On the appointment of the Ladies of the Bedchamber to the Queen, Lady Sandwich was justified in her fear, “that the King would still keep in, with Lady Castlemaine.” A great commotion occurred, in the old Palace of Hampton Court. The Queen had never mentioned the favourite’s name; therefore Charles hoped she was ignorant of her rival’s existence; but when the list of the proposed Ladies of the Bedchamber, was submitted to her Majesty, Catherine deliberately pricked out the name of my Lady Castlemaine, which much disturbed her husband. By the King’s command, Lord Clarendon, sorely against his inclination, waited on Her Majesty, to try and induce her to cancel her refusal, but the Queen “was much discontented with her husband,” and declared that rather than submit to the insult, she would desire to return to her own country. Lady Castlemaine through an artifice however, approached her Royal mistress, and kissed her hand; who, on discovering the trick, fell into a swoon, and was carried from the apartment. The King was furious; the Queen for a while appeared inflexible, but Charles gained his point in the end, for after some time had elapsed, Barbara’s appointment was confirmed, and from that time forth, the Queen, by some strange persuasion, or obedience to the King’s orders, treated her rival with familiarity, and confidence; “was,” says Pepys, “merry with her in public, and in private used nobody more friendly.” But then, according to the same authority, “the Queen is a most good lady, and takes all, with the greatest meekness that may be.”
The syren seems indeed to have bewitched every one, Dryden himself did not disdain to write a poem in her honour. On one occasion the Countess had a violent altercation, with “la belle Stewart,” Maid of Honour, who had excited her jealousy, and the King, taking part against her, the imperious lady walked off to her uncle’s at Richmond, whither Charles soon followed her, on pretence of hunting, but really to ask pardon. Not long after, however, Pepys saw her on horseback, with the King, the Queen, Mistress Stewart, etc.; but he thought the King looked coldly on her, “and when she had to ’light, nobody pressed to take her down, but her own gentleman, and she looked, though handsome, mighty out of humour, and had a yellow plume in her hat.” A report reached the Queen’s ears, that Barbara had turned Papist, but though a zealot in her religion, Catherine “did not much like it, as she did not believe it was done for conscience sake.” Perhaps her Majesty agreed, with the learned Divine who said that “if the Church of Rome had got no more by Lady Castlemaine, than the Church of England had lost, the matter was not much.”
