In the late 15th century the Clan Mackay and Clan Ross had long been at feud. This resulted in the Battle of Tarbat in 1486 where the Mackays were defeated by the Rosses and the Mackay chief was killed. This was followed by the Battle of Aldy Charrish where the Rosses were defeated by the Mackays and the Ross chief was killed along with many of his clan. According to 17th-century historian Sir Robert Gordon, who was a younger son of Alexander Gordon, 12th Earl of Sutherland, the Clan Sutherland joined the side of the Clan Mackay at this battle. However 19th-century historian Angus Mackay disputes the Sutherland's presence at the battle stating that it would be unlikely that the Earl of Sutherland at the time would have assisted against the Rosses as he was married to a daughter of the Ross chief of Balnagowan, and also that the feudal superiority of the Sutherlands over the Mackays "nowhere existed save in his own fertile imagination".
