When the Swedish king heard this he drew together people, and the report came that he would ride against these Northmen; but there was delay about his riding, and the Northmen made these lines: —
"The fat-hipped king, with heavy sides,
Finds he must mount before he rides."
But when the ice set in upon the Vener lake King Inge rode down, and had near 300 men with him. He sent a message to the Northmen who sat in the burgh that they might retire with all the booty they had taken, and go to Norway. When the messengers brought this message, Sigurd Ulstreng replied to it; saying that King Inge must take the trouble to come, if he wished to drive them away like cattle out of a grass field, and said he must come nearer if he wished them to remove.
The messengers returned with this answer to the king, who then rode out with all his army to the island, and again sent a message to the Northmen that they might go away, taking with them their weapons, clothes, and horses; but must leave behind all their booty. This they refused. The king made an assault upon them, and they shot at each other.
Then the king ordered timber and stones to be collected, and he filled up the ditch; and then he fastened anchors to long spars which were brought up to the timber-walls, and, by the strength of many hands, the walls were broken down. Thereafter a large pile of wood was set on fire, and the lighted brands were flung in among them. Then the Northmen asked for quarter. The king ordered them to go out without weapons or cloaks.
As they went out each of them received a stroke with a whip, and then they set off for Norway, and all the forest-men submitted again to King Inge. Sigurd and his people went to King Magnus, and told him their misfortune.
