[1, 5] okkur; vér ‘our; we’: The contrast between the dual pron. in l. 1 and the pl. in l. 5 may not be significant (the dual form is required in l. 1 for the skothending). If it is, then the first helmingr refers to Rǫgnvaldr and Erlingr leading the attack, while the second helmingr refers more generally to the valour of the whole company.
