‘On foot!’ Vespasian shouted over his shoulder to the eagle-bearer, and swung himself from the back of his horse. At once they were spotted by the defenders above them, and an instant later Vespasian’s horse screeched as an arrow whacked into its flank. It reared up, front legs flailing, before scrabbling round to tear back down the ramp. More arrows and slingshot thudded home around the legate. He looked round and snatched a shield from the ground where it had fallen beside its dead owner. The eagle-bearer found another. Both of them pushed forward into the tightly packed ranks ahead.

‘Make way! Make way there!’ Vespasian called.

The legionaries parted at the sound of his voice, some with looks of blank astonishment.

‘What the fuck is he doing up here?’ an awestruck youngster wondered.

‘Didn’t think you were getting the enemy all to yourself, did you, son?’ Vespasian shouted as he passed by. ‘Come on, lads, one last push, then we ‘11 put paid to those bastards!’

A ragged cheer rippled out from the men as Vespasian and the eagle-bearer made their way up towards the gate, arrows and slingshot rattling off their shields. When he reached the flat ground before the fortified timber gate, Vespasian tried to hide his despair at the scene before him. Most of the engineers were dead, heaped round their ladders and to the side of the battering ram. The ram was now manned by legionaries who had had to lay down their shields to take up their position on the thick iron capped shaft of oak. Even as he watched, another man fell, shot through the gap between his helmet and his mail vest. The senior centurion thrust a replacement forward, but the legionary hesitated, looking anxiously at the savage faces screaming at him above the gate.

Vespasian ran forward. ‘Out of my way, son!’

He dropped his shield and grabbed the rope handle, joining the rhythmic swing of the other men on the ram. As it smashed into the gate, with a shattering crash, Vespasian could see that the big timbers were starting to give way.

‘Come on, men!’ he shouted to the others along the ram. ‘We’re not being paid by the bloody hour!’

As soon as the Durotriges saw the legate they let out a great roar of defiance and turned their weapons on the enemy commander, and the man bearing the dreaded symbol of the eagle. The men of the First Cohort responded with a deafening cheer and renewed effort, hurling up their remaining javelins into the marred ranks of the Durotriges. Others snatched at the slingshots lying on the ground to hurl them at the defenders.
