Equivalents in other languages

Origin: A cartridge is brûlée (burned) when it is fired, because the powder inside burns. Firing your last rounds leaves you nothing to defend yourself with, so the phrase means a final, desperate effort, or one's last arguments. The image had a famous real counterpart: at Bazeilles in 1870, during the Franco-Prussian War, French marine infantry held a house until their ammunition ran out, a scene Alphonse de Neuville painted in 1873 as Les Dernières Cartouches. Whether that episode fixed the phrase is not documented.
