In London, Saint-Georges stayed with fencing masters Domenico Angelo and Henry, his son, whom he knew as an apprentice from early years in Paris. They arranged exhibition matches for him, including one at Carlton House, before the Prince of Wales. After sparring with him, "carte" and "tierce", the prince matched Saint-Georges with several renowned masters. One included "La Chevalière" D'Éon, aged 59, in a voluminous black dress. A painting by Abbé Alexandre-Auguste Robineau, violinist-composer and painter, showed the Prince and his entourage watching "Mlle" D'Éon score a hit on Saint-Georges, giving rise to rumors that the Frenchman allowed it out of gallantry for a lady. But, as Saint-Georges had fenced with dragoon Captain d'Éon in Paris, he probably was deferring to his age. Saint-Georges played one of his concertos at the Anacreontic Society. He also delivered Brissot's request to the abolitionists MPs William Wilberforce, John Wilkes, and the Reverend Thomas Clarkson. Before Saint-Georges left England, Mather Brown painted his portrait. Asked by Mrs Angelo if it was a true likeness, Saint-Georges replied: "Alas, Madame it is frightfully so."
