King Olaf had in his ship 100 men armed in coats of ring-mail, and in foreign helmets. The most of his men had white shields, on which the holy cross was gilt; but some had painted it in blue or red.
He had also had the cross painted in front on all the helmets, in a pale colour. He had a white banner on which was a serpent figured. He ordered a mass to be read before him, went on board ship, and ordered his people to refresh themselves with meat and drink. He then ordered the war-horns to sound to battle, to leave the harbour, and row off to seek the earl.
Now when they came to the harbour where the earl had lain, the earl's men were armed, and beginning to row out of the harbour; but when they saw the king's fleet coming they began to bind the ships together, to set up their banners, and to make ready for the fight. When King Olaf saw this he hastened the rowing, laid his ship alongside the earl's, and the battle began.
So says Sigvat the skald: —
"Boldly the king did then pursue
Earl Svein, nor let him out of view.
The blood ran down the reindeer's flank
Of each sea-king — his vessel's plank.
Nor did the earl's stout warriors spare
In battle-brunt the sword and spear.
Earl Svein his ships of war pushed on,
And lashed their stout stems one to one."
It is said that King Olaf brought his ships into battle while Svein was still lying in the harbour. Sigvat the skald was himself in the fight; and in summer, just after the battle, he composed a lay, which is called the "Nesjar Song", in which he tells particularly the circumstances: —
"In the fierce fight 'tis known how near
The scorner of the ice-cold spear
Laid the Charles' head the earl on board,
All eastward of the Agder fjord."
Then was the conflict exceedingly sharp, and it was long before it could be seen how it was to go in the end. Many fell on both sides, and many were the wounded.
So says Sigvat: —
"No urging did the earl require,
Midst spear and sword — the battle's fire;
No urging did the brave king need
The ravens in this shield-storm to feed.
Of limb-lopping enough was there,
And ghastly wounds of sword and spear.
Never, I think, was rougher play
Than both the armies had that day."
The earl had most men, but the king had a chosen crew in his ship, who had followed him in all his wars; and, besides, they were so excellently equipped, as before related, that each man had a coat of ring-mail, so that he could not be wounded.
So says Sigvat: —
"Our lads, broad-shouldered, tall, and hale,
Drew on their cold shirts of ring-mail.
Soon sword on sword was shrilly ringing,
And in the air the spears were singing.
Under our helms we hid our hair,
For thick flew arrows through the air.
Right glad was I our gallant crew,
Steel-clad from head to foot, to view."
