What happened during this long interval of seven generations? Not a word reaches us of London for two hundred years except once when, after a defeat of the British by the Saxons at Crayford in the year 457, we read that the fugitives crossed over London Bridge to take refuge within the walls of the City. What happened during this two hundred years?[1] We know what happened with other cities. Anderida, now called Pevensey, was taken by the Saxons, and all its inhabitants, man, woman and child, were slaughtered, so that it became a waste until the Normans built a castle within the old walls. Canterbury, Silchester, Porchester, Colchester--all were taken, their people massacred, the walls left standing, the streets left desolate. For the English--the Saxons--loved not city walls. Therefore, we might reasonably conclude that the same thing happened to London. But if it be worthy of the chronicler to note the massacre of Anderida, a small seaport, why should he omit the far more important capture of Augusta? [1] On this subject, see the author's book _London_ (Chatto & Windus). Let us hear what history has to tell. Times full of trouble fell upon the country. Long before the Romans went away the Picts and Scots were pouring their wild hordes over the north and west, sometimes getting as far south as the Middlesex Forest, murdering and destroying. As early as the year 368, forty years before they left the country, the Romans sent an expedition north to drive back these savages. Already the Saxons, the Jutes and the Angles were sending piratical expeditions to harry the coast and even to make settlements. The arm of the Roman was growing weak, it could not stretch out so far: the fleets of the Romans, under the officer called the 'Count of the Saxon Shore'--whose duty was to guard the eastern and southern coasts--were destroyed and their commander slain. So that, with foes on the eastern seaboard, foes in the Channel, foes in the river, foes in the north and west, it is certain that the trade of Augusta was declining long before the City was left to defend itself.
