The various tribes of Britain possessed valor without conduct, and the love of freedom without the spirit of union. They took up arms with savage fierceness; they laid them down, or turned them against each other, with wild inconsistency; and while they fought singly, they were successively subdued. Neither the fortitude of Caractacus, nor the despair of Boadicea, nor the fanaticism of the Druids, could avert the slavery of their country, or resist the steady progress of the Imperial generals, who maintained the national glory, when the throne was disgraced by the weakest, or the most vicious of mankind. At the very time when Domitian, confined to his palace, felt the terrors which he inspired, his legions, under the command of the virtuous Agricola, defeated the collected force of the Caledonians, at the foot of the Grampian Hills; and his fleets, venturing to explore an unknown and dangerous navigation, displayed the Roman arms round every part of the island.
