In 851, a large Danish Viking force raided southern England, arriving in a fleet reportedly drawn from 350 ships. The Danes had already struck elsewhere in the kingdom, prompting Kentish forces under the under-king Æthelstan and Ealdorman Ealhhere to mount a coordinated naval response off the coast of Kent.
King Æthelstan of Kent and Ealdorman Ealhhere engaged a Danish fleet in ship-borne combat off Sandwich in Kent. Their forces slew a large number of the enemy, captured nine Danish ships, and drove the remainder to flight, constituting the first recorded naval battle in English history.
The Kentish victory at Sandwich demonstrated that English forces could meet Viking raiders at sea rather than only on land. Nine enemy ships were taken as prizes, inflicting a significant material and morale blow on the Danes, and the engagement was recorded in the Anglo-Saxon Chronicle as a notable military success.
