smoke. The soldiers prowled around their watch posts, peering out into the dangerous dark.

To Brigonius's surprise, Tullio didn't send his forces out immediately to meet the enemy. During the night the sentries passed only despatch riders. On the old signal tower flags were raised and beacons lit, and across the turbulent countryside more pinpricks of fire lit up in response, as the mass mind of the army channelled and absorbed information about what was happening.

It soon became clear that the uprising had been coordinated. There had been strikes all along the line of the Wall, most of them rash suicide raids. And at the same time there had been a general rising in the countryside, with tax officials and councillors, many of them Brigantian themselves, abused, attacked, their homes ransacked. The most serious rising was to the west of Banna, where a pack of young men had torched the still-incomplete turf wall, kicked in the defensive ditch, and generally made a mess of the Romans' new frontier.

Through the night Tullio sat in his improvised command post, poring over maps and lists of detachment names and numbers on hastily setout tables. Records, charts, lists, information, information: even as the countryside boiled like a disturbed ant hill, communication, patience, thinking was the key to the Roman response. Sitting here Brigonius saw how very wrong Matto had been to resist the Romans' literacy, for it was the army's key weapon. Through words and numbers on paper Roman commanders were able to transmit their commands unambiguously across hundreds of miles, and the bloody lessons of the past were stored without error or distortion, for ever.

While Tullio and his staff worked, the Brigantian slave boy brought them food and more soldiers' wine. Brigonius wondered what was going on in the head of the boy, what he understood of the uprising. Where was his family-north of here, south? But families, even names, were irrelevant, once you were a slave; you had no past, no future, no purpose but that which your master assigned you. Even your children were slaves, and given litter names by your master: 'First-born' (Primigenius) perhaps, or 'Similar', or 'Runt'. But on a night like this, Brigonius thought, even the most docile slave must feel something stirring in his heart.

The long night wore on. Karus drank himself to sleep on a soldier's blanket. Xander, a nervous man surprisingly stoical in the face of a real crisis, wrapped himself in his cloak and sat quietly, eyes wide. Lepidina curled up against Brigonius, and Brigonius welcomed this echo of their brief love, though he knew she wanted no more than comfort. As for himself he could not sleep.

The sun was rising when at last the bugles sang. Brigonius left his companions sleeping, letting Lepidina slide off onto a blanket, and went out to see.

Units of soldiers were forming up, preparing to march out to meet the enemy. Brigonius overheard Tullio and his aides reviewing their information and giving commands to the junior officers. The Romans had delayed their response until they could assemble a sufficient countering force with detachments of the auxiliary units from Banna, other nearby camps, and the forts behind the Wall line. The legionary detachments assigned to Wall construction work were also gathering their weapons, but they were falling back, while other detachments from the legionary fortress at Eburacum, better prepared, were moving forward. The auxiliaries would do the brunt of the fighting while the legions would be kept in reserve, for no large-scale pitched battle was expected…

And so on. This was how the system was supposed to work. Thanks to its fast communications, detailed record keeping and flexible deployment the army, never numerically strong, was able to deploy rapidly and efficiently, focusing its energies exactly where they were needed most. The army itself was a high technology, Brigonius saw, honed and perfected over centuries of conquest.

Meanwhile the soldiers were individually preparing. Brigonius had worked with Roman soldiers for years. While they could sneer at the Brittunculi they had been posted to govern, they had come to seem disarmingly ordinary to him: ordinary fellows doing a job of work, wanting nothing but food, sleep and an occasional shag. But now he saw these men for what they were. In armour that fit like a second skin, wielding weapons with the casual intimacy of a lover's touch, they were barely human at all, he thought; they were slabs of muscles intent only on killing. And as they formed up in their tight disciplined units they seemed more formidable yet. Brigonius's heart felt heavy as he thought of the force that would face them, a rabble of disaffected Brigantian farm-boys stirred up by hotheads like Matto, armed with rusty weapons their grandfathers had been hiding in grain pits since the days of Cartimandua.

A month after the insurrection had been put down, governor Nepos travelled from Londinium to assess the damage for himself.

Nepos toured the forts and rode the length of the Wall, and spoke to his senior commanders, including Tullio. He returned to Eburacum for a few days to preside over the trials of the suspected ringleaders of the rising. And he announced, in the even-handed way of wiser Romans, that he would consider compensation for farmers who had lost significant chunks of land-always providing they could prove they hadn't taken part in the uprising themselves.

Then he came to Banna, where he ordered a review. Tullio, Annius and their staff were called in, as were senior officers from the forts, a couple of tribunes from each of the three legions, and the architect, Xander, with his sponsor Severa, and Brigonius and other local suppliers.

The meeting was fractious from the start. Nepos demanded of Tullio, 'How could this happen, prefect?'

'We had some failures of intelligence,' Tullio admitted, 'which have been put right. A failure of security too which has been tightened.' Brigonius could testify to that; he had the bruises inflicted by gatekeeping soldiers to prove it. 'But,' Tullio went on, 'we just didn't anticipate the way the attack unfolded. The Wall is designed to deal with attacks from the north, not the south!'

Nepos shook his head. 'I still find it hard to believe. This has implications for everything we are doing here. If this were to happen again-'

'It won't,' Severa said quickly. 'Governor, this was a bit of restlessness by unhappy Brigantian farmers. Once your more lenient policies are accepted-'

Nepos glared at her until she was silent. 'Madam, to my mind we are building for centuries. Perhaps Brigantia will be quiet for a season or two. But in time a new generation of young bulls will rise up who will imagine their grandfathers didn't go far enough-I've seen it all before. We must plan for all contingencies.'

A young man in brightly polished dress uniform stood and took the floor. 'And that isn't all we have to think about.' He bowed to the governor. 'Sir, my name is Galba Iulius Sabinus. I am a tribune of the sixth; my legate at Eburacum sent you his report on the new military dispositions.'

Tullio growled, 'The damn legions didn't deploy.'

'But they might have had to,' Sabinus said with effortless command.

Nepos nodded to the tribune. 'I've seen the report. You may summarise its findings, Iulius Sabinus.'

Sabinus was good-looking, strong-featured, with thick dark hair. Brigonius imagined he might actually be a native Roman-and if he was a tribune he must be of the senatorial class, in the course of a career which might one day lead him to a post like Nepos's own. Brigonius always reminded himself that to men such as Nepos and Sabinus, whatever happened in Britain was but an incident in a long career progression.

'We of the sixth, concerned about the practicality of the Wall even before the uprising, have since mounted a major exercise to test its utility. All this is detailed in the report…'

The idea of the Wall was that in the event of major disturbances to the north, the legions would deploy from their forts in the rear, march through the gates, and meet the enemy in open battle north of the Wall. When detachments of the sixth had actually tried this they hit problems. First you had to walk a few miles to the Wall itself. Then you had to break formation to make your way to one or other of the gates and file through, and just as Tullio himself had anticipated, legionaries in full battle armour found themselves queuing behind farmers' wagons and herds of sheep. Even on the other side of the Wall you then had to form up again into marching order. During all this time you were terribly vulnerable to attack.

'It just didn't work,' Sabinus said with bold bluntness.

Tullio said, 'In fact it's worse. In some places you have to cross the river to get from the forts to the Wall! The Wall's been my baby, and I hate to say it, but we should pull down the whole wretched thing. We did better under Trajan without a Wall at all.'
