Figulus craned his neck round and squinted through a small gap in the willow-weave that formed the wall of the byre. Beyond the wall the rest of the enemy’s camp stretched out across the island: hundreds of round huts, enclosed by a low palisade. There was only one approach to the camp, along a slender causeway that crossed the shallow waters surrounding the island. The causeway was defended by two formidable redoubts that projected from the island, either side of the main gate, which itself was made of thick timbers of oak. Inside the gate the survivors of Caratacus’ army rested and licked their wounds, while they waited for their commander to decide what to do next.

When the small column of Roman prisoners had been led into the camp a large crowd of warriors and a few women and children had turned out to pour scorn and ridicule on the half-starved and filthy representatives of their vaunted enemy. While keeping his head protected as best he could from the shower of mud, shit and stones, Cato had looked round the camp with a professional interest. The warriors had kept their equipment clean and many still sweated from the training they had been doing before the prisoners had arrived. Cato had expected them to be demoralised and beaten after the almost complete disaster at the crossing of the Tamesis fifteen days before. But these men were clearly fit and eager to return to the fight.

The prisoners had been paraded round the camp and forced to suffer the usual indignities of capture before being led to this byre, where they had remained for three days, fed on scraps and tied up around the wrists and ankles. The existing stench of the small space had been made worse by the urine, shit, vomit and sweat of the prisoners, unable to move far from their position, without disturbing their comrades bound on either side. By day the sun beat down on them, cooking the thick fetid air that filled the byre so that every breath made Cato and his men feel nauseous. Outside, the Britons trained hard, with the monotonous clash and clatter of weapons, punctuated by the grunts and war cries of men determined to fight on against the legions with every fibre of their being.

‘Not much chance of finding a way out through that lot,’ Figulus said, as he turned round and leaned back against the wicker wall. The optio reached down and tried to ease the leather collar around his ankle into a more comfortable angle. ‘Even if we could get out of these.’
