Archaeological evidence for the Viking Great Army that invaded England in AD 865 is focused particularly on the area around St Wystan's church at Repton in Derbyshire. Large numbers of burials excavated here in the 1980s have been attributed to the overwintering of the Great Army in AD 873–874. Many of the remains were deposited in a charnel, while others were buried in graves with Scandinavian-style grave goods. Although numismatic evidence corroborated the belief that these were the remains of the Great Army, radiocarbon results have tended to disagree. Recent re-dating of the remains, applying the appropriate marine reservoir correction, has clarified the relationship between the interments, and has resolved the previous uncertainty.
