Claim: Princess Charlotte of Wales wrote to her favorite uncle, the Duke of Sussex (the sixth son of King George III, who was known for his liberal views) when she was conveyed to Cranbourne Lodge with orders to never be out of sight of attendants.
Evidence: Princess Charlotte Augusta of Wales (7 January 1796 – 6 November 1817) was the only child of George, Prince of Wales (later King George IV), and his wife, Caroline of Brunswick. Prince Augustus Frederick, Duke of Sussex, KG, KT, GCB, GCH, PRS, FRSA (27 January 1773 – 21 April 1843) was the sixth son and ninth child of King George III and his queen consort, Charlotte of Mecklenburg-Strelitz. He was known for his liberal views, which included reform of Parliament, abolition of the slave trade, Catholic emancipation, and the removal of existing civil restrictions on Jews and dissenters. Charlotte informed the Prince of Orange that if they wed, her mother would have to be welcome in their home—a condition sure to be unacceptable to the Prince Regent. When the Prince of Orange would not agree, Charlotte broke off the engagement. Her father's response was to order that Charlotte remain at her residence at Warwick House (adjacent to Carlton House) until she could be conveyed to Cranbourne Lodge at Windsor, where she would be allowed to see no one except the Queen. Despite an emotional reconciliation with his daughter, the Prince Regent soon had her conveyed to Cranbourne Lodge, where her attendants were under orders never to let her out of their sight. She was able to smuggle a note out to her favourite uncle, Prince Augustus, Duke of Sussex. Despite her isolation, Charlotte found life at Cranbourne Lodge surprisingly agreeable, and slowly became reconciled to her situation.
