ROME RETREATS

But the period was now come, when that enormous fabric of the Roman empire, which had diffused slavery and oppression, together with peace and civility, over so considerable a part of the globe, was approaching towards its final dissolution. Italy, and the centre of the empire, removed during so many ages from all concern in the wars, had entirely lost the military spirit, and were peopled by an enervated race, equally disposed to submit to a foreign yoke, or to the tyranny of their own rulers. The emperors found themselves obliged to recruit their legions from the frontier provinces, where the genius of war, though languishing, was not totally extinct; and these mercenary forces, careless of laws and civil institutions, established a military government no less dangerous to the sovereign than to the people.

The further progress of the same disorders introduced the bordering barbarians into the service of the Romans; and those fierce nations, having now added discipline to their native bravery, could no longer be restrained by the impotent policy of the emperors, who were accustomed to employ one in the destruction of the others. Sensible of their own force, and allured by the prospect of so rich a prize, the northern barbarians, in the reign of Arcadius and Honorius, assailed at once all the frontiers of the Roman empire; and having first satiated their avidity by plunder, began to think of fixing a settlement in the wasted provinces.

The more distant barbarians, who occupied the deserted habitations of the former, advanced in their acquisitions, and pressed with their incumbent weight the Roman state, already unequal to the load which it sustained. Instead of arming the people in their own defence, the emperors recalled all the distant legions, in whom alone they could repose confidence; and collected the whole military force for the defence of the capital and centre of the empire. The necessity of self-preservation had superseded the ambition of power; and the ancient point of honor, never to contract the limits of the empire, could no longer be attended to in this desperate extremity.

Britain by its situation was removed from the fury of these barbarous incursions; and being also a remote province, not much valued by the Romans, the legions which defended it were carried over to the protection of Italy and Gaul. But that province, though secured by the sea against the inroads of the greater tribes of barbarians, found enemies on its frontiers, who took advantage of its present defenceless situation. The Picts and Scots, who dwelt in the northern parts, beyond the wall of Antoninus, made incursions upon their peaceable and effeminate neighbors; and besides the temporary depredations which they committed, these combined nations threatened the whole province with subjection, or, what the inhabitants more dreaded, with plunder and devastation,

The Picts seem to have been a tribe of the native British race, who, having been chased into the northern parts by the conquests of Agricola, had there intermingled with the ancient inhabitants: the Scots were derived from the same Celtic origin, had first been established in Ireland, had migrated to the north-west coasts of this island, and had long been accustomed, as well from their old as their new seats, to infest the Roman province by piracy and rapine.

These tribes finding their more opulent neighbors exposed to invasion, soon broke over the Roman wall, no longer defended by the Roman arms; and, though a contemptible enemy in themselves, met with no resistance from the unwarlike inhabitants. The Britons, accustomed to have recourse to the emperors for defence as well as government, made supplications to Rome: and one legion was sent over for their protection. This force was an overmatch for the barbarians, repelled their invasion, touted them in every engagement, and having chased them into their ancient limits, returned in triumph to the defence of the southern provinces of the empire. Their retreat brought on a new invasion of the enemy.

The Britons made again an application to Rome, and again obtained the assistance of a legion, which proved effectual for their relief: but the Romans, reduced to extremities at home, and fatigued with those distant expeditions, informed the Britons that they must no longer look to them for succor, exhorted them to arm in their own defence, and urged, that, as they were now their own masters, it became them to protect by their valor that independence which their ancient lords had conferred upon them. That they might leave the island with the better grace, the Romans assisted them in erecting anew the wall of Severus, which was built entirely of stone, and which the Britons had not at that time artificers skilful enough to repair. And having done this last good office to the inhabitants, they bade a final adieu to Britain, about the year 448, after being masters of the more considerable part of it during the course of near four centuries.
