and Switzerland. While on the Continent, he translated the First Helvetic Confession into English. He returned to Scotland in 1544, but the timing of his return was unfortunate. In December 1543, James Hamilton, Duke of Châtellerault, the appointed regent for the infant Mary, Queen of Scots, had decided with the Queen Mother, Mary of Guise, and Cardinal David Beaton to persecute the Protestant sect that had taken root in Scotland. Wishart travelled throughout Scotland preaching in favour of the Reformation, and when he arrived in East Lothian, Knox became one of his closest associates. Knox acted as his bodyguard, bearing a two-handed sword in order to defend him. In December 1545, Wishart was seized on Beaton's orders by the Earl of Bothwell and taken to the Castle of St Andrews. Knox was present on the night of Wishart's arrest and was prepared to follow him into captivity, but Wishart persuaded him against this course saying, "Nay, return to your bairns [children] and God bless you. One is sufficient for a sacrifice." Wishart was subsequently prosecuted by Beaton's Public Accuser of Heretics, Archdeacon John Lauder. On 1 March 1546, he was burnt at the stake in the presence of Beaton. Knox had avoided being arrested by Lord Bothwell through Wishart's advice to return to tutoring. He took shelter with Douglas in Longniddry. Several months later he was still in charge of the pupils, the sons of Douglas and Cockburn, who wearied of moving from place to place while being pursued. He toyed with the idea of fleeing to Germany and taking his pupils with him. While Knox remained a fugitive, Beaton was murdered on 29 May 1546, within his residence, the Castle of St Andrews, by a gang of five persons in revenge for Wishart's execution. The assassins seized the castle and eventually their families and friends took refuge with them, about a hundred and fifty men in all. Among their friends was Henry Balnaves, a former secretary of state in the government, who negotiated with England for the financial support of the rebels. Douglas and Cockburn suggested to Knox to take their sons to the relative safety of the castle to continue their instruction in reformed doctrine, and Knox arrived at the castle on 10 April 1547. Knox's powers as a preacher came to the attention of the chaplain of the garrison, John Rough. While Rough was preaching in the
