According to Bede, writing at the beginning of the eighth century, Essex, Sussex and Wessex were planted by the Saxons; East Anglia, Mercia and Northumbria by the Angles; the Jutes took Kent and the Isle of Wight. They could be ruthless. Sometimes, as at Pevensey Castle, for instance, an ancient Roman fort in which the Celts took refuge, it is recorded that every man, woman and child was slaughtered by these invaders. Much the same happened in what became England, between AD 500 and, say, AD 750, to the native Celtic language.
