The battle was won clearly by the Norwegians, but since many Danes managed to escape, including Sweyn, it proved indecisive in Harald's attempt to conquer Denmark.

[2][3][4] According to the Icelandic saga writer Snorri Sturluson, the battle had been preassigned a time and place, but Sweyn did not appear as agreed.

Sweyn had no similar reserve force, and his fleet was defeated by dawn, with 70 ships left "empty" and the remainder retreating.

While Finn Arnesson fought until he was captured, Sweyn jumped into the water and was rescued by his former ally Haakon (albeit unknowingly to Harald).

[7] Although Harald won the battle, the victory was not decisive since many Danish ships and men had managed to escape, including Sweyn.
