Act I. Barracks of St. Honoré. Under penalty of death the Swiss
soldiers have been forbidden to sing their native songs especially the Kuhreigen or "Ranz des Vaches," because songs of their native land always awakened homesickness and had led to desertions. But a quarrel between _Primus Thallus_, of the Swiss, and _Favart_, of the Chasseurs, excites the Swiss and they sing "In the fort at Strassburg" (Zu Strassburg auf der Schanz) the song of the Swiss who became a deserter through homesickness, the song which was forbidden by such a severe decree, especially because it introduced the Kuhreigen or "Ranz des Vaches." Then _Favart_ believed the moment had come to be able to avenge himself. He quickly called an officer to hear the forbidden song. The officer first wants to arrest all the Swiss, but _Primus Thallus_ takes all the blame on himself; he is glad to prevent the others being imprisoned.
