In 1655 the canton of Schwyz began prosecuting those Protestant families who had remained in Schwyz. Some were turned in to the inquisition in Milan, some were beheaded, and the property of those who fled to Protestant Zürich was confiscated. Zürich demanded compensation for this property. Schwyz demanded the return of the refugees. Zürich urged Bern to declare war on the Catholic cantons (Schwyz and its allies Uri, Unterwalden, Zug and Lucerne). Zürich's forces laid a fruitless siege of Rapperswil, while Catholic forces separated Zürich from Bern, beating the Bernese at the First Battle of Villmergen on 24 January 1656. Hostilities ceased on 20 February and the treaty of Villmergen of 7 March reinstalled the status quo preceding the outbreak of hostilities, wherein each canton could specify the religion of all its residents. However, religious tensions continued to rise. When the abbot of St. Gallen proposed to build a "Catholic" road from Schwyz to Austria that would cut off the Protestant part of Glarus from its support in Zürich, the Protestant cantons declared war on the Abbot. After the Protestant victory at the Second Battle of Villmergen, religious equality was established in the Confederation.
