When Eric caught wind of this he rallied his men giving inspiring speeches and promising victory, Eric would not assail all of Magnus fleet at once but would destroy portions of the fleet as it arrived, therefore he ordered attacks on the isolated frontal portions, defeating each part in detail.

Alas when Magnus caught wind of this, he acted decisively, he immediately anchored and lowered his sails, he gathered his entire fleet packing it tightly.

Even though the fighting was tough, the outcome of the battle was obvious, so the greatest warriors in Magnus fleet pushed towards were the fighting was fiercest and pulled their king away from the frontlines of the carnage, in last charge the Housecarls managed to break through this "siege", every single ship but the one in which Magnus escaped was captured or destroyed.
