The terrible slaughter among their men had, however, so disgusted the leaders of the colony, that they soon afterwards returned to Greenland; and, but for the ambition of Freydis, the history of the Scandinavian colonies in North America would have ended then and there. Unable to forget her triumph, and eager for yet further distinction, this remarkable woman did not rest until she had organized a new expedition, which, under the leadership of two brothers named Helgi and Finnbogi, set sail in 1011, and, landing in Vinland without molestation from the natives, took possession of the booths erected by their predecessors. All seemed likely to go well, when the overbearing conduct of Freydis, who was not one to shine in the peaceful work of colonization, led to dissensions among the explorers. By a crafty artifice she managed to pick a quarrel with the two brothers, and, with the co-operation of her husband, Thorvard――who, though naturally a mild and inoffensive man, appears to have been entirely under the control of his stronger-minded wife――she succeeded in effecting their massacre, and that of all who were inimical to her supremacy. The survivors, terror-struck by the fate of their companions, yielded without a struggle to the rule of Freydis, who, first binding them all by an oath never to tell of her conduct at home, set them at work to cut timber and collect the curiosities and valuables of the country. Then, when she had acquired enough to insure her wealth for the remainder of her life, she embarked for Greenland with the little remnant of the original party. The Icelandic sagas, already referred to, tell how the iniquity of Freydis gradually leaked out, and how, though she herself escaped unpunished, her sins were visited upon her children. With her return home the attempts at American colonization by the Northmen appear to have ceased, but tradition tells of many a trip by contemporary adventurers of other nationalities; for, between the fitful excursions from Greenland――which, as we have seen, left no real or permanent impress on the people or districts visited――and the well-organized expedition of modern times, we hear of Arab sailors of the 12th century having sighted land in the unknown Western Ocean, graphically called, from its real and imaginary horrors, the Sea of Darkness; and of a voyage made in 1170 by Madoc, son of the Prince of North Wales, who, after sailing for many weeks away from his native land, came to a country, supposed to have been the modern Virginia, differing in every respect from any European land.
