Festus preened at the praise of his men. ‘Good men, all of them. Sensible too. No sense in buggering off and losing that fat bounty they’ll get on discharge.’

‘And I take it their families were left back in Germania at the main castra?’ Ferox guessed at least half the men, and probably more, had ‘wives’ and children. Army regulation said that soldiers were not to marry, but men were men, and few wanted to wait out twenty-five years before finding the right woman and starting a family. The army turned a blind eye, knowing that it was better that way.

‘Well, it’s rough up here, the winters savage,’ Festus said.

‘And they were told that we would not be here long enough to make it worth putting the families through the hardships of the journey,’ Sabinus added, his tone dubious. ‘And…’ he trailed off, before rallying. ‘A few were allowed to come anyway, and a dozen or so more made it up here with the last big supply convoy.’

‘Soldiers’ women tend to be a tough bunch,’ Ferox said. He did not add what Sabinus, Dionysius and many of the veterans – if not perhaps Festus – understood. Fear of losing the discharge bonus due in a couple of years was one incentive to keep the legionaries away from the temptation of running. Even bigger for many was the knowledge that running meant that they would most likely never again see their families, and that these would be evicted by the army and sent away with nothing. Someone high up had worked this out, realised that I Minervia had more than its share of men nearing the end of their enlistment, and formed this vexillation – and another sent further to the east – to serve in this out of the way, bleak outpost in the belief that they were least likely to be lured away into Dacian service. The same was true of most of the auxiliaries, notably sixty men from cohors I Hispanorum veterana, whose main base was far away in Thrace, and all of whom had served at least twenty-three stipendia.

It was a bright, if cynical, idea, and had worked well, at the cost of creating a garrison of elderly soldiers, all of them, to quote Sabinus, ‘not happy’. There was almost none of the laughter and life that women and especially the children brought to most big army bases. Piroboridava was quiet, not helped by the fact that it had been built for a garrison twice the size of the one there now, even including the Brigantes.

The place of his men in this grand design still puzzled Ferox. If someone had decided that the old sweats sent to Piroboridava were the men least likely to desert, then why add the Brigantes, full of men almost bound to run, if they did not mutiny first. Were they seen as such a nuisance that senior officers wanted them to desert and rid the army of a problem? Or was this a test of him and the men, to see how they coped, challenging them to come to heel and redeem themselves. Then again, maybe someone judged that the veterans would keep the Brigantes in line. Ferox was not sure, and did not ignore the possibility that this was all a mistake, that a senior officer had written the wrong destination on the order and no one had dared correct him. He almost smiled at the thought – almost. With the army you could never quite be sure, but his instincts all still told him that somebody was playing games, and using them all as pieces on a board.
