There are still no batteries for the wireless radio underneath the bed of Renandeacute;'s mother in law, so Michelle's newest harebrained scheme is to have Renandeacute; and Yvette powering the radio with the generator from a bicycle until the stolen batteries from a German midget submarine are delivered.
The Lieutenant has finished copying the paintings (The Fallen Madonna... and the Van Gogh), and delivers them as sausages. Sausages also come from Captain Bertorelli (real ones), Monsieur LeClerc (submarine batteries), and Officer Crabtree (explosives), and soon they're all mixed up in the German officers pants.
