Vagn Åkesson was a Norseman of the late 10th century, mentioned in the Jómsvíkinga saga.
At the age of 12, Vagn, a warrior, applied for admission to the mercenary brotherhood of the Jomsvikings.
He was admitted to the order despite the Jomsviking rule that no man under the age of 18 be allowed to join.
Vagn's courage stands in sharp contrast to the pragmatism (some would say cowardice) displayed by Sigvaldi.
Vagn managed to survive the battle with honor and was spared by Eiríkr Hákonarson, while Sigvaldi became the object of ridicule.
