<P> The British were pushed back to the Thames . They were pursued by the Romans across the river causing some Roman losses in the marshes of Essex . Whether the Romans made use of an existing bridge for this purpose or built a temporary one is uncertain . At least one division of auxiliary Batavian troops swam across the river as a separate force . </P> <P> Togodumnus died shortly after the battle on the Thames . Plautius halted and sent word for Claudius to join him for the final push . Cassius Dio presents this as Plautius needing the emperor's assistance to defeat the resurgent British, who were determined to avenge Togodumnus . However, Claudius was no military man . Claudius's arch says he received the surrender of eleven kings without any loss, and Suetonius' The Twelve Caesars says that Claudius received the surrender of the Britons without battle or bloodshed . It is likely that the Catuvellauni were already as good as beaten, allowing the emperor to appear as conqueror on the final march on Camulodunum . Cassius Dio relates that he brought war elephants and heavy armaments which would have overawed any remaining native resistance . Eleven tribes of South East Britain surrendered to Claudius and the Romans prepared to move further west and north . The Romans established their new capital at Camulodunum and Claudius returned to Rome to celebrate his victory . Caratacus escaped and would continue the resistance further west . </P> <P> Vespasian took a force westwards subduing tribes and capturing oppida as he went, going at least as far as Exeter, which would appear to have become an early base for Leg. II Augusta . Legio IX Hispana was sent north towards Lincoln (Latin: Lindum Colonia) and within four years of the invasion it is likely that an area south of a line from the Humber to the Severn Estuary was under Roman control . That this line is followed by the Roman road of the Fosse Way has led many historians to debate the route's role as a convenient frontier during the early occupation . It is more likely that the border between Roman and Iron Age Britain was less direct and more mutable during this period . </P> <P> Late in 47 the new governor of Britain, Publius Ostorius Scapula, began a campaign against the tribes of modern - day Wales, and the Cheshire Gap . The Silures of southeast Wales caused considerable problems to Ostorius and fiercely defended the Welsh border country . Caratacus himself was defeated in the Battle of Caer Caradoc and fled to the Roman client tribe of the Brigantes who occupied the Pennines . Their queen, Cartimandua was unable or unwilling to protect him however given her own truce with the Romans and handed him over to the invaders . Ostorius died and was replaced by Aulus Didius Gallus who brought the Welsh borders under control but did not move further north or west, probably because Claudius was keen to avoid what he considered a difficult and drawn - out war for little material gain in the mountainous terrain of upland Britain . When Nero became emperor in 54, he seems to have decided to continue the invasion and appointed Quintus Veranius as governor, a man experienced in dealing with the troublesome hill tribes of Anatolia . Veranius and his successor Gaius Suetonius Paulinus mounted a successful campaign across Wales, famously destroying the druidical centre at Mona or Anglesey in 60 at what historians later called the Menai Massacre . Final occupation of Wales was postponed however when the rebellion of Boudica forced the Romans to return to the south east . The Silures were not finally conquered until circa 76 when Sextus Julius Frontinus' long campaign against them began to have success . </P>
