In the height of the battle Earl Haakon disappeared. As the legends tell he went ashore with his youngest son Erling, whom he sacrificed to the heathen gods to win their aid in the battle. Hardly had he done this deed of blood when a dense black cloud arose and a violent hail-storm broke over the ships, the hail-stones weighing each two ounces and beating so fiercely in the faces of the Jomsvikings as nearly to blind them. Some say that the Valkyries, the daughters of Odin, were seen in the prow of the earl's ship, filling the air with their death-dealing arrows. Despite the storm and the supernatural terrors that they conjured up, the Jomsvikings continued to fight, though their decks were slippery with blood and melting hail. Only one coward appeared among them, their chief Earl Sigvalde, who suddenly turned his ship and fled. When Vagn Aakesson, the most daring of the Jomsvikings, saw this recreant act he was frantic with rage. "You ill-born hound," he cried, "why do you fly and leave your men in the lurch? Shame on you, and may shame cling to you to your death!" A spear hurtled from his hand and pierced the man at the helm, where Sigvalde had stood a moment before. But the ship of the dastard earl kept on and a general panic succeeded, all the ships in the fleeing earl's line following his standard. Only Vagn Aakesson and Bue the Big were left to keep up the fight. Yet they kept it up in a way to win them fame. When Earl Haakon's ship drew up beside that of Bue, two of the viking champions, Haavard the Hewer and Aslak Rock-skull, leaped on deck and made terrible havoc. In the end an Icelander picked up an anvil that was used to sharpen their spears and hurled it at Aslak, splitting his skull, while Haavard had both legs cut off. Yet the indomitable viking fought on, standing on his knees. The onset of the Jomsvikings was so terrific in this last fierce fight that the earl's men gave back, and might have been all slain had not his son Erik boarded Bue's ship at this crisis and made an irresistible charge. A terrible cut across the face severed Bue's nose. "Now," he cried, "the Danish maidens will kiss me no more." Seeing that all was at an end, he seized two chests of gold to prevent their capture by the victors, and sprang with them into the sea, shouting: "Overboard all Bue's men!" On Vagn's ship a similar fierce fight was taking place, ending only when all but thirty of the vikings were slain. Then a savage scene was enacted, one worthy only of those barbarous times. The captives were taken ashore and seated on a long log, their feet bound, their hands free. At the funeral feast in Sigvalde's hall Vagn had boasted that he would kill Thorkill Laiva, one of Erik's chief warriors, and this threatened man was now chosen as executioner.
