In 874 Halfdan took his followers north to camp at the mouth of the River Tyne. They raided the Picts and Britons in Strathclyde for the next year. But there was little gain in raiding these poorer areas. The Danes had plundered the wealth of most of England and little was left. Halfdan began settling his men in the area of York. The other army led by Gutheram, Oscytel and Arnuld was still fighting against Wessex at the time. By 876 they had concluded a peace with Wessex. In late 878 Guthrum's band withdrew to Cirencester in Mercia. In 879 they moved to East Anglia. The leader Guthrum, known by his Christian name Aethelstan, reigned as king until his death in 890. According to the Anglo-Saxon Chronicle 'they occupied the land and shared it out.' In 878 a new Danish army was camped at Fulham. But by 879 they had left England for the Low Countries.
