"Wihtburh died in 743 and was buried in the cemetery of Ely abbey.[4] When her body was dug up 55 years later, it was found not to have decayed. This was considered a miracle and her remains were reinterred in the church which she had built in Dereham. The church became a place of pilgrimage, with people visiting Wihtburh's tomb.
In 974 Brithnoth, the abbot of Ely, elected to steal her body so that he could profit from the pilgrims' visits. Brithnoth and some armed men went to Dereham and organised a feast. When the Dereham men were properly drunk, the Ely mob stole Withburga's body and set off for home. Dereham men soon found out that this crime had taken place and set off after the Ely criminals.[5]
The two sides had a pitched fight, using spears as well as fists. As the men approached Ely, however, the thieves had the advantage of knowing their way through the swamps and marshes. They were successful at reinterring Wihtburh in Ely."
