afterwards intervened between the duke and count, ''Gesta Normannorum ducum'' records that Lagmann and Óláfr were presented with gifts from the king, and persuaded to return home to their own countries.
The accounts of Lagmann and Óláfr suggest that they were
sea-kings, the royal commanders of Viking fleets that sought out plunder, mercantile wealth, and mercenarial employment.

The exact chronology of the events attributed to Lagmann on the Continent is uncertain. There is reason to suspect that the episode concerning 1014 may be erroneous, and actually refers to Óláfr's otherwise known campaigning with
Þorkell inn hávi in 1009–1011. Certainly, no English source associates Óláfr with Knútr in 1014, at about the time when the former was active in Scandianvia claiming the

. Although it is likewise uncertain who ruled the Isles at about the time of the Battle of Clontarf, it is conceivable that Lagmann held a degree of authority on Mann. The royal title accorded to him by ''Gesta Normannorum ducum'' suggests that had ruled in the Kingdom of the Isles, or at least possessed a claim to the kingship.
[ Wadden (2015) p. 30.] One possibility is that his actions in England and on the Continent are evidence that he had been exiled from the Isles by this time. Such an expatriation could have come about in the immediate aftermath of the death of Ragnall in 1005. If correct,

Brian Boru ( mga, Brian Bóruma mac Cennétig; modern ga, Brian Bóramha; 23 April 1014) was an Irish king who ended the domination of the High Kingship of Ireland by the Uí Néill and probably ended Viking invasion/domination of Ireland. Bri ...
could have seized upon Ragnall's demise and forced Lagmann from the Isles in an attempt to wrest control of realm for himself. The fact that the ''Annals of Ulster'' describes Brian in 1014 as "over-king of the Gaels of Ireland, and of the Foreigners, and of the Britons" could be evidence that Brian indeed held authority in the Isles, or at least sought to. It is conceivable that such interference could have enticed certain Islesmen to back Sitriuc and the Dubliners against Brian at the Battle of Clontarf that year.

If Lagmann and his son died at about the same time, the lack of a suitable native candidate to succeed as King of the Isles may account for the record of the region falling under the control of the Norwegian

[ Hudson (2005) p. 132.] Evidence that Knútr installed Hákon as overlord of the Isles may be preserved by the twelfth-century ''

, enjoyed the military assistance of the ''Hibernenses''. Although this particular passage purports to describe events in the late tenth-century, it is evident that the source is heavily influenced by the realities of the early eleventh century.
Whilst there is no evidence that Richard I had access to Irish support, there is instead reason to suspect that ''Gesta Normannorum'' actually refers to the Norse-Gaelic rulers of the Kingdom of the Isles and the Irish Sea region. In fact, it is possible that Richard II's association with Lagmann influenced the passage connecting Richard I with a military alliance with the ''Hibernenses''.
In another passage, ''Gesta Normannorum'' alleges that Richard I was involved in securing peace between the English and the ''Hibernenses''. Certainly, a papal directive of 991 reveals that the English and Normans concluded a peace treaty in which the duke was called upon to resist from aiding the enemies of the English. Together, this pact and ''Gesta Normannorum'', may indicate that Richard I was associated with leading figures in the Irish Sea region, such as Lagmann's father and uncle,
Maccus mac Arailt
Maccus mac Arailt (fl. 971–974), or Maccus Haraldsson, was a tenth-century King of the Isles. Although his parentage is uncertain, surviving evidence suggests that he was the son of Harald Sigtryggson, also known as Aralt mac Sitriuc, the Hibe ...
. The latter two were actively campaigning in the Irish Sea region in the 970s and 980s. As such, Lagmann may have continued his family's cooperation with the dukes of Normandy.
Another source that seems to evince military collaboration between the Isles and Normandy is the eleventh-century ''

''. Although the reliability of this chronicle is suspect, it nevertheless relates that Richard II enjoyed an amiable alliance and military assistance from "the islands beyond the sea", and may partly evince links between the Normans and the Irish Sea region.
