The imperial party had been dining under a large open-sided tent and the last notes of music from the flutes and harps of a Greek ensemble died away as Claudius led his family and advisers past the other guests who had hurriedly risen to their feet. They emerged into the bright sunshine and the men of Burrus’s cohort snapped smartly to attention, javelins and shields held firmly in each hand. Three centuries stood lined up either side of the short route from the banqueting tent to the garlanded entrance of the pavilion, beyond which a wide staircase led up to the viewing platform. The German bodyguards were already in place, positioned around the imperial box where Claudius and his family would sit on cushioned chairs.

The Sixth Century, still enjoying the particular gratitude of Claudius, had the honour of guarding the outside of the pavilion while the rest of the cohort was to be held back a short distance in case they were needed to assist the auxiliaries guarding the food stockpile and prisoner pens.

Once the Emperor and his entourage had entered the pavilion, Burrus marched the other five centuries away and Centurion Tigellinus began to dispose his men around the perimeter of the pavilion. Cato and Macro were posted to a shaded spot just below the reviewing stand.

‘Here we go,’ said Macro, gesturing towards the prisoner pens. ‘The show’s about to start.’

Cato turned his head and saw the first batch of prisoners being led out through one of the gates. They were herded down to the ships by the shore and there half of them were issued helmets, shields, swords and armour from the back of a wagon. The other half were directed up the wooden ramp to the first ship’s deck and then ordered below to man the oars.

‘Look at that kit,’ Macro remarked. ‘They must have emptied the Temple of Mars for that lot. Celt, Greek, Numidian. Some of that stuff must date back to before the civil war.’
