‘Hold!’ Macro yelled, bracing his feet apart and pushing his shield out, ready to absorb the impact of the charge. Cato and the others followed suit and crouched, swords ready, sweating under the weight of their armour and the exertion of scrambling ashore and up the bank. The leading camel’s neck stretched out above the rim of Macro’s shield an instant before its heavy chest struck it a glancing blow. The rider reached out and forward, slashing down with his curved blade, which split the rim of the shield, leaving the tip a few inches from Macro’s head. The Arab was at the limit of his reach and Macro rose up and hacked into the neck of the camel instead. The beast’s jaw fell open and the tongue shot out as it gave a deep bleat of agony, then swerved aside, away from the small knot of Roman soldiers and straight across the path of the other riders. The camel staggered and collapsed on to its knees. Another animal stumbled into its flank, nearly unseating its rider. The rest stopped abruptly or tried to swerve aside. Their riders shouted angrily, struggling to regain control of their mounts, as dust swirled about the long spindly legs of the camels.

Macro instantly sized up the situation. ‘Jackals! At ’em!’

He ran round the stricken camel as its rider tried to recover his balance and threw himself into the confusion of the riders and beasts beyond. Keeping his shield up, Macro hacked at the dark skin of a bare leg that appeared in front of him. Then, as the rider yelled and steered his mount away, Macro turned and saw another man above him, black against the glaring sun. Squinting, he could not see the blade he knew was slashing down towards him and could only throw up his sword arm to try and block the blow. There was a resounding clang of metal on metal and then the shock of the impact driving down Macro’s arm, wrenching his strong wrists and the powerful muscles bunched around his elbow and shoulder joints. The Arab’s blade struck the transverse crest of his helmet, breaking through the bronze strip and finally striking the iron reinforcement ridge that crossed his helmet from side to side. The blow would have killed him outright had he failed to block it, but the impact dazed him, blinding his vision with white sparks. He staggered, weaving from side to side, still holding his shield up while his sword arm hung limply at his side. A wave of nausea seized him and Macro feared that he might pass out.

‘The fuck I will,’ he growled to himself.
