[King Lyngvi] and his brothers went against Sigurd with a mighty force, and then the fiercest of battles began between them. Masses of spears and arrows could be seen flying through the air; axes swung violently, shields were split, armor was cut open, helmets were slashed, and skulls were cloven. Many men fell to the ground.
When the battle had gone on a very long time, Sigurd advanced past the standards, holding in his hand the sword Gram. He hewed both men and horses and went through the ranks, so that both his arms were bloody to the shoulder.
