There was a sudden scream in the crowd, sliding into a high-pitched wail of grief and those nearby turned to look for its source. A woman stood with her hand to her mouth, teeth clenched into the flesh above her thumb as she gazed wide-eyed at a head being held up to the crowd by one of Cato's men. She wailed again, then lurched forward, snatching at the lank locks of hair, matted with dry blood. The warrior raised the head higher, out of her reach, and laughed. The woman shrieked, tearing at his arms, until the warrior cuffed her to the ground with his spare hand. From there she lapsed into sobbing that welled up from the pit of her stomach, and she shuddered as she clasped the hem of the warrior's tunic and begged.

'What's that all about?' asked Cato.

Like everyone else, Tincommius had been watching the confrontation. 'Seems that the head belongs to her son. She wants it for burial.'

'And its new owner wants it for a trophy?' Cato shook his head sadly. 'That's tough.'

'No,' muttered Tincommius. 'It's dishonourable. Here, take this.'

He thrust the Wolf standard at Cato and pushed himself between the woman and the warrior still holding the severed head aloft. Dragging the man's arm down, Tincommius spoke angrily, indicating the woman as he did so. The warrior shifted the head behind his back and responded with equal anger and indignity. At his words the people crowded around and shouted their support, although, Cato noted, a handful kept silent, implicitly on the side of Tincommius. The Atrebatan prince was in no mood to brook any disrespect to his rank, and suddenly smashed his fist into the warrior's face. The people around them shrank away as the warrior staggered back. Tincommius instantly kicked him hard in the stomach to wind him and keep him down. As the man snatched for breath, open-mouthed and staring wildly at his attacker, Tincommius calmly eased his fingers from the stiff hair of the severed head and gently offered it to the woman. For a moment she was still, then with a pained grimace she reached out for all that was left to her of her son. Oblivious to her grief, most of the crowd howled in protest and angrily pressed forward round Tincommius.

'STOP!' Cato cried out, drawing his sword and raising the Wolf standard above his head to command attention. 'SILENCE!'

The protests died away, and everyone looked towards Cato with hostile expressions, resentful of his intervention, yet nervous enough of the men of Rome to be wary of his wrath. Cato's eyes swept over the crowd, daring them to defy him, then came to rest on the woman sitting on the ground, cradling the head in her lap as she stroked its cold cheek.

Cato felt a great pain inside his chest as he watched the woman for a moment, empathising with her heart-rending sorrow. Then he swallowed and steeled himself before he looked up again at the crowd. He had to please these people, give them what they wanted for the sake of the alliance between Rome and the Atrebatans, however much it revolted him.

'Tincommius!'

'Centurion?'

'Give the head back to this man.'

Tincommius frowned. 'What? What did you say?'

'Return the head to this man. It's his trophy.'

Tincommius stabbed a finger at the woman. 'It's her son.'

'Not any more. Now do it.'

'No.'

'I order it,' Cato said quietly as he stepped up to Tincommius so that their faces were no more than a foot apart. 'I order you to do it… right now.'

For a moment Cato read the determination to defy the Roman in those striking blue eyes. Then Tincommius breathed deeply and glanced away at the faces of the crowd. He nodded slowly.

'As you command, Centurion Cato.'

The Atrebatan prince turned towards the woman and spoke gently to her as he reached out a hand. She looked at him in terror, still stroking her son's cheek, then shook her head. 'Na!'

Tincommius squatted beside her, speaking softly and he nodded towards Cato as he eased her hands away from the head. She regarded the centurion with a look of icy, fanatic hatred, until she was aware that the head was being taken from her. With a scream she snatched at it, but Tincommius pushed her down with his spare hand as he thrust the grisly trophy back to the warrior with the other. The man could not disguise his surprise and joy at having the head returned to him and instantly raised it up high; the crowd roared in triumph at the gesture.

The woman reached forlornly towards the head one last time, but Tincommius held her down, and she suddenly turned on him and spat into his face. The Atrebatan prince recoiled in surprise and with a last snarl the woman curled into a ball on the ground and wept bitterly. Cato pulled Tincommius away from the scene.

'It had to be done. There was no other way. You saw how the crowd reacted.'

Tincommius slowly wiped the spittle from his brow before replying.

'But it was her son. She had a right to do him honour.'

'Even after he'd betrayed his people? Betrayed her?'

Tincommius was still for a moment. Then he nodded slowly. 'I suppose so. I suppose it was necessary. I just felt…'

'I know how you felt.'

'Do you?' Tincommius looked startled for an instant, before his expression recomposed and he nodded. 'I suppose even a Roman understands grief.'

'You can count on it.' Cato gave him a faint smile. 'Now take the standard, and get yourself back to Centurion Macro.'

Fortunately there were no more such scenes as Cato and Bedriacus pushed themselves through the throng towards the entrance to Calleva. To one side of the gate Verica stood on a wagon, surrounded by his nobles and the royal bodyguard. Cato caught sight of the Boar standard unsteadily making its way over towards Verica and turned round to pull Bedriacus within earshot. The centurion pointed towards the Atrebatan king.

'Come with me!'

The hunter nodded, and before Cato could stop him, Bedriacus ploughed into the throng, roughly shoving his people aside to make way for his centurion. For a moment Cato feared that the mood might turn nasty, but the Atrebatans were in too good a humour to take offence. A huge quantity of the local beer had already been consumed during Calleva's celebration, and the returning soldiers were doing their best to make up for lost time as unstoppered jugs were passed around. Despite the hunter's best efforts it still took a long time before Cato finally joined Macro and Tincommius. After the tight, heaving mass of the excited tribe Cato was relieved when he finally managed to squeeze through the shields of the bodyguards into King Verica's presence.

'Centurion Cato!' Verica smiled, raising a hand in greeting. 'My heartiest congratulations on your victory.'

'The victory is yours, my lord. Yours, and your people's. They deserved it.'

'High praise indeed, from an officer of the legions.'

'Yes, my lord. And I'm sure the men will continue to justify your pride in them.'

'Of course. But for now we must let them celebrate.' Verica turned to Macro. 'I'd like to hear the whole tale after you've rested. Please be my guests tonight in my great hall.'

Macro bowed his head. 'We'd be honoured, my lord.'

'Very well, until then.'

Verica was helped down from the wagon. He turned towards the gate and his bodyguard quickly formed round him and opened a path through the crowd.

'Come on,' said Macro, after he had passed the word for the cohorts to reassemble in the depot the following morning. 'We've got to get that convoy inside the depot before the locals recover their wits enough to ransack it.'

Once Macro and Cato had escorted the supply wagons through the gatehouse into Calleva, it quickly became clear that many of the Atrebatans were not in a celebratory mood. Small groups of men squatted outside some of the huts, staring silently at the wagons as they trundled along the rutted street towards the depot. Only the children seemed oblivious to the tense division of sympathies in Calleva, and ran happily alongside the wagons, laughing and teasing the drivers. A rumour had carried through the town that some of the supplies would be distributed to the townspeople, and even the children were excited by the prospect of filling their bellies.
