 According to Njal's Saga, Óspak was on the wing opposite King Sigtrygg Silkbeard. Óspak went through the entire battle on this wing, and was sorely wounded and lost both his sons before Sigtrygg fled. However, that Óspak engaged Sigtrygg contradicts the historical opinion that Sigtrygg did not actually take part in the battle but was instead holding the garrison in reserve in Dublin.
