The strategy leading up to the Burning is characteristic of Sweyn and his stratagems. He _openly_ asks for ships and sails in them, and thus is expected to land on the coast. But after a purposely devious course, which has puzzled inquirers into the locality of Ekkjals-bakki, he came overland by Oykel and Lairg and Strathnaver or Strathskinsdale, whence he was not looked for. Thorbiorn Klerk next has his revenges. First he burnt Earl Waltheof (who had slain his father) in Moray, and next he killed two of Sweyn's men who had assisted in the burning of Thorbiorn's relative, Frakok, or Frakark, in Kildonan. Jarl Ragnvald with difficulty reconciles Thorbiorn and Sweyn, and they start for a joint raid. Soon, however, they squabble over the spoils, and Thorbiorn puts his wife Ingirid, Sweyn's sister, away, a deed that reopened their feud.[21] For a series of robberies in Caithness, Sweyn is besieged by Jarl Ragnvald in Lambaborg, now known as Freswick Castle, but escapes by swimming in his armour under the cliffs and landing in Caithness, whence he passed southwards through Sutherland to Scotland and Edinburgh, where King David I received him with honour, and reconciled him with Jarl Ragnvald.[22] In 1148, Ragnvald decided to visit King Ingi in Norway, taking Harold Maddadson, then a boy of fifteen, with him.[23] There he meets Eindridi, who had been long in Micklegarth, as Constantinople was then called by the Norse, probably in the Emperor's service as one of the Varangian Guard; and ships are built for a voyage to the East. But both he and Harold are wrecked in "The Help" and "The Arrow," at Gulberwick, south of Lerwick, on the Shetland coast, all on board, however, being saved, and Ragnvald, as usual, making verses and fun of it all, and of many other things. At last in 1150 Ragnvald's and Eindridi's ships are "boun"[24] for their eastern cruise, Eindridi, however, being wrecked off Shetland. But he gets another ship, and, in 1151, they set sail for the East, William, the bishop of Orkney, commanding one vessel. Passing down the east coast of England and through the Channel to France, they reach Bilbao[25] in Spain, where Ragnvald lands, and refuses to marry Queen Ermengarde. Afterwards he rounds Galicia, where Eindridi's treachery robs them of spoil in taking Godfrey's castle, beats through Niorfa Sound (the Straits of Gibraltar); is deserted by Eindridi, sails along Sarkland (Barbary), captures the Saracen ship Dromund, and burns her, sells the prisoners in Barbary, but releases their prince, coasts along Crete, lands at Acre, and bathes in Jordan on St. Lawrence's Day, the 10th of August 1152. After a visit to Jerusalem they come at last to Constantinople, where the Varangian Guard heartily welcome them, although Eindridi, who has arrived there before him, tries to set everyone against them; and Ragnvald finally returns to Bulgaria and Apulia and Rome, and thence overland to Denmark and Norway.[26]
