Charlotte de Montmorency, echtgenote van Henri II de Bourbon-Condé. “[On 29 November 1609] the prince de Condé eloped to Brussels with his young wife Charlotte. This Charlotte was a marvellously beautiful nymph of fifteen, after whom Henry [IV] had been lusting since January 1609: he had arranged for her to be married to the prince of Condé, a rather lackadaisical young man, in the hope that he, Henry, could the enjoy her favours. This arrangement, which had both its entertaining and its sordid aspects, quite fell through when Condé fled to Brussels. The king was beside himself, and as early as 1 December 1609 publicly remarked that, if the archdukes [Albert of Austria and Isabella of Spain] would not surrender Condé and the princess, he would go to Flanders and fetch them, at the head of 50,000 men. So this new Helen, …, transformed the relatively innocuous controversy over the succession to Jülich-Cleves-Berg into an urgent casus belli. …” (D. Buisseret, Henry IV [Londen 1984], p. 173-174)
