It was probably in the same year in which Claudius succeeded to the empire, or it may have been a year later, that old King Cunobelinus died in Britain and was succeeded by his two sons, Caratacus[7] and Togodumnus. There was, as usual, an exiled prince (whose name was Bericus) claiming Roman assistance for his restoration to his country, but whether he was one of the sons of Cunobelinus or not, neither history nor the coins inform us. The petition of the exiled Bericus was granted by Claudius, and an expedition was resolved on, nominally for his restoration (from this point onwards his name disappears from history), in reality for the conquest of Britain (A.D. 43). The command of the expedition was entrusted to Aulus Plautius, a senator of high rank--he had been consul fourteen years before with the Emperor Tiberius--and was possibly a kinsman of Claudius by marriage. Under his orders marched four legions[8]:-- The Second: Augusta. The Ninth: Hispana. The Fourteenth: Gemina Martia; and The Twentieth: Valeria Victrix. All of these but the Ninth were withdrawn from service in Germany, and that legion came from Pannonia, in modern language Hungary west of the Danube. The Second and the Twentieth legions found a permanent home in our island; the Ninth, a grave; the Fourteenth after a brilliant career was withdrawn to Italy after about twenty-five years of British service. We have no exact statement of the number of the army of Plautius. The legions, if at their full complement, should stand for 20,000 men: the cavalry and cohorts of the allies should at least double that number. We are probably not far wrong in putting the invading force at 50,000, but the difficulty of forming an exact estimate is shown by the divergence between the calculations of two such experts as Mommsen and Hübner, the former of whom reckons the total at 40,000, and the latter at 70,000 men.
