The Battle of the North Inch (also known as the Battle of the Clans) was a staged battle between the Chattan Confederation and the "Clan Kay" in September 1396. 30 men were selected to represent each side in front of spectators that included King Robert III of Scotland and his court, on land that is now the North Inch park in Perth, Scotland. The Cattanach killed all but one of their opponents at a cost of 19 deaths on their own side, and were awarded the victory. It is not clear who they were fighting: it may have been their traditional enemies Clan Cameron or it may have been Clan Davidson, in an internal dispute for precedence in the Chattan line of battle in future campaigns against the Camerons.
According to historian Alexander Mackintosh Shaw, Clan Chattan was composed of MacKintoshes, MacPhersons, Davidsons, MacGillivrays and Macbeans, while Marshall's History of Perth states that "it is generally accepted that the Clan Chattan were the MacKintoshes, but, as always happens with the unfortunate, no sept or clan is willing to claim kindred with the Clan Kay". Some historians identify Clan Kay with Clan Cameron, whose feud with the Chattans would last 360 years. More recent historians, however, have suggested that the battle was an internal dispute between two clans from within Clan Chattan over who should take precedence in order of battle. This dispute had almost given the Camerons victory at the Battle of Invernahavon (1370 or 1386).
