The story begins in 60AD when a brutal assault on Boudicca and her daughters turned the queen into a rebel leader. It was perfect timing - much of the Roman army was in Anglesey, carrying out a slaughter of the Druids. Boudicca marched her entire tribe and their neighbours on the centre of Roman rule, Colchester, which was torched. London was next; it, too, burnt to the ground. The final confrontation between the two armies took place somewhere north of St Albans. The exact location is a matter of debate but Peter and Dan investigate the most recent suggestion: an area near the village of Paulerspury. Peter uses the remarkable computer graphics to show the Romans’ predicament – outnumbered 10 to one, it was only their discipline, tactics and the cunning choice of battlefield by Suetonius Paulinus that swung the battle in their favour.
