The role of the Enemy Captain should be played by a Bass chantante. The scene of the first act is laid in the mill of Father Merlier, shortly before the outbreak of the war of 1870-71. Old Merlier has become reconciled to the match, although at first he was strongly oppossed to it. He indulges in pleasant speculation as to the prospective new management of the mill by the young couple. Swarms of guests are arriving, and all of them give joy to the lovers.
Dancing is begun, and toasts to the happy couple are being proposed when a drum is heard.
It is officially declared that war has commenced, whereupon the guests disperse in affright. The second act happens byu one month thereafter. It is the very day when the wedding of Francehtte and Dominic was to be celebrated, but instead fighting is going on around the mill. A detachment of French soldiers have occupied the mill, and the Prussians are attacking it from without. Merlier, the miller, has been wounded while defending his homestead.
