"Malbrough s'en va-t-en guerre", also known as "Mort et convoi de l'invincible Malbrough", is a folk song in French.

Geneviève Poitrine, known as Madame Poitrine, was a wet nurse of the Dauphin of France, Louis Joseph, son of King Louis XVI and Queen Marie Antoinette. Poitrine was retrospectively accused of transmitting tuberculosis to the infant prince, thus inadvertently causing his death, aged seven years; this meant that his younger brother Louis Charles became heir apparent. The word poitrine translates to "chest" or "bosom", and her married name of Madame Poitrine was remarked upon by contemporaries as being appropriate for her duties.
