Heimskringla > part in the government with his brother Hardaknut. In the same autumn > 3. King Eirik'S Expedition To Norway.
- attestation: In Viken, King Inge's lendermen under Vatnorm Dagson opposed the Danish fleet, killing many Danes who tried to land for water.
"a great number of King Inge's lendermen came against them. Their leader was Vatnorm Dagson, a brother of Gregorius. The Danes could not land to get water without many of them being killed"
Heimskringla > part in the government with his brother Hardaknut. In the same autumn > 5. Of Sigurd Slembidjakn.
attestation: At Portyrja, Tunsberg men surprised Sigurd while dividing booty on shore, but he escaped with one ship after Vatnorm's ship fell behind the blockade line.
"Vatnorm's ship was the nearest, and he let his ship fall behind the line, and Sigurd rowed clear past, and thus escaped with one ship and the loss of many men."
attestation: A punning verse was made about Vatnorm ('water serpent') slipping away from Portyrja, playing on his name.
""The water serpent, people say, From Portyrja slipped away.""
