According to theGesta Danorum,Alfhild,[a] daughter of theGeatish kingSiward, was ashieldmaiden who had her own fleet oflongships with crews of young female pirates and raided along the coasts of the Baltic Sea.
As a young princess, Alfhild's chamber was guarded by a lizard and a snake, which scared away unworthy suitors. ADanish prince namedAlf, also of Geatish descent, came toGeatland and defeated the animal guards. But Alfhild, advised by her mother, fled from Alf dressed as a man, and she became a shield maiden.
Alf and hisScanian comrade, Borgar, together with their Danish sea-warriors, searched for and eventually found Alfhild and her fleet by the coast of southern Finland. After some deadly fighting aboard the ships, Alfhild's helmet was knocked off, and she was recognised. Alf and Borgar ordered their men to stop fighting, and Alf embraced Alfhild, happy to finally have found her. She then decided to lay off her warrior clothes and follow Alf to Denmark, where they got married.
Some years later, in a war fought against a revolting Danish clan, Alf and his brothers and their father kingSigar were killed. Only Alf's and Alfhild's daughter Gurid had survived of the royal family. After being queen for a while, Gurid married one of Borgar's sons,Halfdan, and they had a son named Harald, who became the new king of Denmark.
According to the details in the saga, this would have taken place in the 5th century.
