Cato spared the traitor no more thought as he pushed his way past the bodyguards to the palisade. On either side legionaries and natives from the Wolf Cohort were hurling anything to hand on to the Durotrigans packed into the street below. There were only a few missiles thrown in return as the heaving mass of warriors made it difficult for any man trying to cast a spear or stone back at the defenders, and far more men were being struck down before the gateway than on it.

‘They never learn,’ Macro shouted into his ear.

‘Yes they do,’ Cato replied breathlessly, still blown from his run back to the gate. He raised his arm and pointed. ‘Look there!’

A short distance down the street were a number of small alleys leading off into the maze of huts clustered about the royal enclosure. The Durotrigans were streaming into the alleys and disappearing from view. Macro turned to Cato. ‘I’ll take care of things here. You find out where those alleys lead and make sure that you cover any approaches to the wall.’

‘Yes, sir!’ Cato turned round and grabbed the nearest native warrior. ‘Do any alleys pass close to the walls of the enclosure?’

‘Some might do, sir.’

‘Might?’ Cato eyed him coldly, biting back on his temper. ‘All right, then, get some men, anyone who’s not on the gate, and send them up on to the wall. I want them evenly spaced. There must be no blind spots. Understand?’

‘I - I think so, sir.’ The man was exhausted.

Cato grabbed him by the shoulders and shouted into his face. ‘Do you understand?’

‘Yes, sir.’

‘Go!’

As the warrior ran off to carry out his orders, Cato turned and pushed his way along the narrow walkway until he was clear of the gate and began to run round the circumference of the enclosure. He had walked the perimeter a few hours earlier, as a diversion from Tincommius’ display, to ensure that his sentries were alert to any dangers. An indirect approach to the walls of the enclosure was no mere possibility; it was a certainty. Now that Tincommius’ final effort to achieve a quick surrender had failed the Durotrigans had no choice but to launch a bloody assault. Somewhere amongst the tangled outlines of thatched roofs the enemy was groping for a way through to the wall.
