‘Bollocks. Hamedes was a spy. Spies are supposed to be good at winning trust. In any case, he didn’t fool you in the end. You saw through him, and put a stop to his treachery,’ Macro concluded bitterly.

Cato looked at him and saw that his friend was struggling to hide his true feelings. ‘His betrayal hit you hard, didn’t it?’

‘Yes . . . I liked the lad. I thought he showed real guts in going into that valley to find Ajax’s lair. Now I know it was all a sham. That bastard fooled me good and proper.’

Cato felt the need to offer his friend some crumb of comfort. ‘For what it’s worth, I think he admired you, despite being your enemy.’

‘Even if that’s true, what does it matter? Hamedes was Ajax’s man. If I’d known, then I’d have killed him with my bare hands, without hesitation. I feel a bit of a fool, Cato. That’s all there is to it. Good riddance.’

‘Yes, of course.’ Cato nodded, and knew it would be best to drop the subject. ‘Macro, I need your help. I fear that we’re in for the hardest battle we have ever fought.’

The first rays of the rising sun were angling across the low hills to the east as the Romans marched out of the camp at Karnak. The auxiliary cavalry led the way, its squadrons stretched out across the army to screen its advance. The main column was led by an auxiliary infantry cohort. Then came the legionaries, weighted down by their armour and the kit fixed to their marching yokes. Their helmets hung from brass hooks on their belts and the men wore light cotton headscarves to shield them from the glare of the coming day, and soak up the sweat from their scalps.

Long shadows were cast across the dust kicked up by preceding columns and from a short distance away, where Cato and Macro rode at the head of the small group of staff officers, the men appeared as dim figures amid the orange haze of dust. Behind the legion came the baggage train, together with the carts carrying the legion’s complement of bolt throwers. There were rations for seven days and if the Nubians chose to fall back for any reason, Cato knew that he could only afford to pursue them a short distance. Prince Talmis would be certain to strip the land of supplies ahead of the Romans.

Tribune Junius edged his mount forward until it drew alongside the new commander of the army. He was silent for a moment and then coughed.

‘What is it, Tribune?’ asked Cato.

‘Sir, I was wondering what your plans are for the coming battle.’

‘To defeat the enemy.’

‘Yes, of course, sir. Goes without saying.’

Macro turned to look at the tribune with a wry expression. ‘So what more is there to say?’
