According to the
Annales and
Historiae, Hagrold captured Louis in 945, after which Hugh eventually secured the king's release through negotiations. The fact that Hagrold is described as in charge of Bayeux in these accounts suggests that he led the successful defence of the town in the preceding year. He was clearly a considerably powerful figure to have not only gained power but withstand Frankish aggression. At this point in history, even before William's assassination, Norman comital power encompassed little more than the outskirts of
Rouen. Hagrold—apparently a pagan from Scandinavia—seems to have ruled Bayeaux as his personal domain, and apparently stood independent from both the Franks and Normans. The political disarray in Denmark at about this time would have likely contributed to such settlement in Normandy, and could account from Hagrold's presence there. The successive waves of Scandinavian settlers into Lower Normandy during this period likely contributed to the lack of comital power. On one hand, it is possible that, following William's death, Hagrold seized control of parts of the
Cotentin with foreign support, and extended his authority to Bayeux. On the other hand, Hagrold may have operated in the context of aiding the Normans of Rouen to oppose the Franks. Although he likely defended Bayeux from Louis and Hugh in 944, Hagrold's capture of Louis the following years suggests that he volunteered to assist Hugh against the king. Religious affiliations played appear to have been factor in the political alignments of tenth-century Normandy. According to the
Annales, many pagans from Scandinavia arrived in Normandy in 943, leading some Normans to revert from
Christianity to
paganism. Long after Hagrold's
floruit, Norman secular and ecclesiastical authority in Bayeux remained precarious. Hagrold appears on record as late as 954, when Richard and Hugh are recorded to have attacked Bayeux. What came of Hagrold is uncertain. One possibility is that he and his family removed to the
Irish Sea region, and that his descendants were the Meic Arailt, a family that contested control of this region with the Meic Amlaíb branch of the
Uí Ímair. On the other hand, the evidence concerning the Meic Arailt seems to indicate that this family—represented in the second generation by
Gofraid mac Arailt and
Maccus mac Arailt—was merely a branch of the Uí Ímair itself. ==Later interpretations==
