A spear flew out from the Durotrigans gathering on the ground in front of the great hall, and Cato jerked his shield up, just in time to block the iron tip. With a jarring crash the spearhead burst through the leather backing, just to the side of his helmet. A cheer went up from the Durotrigans for the warrior who had nearly speared himself a Roman centurion. At once the shield felt heavy and unwieldy and Cato cursed his luck. Once the enemy closed in, a shield was just as vital as a sword, but encumbered with the shaft of a javelin Cato would be at a serious disadvantage. He called out over his shoulder. ‘Get me a shield!’

Those Durotrigans close enough to hear the order jeered him and those who fought with no armour brandished their bare chests in contempt. The incident had drawn together the spirit of the Durotrigans in that indefinable way that feeling flows through a mob, and it was clear that they would charge any moment now.

‘Sir!’ a voice called out behind him, and Cato looked over his shoulder. Mandrax held a shield out to him.

‘Whose?’

‘From one of our dead, sir.’

‘All right, then . . .’ Cato glanced quickly along the front of the enemy mob: they were all cheering, spears and swords thrusting up into the sky.

He threw his shield forward and turned and snatched the spare from Mandrax, quickly raising it in front of his body. Macro and his men still struggled towards the redoubt, hacked from all sides. A steady clatter and thud of blades and spear tips striking the legionary shields accompanied their progress. The men facing Cato turned towards the sound, and their shrill cries faded. Here was a chance, Cato decided, his heart racing.

‘Make ready to charge,’ he said, quietly enough for just the Wolves to hear. ‘And make it loud!’ He allowed a few breaths for the men to brace themselves up, then, ‘Charge!’

Cato gave full voice to a wild animal roar, and the shrieks and cries of his men rang in his ears as the Wolves rushed forward. The Durotrigans turned back towards the small body of men they had been about to massacre, shock and surprise on their faces, and they had not moved when Cato and the Atrebatans slammed into them. Several were struck down before they could resist. Cato smashed his shield boss into the ribs of a thin man, who grunted explosively and collapsed to the ground, gasping for air. Cato kicked his boot down on the man’s face for good measure and stepped over him, thrusting his sword at the next enemy who came within reach. His sword was parried at the last moment, but the desperate swipe at the centurion’s blade left the man’s side exposed to the Atrebatan warrior beside Cato and his guts were ripped open by a slashing blow.
