The September Massacres in 1792, and the execution of Louis XVI in January 1793, firmly ended British support for the revolution, and rendered Williams' further publication risky. To avoid arrest in France for her criticisms of the Jacobins, in 1793 Williams published the third and fourth volumes of her "Letters" anonymously. Williams' authorship was an open secret, and she was explicitly identified by reviewers, as were the two men who contributed additional letters to the volume. This volume was not warmly received in England, and Williams' political positions were seen as too extreme in England, even as she was endangered for being too moderate in France. Williams was the subject of a book-length rebuttal by Laetitia Matilda Hawkins. In Hawkins' "Letters on the Female Mind, Its Powers and Pursuits. Addressed to Miss H. M. Williams, with Particular Reference to Her Letters from France" (1793), Hawkins argued that women were unfit for politics, and that poetry was a more appropriate sphere for the expression of sensibility.
