The Anglo-Saxon Chronicle records for 855 that "heathens for the first time remained over winter in Sheppey." This is a pivotal moment: Vikings were no longer just seasonal raiders but were beginning to overwinter and use England as a base. It directly prefigures the arrival of the Great Heathen Army fourteen years later. Sheppey's position at the Thames estuary made it the natural first step.
Danish Viking force c. 2,000-3,000 overwintering on Sheppey.
