The other officers stamped their feet in approval and Quertus basked in their praise until he lowered his arms and they instantly fell silent again. He turned to Cato with a cold smile of satisfaction. ‘These officers are my brothers. They command my horse squadrons.’ He indicated them each in turn. ‘Fermatus, Cremax, Stellanus, Pindarus, Mithridates and Miro. Brave warriors all. Those others,’ he nodded to the legionary centurions, ‘they are infantry. Centurions Publius Severus and Gaius Petillius. They are tasked with defending the fort, since that is all they are fit for.’

The two centurions flushed with anger and shame but dared not respond to the insult directed at them. Quertus glared contemptuously at them before he turned his gaze back to Cato and cocked his head slightly to one side.

‘For months now we have waged our war against the Silurians, without interference from the legate at Glevum. I did not request anyone to replace Prefect Albinus. With respect, sir, you are not required, nor wanted here. You should return to Glevum. Tell the legate that I am carrying out his orders and will continue to do so until Silurians only exist in memory.’

Cato could see the blood draining from Macro’s face as he listened to this torrent of insolence and feared that his friend would intervene. He stepped between them and faced Quertus.

‘Centurion, you don’t get to say who is required here and who is not. You, and I, are subject to the rules and regulations of the Roman army. We have both sworn an oath to the Emperor to obey those he places over us without question. I have been ordered to assume command here and you will recognise my authority to do so. We both know the severe penalties that are applied to those who refuse to obey their orders. In recognition of the success of your operations here, I will, on this occasion, overlook your insubordination and put it down to the consequences of the zeal with which you have taken the war to the enemy. But I will not tolerate such behaviour from you again. Is that understood?’

Quertus stared at Cato with a bemused expression that only angered, and alarmed, Cato even more. Quertus bowed his head mockingly.

‘As the prefect wishes . . .’
