The first Viking raid on Anglo-Saxon England is thought to have been between 786 and 802 at Portland in the Kingdom of Wessex, when three Norse ships arrived; their men killed King Beorhtric's reeve. At the other end of the country, in the Kingdom of Northumbria, during 793 the holy island of Lindisfarne was raided. After the sacking of Lindisfarne, Viking raids around the coasts were somewhat sporadic until the 830s, when the attacks became more sustained. In 835, "heathen men" ravaged Sheppey. In 836, Ecgberht of Wessex met in battle a force of 35 ships at Carhampton, and in 838 he faced a combined force of Vikings and Cornishmen at Hingston Down in Cornwall.
