Tullius turned to give his orders.’You know your positions. Go to them.’

Cordus headed towards the right-hand redoubt where his men clustered, ready to hurl their javelins into the flank of the approaching enemy. Macro had been assigned the redoubt at the other end of the defences, and the centuries of Antonius and Tullius were to hold the length of wall in between.

‘What about my men, sir?’ Cato asked.

‘Take what’s left and form them up behind the gate. You’re the reserve. If they force the gate, you must keep them out, at all cost.’

‘Yes, sir.’

Tullius drew his sword and picked up his shield, then snarled at Cato. ‘Go. Get out of my sight.’

Cato saluted and quickly climbed down from the rampart. The survivors of the Sixth Century were already rising wearily to their feet at his approach. He did a quick head count and found that he had forty-six men left.

‘Septimus!’

‘Yes, sir.’ The optio snapped smartly to attention.

‘Get ‘em formed up behind the gate. Swords drawn and shields up. We may be needed in a hurry.’

While the optio quickly marshalled the legionaries into position Cato went over to examine the gateway. A few timbers had already started from their rope fixings after the impact of the first assault.

He turned back to his men. ‘First section! On me.’

Two men stepped out of formation and came trotting over to him.

Cato frowned. ‘Where are the rest?’

‘Dead and missing, sir,’ one of the legionaries replied. ‘We were pretty badly carved up out there on the track.’

‘Right,’ Cato responded tersely, and looked beyond the man to the rest of his unit. ‘Second section, on me.’

Five more men came over and Cato indicated the gate. ‘We won’t need to open that again. I want it strengthened. Use the cart, turn it on its side and push it hard up against the gate. Once you’ve done that, start digging and get the earth piled up behind. Leave your shields at the foot of the rampart. Now, move!’

They ran off to do his bidding and Cato went over to join Septimus in front of his men, standing ready to reinforce any weak point in the defences. From the far side of the rampart came the roar of the enemy, charging home. A handful of arrows and light javelins arced over the palisade. With a sharp metallic ring the helmet of one of Tullius’ men snapped back and he fell from the wall, tumbling down the reverse slope of the rampart to lie still on the ground.
