Lady Anne had radical sensibilities[2] and on the Prince succeeding as George IV on 29 January 1820, repeatedly urged Caroline to return and claim her position as Queen Consort of Great Britain.

She crossed to France to meet Caroline at St. Omer, and with Alderman Matthew Wood, a radical former Lord Mayor of London, escorted her back to the capital.

[3] She resumed her position in Caroline's household, accompanying her to her trial for adultery in the House of Lords in August 1820, and remaining almost her sole supporter among ladies of consequence[4] until her acquittal.

[9] The work, which was published anonymously, satirised the main figures involved in what was called "The Delicate Investigation" of the morality and suspected adultery of Caroline of Brunswick.

[13] However a subsequent biographer of Queen Caroline attributes the record of her demeanour and words as she lay dying directly to Hamilton as author of this work.
