Plautius leaned forward angrily. ‘We marched as fast as we could, damn it! Our heavy infantry cannot be expected to outpace native troops. The speed of our troops is not the issue. We had them in a trap and if the Second Legion had done its job properly the trap would have worked perfectly. Vespasian should have made sure that the ford was adequately protected. One cohort was not enough. Any fool could see that.’

‘One cohort was ample, for the job it was actually given,’ Vespasian snapped back.

For a moment the two senior officers glared at each other, eyes glinting with the wavering reflection of the lamp flames. Then the general eased himself back in his seat and turned to Narcissus.

‘I want this man out of my army. He is not competent to command a legion in the field and his insubordination cannot be tolerated.’ He turned back towards the legate. ‘Vespasian, I want your resignation. I want you out of here, on the first ship back to Gaul.’

‘I bet you do,’ Vespasian replied coldly.’If I’m not around to defend myself against any charges you bring, it doesn’t take a genius to work out the consequences. I refuse to resign my command, and I’ll put that in writing.’

Before Plautius could respond Narcissus coughed. ‘Gentlemen! That’s enough of this. I’m sure the fault is not wholly on one side or the other.’

Both officers turned on him angrily to protest but the Imperial Secretary quickly raised a hand and continued speaking before they could interrupt him. ‘Since you are both adamant that the blame lies with the other I fear your testimonies in front of the senate would only serve to destroy you both. Therefore, it seems to me that the best solution is to have an immediate inquiry and find some culpable character lower down the chain of command. If you can make a swift decision and deliver a suitably draconian punishment then I’m sure we can satisfy those back in Rome who demand action in response to your failure.’

Plautius visibly winced at the last word but immediately accepted the lifeline being handed to him and the legate.

‘Very well.’ Plautius nodded. ‘A court of inquiry, then. The legate and I will act as presiding magistrates. At least you’ll agree to that, Vespasian?’

‘Yes, sir.’

‘Then I’ll issue the orders at first light. Statements will be taken by all the relevant officers at once. If we move quickly the matter can be solved in a few days. Will that satisfy the Emperor?’
