The sun had not yet reached the top of the depot palisade when Centurion Macro emerged from the headquarters building. He was in full uniform, from nail-studded boots, silvered greaves, chain-mail vest with its harness of medallions, right up to the transverse crested helmet, gleaming dully in the shadow of the ramparts. In his hand was a vine cane, symbol of the right conferred upon him by the Emperor, Senate and People of Rome to beat the otherwise sacrosanct body of a Roman citizen. He twirled the cane between the fingers of his right hand as he marched up to the silent mass of natives gathered together on the depot’s training ground. Since news of the formation of the native cohorts had spread from the Atrebatan capital, thousands of men from the surrounding lands joined those from Calleva in coming forward to be selected.

After nearly two months in hospital recovering from his head wound, Macro felt good to be getting back to the familiar routines of a centurion’s life. No, he corrected himself, barring the odd skull-splitting headache, life didn’t just feel good, it felt bloody marvellous. He puffed out his chest, whistling contentedly to himself as he approached his new recruits.

Centurion Cato was standing to one side of the crowd, talking with Tincommius. It was the first time that Cato had worn the uniform and equipment of a centurion and Macro thought it suited him no better than that of an optio. Cato was tall and thin, and the chain mail seemed to hang on the youngster rather than fit him. The vine stick was held awkwardly and it was difficult to imagine Cato wielding that across the back of some recalcitrant legionary, or even one of these natives. Cato’s recovery in hospital had been unkind to his already skinny body and the muscle wastage to his legs was evident in the way that the back of his greaves actually overlapped slightly.

Tincommius, by contrast, was evidently in rude health, and though even taller than Cato, he was broad in proportion and looked like he might be quick on his feet as well as strong. The young Atrebatan nobleman had been tasked by his king to serve as translator and advisor, and was keen to learn the ways of the Roman legions. Tincommius could only have been a year or two older than Cato, and Macro was pleased to see them laughing together as he strode over to join them. Let Cato befriend the man then; it would save Macro having to. The older centurion had an instinctive distrust of most foreigners, and all barbarians.

‘Gentlemen,’ he called, ‘we’re not here to crack jokes. There’s a job to be done.’
