The Battle of Caer Caradoc was the final battle in Caratacus's resistance to Roman rule. Fought in 50, the Romans defeated the Britons and thus secured the southern areas of the province of Britannia. Caratacus chose a battlefield in hilly country, placing the Britons on the higher ground. His forces were probably primarily made up of warriors from the Ordovices though there may have been some Silures as well. This position made both approach and retreat difficult for the Romans, and comparatively easy for his own forces. Where the slope was shallow, he built rough stone ramparts, and placed armed men in front of them. In front of them was a river, probably the Severn or Teme.
