One of these murderers of Jarl Rognwald quietly set himself in Rognwald’s place, the other making for Orkney to serve Turf-Einar in like fashion. Turf-Einar, taken by surprise, fled to the mainland; but returned, days or perhaps weeks after, ready for battle, fought with Halfdan, put his party to flight, and at next morning’s light searched the island and slew all the men he found. As to Halfdan Long-leg himself, in fierce memory of his own murdered father, Turf-Einar “cut an eagle on his back,” that is to say, hewed the ribs from each side of the spine and turned them out like the wings of a spread-eagle: a mode of Norse vengeance fashionable at that time in extremely aggravated cases!
