King Halfdan gathered more forces and met Hysing and Helsing at Eith by Eyi where the two were slain and their brother Haki took flight. Halfdan took over Vingilmork and Haki fled to Alfheim.
After King Halfdan died, King Gandolf and others made incursions into King Harald Fairhair's realm and son Haki proceeded into Westfold with 300-360 men while King Gandalf remained in Londir ready to assist in a battle. King Haki was slain in the ensuing battle at Haka Dale, and King Harald then chased King Gandolf back to his own kingdom. In a later battle King Harald's forces killed King Gandolf and took over lands as far south as the Glomma River.
