The wall was breached on the north east side of the castle where it is highest and therefore presumed to be the least well guarded. The eastern peak of the rock (The Beak) was quickly gained, and the cannon there was captured and turned on the garrison, who attempted very little resistance, preferring to escape rather than fight back. The castle governor (Fleming) managed to escape through the postern gate which opened onto the River Clyde and reached Argyllshire. Key supporters of Queen Mary found within the castle included de Verac, the French ambassador, who was allowed to go free, but was subsequently caught aiding the Queen's supporters in Edinburgh Castle. John Hamilton, Archbishop of St Andrews was also found in the castle wearing items of armour (a mail shirt and helmet). The wife of the governor (Lady Fleming) was also detained, but was permitted to go free with her possessions. Hamilton was hanged within a matter of days at Stirling Castle. As important as the arrest of key people was the capture of documents, including some implicating Queen Mary with Thomas Howard, 4th Duke of Norfolk and the Ridolfi plot.
