The Battle of the North Inch was a staged battle between the Clan Chattan and the "Clan Quhele" in September 1396. Thirty men were selected to represent each side in front of spectators, including King Robert III of Scotland and his court, on land that is now the North Inch park in Perth, Scotland.
The Clan Chattan 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 whom 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 confederation of Clan Chattan.
