On 19th of June 1306 The Battle of Methven took place which saw the defeat of the newly crowned King of Scots, Robert the Bruce.
Robert Bruce had been crowned on 25th of March 1306.
Bruce and his men were camped just outside of Perth. In a surprise attack the forces of Edward I of England under the command of Aymer de Vallence swarmed over the camp as it was still being set up.
It was a shambles of close hand fighting with both King Robert and de Vallence being unhorsed.
The King barely managed to escape but many were killed and captured.
The confusion of the fighting is captured in the Netflix film The Outlaw King.
