Whilst these events were taking place in the interior of France, the Breton generals, in the vicinity of Normandy, commenced, perhaps in revenge for the incursions of the Scandinavians, ravaging the territory of their neighbours, and invaded the province of Bayeux, but Rollo appeared with his warriors, engaged in battle with the aggressors and conquered them. One of the Breton counts, Beranger, yielded to the Normans; another, Alan, the chief instigator of the war, took refuge in England. The nobles who had fought under these two commanders established themselves in France, in Burgundy, or in Aquitaine; some of them followed Alan to England. All those who remained were obliged to acknowledge the suzerainty of the duke of Normandy. The neighbouring provinces, such as Anjou and Poitou, were henceforth delivered from the hostile irruptions of these turbulent chiefs. Thus, Rollo, in his old age, found himself the peaceful possessor of Normandy, and able to maintain order and peace therein. It is said that Charles the Simple, while he was still upon the throne, secretly sent emissaries to Rouen to his daughter Gisela who had married Rollo; that this clandestine mission gave umbrage to the Normans, and that Rollo seized and publicly put to death the envoys of his father-in-law. Gisela died sometime afterwards; and Rollo lived as before with Popa, by whom he had two children, a son named William, and a daughter called Gerloc, who later received the Christian name of Adela or Adeline. When William grew to man’s estate, the Norman nobles requested their duke to appoint his successor. He named his son, and he it was the Normans had in mind, in spite of his illegitimacy. The nobles swore fidelity and obedience to him beforehand. Rollo lived for five years after this important event, and died of old age at Rouen. The precise date of his death, and also his age, are unknown. Everything tends to show that it was about the year 930, that the death of the first and probably octogenarian duke of Normandy took place. His bravery, his steadfastness, the energy of his government are incontestable, but it is permissible to doubt the truth of the eulogies which the Norman monks in their chronicles have bestowed upon his devotion, and his respect for the clergy. It is possible he enriched the churches and convents, that he walked in processions, and with bare feet before the relics of St. Ouen, formerly taken to France, and which he forced his father-in-law to restore; but on the other hand we read in an English chronicle, that he sold or allowed to be sold many relics belonging to the Norman churches, which were acquired by his ally, Athelstan, king of England.
