‘Forwards!’ He nudged his horse in the flanks and it obediently advanced. The other men rippled into motion on either side, and then Ajax increased the pace to a trot. There was no point in charging the Romans. He wanted his men to arrive in one wave, to maximise their effect. The arrows continued to plunge down, creating more havoc in the enemy ranks, and for a moment Ajax feared that the Arabs might become too carried away with the effect of their handiwork and keeping shooting even as he and his comrades entered the fray. However, at the last moment, Karim shouted to his men and they obediently lowered their bows.

The mounted gladiators swept into the disordered Romans, getting up close where their shields could be used to strike their opponents and their swords would be more effective than the unwieldy lances. Ajax slashed at the shoulder of the first man who stood in his path. The edge of the blade failed to cut through his chain mail, but the force of the impact still broke bones beneath and the horseman cried out as he swayed in his saddle. Ajax urged his mount on, striking at the man’s neck with a backhanded blow. He did not have time to swing with any force but the blade still found a way under his guard and cut through skin and the spine. As the rider slumped forward, Ajax recovered his sword and steered his mount towards the decurion who sat in his saddle, close to the wounded signifer, protecting the standard. The air about Ajax was filled with dust and the clash and thud as men cursed each other or cried out in pain. A quick glance was enough to tell him that his men were having the better of the fight. Only one of the gladiators had been injured, run through his side with a lance, but it only seemed to have enraged him as he hacked and slashed at the Romans around him with savage fury.

A flicker of light and shadow alerted Ajax to the danger from his side and he threw up his shield in time to block the head of a lance as a Roman made an overhead thrust. The point flicked up, just missing the top of his head. At the same time Ajax swivelled in his saddle and swung his sword in a wide arc with ferocious force. The blade cut right through the Roman’s wrist and the lance clattered to the ground, the severed hand flopping into the dust alongside.

‘Fall back!’ the decurion shouted. ‘Back!’
