Physically Charlotte developed early, and at fifteen she was a young woman.
‘She is grown excessively,’ wrote Lady Charlotte Bury, ‘and has all the fulness of a person of five-and-twenty.’ This critical lady-in-waiting considered that the young princess was neither graceful nor elegant, but had to admit that the she had ‘a peculiar air’. ‘The Princess Charlotte,’ she continues, ‘is above the middle height, extremely spread for her age; her bosom full, but finely shaped; her shoulders large, and her whole person voluptuous.’ But Lady Charlotte predicts unkindly that ‘without much care and exercise she will shortly lose all beauty in fat and clumsiness’.
The Princess was well aware of this danger: from her father and several of her aunts and uncles she inherited a tendency to stoutness, which she knew that she must fight by taking exercise; but she was lethargic, particularly in the winter, when she felt the cold excessively and hated the thought of going out. She was now spending part of the year at Windsor, and the rest of her time at Warwick House, a small building standing to the east of Carlton House, with a gate leading into the Prince’s grounds. It was shabby and isolated: ‘nothing,’ wrote Miss Cornelia Knight, ‘could more perfectly resemble a convent than this residence; but it was a seat of happiness to Princess Charlotte compared with the Lower Lodge at Windsor, and she was anxiously desirous to remain in Town as much as possible.’
At Windsor when the weather was bad, there was nothing whatsoever to do. She disliked the Queen intensely, believing at this stage that her grandmother was plotting against her; neither could she be sure of her ground with her older aunts, and she found the monotonous life, full of petty intrigue, quite intolerable. She must also have been haunted by the knowledge that her grandfather, whom she loved, was there, in the Castle, shut away from his family, rigorously hidden from sight (but not always from sound). She heard the discreet bulletins given by the numerous tiptoeing obsequious doctors: ‘not so well today as he was yesterday’, ‘the King was composed throughout the day’, ‘the King had had three hours’ sleep and was composed’, or ‘by no means as well as he was’. She learned that it was, among the family, a subject to be avoided; slowly she accepted the cruel truth, that her grandfather was hopelessly out of his mind-and she would never see him again.’
