A note from my OE course page: Burial near the Ridgeway: probably Vikings, possibly killed during the infamous St. Brice's Day Massacre in 1002 (10 Jan. 2011). The other thing to note here is that, as Jonathan Jarrett points out, in spite of their fearsome reputation, we have far more archaeological evidence for the killing of Scandinavians by Englishmen than we do for Englishmen being killed by Vikings, in battle or otherwise.
