The chief of Clan Donald, Lord of the Isles, had resigned the title of Earl of Ross to the king in 1477. After this the province of Ross was constantly invaded by the MacDonald islanders. As a result, a battle was fought between the Clan Donald islanders, led by Gillespick MacDonald against the Clan MacKenzie. The MacDonald islanders were defeated with many men being drowned in the River Conon.
