The enemy’s formation had broken and now a series of duels were being fought out across the ground in front of the fort. There were plenty of bodies lying on the ground, and Macro could see that perhaps a third of Trebellius’s men were down. The rest were outnumbered and now that the initial impact of the charge had passed, the tribesmen were beginning to have the upper hand, as they heavily outnumbered the Romans. Even as Macro watched, several of the warriors, led by their chief, had surrounded the standard-bearer of the squadron. He held the staff close to his body while cutting at any native that came within reach of the long blade of his spatha. But there were too many of the enemy and one, more daring than his comrades, leaped forward and snatched the reins from the hand of the standard-bearer and savagely wrenched the horse’s head round to unbalance its rider. The chief stepped in and thrust his sword into the Roman’s side, while another man ripped the shaft of the standard away and held it aloft with a cry of glee. Macro could see the mortified expression on the face of the standard-bearer as he used what strength he had left to steer his horse round with his knees and slash his sword across the back of the warrior who had seized the squadron’s insignia. The standard dropped to the ground as the native collapsed and then his comrades fell on the Roman, hauling him from his saddle before they butchered him on the ground.

Macro saw that Trebellius and four of his men were closer to the fallen standard and he cupped his left hand to his mouth.

‘Decurion! Save the standard!’

Trebellius looked round and saw Macro, who stabbed his finger in the direction of the natives who had finished off the standard-bearer and were already making off with their trophy. Their success had encouraged their comrades and Macro saw that the fight was in the balance. He turned towards the fort.

‘Come on, you bastards! Help us!’

The commander of the garrison had already correctly read the situation and even as Macro’s words died on his lips, the gates opened and the auxiliaries quick-marched in tight formation towards the skirmish. Macro felt a surge of relief as he raised his sword again and looked round for a fresh opponent. Then it struck him: there was no sign of Cato. He felt an icy stab of anxiety at the base of his spine as he scanned the scene.

‘Cato! Sir! Where are you?’
