As soon as Fribourg had capitulated the general confided to Colonel Rilliet the care of occupying the military cantonments and watching the entrance of Valais. He himself hastened to Aarau, to prepare for the investment of Lucerne. Two rivers, the Emme and the Reuss, protected this town. The bridges on these rivers had been broken or fortified. The ground on which it was foreseen that the most serious engagements would be delivered was the labyrinth which stretches from the Reuss to the Lake of Zug; bristling with wooded hills, where passage had been stopped by barricades and mines had been laid in the defiles. It was necessary to attack these strong positions, because they served as a link between Schwyz and Lucerne, and success on this point was decisive, whilst elsewhere it was not so. The leader whom the five cantons had put in charge of their militia, Ulrich de Salis-Soglio, understood this, and went to these places. The forces he could dispose of were some twenty thousand regulars and a similar body of the _Landsturm_. Salis had learned warfare in fighting Napoleon. A sincere Protestant, he had nevertheless devoted himself to a cause which had his political sympathies, but of which he despaired. A resolution being taken to force his entrenchments, Dufour set five divisions of his army on the march from the various points they occupied, giving them Lucerne as object. Ochsenbein’s reserves went down the Emme valley, overcoming a lively resistance. The Burkhard and Donatz divisions approached the Emme and the Reuss between the bridges of Wolhusen and Gislikon, at the same time that colonels Ziegler and Gmur at the head of some odd thousands of men attacked Salis in his intrenched camps. Ziegler mastered the Gislikon bridge and the Honau defiles. Gmur, after having received on his march the submission of Zug, scaled the heights of Meyers Kappel. Everything made for success. Victory was hotly disputed, but the Schwyzers were in the end thrown back towards Immensee, whence they fell back on Art and Goldau. Troops from the other cantons turned to Lucerne. The separation of Schwyz with its allies was accomplished. On every hand the federal troops marched simultaneously on that capital. The gates were opened to them by a convention, and on the 24th of November Dufour made his entry. On the following days the Waldstätte and the Valais made their submission. Twenty-five days after the decree of execution the task of the army was complete--the Sonderbund no longer existed.[d] [Sidenote: [1848-1874 A.D.]] The diet now debated the draft constitution drawn up by Kern of Thurgau and Druey of Vaud, which in the summer of 1848 was accepted by fifteen and a half cantons, the minority consisting of the three forest cantons, Valais, Zug, Ticino, and Appenzell (Tuner Rhodes), and it was proclaimed on September 12th.
