Suddenly a huge shape burst out from among the Durotrigans in front of Cato: an older warrior, wearing chain mail over a light tunic. His sword arm was raised over his head and the long blade flashed in the sun as it reached the top of its arc. Then, as it slashed down, Cato threw himself into the man’s body, punching his short sword into the chest. It caught on the chain mail, not penetrating, and the man gasped explosively as the blow drove the air from his lungs. His own blow faltered slightly, but because Cato had leaped inside its sweep the blade passed over his shoulder and instead the pommel caught the centurion a shattering blow on the side of his helmet, flattening the horsehair crest. Cato’s jaw crashed shut on the end of his tongue as his vision exploded into a dazzling white for an instant and he fell back on the ground.

He heard a cry, he blinked and his vision cleared. The enemy warrior sprawled beside him, skull cleaved in two. Cato looked up and saw Artax standing over him. Their eyes met, and the Atrebatan noble’s sword rose towards Cato’s throat. For an instant Artax’s eyes narrowed and with a cold chill of certainty Cato knew that he would strike and have his revenge here in the heat of battle where Cato’s death would be easily accepted. Just as Cato tensed himself to try to dive out of the path of Artax’s blade, the Atrebatan smiled and wagged the point mockingly. Then he turned and was gone, lost in the press of men determined to crush the Durotrigans.

Cato shook his head, clambered back to his feet, and pushed forward. He was aware of the splash of water, and realised that the charge of the Wolf Cohort had carried them as far as the ford. One last effort and the fight was over. He could even hear Macro now, bellowing in triumph and battle-rage as he cut through the rear of the enemy column. Already Cato could see the red auxiliary shields and tunics of the other cohort through the shattered ranks of the Durotrigans before him. One of them suddenly looked at Cato, threw his sword into the river and kneeled down, pleading. Before the centurion could respond the Atrebatan warrior to his right thrust his sword into the man’s chest. Cato looked round and saw that more and more of the enemy were foolishly lowering their weapons and trying to surrender. But the blood-crazed Atrebatans continued to strike them down where they stood.

‘Stop!’ Cato desperately shouted above the din. ‘Wolf Cohort! Halt! STOP!’

When the warrior to his right made to strike down his next victim Cato whacked him on the arm with the flat of his sword, knocking the blade from the man’s hand.

‘Enough!’
