When King Inge and his men saw that Gregorius was aground, he encouraged his crew to row to his assistance.
"the most imprudent advice that we should remain lying here, while our friends are in battle; for we have the largest and best ship in all the fleet.
But now I see that Gregorius, the man to whom I owe the most, is in need of help; so we must hasten to the fight where it is sharpest. It is also most proper that I should be in the battle; for the victory, if we win it, will belong to me.
And if I even knew beforehand that our men were not to gain the battle, yet our place is where our friends are; for I can do nothing if I lose the men who are justly called the defence of the country, who are the bravest, and have long ruled for me and my kingdom."
Thereupon he ordered his banner to be set up, which was done; and they rowed across the river. Then the battle raged, and the king could not get room to attack, so close lay the ships before him. First he lay under the East-country trading ship, and from it they threw down upon his vessel spears, iron-shod stakes, and such large stones that it was impossible to hold out longer there, and he had to haul off.
Now when the king's people saw that he was come they made place for him, and then he laid alongside of Eindride Jonson's ship. Now King Hakon's men abandoned the small ships, and went on board the large merchant vessels; but some of them sprang on shore.
Erling Skakke and his men had a severe conflict. Erling himself was on the forecastle, and called his forecastlemen, and ordered them to board the king's ship; but they answered, this was no easy matter, for there were beams above with an iron comb on them. Then Erling himself went to the bow, and stayed there a while, until they succeeded in getting on board the king's ship: and then the ship was cleared of men on the bows, and the whole army gave way. Many sprang into the water, many fell, but the greater number got to the land.
So says Einar Skulason: —
"Men fall upon the slippery deck —
Men roll off from the blood-drenched wreck;
Dead bodies float down with the stream,
And from the shores witch-ravens scream.
The cold blue river now runs red
With the warm blood of warriors dead,
And stains the waves in Karmt Sound
With the last drops of the death-wound.
"All down the stream, with unmann'd prow,
Floats many an empty long-ship now,
Ship after ship, shout after shout,
Tell that Kign Hakon can't hold out.
The bowmen ply their bows of elm,
The red swords flash o'er broken helm:
King Hakon's men rush to the strand,
Out of their ships, up through the land."
Einar composed a song about Gregorius Dagson, which is called the River-song. King Inge granted life and peace to Nikolas Skialdvarson when his ship was deserted, and thereupon he went into King Inge's service, and remained in it as long as the king lived. Eindride Jonson leaped on board of King Inge's ship when his own was cleared of men, and begged for his life. King Inge wished to grant it; but Havard Klining's son ran up, and gave him a mortal wound, which was much blamed; but he said Eindride had been the cause of his father's death.
There was much lamentation at Eindride's death, but principally in the Throndhjem district. Many of Hakon's people fell here, but not many chiefs. Few of King Inge's people fell, but many were wounded. King Hakon fled up the country, and King Inge went north to Viken with his troops; and he, as well as Gregorius, remained in Viken all winter (A.D. 1160).
When King Inge's men, Bergliot and his brothers, sons of Ivar of Elda, came from the battle to Bergen, they slew Nickolas Skeg, who had been Hakon's treasurer, and then went north to Throndhjem.
King Hakon came north before Yule, and Sigurd was sometimes home at Reyr; for Gregorius, who was nearly related to Sigurd, had obtained for him life and safety from King Inge, so that he retained all his estates.
King Hakon was in the merchant-town of Nidaros in Yule; and one evening in the beginning of Yule his men fought in the room of the court, and in this affray eight men were killed, and many were wounded. The eighth day of Yule, King Hakon's man Alf Rode, son of Ottar Birting, with about eighty men, went to Elda, and came in the night unexpectedly on the people, who were very drunk, and set fire to the room; but they went out, and defended themselves bravely.
There fell Bergliot, Ivar's son, and Ogmund, his brother, and many more. They had been nearly thirty altogether in number. In winter died, north in the merchant-town, Andres Simonson, King Hakon's foster- brother; and his death was much deplored. Erling Skakke and Inge's men, who were in Bergen, threatened that in winter they would proceed against Hakon and his men; but it came to nothing.
Gregorius sent word from the east, from Konungahella, that if he were so near as Erling and his men, he would not sit quietly in Bergen while Hakon was killing King Inge's friends and their comrades in war north in the Throndhjem country.
