The Jet-Propelled Mother-in-Law

The Germans arrest René, and the Colonel demands an explanation for the knockwursts with explosives in them. After a small lie, René is sent home with around a dozen knockwursts to hang in his kitchen.
Meanwhile, the British have sent a spy camera with which the Resistance should be able to photograph the plans for the German invasion of Great Britain, but the camera landed in the vineyard of Monsieur Alphonse, and since the Germans commandeered the vineyard, the Resistance cannot go and look for the camera. This problem is solved when the General orders every peasant in Nouvion to work on the vineyard, which also leaves room for some assassination attempts on the General's life.
