Macro looked up. More slaves were pouring from under the trees.

He could not estimate their strength, but they clearly outnumbered the men in Macro's column. However, the auxiliaries were trained fighters, and well armed. As Macro glanced round, he saw that his men were holding their own, cutting down the slaves as they came on in a disorganised rush. A sudden snarl snapped Macro's attention back to his front as a slave leaped towards him, swinging a me at -

cleaver. He just had time to throw his shield up as the heavy blade slammed into the edge, cutting through the bronze trim and splintering the wood beneath, where it stuck fast.

'My turn!' Macro snarled, slashing at the side of the man's head, and the blade jarred as it bit through skin and skull with a wet crack.

As the man dropped to his knees with a stunned expression, Macro withdrew his sword and knocked the cleaver free with the guard. Just then he felt something grasp his ankle and looked down to see that the first man had dragged himself towards his boot and, having grabbed it, was preparing to sink his teeth into Macro's calf.

'Don't you dare!' Macro kicked the hand free and stamped on the man's wrist with his nailed boot. Then he swung the lower edge of the shield at the slave's head, knocking the stricken man out.' When I put you down, you stay down!'

Macro edged along the track, keeping pace with the leading wagon. He glanced to his left and saw that some of his men were too intent on the fight to realise that the wagons were continuing forward.

'Keep moving!' Macro yelled. 'Protect the bloody wagons!'

Even though they were poorly armed and being hacked down in droves, the slaves continued their ferocious assault, as if they had no fear of death. Macro saw one spitted by a spear as he hurled himself at the auxiliaries. The bloodied tip of the spear exploded through the back of his tunic and the slave heaved himself along the shaft as he clawed at the auxiliary's head. The soldier released his grip on the spear and snatched out his sword, thrusting it into the slave's throat.

With a bloody gurgle of rage the slave flailed at his opponent, spattering the auxiliary with blood before his strength gave out and he slumped to his knees, still pierced through by the spear. The auxiliary backed away, hastily looking round to make sure that he was keeping a loose formation alongside his comrades as they paced along the road, doing their best to stay close to the wagons. The ground on either side was strewn with bodies, and still the slaves came on. Macro struck down a toothless man, old enough to be his father, and the man cursed him as he died.

A hand grasped Macro's shoulder and he spun round, ready to strike, until he saw Atticus and just managed to stay his sword in time.

'Give me a weapon,' Atticus pleaded. 'Before they tear me to pieces!'

Macro looked round and saw a pitchfork lying beside the body of a slave, no more than a boy. 'There! Take it.'

Atticus snatched the pitchfork up and grasped the shaft firmly as he lowered the prongs at a thin man racing towards him with a nailed club. The slave swung the club in a vicious arc, aiming at Atticus's head. The latter ducked the blow and then thrust his prongs into the slave's stomach, and with a grunt of brute strength carried the wiry slave up off the ground. The slave screamed as his weight carried him further down the sharp iron spikes that impaled him. Atticus twisted the shaft to one side and the slave crashed to the ground. Placing a boot on the man's chest he wrenched the prongs free and immediately went into a crouch as he looked round for another threat.

'Good job,' Macro said grudgingly.

The leading wagon rumbled out of the wood on to clear ground and continued towards the ruined villa, the driver cracking his whip over the heads of the horses and mules as he urged them on. Ahead of him, a couple of auxiliaries were forced to scramble to the side of the track before they were run down. Macro ground his teeth furiously as he trotted after the wagon.

'Not so bloody fast, you fool!'

The driver carried on heedlessly, and the others followed his example as the wagons emerged from the wood, leaving the auxiliaries and volunteers scrambling to keep up as they tried to fight off the slaves swarming round the column like angry wasps. One of Macro's men, at the rear of the last wagon, stumbled -and fell, sprawling across the gravelled track. At once several slaves leaped on him with bloodthirsty howls of triumph and hacked and stabbed at him as he struggled on the ground. He let out a piercing shriek, before it was savagely cut off as axe blows rained down on his head.

Macro could see the danger clearly enough. If the men in the column could not stay together then they would be overwhelmed and butchered one by one. He had to slow the leading wagon. With a curse he released his grip of the shield handle and tossed it to one side so that it would not weigh him down. Fortunately there had been no time to find any greaves for his legs, and the scale armour was not heavy enough to stop him breaking into a run. He sheathed his sword and ran as fast as he could to overhaul the leading wagon, passing the heavy rear wheels. As it lurched over a bump, a jar of olive oil tipped over the side, narrowly missing Macro, and shattered on the stony track. He leaped over the shards of pottery, and as he drew level with the driver, grasped the side of the bench and launched himself up on to the foot rail. The driver glanced down in panic, before he saw it was one of his own side, and then cracked his whip again.

Macro did not waste time with any more words and struggled to his feet, driving his fist into the man's stomach so that he doubled over with a grunt, dropping the whip and traces as he slumped across the bench, gasping for breath. Macro snatched the traces up and pulled them sharply, dragging back on the horses' bridles.

'Whoa! Whoa there!'

With frightened whinnies the horses drew up and the slight incline of the track slowed the wagon at once. Macro settled them on a steady pace and then glanced round. He saw Atticus close by, still brandishing his pitchfork as he kept two slaves at bay. Now that the column was in the open, Macro had a far better view of his situation. Scattered across the field on either side were two or three hundred slaves. After witnessing the fall of so many of their comrades in the first moments of the attack, the rest were now more wary, and they hung back from the column, waiting to pounce on any stragglers, or charge into any gaps between the wagons and the men defending them.

'Atticus!' Macro shouted to him. 'Over here!'

Atticus thrust at the slaves nearest to him and trotted warily up along the side of the leading wagon. Macro leaned towards him, clasping the man's hand and hauling him up on to the driver's bench.

'Here, take the traces. Keep the speed down so that the rest of the wagons and the men can keep up. Is that clear?'

Atticus nodded, still breathing raggedly from his exertions. He took the traces in one hand, and kept a tight grip on the shaft of his weapon with the other. Macro waited a moment to be sure that he had the right pace, and then jumped clear of the wagon, landing heavily. At once he straightened up and drew his sword again.

'Twelfth Hispania! Stay with the wagons!'

The auxiliaries and those volunteers who had snatched up weapons from the dead and injured formed a loose cordon around the wagons as the column continued up the track at a measured pace.

The slaves stayed with them, but kept more than a spear's length away, to one side of the wagons. Some had begun to snatch up stones and small rocks from the ground, and hurled them at the Roman soldiers. The uneven rattle and thud of the makeshift missiles accompanied the column all the way to the remains of the villa.
