‘Indeed not, sir.’ Sinius nodded. ‘Bad enough that the Germans have been tasked with guarding the mint and the silver convoys as it is. That should be work for proper soldiers, legionaries, or a cohort of the Guard.’

‘Seems that we are not to be trusted by the Emperor,’ Balbus said ruefully. ‘Too many senior officers playing at politics in recent years. And this is what the rest of us have to put up with. Anyway, there’s nothing we can do about it.’ He drew himself up in his saddle. ‘Have your men form up either end of the wagons. As soon as the auxiliaries are out of the way we can proceed.’

‘Yes, sir.’ Centurion Sinius saluted and turned away to call out the orders to his men. As the Germans grumpily formed a single column beyond the wagons, the mounted men eased their horses into place and soon the two small forces were ready to part company. Balbus approached Centurion Arminius to issue his parting instructions.

‘You’re to return to Narbonensis as swiftly as possible. Since I won’t be there to keep watch on your men, don’t let them cause any trouble in any settlements you pass through on the way back. Understand?’

The centurion pressed his lips together in a tight line and nodded.

‘Then you can be off.’

Without waiting for a response, Balbus turned his horse in the other direction and trotted back to the head of the small column where Centurion Sinius was waiting. He waved his arm forward and gave the order for horsemen and wagons to advance. With a crack of the reins from the drivers, the wagons began to move with a clatter and deep rumble from the heavy iron-rimmed wheels. The clop of the hoofs of mules and horses added to the din. Balbus rode on without looking back until he reached the rocky outcrop. Then he glanced round and saw the rear of the auxiliary column a quarter of a mile down the road, tramping back towards Gaul.

‘Good riddance,’ he muttered to himself.

The wagons, with their new escort, followed the road round the rocks and the route resumed its straight direction, through another quarter of a mile of pine trees, towards Picenum. Now that he was well clear of the German troops Balbus felt his mood improve. He slowed his horse until he was riding alongside Centurion Sinius.

‘So, what’s the latest news from Rome?’

Sinius thought for a moment and replied with an amused smile. ‘The Emperor’s new squeeze continues to tighten her grip on the old boy.’

‘Oh?’ Balbus frowned at the coarse reference to the Empress.
