During this reign, after the battle of Hafsfjord, the great viking “Rolf Ganger,” son of Earl Rognvald, having offended King Harald, was banished from Norway, and, in company with many other Northmen, sailed with a fleet of vessels to the Hebrides, and from thence to Normandy, where the Northmen, about the year 896, obtained possession of Rouen, and Rolf Ganger, afterwards embracing Christianity, became Duke of Normandy.—Histoire de la Conquête de l’Angleterre par les Normans, par Augustin Thierry, vol. i. p. 114.
