Brice, St, Bishop of Tours in the beginning of the 5th century, is commemorated as a confessor. St Brice's Day, in 1002 (in the reign of Ethelred II.), is notorious in old English history for a great massacre of the Danes. It was believed that it was a concerted attempt to exterminate all the Danes in England; but failing of its bloody purpose, it led to reprisals by the Danish king Sweyn.
