fool. Simplicius finds himself facing arrest under the orders of the Sergeant-major. Arnim and Melchior, still imprisoned, reach an understanding. Melchior agrees to give up his claim to Hildegarde on condition that the family fortune tied up in the marriage deal be handed over to him. Arnim agrees. Before being able to tell Hildegarde the good news, General von Vliessen receives a new order from Vienna: a wild young man named Simplicius must be found. Whoever should find him is honour-bound to treat him with respect as he is none other than the son of Baron von Grübben. The General immediately promotes Simplicius to the rank of lieutenant and orders him to marry Hildegarde. Arnim is overjoyed at meeting his long-lost brother again. Simplicius agrees to be married but is confused, especially as Tilly now demands to know his feelings towards her. Schnapslotte offers Tilly more homely advice as Simplicius and Tilly talk of love.
