[Sidenote: A.D. 43]
This gave occasion to the Emperor Claudius, ninety-seven years after the first expedition of Caesar, to invade Britain in person, and with a great army. But he, having rather surveyed than conducted the war, left in a short time the management of it to his legate, Plautius, who subdued without much difficulty those countries which lay to the southward of the Thames, the best cultivated and most accessible parts of the island. But the inhabitants of the rough inland countries, the people called Cattivellauni, made a more strenuous opposition. They were under the command of Caractacus, a chief of great and just renown amongst all the British nations. This leader wisely adjusted his conduct of the war to the circumstances of his savage subjects and his rude country. Plautius obtained no decisive advantages over him. He opposed Ostorius Scapula, who succeeded that general, with the same bravery, but with unequal success; for he was, after various turns of fortune, obliged to abandon his dominions, which Ostorius at length subdued and disarmed.
This bulwark of the British freedom being overturned, Ostorius was not afraid to enlarge his plan. Not content with disarming the enemies of Rome, he proceeded to the same extremities with those nations who had been always quiet, and who, under the name of an alliance, lay ripening for subjection. This fierce people, who looked upon their arms as their only valuable possessions, refused to submit to terms as severe as the most absolute conquest could impose.

The frontiers of this acquisition, which extended along the rivers Severn and Nen, he secured by a chain of forts and stations; the inland parts he quieted by the settlement of colonies of his veteran troops at Maldon and Verulam: and such was the beginning of those establishments which
