Within days of Óláfr's arrival in Norway, the saga reveals that Óspakr's fleet set sail for the Isles, and swelled in number after reaching Orkney. Whilst the "Eirspennill" version of the saga numbers the fleet in Norway at twelve ships, the "Flateyjarbók", "Frísbók", and "Skálholtsbók" versions give the number eleven; and whilst the former version relates that the fleet gained twenty ships from Orkney, the latter three versions state that the fleet numbered twenty when it left Orkney. The saga recounts that Óláfr and Páll journeyed on the same ship, and states that, after they reached Orkney, Jón Haraldsson, Earl of Orkney gave Óláfr a ship called the "Ox". Once in the Isles, the fleet linked up with three leading members of Clann Somhairle on Islay.
