James, the Duke of York, remained still in London. He continued there for two years, during which time his father's affairs went totally to ruin. The unfortunate king, after his armies were all defeated, and his cause was finally given up by his friends, and he had surrendered himself a prisoner to his enemies, was taken from castle to castle, every where strongly guarded and very closely confined. At length, worn down with privations and sufferings, and despairing of all hope of relief, he was taken to London to be tried for his life. James, in the mean time, with his brother, the little Duke of Gloucester, and his sister Elizabeth, were kept in St. James's Palace, as has already been stated, under the care of an officer to whom they had been given in charge. The queen was particularly anxious to have James make his escape. He was older than the others, and in case of the death of Charles, would be, of course, the next heir to the crown. He did, in fact, live till after the close of his brother's reign, and succeeded him, under the title of James the Second. His being thus in the direct line of succession made his father and mother very desirous of effecting his rescue, while the Parliament were strongly desirous, for the same reason, of keeping him safely. His governor received, therefore, a special charge to take the most effectual precautions to prevent his escape, and, for this purpose, not to allow of his having any communication whatever with his parents or his absent friends. The governor took all necessary measures to prevent such intercourse, and, as an additional precaution, made James _promise_ that he would not receive any letter from any person unless it came through him.
