He clenched his fist and smacked it against his thigh in frustration. Anything could have happened. Caratacus might have been driven off. The reinforcement column might have been forced to retreat. The battle might still be raging in the confines of the pass. There was still no indication of which of those three possibilities was most likely. He leaned against the wooden rail and closed his aching eyes to rest them for a moment, aware that he felt light-headed due to the lack of sleep over recent days. His limbs felt stiff and heavy and for the first time he began to wonder how many more years of soldiering he had in him. Macro had known many veterans who had served far longer than the twenty-five years they had signed on for. Longer than was good for them, frankly. But the army was inclined to overlook the handicap of their advanced years due to the invaluable experience they had accrued while serving in the legions.

As for himself, Macro, like many old sweats, had dreamed of retiring to a small Etruscan farm, with a handful of slaves to work it for him, and spending the evenings in a local tavern reliving experiences with other veterans. Now that prospect was growing ever more imminent, he realised that he regarded the idea with disdain . . . quiet despair even. Soldiering was all he knew. All he cared about. All he really loved. What was life without the routine, camaraderie and excitement that encased him like a second skin?

His mind wandered for a moment, losing itself in the warm fug of pleasing memories, and then he was jolted into wakefulness by a sharp pressure on his chin and he stirred quickly, eyes blinking open. His head had drooped so that the flesh under his chin had caught on a splinter on the rail. He bolted upright, horrified at the idea that he had allowed himself to fall asleep, even for a moment. The penalty for doing so while on sentry duty could be death. That he was not on duty was no excuse, Macro chided himself bitterly. It was unforgivable and he glanced round the tower to see if either of the two men keeping watch had noticed. Fortunately their attention was on the enemy camp and he allowed himself a brief sigh of relief. Nothing he could do would affect the outcome of the action in the pass. It would be better to allow himself a rest and get something to eat while the situation was calm around the fort. He would surely need his strength later in the day.

Casually stretching his shoulders, Macro crossed to the ladder. ‘I’ll be at headquarters. If there’s any sign of the prefect, or our column, or anything else, send for me at once.’

‘Yes, sir.’ One of the sentries bowed his head.
