When the dust-cloud approached nearer they knew their own men, who were driving the cattle. The Irish king had been faithful to the promises he had given the king, and had sent them. Thereupon they all turned towards the ships, and it was mid-day. When they came to the mires they went but slowly over the boggy places; and then the Irish started up on every side against them from every bushy point of land, and the battle began instantly.
The Northmen were going divided in various heaps, so that many of them fell.
Then said Eyvind to the king,
"Unfortunate is this march to our people, and we must instantly hit upon some good plan."
The king answered,
"Call all the men together with the war-horns under the banner, and the men who are here shall make a rampart with their shields, and thus we will retreat backwards out of the mires; and we will clear ourselves fast enough when we get upon firm ground."
The Irish shot boldly; and although they fell in crowds, there came always two in the place of one. Now when the king had come to the nearest ditch there was a very difficult crossing, and few places were passable; so that many Northmen fell there.
Then the king called to his lenderman Thorgrim Skinhufa, who was an Upland man, and ordered him to go over the ditch with his division.
"We shall defend you,"
"in the meantime, so that no harm shall come to you. Go out then to those holms, and shoot at them from thence; for ye are good bowmen."
When Thorgrim and his men came over the ditch they cast their shields behind their backs, and set off to the ships.
When the king saw this, he said,
"Thou art deserting thy king in an unmanly way. I was foolish in making thee a lenderman, and driving Sigurd Hund out of the country; for never would he have behaved so."
King Magnus received a wound, being pierced by a spear through both thighs above the knees. The king laid hold of the shaft between his legs, broke the spear in two, and said,
"Thus we break spear-shafts, my lads; let us go briskly on. Nothing hurts me."
A little after King Magnus was struck in the neck with an Irish axe, and this was his death-wound. Then those who were behind fled. Vidkun Jonson instantly killed the man who had given the king his death-wound, and fled, after having received three wounds; but brought the king's banner and the sword Legbit to the ships. Vidkun was the last man who fled; the other next to him was Sigurd Hranason, and the third before him, Dag Eilifson.
There fell with King Magnus, Eyvind Olboge, Ulf Hranason, and many other great people. Many of the Northmen fell, but many more of the Irish. The Northmen who escaped sailed away immediately in autumn. Erling, Earl Erlend's'son, fell with King Magnus in Ireland; but the men who fled from Ireland came to the Orkney Islands. Now when King Sigurd heard that his father had fallen, he set off immediately, leaving the Irish king's daughter behind, and proceeded in autumn with the whole fleet directly to Norway.
