew so little himself about what lay ahead.
But a winter of route marches had toughened the men up, and with the sun on their backs they soon picked up a good pace. The country to either side was open moorland, then at the seventh milestone they crossed a brook and moved into rolling cultivated hills. It was familiar territory to them all. Castus hung back every few miles and let the men pass him, swatting at his thigh with his staff as he checked them off.
‘Atrectus! Get your spear up off the dirt – it’s not a walking stick! Shoulder!’
‘Sorry, centurion.’
Valerius Atrectus was a red-haired joker, and had often been on punishment back at Eboracum. Beside him marched Genialis, a slow, simple soldier who generally did whatever his friend told him. The worst men in the century for discipline, but Castus regarded them now with a contented smile. All of them were his brothers, his men, his command. He looked towards Evagrius, swinging along in the lead now with the standard over his shoulder, the hornblower Volusius marching behind him, Timotheus bringing up the rear with his easy stride. He checked his section leaders, each in charge of a group of eight: Culchianus, Attius, Januarius… All of them looked keen, disciplined and strong. Ready for whatever he might order. If Castus himself felt the tremor of uncertainty about what lay ahead, he was determined not to let it show.
Flavius Strabo, the governor’s secretary, rode his pony along the verge of the road, remaining apart from the soldiers. Castus had hardly been aware of him when they had left the fort, and the man had said nothing to anyone since. Now, as he moved back up the line, Castus regarded him carefully, sizing him up. He was a smallish, fattish man, and sat badly on his pony, seeming to bounce up and down in the saddle as he rode. He probably only had a year or two on Castus, but with his shining bald forehead and trimmed beard he looked much older. Plainly dressed, but he wore an expensive-looking gold brooch securing his cloak. Castus had little experience of civilians, and little desire to expand on it – they were generally a nuisance anyway, interfering with the work of the professionals. Fine for selling beer or cattle, good at running inns, but little use for much else.
But as he dropped back into the rhythm of the march, Castus was aware that the secretary surely knew much more about the task ahead of them than he did. Stepping down off the roadway, he paced up alongside the man on the pony, trying to appear casual.
‘So how far is this villa we’re heading for then?’ He was not sure how to address the secretary – dominus would surely be too deferential. As far as he knew, the secretary was only a minor functionary.
‘Oh, quite a bit further. Three hours’ march beyond Isurium, I’d say.’
Castus nodded. More or less as he had expected. They could break the march for a few hours at Isurium and make it to the villa before evening.
‘And what about this envoy we’re meeting?’
The secretary turned in his saddle and glanced down with a wry smile. ‘The less you know about him the better, I’d say!’
‘Fair enough.’
They moved on in silence, Castus falling in with his men again. He was sure now that Strabo knew something important about the mission ahead. Either he wanted to talk, but had been ordered not to, or he had been ordered to communicate something but was playing a waiting game. Either way, if the fat man wanted to be mysterious, he would let him. Castus could happily march twenty or more miles a day in complete silence with barely a conscious thought in his head, but the secretary appeared to be the kind of man who disliked silence. Give him a few more miles, Castus thought, and we’ll see how well he fares with his attempt at secrecy.
He did not have long to wait. As they passed the eleventh milestone and trees closed around the road the secretary eased himself off his pony, wincing, and walked along with the reins in his hand.
‘Do you think we might take a short rest, centurion? It’s getting rather hot!’
‘Don’t worry about that. My lot can march five hours a day like this. They haven’t even broken sweat yet. We’ll rest when we get to Isurium, but if you want a lie down you can catch us up later.’
‘Oh no, oh no…’ the secretary said. He was kicking up dust as he walked along beside his horse. ‘I’m sorry if I was a little short with you earlier. You must understand there are some things I can’t openly discuss – or not yet, anyway.’
‘That’s fine. We’ve all got our orders.’
They walked on a little further in silence. The trees opened out, and the sun shone hot on their backs. Castus had been exaggerating about his men not sweating. He glanced at Strabo: the desire to talk, whatever prohibition might be on the man, was almost palpable. Fine then; he would draw him out gradually.
‘Tell me about these Picts,’ he said.
‘Ah, yes, the Picts,’ said Strabo, widening his eyes. They had drawn ahead of the marching men a little – Castus had not noticed. He reminded himself not to become complacent about this man.
‘They live in the mountains and valleys, beyond the settled peoples to the north of the Wall of Hadrian,’ the secretary said. ‘Originally they were a collection of feuding tribes – Caledones, Miathi, Venicones and others. They fought many wars against Rome over the years, whenever they banded together and tried to resist us. Then the emperor Severus marched into the north with a huge army. You’ll have read about Severus in the histories, I expect?’
Castus, of course, had read nothing at all, but he had heard of Severus. The emperor who had built the current walls of Eboracum fortress. He nodded.
‘Severus campaigned against the tribes for three years, but failed to completely subdue them. His army burned and destroyed their homes and killed anyone they could find.’
Castus gave an appreciative grunt. He had always liked the sound of the emperor Severus: clearly a commander who knew the best way to treat savages.
‘However, Severus died before he could finish the campaign. The tribes, though, had been driven back into the deepest and most inaccessible valleys of their homeland, and there they remained for most of the last hundred years, fighting among themselves, giving us no trouble.’
‘Good result,’ said Castus. As he had expected, the secretary had shrugged off his fatigue in his enthusiasm to talk. ‘So then what?’
‘Around twenty years ago,’ Strabo said, ‘there were reports of a new power in the north. The scattered tribes had banded together, to threaten the more peaceable tribes allied to Rome. They were led by the Miathi people, but their neighbours called them the Picts. A name to instil terror, it seems.’
‘Doesn’t sound very terrible,’ Castus said. A thought struck him. ‘Do they really paint themselves blue, these Picts, and ride around in chariots? That’s what somebody told me…’
Strabo chuckled dryly. ‘Oh, they do that on occasion, yes. You’ll see for yourself soon enough. Anyway,’ he went on, ‘the Picts soon overran the settled tribal lands and threatened the northern frontier of the empire. At the same time, the Franks were raiding the coasts of Gaul and Britain too. So, as perhaps you recall, when Maximian was appointed co-emperor he sent a man called Carausius to deal with the situation.’
‘Carausius,’ Castus said. He recognised that name at least. The usurper who had seized control of Britain and the Gallic coast and declared himself emperor of the west. Even now, more then a decade after Carausius had fallen, the legions of Britain were still held in suspicion for their support of him. That, Castus had often thought, explained the poor condition of the province, the dilapidated fortresses, the demoralised troops.
