Conquer
Despite the fact that Caesar’s invasion of Britain wasn’t successful, the Romans eventually had a successful attack against the Britons after Caesar’s murder in the first century A.D. This pushed the Britons on the island west to Wales and Cornwall and north to Scotland. As it turns out, the Romans actually built Hadrian’s Wall near what is now the border between England and Scotland, in 120 A.D. The wall was meant to protect the Roman settlers from the Celts who had fled north.
