After this king Sigurd sailed with his fleet to Lisbon, which is a great city in Spain, half Christian and half heathen; for there lies the division between Christian Spain and heathen Spain[109], and all the districts which lie west of the city are occupied by heathens. There king Sigurd had his third battle with the heathens, and gained the victory, and with it a great booty. So says Halldor Skualldre:— "The son of kings on Lisbon's plains A third and bloody battle gains. He and his Norsemen boldly land, Running their stout ships on the strand." Then king Sigurd sailed westwards along heathen Spain, and brought up at a town called Alkassi[110]; and here he had his fourth battle with the heathens, and took the town, and killed so many people that the town was left empty. They got there also immense booty. So says Halldor Skualldre:— "A fourth great battle, I am told, Our Norse king and his people hold At Alkassi; and here again The victory fell to our Norsemen." And also this verse:— "I heard that through the town he went, And heathen widows' wild lament Resounded in the empty halls; For every townsman flies or falls." King Sigurd then proceeded on his voyage, and came to Nörfa Sound[111]; and in the Sound he was met by a large viking force, and the king gave them battle: and this was his fifth engagement with heathens since the time he left Norway. So says Halldor Skualldre:— "Ye moistened your dry swords with blood, As through Niorfa Sound ye stood: The screaming raven got a feast, As ye sailed onward to the East."
