The story of the Claudian Conquest of Britain was only parly recorded by ancient historians. Tacitus Annals breaks off at the death of Tiberius, while the narrative of Cassius Dio survives only as a collection of elected pieces. Much of the missing knowledge has been recaptured by archaelogical research. As a result we have a better understanding of the tribal society which then existed in Britain and this can help us to appreciate the courses of military action open to Plautius, the commanding Roman general. Peddie argues that organization and supply problems of the Roman task force dictated Roman tactics. He discusses what these may have been, examines the reasons for a seemingly isolated foray into the West Country, and suggests that the guerrilla campaign of AD 43-52 denied the Romans their hope of a speedy conquest.
