Arni Of Mann (cont.)
Battle of Burgh
Main article: Battle of Burgh
Arni assumed command of the Manx army upon
Froði's death, as
Olafr was still in Mann. While still in
Cumberland, they were ambushed by a force of 8,000 Catholic peasants from
Northumbria, who had taken up arms against
Jorvik in an attempt to expel the viking invaders from their homeland. Arni's much smaller force was overwhelmed and forced to retreat, and Arni himself was injured during the battle.
Following the defeat, Arni ordered the army to return to the Isle of Mann to regroup. A letter written to
Gurli before the battle reveals his concern that Olafr would attempt to usurp the throne in his absence, which may have also been a factor in his decision to return to the capital.
Consolidation of Power
Arni was crowned king upon his return to Mann in September 900, with unanimous support of the council. Olafr elected not to challenge Arni for the throne at this time, and Arni's involvement in Froði's death was not yet known.
Arni's first act as king was to appoint
Olafr Þorsteinnsson as spymaster. Olafr was the former chief of
Orknö and
Færeyar, who had been deposed by
Erikr av Hordaland during the
Twenty Year's War. Arni had met Olafr previously while in
Island negotiating a trade agreement and was impressed with his ability. More importantly, he was an outsider with no loyalties toward any existing faction in Mann. Arni promised Olafr his sister
Ingrid's hand in marriage and vowed to restore Olafr to his chiefdoms if he would travel to Mann and serve as spymaster in the interim. This offer was accepted.
Next, Arni set out to dismantle the network of
royal concubines that had wielded significant political power in Mann since the early days of Helgi's reign. Marriages to minor
Scandinavian lords were arraigned for
Alfrið Froðisdottir,
Aslaug Holmgersdottir,
Helen Mac Malmure, and
Donada Mac Ailpin, and all four were sent to live with their new husbands. Of the former concubines, only
Asta and
Heledd, who were too old to remarry, and Gurli, who Arni considered an ally, remained in Mann.
Finally, Arni turned his attention to
Olafr Björnsson, whose ambitions he considered the greatest threat to the realm. Olafr Þorsteinnsson located three men from Galloway willing to testify that they had witnessed Björnsson murder
Geirr, which was by law sufficient evidence to imprison him. Arni believed that Olafr would refuse a summons to court, and would resist if the army was sent to bring him into custody. Arni did not trust his commanders and wished to avoid a military confrontation. Instead he allowed Olafr Þorsteinnsson to spread rumors in
Carrick that he had fallen deathly ill and was preparing to hand the throne to
Refil, anticipating that Björnsson would travel to Mann and attempt to take the throne himself. The plot worked as expected; Olafr arrived in Mann in January 901, and was arrested shortly after. He was thrown into the dungeons, where he would die two years later.
