A. 875. Lastly after a year, the barbarians divide the kingdom into two parts: and Halfdene the leader of the barbarians took one part, namely the kingdom of the Northumbrians, and there he chose his winter-quarters near the river called the Tyne, and they ravaged the country there on every side. But they also made frequent wars on the Picts and the men of Cumberland. Oskytel also, and Gothrun, and Anwiund, their three kings, with an immense army, came from Repton to a place called Grantabridge [Cambridge], and there remained twelve months. Furthermore in the summer of the same year, king Alfred came out with his army on board a fleet by sea, and the barbarians met them with seven tall vessels. A battle ensues, and the Danes are routed: the king takes one of their ships. A. 876. After one year, the tyrant Halfdene obtained the kingdom of the Northumbrians, all of whom he reduced to subjection. And in the course of the same year, the army which had been at Cambridge made a junction with the western army, a thing which they had not done before, near the town which is called Wareham, and ravaged the greater part of that province. Also the king ratified a treaty of peace with them and gave them money. But they gave him hostages chosen out of their army, and made oath to him on their sacred bracelet which they had never done to the kings of the other districts, that they would quickly leave their territories. A. 877. But they broke the peace and contravened their engagements, and the following year extended their troops into the province of Devon, where they passed the winter at Exeter. Lastly their fleets put to sea and spread their sails to the wind: but a lamentable storm came on, and the greatest part of them, namely a hundred of their chief ships, were sunk near the rock which is called Swanwich. The barbarians renew their fraud and offer peace: hostages were given, more than were demanded, to the effect that they would withdraw out of the territories of king Alfred; and they did so. They devastate the kingdom of the Mercians and drive out all the free men. They erect their huts in the town of Gloucester.
