The first of the Druids passed their position, and shouted to the driver, apparently poking fun at him. Prasutagus grinned widely at the man’s remark and Macro nudged him fiercely.

The second Druid passed them, just as the leader shouted out again, much louder this time. One of the ponies started at the noise and tried to back away. The wagon swivelled slightly, and as the ambushers watched, the body of the driver slowly toppled to one side and fell onto the track.

‘Now!’ bellowed Macro and sprang out of the shadows, screaming his war cry. Cato did the same as he threw himself at the second Druid. To his right, Prasutagus swung his long sword in a dull grey arc into the head of his Druid. The blow landed with a sickening crunch and the man slumped in his saddle. Armed with a short sword, Cato did as he had been trained and rammed it home into the side of his target. The impact drove the breath out of the Druid with an explosive gasp. Cato grasped his black cloak and savagely hauled him to the ground, where he wrestled the blade free and quickly slit the Druid’s throat.

Ignoring the gurgling sound of the man’s dying breaths, Cato looked round, sword held ready. Prasutagus was moving towards the leader. Having survived the immediate rush, the first Druid had drawn his sword and turned his horse. Kicking in his heels he rode straight at the Iceni warrior. Prasutagus was forced to dive to one side, ducking the sword swipe that followed. The Druid cursed, kicked his heels in again and galloped towards Cato. The optio stood his ground, sword raised. The Druid snarled savagely at the temerity of the man who faced a mounted foe wielding a long blade, armed only with the short sword of the legions.

Blood pounding in his ears, Cato watched the horse surging towards him, its rider raising his sword arm high for the killing blow. Just as he felt a warm snort of air from the horse’s nostrils, Cato snapped his blade up and smashed it down across the horse’s eyes, then rolled away. The horse screamed, blinded in one eye and in agony from the smashed bone across the width of its head. It reared up, front hooves flailing, and threw its rider before bolting across the plain, head shaking from side to side, flinging dark drops of blood. Back on his feet, Cato sprinted the short distance to the rider, who desperately tried to raise his weapon. With a sharp ring of blade on blade, Cato parried it to one side and buried his sword in the Druid’s chest. Terrified by the attack, the two riderless horses bolted into the dusk.
