Cause → Event → Consequence
Danish Viking armies had been raiding and pressing into English territory during the mid-ninth century. By 871 a large Viking force, led by Bagsecg and Halfdan, was operating in Berkshire, threatening the West Saxon kingdom and prompting a military response from King Æthelred and his brother Alfred.
On approximately 8 January 871, West Saxon forces under King Æthelred and Alfred engaged a Danish Viking army at a location known as Ashdown, believed to be in Berkshire, possibly at Kingstanding Hill or near Starveall south of Lowbury Hill. The battle resulted in a clear West Saxon victory over the Viking force.
The victory at Ashdown demonstrated that the West Saxons could defeat Viking armies in open battle, and it contributed to the early military reputation of Alfred, who would later become King Alfred the Great and the principal defender of England against Viking encroachment in the later ninth century.
