The History of the Decline and Fall of the Roman Empire - Edward Gibbon [277]
[Footnote 29: When Mamertinus pronounced his first panegyric, the naval preparations of Maximian were completed; and the orator presaged an assured victory. His silence in the second panegyric might alone inform us that the expedition had not succeeded.]
[Footnote 30: Aurelius Victor, Eutropius, and the medals, (Pax Augg.) inform us of this temporary reconciliation; though I will not presume (as Dr. Stukely has done, Medallic History of Carausius, p. 86, &c) to insert the identical articles of the treaty.]
Before the preparations were finished, Constantius received the intelligence of the tyrant's death, and it was considered as a sure presage of the approaching victory. The servants of Carausius imitated the example of treason which he had given. He was murdered by his first minister, Allectus, and the assassin succeeded to his power and to his danger. But he possessed not equal abilities either to exercise the one or to repel the other.
He beheld, with anxious terror, the opposite shores of the continent already filled with arms, with troops, and with vessels; for Constantius had very prudently divided his forces, that he might likewise divide the attention and resistance of the enemy. The attack was at length made by the principal squadron, which, under the command of the praefect Asclepiodatus, an officer of distinguished merit, had been assembled in the north of the Seine. So imperfect in those times was the art of navigation, that orators have celebrated the daring courage of the Romans, who ventured to set sail with a side-wind, and on a stormy day. The weather proved favorable to their enterprise. Under the cover of a thick fog, they escaped the fleet of Allectus, which had been stationed off the Isle of Wight to receive them, landed in safety on some part of the western coast, and convinced the Britons, that a superiority of naval strength will not always protect their country from a foreign invasion. Asclepiodatus had no sooner disembarked the imperial troops, then he set fire to his ships; and, as the expedition proved fortunate, his heroic conduct was universally admired. The usurper had posted himself near London, to expect the formidable attack of Constantius, who commanded in person the fleet of Boulogne; but the descent of a new enemy required his immediate presence in the West. He performed this long march in so precipitate a manner, that he encountered the whole force of the praefect with a small body of harassed and disheartened troops. The engagement was soon terminated by the total defeat and death of Allectus; a single battle, as it has often happened, decided the fate of this great island; and when Constantius landed on the shores of Kent, he found them covered with obedient subjects. Their acclamations were loud and unanimous; and the virtues of the conqueror may induce us to believe, that they sincerely rejoiced in a revolution, which, after a separation of ten years, restored Britain to the body of the Roman empire. ^31

Part II.
Britain had none but domestic enemies to dread; and as long as the governors preserved their fidelity, and the troops their discipline, the incursions of the naked savages of Scotland or Ireland could never materially affect the safety of the province.
The peace of the continent, and the defence of the principal rivers which bounded the empire, were objects of far greater difficulty and importance. The policy of Diocletian, which inspired the councils of his associates, provided for the public tranquility, by encouraging a spirit of dissension among the barbarians, and by strengthening the fortifications of the Roman limit. In the East he fixed a line of camps from Egypt to the Persian dominions, and for every camp, he instituted an adequate number of stationary troops,
