Fury of the Norse

"The number of ships grows: an endless stream of Vikings never ceases to increase. Everywhere the Christians are victims of massacres, burnings plunderings: the Viking conquers all in their path, and no one resists them. They seize Bordeaux, Perigueux, and Limoges…, Angers, Tours and Orleans are annihilated and an inumberable fleet sails up the Siene and evil grows in the whole region. Rouen is laid waste, plundered and burned; Paris, Beauvais and Meaux taken ..., Bayeux plundered and burned and every town besieged”
