The rebels destroyed the city and slaughtered its population. Archaeologists have found layers of ash in the site of the city, suggesting that Boudica ordered her rebel army to burn the city to the ground. A relief army consisting of the Legio IX Hispana led by Quintus Petillius Cerialis attempted to rescue the besieged citizens, but was destroyed outside of the town. After the Romans under governor Gaius Suetonius Paullinus finally defeated the uprising, the Procurator of the province moved his seat to the newly established commercial settlement of Londinium (London).
