To prevent a rescue attempt by the Duke of Lennox's soldiers, the Earl of Mar stationed an armed force at Kinross to break their march north. The Earl of Arran's brother, William Stewart reached Ruthven and fought the raiders, lost two fingers and was captured. Arran himself arrived and was captured. The Ruthven lords presented the King with a lengthy "supplication" explaining the motives of their surprise action, dated 23 August. Some sources including the letters of Robert Bowes, an English diplomat sent to Scotland after the event, state the King was captured at Ruthven Castle on 23 August.
