[All]: It is not documented in any source that Waltheof fought at the battle of Hastings; rather, it seems that this st. documents a completely different event—the sacking of York on 21 September 1069. On that occasion, Waltheof and other Engl. noblemen joined Danes who had been sent by King Sveinn Úlfsson of Denmark in a revolt against William. The Danes and their Engl. allies, among them Waltheof, attacked York and the forces which William had left behind in the stronghold (see ASC s. a. 1068 ( ‘D’), 1069 (‘E’)). According to Chronicle ‘D’, the rebels demolished the castle. The entire town, including the minster of St. Peter, was destroyed by fire and hundreds of Normans perished. That fire was, however, set by the Normans themselves (on these events, see also Scott 1952, 166-7, 174-81).
