[5, 8] fjórar hríðir ǫrva ‘four blizzards of arrows [BATTLES]’: The ‘four battles’ fought in a single season (lit. ‘winter’) are probably those of Wollin (Jóm), Rügen (Ré), Århus (Áróss) and Lyrskovshede (Hlýrskógsheiðr), all fought in 1043, and the st. seems to have been understood so by Snorri (Bjarni Aðalbjarnarson, ÍF 28). The author of Knýtl, as the context there suggests, thought otherwise. That the victory at Lyrskovshede followed the sacking of Wollin/Jóm is probable (so all but one version of the Icel. annals for 1043, Storm 1888, 17, 108, 317 and 469, with p. 58 as the exception; Schreiner 1930-3, 39 favoured dating Lyrskovshede before Wollin).
