Ajax and Karim heaved themselves up on to the ledge and stood alongside the handful of men defending the wall. A few bodies littered the open ground and the head of the Roman column stood off, twenty feet away, shields protecting the soldiers from the missiles angling in from each side as well as from above. Every so often one of the Romans would bob up to hurl a javelin at the defenders. They had little time to take careful aim before they quickly ducked back behind their shields.

'What are they waiting for?' Ajax muttered to himself.

He had barely spoken when he saw a slow ripple passing down the centre of the Roman column. Then, over at the breach, he saw more men spilling out into the gap between the curtain wall and the temple. They wore the conical helmets and scale armour of auxiliary archers and carried wooden screens with them. The screens were quickly set down and the supports kicked back and then the archers set to work targeting the Arabs on the pylons and the walls of the temple. Ajax paid them little regard, he was more concerned by the activity within the column of legionaries. The shield wall at the front of the formation abruptly parted and a small party of men ran forward with a ramp made from lengths of palm logs tied to a ladder. Another party carrying a second ramp rushed out behind them and they made straight for the barricade.

'Shoot them down!' Ajax shouted, thrusting his arm out. The nearest archers on the roof of the temple turned at once, aimed down and loosed their shafts. Two men fell, one clutching at the arrow that had passed through his thigh, the other shot through the neck. But the ramp carriers ran on. When they reached the wall, the leading pair heaved the end of the ladder up and the poles clattered down on the top of the barricade. At once the nearest Roman soldiers broke ranks and surged forward, boots thudding down on the ramp before the defenders could push it away. Ajax thrust at the poles of the second ramp before the first of the legionaries reached it and the ramp grated back and then toppled to one side. The iron nails of the boots of the leading legionary scraped on the palm logs as he charged up towards the defenders. Ajax glimpsed the shield above him, and the sword blade rising up, gleaming as it caught the light from one of the archers' braziers. He hacked horizontally, beneath the rim of the shield, and the edge of his blade bit into the Roman's shin, just above his ankle, cutting through flesh and muscle before shattering bone. The man let up a shrill cry as his leg gave way and he fell back on the legionary behind him. The second man was knocked off balance and fell off the ramp, together with his wounded comrade, and both landed with a heavy clatter as their armour and shields struck the ground.

The next men rushed up the ramp. This time the leading soldier was more wary, keeping his shield low as he reached the top of the wall. Ajax held his sword hand back as he grasped the edge of the shield and gave it a quick wrench. He managed to pull it at an angle, exposing the thigh and side of the legionary. The gladiator to Ajax's left was armed with a spear and instantly took advantage of the opening to thrust into the Roman's leg. The strike was quickly made and lacked the force to make a crippling wound. Even so, the legionary groaned and drew back momentarily. Then, realising that there was no retreat for him, as his comrades pressed from behind, he came on again, punching his shield out and striking Ajax on the chest. There was nothing Ajax could do to avoid the shield and he rode back with it and fell off the wall, crashing down on to the Arabs waiting beneath. Two of them broke his fall and they collapsed under the bulky weight of the gladiator. The landing drove the wind out of his lungs and for a brief moment Ajax lay stunned on top of the squirming Arabs. Then he struggled back on to his feet and looked up to see that the spearman had struck again, this time into the legionary's groin, and the Roman doubled up, dropping his shield. Karim had climbed up into Ajax's place and now finished the man with a deep cut into his exposed neck. The Roman collapsed on to the ramp and slid back a short distance into the next man.

The end of the second ramp appeared on top of the wall again and Ajax shouted up to his men, 'Push it back! Keep 'em off the barricade!'

The head and shoulders of the first legionary to make a run up the second ramp appeared as the only other man on the wall hacked at the end of the ramp with a heavy falcata. The wood splintered and Karim struck again as the legionary loomed over him. The strut gave way with a loud crack and pitched the Roman over on to the other ramp, right in the path of one of his comrades who stumbled to a halt just in time to stop himself tripping.

'Don't bloody stop! Go! Go forward!' Macro's voice bellowed from the other side of the wall. Ajax felt his heart harden and grasped the edge of the platform. Heaving himself up, he thrust one of his gladiators aside. 'Get off.'

As the man jumped down, Ajax stared into the enemy soldiers milling around below him until he caught sight of the transverse crest of Macro's helmet. The Roman was standing to one side of his men, and there beside him was the taller form of another officer – his friend, the prefect. Ajax sheathed his sword and turned to wrench the spear out of the next man's hands. It would have been gratifying to save his enemy for a more lingering death, but Ajax knew that he must seize the chance to strike before it passed. At his side Karim clashed with another legionary attempting to cross the barricade. Ajax ignored the thud of Karim's sword on the Roman's shield and hefted the spear into an overhand grip. He raised it up above his head and drew his arm back as he took aim at the two officers. A grim feeling of satisfaction filled his mind as he recalled a similar situation back on Crete when it was Macro who was defending a wall and had hurled the spear that had killed one of Ajax's closest companions.

He breathed deeply and then exhaled in a long, calm breath and threw his arm forward, releasing the shaft of the spear. It flew down from the wall, straight towards the two men.

'Macro! Look out!' The prefect shoved his friend aside an instant before the spear would have caught him squarely in the chest. Instead it struck the prefect, high on the left shoulder, the impact sending him sprawling into the sand and grit of the open ground before the temple wall.

'Ha!' Ajax snarled though gritted teeth, his face fixed in an expression of savage triumph. He just had time to spare the two officers one last look, as Macro stooped over his friend, and then Ajax snatched out his sword and turned back to the fight alongside him. Karim was still duelling with the same Roman, exchanging sword blows that rang sharply. But the legionary was one against two and even as he parried another thrust, Ajax hooked his blade around the edge of the shield and ran it through his enemy's arm, severing muscles. The shield slipped from the Roman's grasp and he instinctively recoiled a pace, out of range of their swords. At once two arrows slammed into him from above, piercing his sword arm in two places. The Roman howled in agony and staggered to the side and fell off the ramp, tumbling on to the bodies of those below.

The attackers at the bottom of the ramp hesitated, then one was struck in the face by another arrow and jerked up to his full height and trembled wildly for an instant before he dropped to the ground. There were more bodies on either side of the leading century as well as a handful of Arabs who had been shot down from the wall of the temple.

'Fall back!' a voice cried out. 'Fall back!'

There was a brief hesitation, then Ajax saw the legionaries begin to shuffle away from the end of the surviving ramp. More of them took up the cry and the leading century began to break up as it fell back towards the breach.
