From the moment the bolt-throwers ceased firing on the palisade, the First Cohort would fall under a rain of arrows, slingshot and boulders. Due to the twists and turns in the approach ramps, one or other of their flanks would be exposed to enemy fire before they even reached the main entrance. Then they would have to endure more of the same while they attempted to breach the gate. Only then would they be able to close with the enemy. It was only natural that the men who had endured so much punishment would want to exact bloody retribution once the Durotriges were within swords’ length. Vespasian had therefore personally briefed each officer in the cohort to look out for Cato and his party and that every effort must be made to take prisoners. He told them he needed live slaves if he was ever going to be able to afford to renovate his house on the Quirinal Hill, back in Rome. They had laughed at that, as he’d known they would, and Vespasian hoped it would be enough to prevent Cato and his men being slaughtered out of hand when the legionaries eventually burst onto the plateau.

‘All ready, sir,’ Tribune Plinius reported.

‘Very well.’ Vespasian saluted and looked over his shoulder.

The horizon away to the east was becoming noticeably lighter. He turned back and regarded the looming immenseness of the hill fort. The wicker man towered above the palisade, the auburn twists of cane and branch slowly becoming visible as dawn strengthened and banished the monochrome shades of the night. The crews on the artillery platform stood still, watching the legate, waiting for the order to open fire. Vespasian had managed to muster over a hundred serviceable bolt-throwers, and each one now sat ready for winding back the torsion arms. The iron-headed bolts were already set in each channel, their dark-flanged heads pointing up at the defences surrounding the main gate. The first rays of the sun caught the shining bronze helmets of the Durotriges lining the palisade, watched by the legionaries in the cool gloom below. Gradually the glow flowed down the slopes of the ramparts.

Vespasian nodded to Plinius.

‘Artillery!’ Plinius roared through cupped hands. ‘Make ready!’

The dawn air was filled with the sound of clanking levers and straining men as the torsion arms were wound back and the bolt ropes locked down against the projectiles. As the last crew finished, the sound died away and a peculiar stillness fell over the scene.

‘Open fire!’ Plinius shouted.
