The Danes suffered him to pursue this course until he had amassed great wealth, when they swooped down upon him, robbed him of all he possessed, and took away the nominal kingship he had held. As there was now but little fresh scope for plundering in England many of the Danes both in Anglia and Mercia settled down in the cities and on the lands which they had taken from the Saxons. The Danes who had gone from Exeter were now joined by another band which had landed in South Wales. The latter, finding but small plunder was to be obtained among the mountains of that country, moved to Gloucester, and joining the band there proposed a fresh invasion of Wessex. The Danes, in spite of the oaths they had sworn to Alfred, and the hostages they had left in his hands, agreed to the proposal; and early in the spring of 878 the bands, swollen by reinforcements from Mercia, marched into Wiltshire and captured the royal castle of Chippenham on the Avon. From this point they spread over the country and destroyed everything with fire and sword. A general panic seized the inhabitants. The better class, with the bishops, priests, and monks, made for the sea-coasts and thence crossed to France, taking with them all their portable goods, with the relics, precious stones, and ornaments of the churches and monasteries. Another party of Danes in twenty-three ships had landed in Devonshire. Here the ealdorman Adda had constructed a castle similar to that which Edmund had built. It was fortified by nature on three sides and had a strong rampart of earth on another. The Danes tried to starve out the defenders of the fort; but the Saxons held out for a long time, although sorely pressed by want of water. At last they sallied out one morning at daybreak and fell upon the Danes and utterly defeated them, only a few stragglers regaining their ships. A thousand Danes are said to have been slain at Kynwith; but this was an isolated success; in all other parts of the kingdom panic appeared to have taken possession of the West Saxons. Those who could not leave the country retired to the woods, and thence, when the Danes had passed by, leaving ruin and desolation behind them, they sallied out and again began to till the ground as best they could. Thus for a time the West Saxons, formerly so valiant and determined, sank to the condition of serfs; for when all resistance ceased the Danes were well pleased to see the ground tilled, as otherwise they would speedily have run short of stores.
