When London reappears, it is in humble guise: the City has shrunk within her ancient walls; and these have fallen into decay. Southwark no longer exists. We learn that the Bridge has been repaired, because there is easy communication with Canterbury. Yet in the Danish troubles there is no fighting on or for the Bridge. Why? simply because there were no defenders of the Bridge on the south. In 819 and in 857 the Danes entered London and 'slaughtered numbers,' apparently without opposition. In 872 they occupied London, apparently without opposition. We hear of no siege, of no fighting on the Bridge; of no shelter behind the walls. Yet there was a defence at York, at Reading, at Nottingham--behind the walls. Why not in London? Because in London the walls, 5,500 yards in length, had become too long to man, or to defend, or to repair. The Danes ran into the City through the shattered gate; they leaped over the broken wall. What happened to the people; what street fighting was carried on, what slaughter, what plunder, what horrible treatment of women--we may understand from the page of the historian Saxo relating other sacks and sieges by the gentle Dane. As for the trade, the wealth, the name and fame of London--they all perished together. It was a ruined city, with a miserable population of craftsmen enslaved by the Dane, that Alfred reconquered. The Bridge itself was broken down; the settlements of the south were deserted: even the fishermen had left the Thames above and below London, and sought for safety in the retired creeks and safe backwaters along the coast of Essex. The London fisherman sallied forth in his coracle from the marshes behind Canvey Island, and from the slopes of Hadleigh. Alfred repaired the walls and the Bridge and rebuilt the gates. Something like peace was restored to the City and order to the country. Then trade, which welcomes the first appearance of safety, began again. If the merchant feared the pirates of the Foreland, he could march across the Bridge to Dover; or he could land at Dover and march across Kent to the Bridge. Then the old settlements on the south Causeway were rebuilt and new inns sprang up, and Southwark began again. A hundred years of rest from the 'army,' as the 'Chronicle' calls the Danes, gave Southwark time to grow. It is spoken of by the Danish historian as an 'emporium.' I understand from the use of this word that the trade of London was carried on principally by way of Dover, because the seas were swarming with pirates. Southwark was a halting-place and a resting-place, such as Thorney had been of old.
