 In 1546, George Wishart, a preacher who had come under the influence of Swiss reformer Huldrych Zwingli, was arrested and burnt at the stake in St. Andrews on the orders of Cardinal Beaton.Wishart's supporters, who included a number of Fife lairds, assassinated Beaton soon after and seized St. Andrews Castle, which they held for a year while under siege, before they were defeated with the help of French forces.The survivors, including chaplain John Knox, were condemned to be galley slaves, helping to create resentment of the French and martyrs for the Protestant cause.
