Sweyn II of Denmark
In 1062, on August 9, Skjalm Hvide together with the King Sweyn II of Denmark (c. 1019 – 28 April 1076; reigned in 1047–1076) fought in the Battle of Niså, a naval battle off the coast of Halland, in what today is southwestern Sweden. The enemy were the forces of the Norwegian king Harald Hardrada, who had claimed the Danish throne since 1047, and had launched raids into Denmark ever since then.
