Dumbarton Castle

From Wikipedia we find this reference to Sir John in reference to Dumbarton Castle: "In 1425 the castle was attacked by James the Fat, youngest son of Murdoch Stewart, Duke of Albany, who had been imprisoned by King James I of Scotland on charges of treason. James the Fat became a rallying point for enemies of the King, and raised a large rebellion against the crown. He marched on the town of Dumbarton and burned it, but was unable to take the castle, whose defender John Colquhoun successfully held out against James' [the Fat's] men."
