Then new enemies arose. They were the Saxons, a fierce, sea-faring people from the countries to the North of the Rhine, the great river of Germany on the banks of which the best grapes grow to make the German wine. They began to come, in pirate ships, to the sea-coast of Gaul and Britain, and to plunder them. They were repulsed by Carausius, a native either of Belgium or of Britain, who was appointed by the Romans to the command, and under whom the Britons first began to fight upon the sea. But, after this time, they renewed their ravages. A few years more, and the Scots (which was then the name for the people of Ireland), and the Picts, a northern people, began to make frequent plundering incursions into the South of Britain. All these attacks were repeated, at intervals, during two hundred years, and through a long succession of Roman Emperors and chiefs; during all which length of time, the Britons rose against the Romans, over and over again. At last, in the days of the Roman Honorius, when the Roman power all over the world was fast declining, and when Rome wanted all her soldiers at home, the Romans abandoned all hope of conquering Britain, and went away. And still, at last, as at first, the Britons rose against them, in their old brave manner; for, a very little while before, they had turned away the Roman magistrates, and declared themselves an independent people. Five hundred years had passed, since Julius Cæsar’s first invasion of the Island, when the Romans departed from it for ever. In the course of that time, although they had been the cause of terrible fighting and bloodshed, they had done much to improve the condition of the Britons. They had made great military roads; they had built forts; they had taught them how to dress, and arm themselves, much better than they had ever known how to do before; they had refined the whole British way of living. Agricola had built a great wall of earth, more than seventy miles long, extending from Newcastle to beyond Carlisle, for the purpose of keeping out the Picts and Scots; Hadrian had strengthened it; Severus, finding it much in want of repair, had built it afresh of stone.
