Whereupon ambassadors were eftsoon dispatched to Rome, lamentably beseeching that they would not suffer their miserable country to be utterly destroyed: then again another legion was sent, which coming upon a sudden, made a great slaughter of the enemy, and chased him home, even to his own country. These Romans at their departure, told the Britons plainly, that it was not for their ease or leisure to take upon them any more such long and laborious journeys for their defence, and therefore bade them practice the use of armour and weapons, and learn to withstand their enemies, whom nothing else did make so strong as their faint heart and cowardice; and for so much as they thought that it would be no small help and encouragement unto their tributary friends whom they were now forced to forsake,[12] they built for them a wall of hard stone from the west sea to the east sea, right between those two cities, which were there made to keep out the enemy, in the selfsame place where Severus before had cast his trench. The Britons also putting to their helping hands as labourers. This wall they built eight feet thick in breadth, and twelve feet in height, right, as it were by a line, from east to west, as the ruins thereof remaining in many places until this day do make to appear. Which work, thus perfected, they give the people strait charge to look well to themselves, they teach them to handle their weapons, and they instruct them in warlike feats. And lest by the sea-side southwards, where their ships lay at harbour, the enemy should come on land, they made up sundry bulwarks, each somewhat distant from the other, and so bid them farewell, as minding no more to return. This happened in the days of the Emperor Theodosius the younger, almost 500 years after the first arrival of the Romans here, about the year after Christ’s incarnation 434.
