There are still no batteries for the wireless radio underneath the bed of René's mother-in-law, so Michelle's newest harebrained scheme is to have René and Yvette powering it with the generator from a bicycle until the stolen batteries from a German miniature submarine are delivered. The Lieutenant has finished copying the paintings (The Fallen Madonna and the Van Gogh) and delivers them as sausages. Numerous other sausages also arrive: real ones from Captain Bertorelli, submarine batteries from Leclerc, and explosives from Officer Crabtree, and soon they're all mixed up in the German officers' trousers!
