Macro looked back at the distant figures of the horsemen following them. He frowned for a moment and then nodded to himself. ‘All right. You take him on. I’ll try to delay those bastards for as long as I can.’

Symeon stared hard at him. ‘Leave him.’

‘What?’

‘I said leave him.You won’t delay them long enough for the two of us to get away. Either he dies, or all three of us will.’

‘I can’t,’ Macro said helplessly as he glanced down at Cato’s pale face slumped against his shoulder. ‘He’s my friend. More than a friend: he’s like a son. I won’t leave him to die.’

Symeon glanced at their pursuers and then turned back to Macro with a grim expression.’All right, you lead him on. Stay on the track. I’ll ride with you and hold them off.’

‘What with?’

‘This.’ Symeon raised his bow. ‘A few miles further on the track branches off towards a village.There’s a winding gully beside the road. When we reach it, do exactly as I say. Understand?’

Macro stared a moment, tortured by doubt, then nodded.

‘Good! Now let’s go!’

They rode on, either side of Cato, bracing his limp body so that he stayed in the saddle. But their speed was greatly reduced and every time Macro looked back he saw that the fastest of the enemy riders was drawing closer. Ahead, the rearmost of the auxiliaries was steadily drawing away, a dim shape amid the dust kicked up by his comrades in front of him. Macro cursed them for a moment, before he realised that, because of the dust, the decurion and his men could not be aware of his situation.

Behind them a group of four brigands was swiftly catching up, some distance ahead of the weaker mounts of their comrades. They knew they would soon have the Romans at their mercy and whipped their horses on in frenzied anticipation of catching their prey.

They had ridden down through some hills and now they were emerging on to the plateau: an undulating expanse of stony ground through which a thin strip had been cleared for the track. Symeon steered his horse away from Cato’s and called out to Macro, ‘Keep going. I’ll be a short distance behind.’
