The Silures waged effective warfare against the Roman forces. Ostorius died with this tribe still unconquered; after his death they won a victory over the Roman Second Augusta Legion, Legio II Augusta. There were no more attempts to extend Roman control in Wales until the governorship of Caius Suetonius Paulinus, who attacked further north and captured the island of Anglesey in 60 or 61 AD. However he was forced to stop the offensive to meet the threat from the rebellion of Boudica.
