In July, 1680, men of the Clan MacIver of Argyll who were a sept of the Clan Campbell apparently joined up with the MacIvers of Caithness in support of Sir John Campbell of Glenorchy and fought against the forces of George Sinclair of Keiss at the Battle of Altimarlach, in a dispute over who had the right to the title and lands of the Earl of Caithness. Campbell won the battle, but Sinclair later turned to the law and was awarded the lands and title as Earl of Caithness. Although the MacIvers only formed a small part of Glenorchy's force, they contributed their full share to its success and, according to tradition, the piper of the clan in Caithness, Finlay MacIver, composed the Great Highland bagpipe tune, "Bodach-na-briogais", which was inspired by the battle. According to Hugh Fraser Campbell and Walter Biggar Blaikie, Glenorchy's piper, Findlay MacIver, had composed at this time the well known piping tune, "The Campbells Are Coming".
