Knox's work in the castle and town of St. Andrews was interrupted by the arrival of a French fleet (July 1547), which battered the walls with artillery until the castle was compelled to surrender. He and all the inmates were carried over to France. They had secured as terms of surrender that their lives should be spared; that they should be safely transported to France; and that if they could not accept the terms there offered to them by the French King, they should be allowed to depart to any country they might select for their sojourn, save Scotland. It was not the custom, however, for French kings to keep promises made to heretics, and Knox and his companions were made galley-slaves. For nineteen months he had to endure this living death, which for long drawn out torture can only be compared with what the Christians of the earliest centuries had to suffer when they were condemned to the mines. He had to sit chained with four or six others to the rowing benches, which were set at right angles to the side of the ship, without change of posture by day, and compelled to sleep, still chained, under the benches by night; exposed to the elements day and night alike; enduring the lash of the overseer, who paced up and down the gangway which ran between the two lines of benches; feeding on the insufficient meals of coarse biscuit and porridge of oil and beans; chained along with the vilest malefactors. The French Papists had invented this method of treating all who differed from them in religious matters. It could scarcely make Knox the more tolerant of French policy or of the French religion. He seldom refers to this terrible experience. He dismisses it with:
"How long I continewed prisoneir, what torment I susteaned in the galaies, and what war the sobbes of my harte, is now no time to receat: This onlie I can nocht conceall, which mo than one have hard me say, when the body was far absent from Scotland, that my assured houp was, in oppin audience, to preache in Sanctandrois befoir I depairted this lyeff."[290]
The prisoners were released from the galleys through the instrumentality of the English Government in the early months of 1549, and Knox reached England by the 7th of April. It was there that he began his real work as a preacher of the Reformation. He spent nearly five years as minister at Berwick, at Newcastle, and in London. He was twice offered preferment--the vacant bishopric of Rochester in 1552, and the vicarage of All Hallows in Bread St., London, in the beginning of 1553. He refused both, and was actually summoned before the Privy Council to explain why he would not accept preferment.[291] It is probable that he had something to do with the production of _The Book of Common Prayer and Administration of the Sacraments and other Rites and Ceremonies in the Church of England, 1552_, commonly called the _Second Prayer-Book_ of King Edward VI. The rubric explaining kneeling at the partaking of the Holy Supper, or at least one sentence in it, is most probably due to his remonstrances or suggestions.[292] The accession of Mary Tudor to the throne closed his career in England; but he stuck to his work long after his companion preachers had abandoned it. He was in London, and had the courage to rebuke the rejoicings of the crowd at her entry into the capital--a fearless, outspoken man, who could always be depended on for doing what no one else dared.
