In 1228 John sent presents to the Norse king, and received in return a good long-ship and many other gifts; and in 1230 John is found aiding Olaf, King of Man, a friend of the Norse king, by giving him a like vessel, “The Ox,” to enable him to complete his voyage back from Norway to his own kingdom, and in the same year John rendered assistance to the Norse expedition, which had attacked the South Hebrides, by harbouring its ships in Orkney on their voyage back to Norway.[17]

From the above facts it is clear that Earl John, though he owed allegiance to both kings, was more inclined to favour Norway than Scotland, and that he was more constantly in attendance at the Norse, than at the Scottish Court.  At the same time it became more and more likely that he would have to choose between his two masters, as war for the Sudreyar or Hebrides was already certain to break out between the two countries, and, save for civil war in Norway, would have broken out at once.

Snaekoll[18] Gunni’s son, as the sole male representative of the Erlend Thorfinnson, St. Magnus, St. Ragnvald, Eric Stagbrellir and Harald Ungi line remaining in Scotland, who had probably about this time succeeded, or at least was recognised as next heir to the Moddan family estates in Strathnaver and Caithness, approached Earl John in 1231, and demanded from him Jarl Ragnvald’s lands in Orkney.  But the earl, who held Orkney in its entirety as the representative of the line of Paul and of Harold Maddadson, who had seized it when Jarl St. Ragnvald died in 1158, refused to give Snaekoll any part of those lands; and Snaekoll, failing to obtain any redress, sought the aid of Hanef, formerly a page, but now Commissioner in Orkney, of the Norse King, and demanded his help in recovering his lands there.  Snaekoll and Hanef with a large following accordingly crossed the Pentland Firth to Thurso to enforce the claim, but the earl again angrily refused to restore the lands in Orkney, and it would seem that he was also unwilling to let Snaekoll have his rights in Caithness.[19]

Each party occupied separate lodgings in Thurso with their separate followings, and Hanef and his friends, warned by a messenger of the earl’s reported design of killing them, forestalled it by attacking the earl first, and they slew him with nine wounds in the cellar of his lodgings.  After the affray they crossed over to Orkney, where they fortified the small but massive castle[20] or tower of Kolbein Hruga or Cobbie Row, in the Island of Vigr or Wyre, now called Veira, near Rousay in Orkney, and provisioned it for a siege, which lasted the whole winter, and was raised only after both sides had come to an agreement that all questions arising out of the earl’s death at Thurso, should be referred, not to the Scottish courts, but to the Norse king, Hakon, in Bergen.
