As the legionaries scaled the earth ramps to either side of the gate Macro saw Cato and caught his arm. 'Optio! I want you and six men ready with that locking bar. When I give the word, you get it into the gate braces as quick as you can. Understand?'

'Yes, sir.' Cato answered, staring at a crimson gash on the centurion's sword arm.

'Good. Then see to it.'

Then he was gone, thrusting his way back through the lines defending the gateway, shouting encouragement to his men. Cato quickly stirred and saw that the nearest men were watching him, waiting.

'Right!' He tried to sound firm. 'You heard him. Sheath swords and down shields.'

Astonishingly – to Cato at least – they reacted to the order and, unencumbered by the large heavy shields, they reached down and took a firm hold of the rough-hewn locking bar. Cato leaned his shield against the wall of a hut, then he bent and grasped the front of the bar.

'Ready? Lift!'

Cato slowly straightened, gasping with effort as he strained to raise the bar on to his shoulder where it rested uncomfortably. 'Right then,' he said through gritted teeth. 'Over to the gate, easy now!'

They struggled forward, stepping carefully over the prostrate forms of Romans and Germans, and then stood waiting to one side of the gate where the fight seemed to be going the Germans' way. The thin ranks of legionaries were slowly being forced to give ground. With his height Cato could see the Germans beyond, snarling with rage, throwing themselves forward on the Romans.

Macro shouted. 'More fire from the wall there! Use everything you've got!'

The soldiers above desperately rained down the last of their javelins, together with rocks and stones torn from the nearest huts, on to the heads of the helpless Germans. Instinctively those at the front drew back from the gate, away from the slaughter.

'Back!' Macro turned and shoved the nearest legionaries back through the gate. The remaining Romans hurriedly withdrew, presenting their shields to the enemy. The last men through grabbed the edges of the gate and frantically swung the heavy timbers towards the Germans. Outside there was a howl as the enemy realised what was happening and they rushed forward again, regardless of the stones being hurled down from the walls above. At their head raced a tall warrior, blind rage and hatred etched on to his broad features. As the gates swung out to meet him he lunged for the nearest Roman with his spear.

'No, you fucking don't!' Macro swung his sword down on the head of the spear, knocking it to the ground. Unable to check himself, the German tumbled into the rapidly closing gap and Macro head-butted him, flattening his nose with a sickening crunch. As the German howled, Macro kicked him free of the gate. 'Piss off, you bugger!'

The gates closed with a grinding thud and – before the order could be given – Cato and his men quickly heaved the bar up, over and into the holding brackets where it dropped solidly into place. An instant later the gates suddenly swung in against the bar, which groaned against the strain. Macro watched for a moment to make sure that they were secure and then, posting a guard at the base of the gates, he ordered the remains of the century up on to the wall.

The village wall was a miserable affair, erected mainly to ward off marauding war-bands from the wilderness beyond the Rhine. The dirt from the ditch surrounding the village had been heaped up to form an interior rampart, faced with turf to hold the soil in place. A narrow walkway, surfaced with a corduroy of logs, ran along the top of the wall beside a chest-high palisade of sharpened stakes, chest-high to a normal man but neck-high to the stocky Macro, who rose on his toes to best view the scene in front of the gate.

A seething mass of Germans stretched out in front of and to the sides of the village, like two arms encircling the Romans trapped within. Immediately below Macro, the Germans were being driven from the gate by a fresh fusillade of stones and a respectful gap, littered with dead and wounded, formed in front of the thick timbers. Further back Macro could see that faggots were already being bundled together from a stock of firewood the villagers had left beyond their walls where it would not be a fire risk. Once those faggots were ready, it would only be a matter of time before the ditch was filled and an approach to the wall was completed. At least the century had bought some time for the rest of the cohort. Macro turned to look for any sign of the other centuries. Dull cries and the faint clash of weapons sounded from elsewhere in the village and, from his slightly elevated position, Macro could see other legionaries stretched out around the wall. The village was secure then. Good. Time to make a report.

Looking down at the carpet of bodies strewn over the street leading up to the gate Macro estimated that almost a fifth of his men were dead, or badly wounded. He glanced up and caught the eye of young Cato, who instantly flashed his gaze over the wall with an expression of rapt attention.

'Cato! Keep your fucking head down, unless you want some German to use it for target practice!'

'Yes, sir.'

'Come here. Job for you.'

Hunched down below the palisade, Macro removed his helmet and wiped his brow with his uninjured arm. As he prepared to give the details of the report to Cato, he ran a finger along a dent across the top of his helmet.

'Wouldn't know anything about that I suppose?'

Cato blushed silently.

'I guessed not. But if anyone tries to spit me like that again I'll have the bastard's hide. Now then I want you to find the tribune. Find him as quick as you can and you tell him we're holding this gate. Tell him I've got about seventy effectives left and then ask him for orders. Understand?'

Cato nodded.

'Get going then!' Macro slapped him on the helmet.

The centurion watched Cato run down the ramp to the street and quickly pick his way over the dead and wounded. As he replaced his helmet, Macro made a mental note to have a word with Bestia if they ever got out of this mess. That boy definitely needed some more javelin practice. He sighed and cautiously peered over the palisade to see how the Germans were progressing with the faggots.

– =OO=OOO=OO-=

Cato's boots pounded down the street as he ran back the way the century had come only a little while earlier. Alone, he felt vulnerable and he glanced nervously from side to side as he hurried between the squalid ranks of German huts and buildings. But he saw no-one until he had almost reached the square at the heart of the village. There he ran into a Roman picket guarding the approach. The two legionaries hefted their javelins anxiously at his approach, looking beyond him, but were relieved when Cato drew up, breathing heavily.

'Where's the tribune?'

'What's happening, Optio?'

'Nothing… need to find the tribune… message for him.'

One of the legionaries gestured over his shoulder. 'Back there, by the chief's hut. What gives at the other gate?'

'It's being held,' Cato called over his shoulder as he ran past.

When he emerged from the narrow street into the square Cato halted in surprise. Hundreds of Germans of all ages were milling around in the centre. Then he saw that they were being herded together by scores of legionaries who pushed with their shields and prodded with javelins to steer their charges into a compact group for easy guarding. Some were still being driven in from the surrounding streets as Cato pushed his way through to the chief's hut where Vitellius was giving orders to a centurion.

'… and if they put up any struggle, or try anything on, kill them all.'

'Kill them?' The centurion looked uncertainly at the villagers, many of whom were wailing loudly. 'Kill them all?'

'That's what I said,' Vitellius snapped, and then sneered. 'Or haven't you got the stomach for it?'
