During the reign of King Beorhtric of Wessex (786–802) three ships of "Northmen" landed at Portland Bay in Dorset. The local reeve mistook the Vikings for merchants and directed them to the nearby royal estate, but the visitors killed him and his men.[18] The earliest recorded planned Viking raid, on 6 January 793,[19] targeted the monastery on the island of Lindisfarne, off the north-east coast of Northumbria.
