There was far more equipment than Ferox had expected, but it was hard to make much sense of it. Both granaries were crammed with artillery and machines of one sort or another, all swathed in dust and cobwebs, arms and beams overlapping or piled in heaps. Beneath the filth some of them were painted red, blue or green, something he had never seen done on artillery before. He saw a good few scorpiones, some other bolt shooters that seemed to be of a different pattern, but similar size, and many more larger pieces, some of them truly huge. Naso whistled as he reached up to touch the huge bronze washers and the ends of twisted sinew on one piece two or three times taller than he was.

‘Throw a three mina stone at the very least,’ he said. ‘Not sure about the cord though – looks half rotted away. Like a lot of the others. Not sure how many ever worked in the first place, come to that.’

‘Any idea what these are?’ Ferox gestured at a couple of strange devices that were more like cranes than catapults, each with a thick boom pointing upwards.

Naso shook his head. ‘Buggered if I know, sir.’

‘They’re big whatever they are,’ Sabinus said, and then broke down coughing as he swallowed dust. Ferox patted the centurion on the back.

‘I want a full inventory. There must be more veterani who have at least a little experience of artillery or who can learn fast. Find as many as you can, Naso. Tell them the Bastard wants this lot sorted out – and then point out that it’s lighter work than clearing ditches and digging pits. But I want to know if there is anything that we can put to use. So tell me what works, if any of it still does, what could do with a little attention, anything else that might be made to shoot and then whether there are parts or scrap we can use for anything else.’

‘I have a book about engines,’ Sabinus said, finally recovered from his bout of coughing. His tone was apologetic. ‘My father presented me with a small travelling library of military manuals before I set out for the army. To be honest, I haven’t paid much attention. All seemed a bit dry and abstract when I tried.’

‘I would appreciate a loan, if I may,’ Ferox said.

‘Of course.’ Sabinus hesitated. ‘Do you really think we will be attacked, sir?’

Ferox doubted that the man would understand about instincts. He had already explained what he knew and what he thought it meant that morning and if that did not convince the man, then saying that he ‘knew’ it would happen was not likely to make a difference. Yet he did, and the feeling grew stronger every moment. ‘Yes,’ he said in the end. ‘I hope that I am wrong, but I am sure I am not.’

Sabinus was saved from answering by another bout of coughing. Vindex patted him this time. ‘The centurion tends to be right about things like that,’ he said as Sabinus recovered. ‘But also has a way of winning when all the odds are stacked high against him. And usually those of us with him get through as well.’
