Charlotte’s letters to Mercer take on a happier note at this point. ‘I have agreed without any demur or hesitation to see young P. when he comes,’ she wrote on December 8. She had received more accounts of him ‘from those who know him personally’, and felt that he could not, after all, be so bad: for one thing, ‘he is lively & likes fun & amusement’. A print of him was sent to Carlton House, and that evening, at a family party, it was placed upon a chair to be looked at, and ‘Princess Charlotte thought it not ugly,’ wrote Miss Knight.
At this party, attended by the Queen and two princesses, the Regent was ‘mighty busy & good-humoured’, she said. He was wearing a belt studded with rose-diamonds, to which he added a diamond clasp. It had been given to him by the Grand Seigneur of Turkey, he said, with a magnificent scimitar, but he did not greatly car for it. The ladies gathered round him, cooing with admiration, and Ladies Castlereagh and Hertford agreed with Charlotte that the diamonds would make beautiful ornaments; whereupon he undid the clasp, with a heave unwound the glittering thing from his well-corseted paunch, ‘and in the most amiable manner,’ said Charlotte, ‘gave it to me.’ She was in high favour. She dined at Carlton House two evenings in succession, and the Prince, she said, ‘was exceedingly kind & gracious … He has talked to me both days more than he has done for ages’.
On the second evening, December 9, a great many distinguished foreigners were present, including Madame de Staël, for whom Charlotte had a great admiration both as a writer and raconteur. She was accompanied by her husband and daughter, Albertine (good-humoured but silly, said Charlotte), and was ‘very pleasant’. ‘I think nothing could be more brilliant than the appearance of everything,’ wrote Charlotte, who was only just beginning to learn what Carlton House entertainment could be. Her letter to Mercer the next day bubbles with excitement and delight. ‘As to whether I was in beauty last night, I cannot answer,’ she began … ‘except by assuring you that I did not feel out of hea[l]th, or out of humour. Indeed no.’ She had blossomed under the Prince’s kindness, and had felt herself to be a success with his guests. She was happy, and even the news that she was going to Windsor for Christmas did not spoil her happiness.
Four days later, on December 13, her tone is still light-hearted, as she replies to a letter from Mercer, giving a favourable report of the Prince of Orange on his arrival at Plymouth. ‘I really admire the victory a single glimpse of his form has had upon you,’ Charlotte wrote, ‘& give my permission to your being in love with him for my sake according to the old proverb, “Love me, love my dog.”‘
This is quite a startling change of attitude, and shows how strong still was Mercer’s influence. Princess Mary, Sir Henry Halford, any member of ‘Government persons’ and even the Regent himself might try in vain to persuade her to consider the Orange alliance, but a word from Mercer in favour of the Prince, a suggestion that Charlotte should stop opposing the match, was enough to bring about a complete change of attitude. She had already agreed to see him: now she would even try to like him. She had had other good accounts of him – he was adored in the army: not only Lord Wellington, but all his brother officers spoke highly of him. Mercer’s letter had ‘eased me of 100,000 worrys’, she said.
All the same, she had her reservations. She agreed that the match would smooth out some of the problems now facing the Regent ‘with regard to the arrangement of the Netherlands’. Austria was demanding a bigger slice of Holland than had been planned and there was ‘an awkwardness … which requires much delicacy to remove’. The Netherlands rulers, the House of Orange, clearly needed British backing; but Charlotte was determined on one point: however much the young Prince might wish for the support of an English wife, nothing would induce her at any time to leave her native land. ‘As heiress presumptive to the Crown it is certain that I could not quit this country, as Queen of England still less.’ The Prince of Orange, said Charlotte firmly, must visit his frogs solo.’
