Book excerpt: The Roman Conquests series seeks to explain when and how the Romans were able to conquer a vast empire stretching from the foothills of the Scottish Highlands to the Sahara Desert, from the Atlantic to the Persian Gulf. How did their armies adapt to and overcome the challenges of widely varied enemies and terrain? In this volume, Dr Simon Elliott draws on the latest research and archaeological evidence to present a new narrative of the conquest (never completed) of Britain. From Julius Caesar’s initial incursions in 55 and 54 BC, through the Claudian invasion of 43 AD and the campaigns of expansion and pacification thereafter, he analyses the Roman army in action. The weapons, equipment, organization, leadership, strategy and tactics of the legions and their British foes are described and analysed. The ferocity of the resistance was such that the island was never wholly subdued and required a disproportionate military presence for the duration of its time as a Roman province.
