Despite remaining on the list of Roman provinces, Romano-Britain seems to have dropped their remaining loyalties to Rome. Raiding by the Irish, Picts, and Saxons continued but Gildas records a time of luxury and plenty which is sometimes attributed to reduced taxation. Archaeologists have found evidence that a small number of wealthy families continued to maintain a Roman lifestyle until the middle of the 5th century, inhabiting villas in the southeastern corner of the city and importing luxuries. Medieval accounts state that the invasions that established Anglo-Saxon England (the "Adventus Saxonum") did not begin in earnest until some time in the 440s and 450s. Bede recorded that the Britons fled to Londinium in terror after their defeat at the Battle of Crecganford (probably Crayford), but nothing further is said. By the end of the 5th century, the city was largely an uninhabited ruin, its large church on Tower Hill burnt to the ground.
