The conflicts culminated in 1474, after duke Sigismund of Austria had concluded a peace agreement with the confederates in Constance (later called the "Ewige Richtung"). The confederates, united with the Alsatian cities and Sigismund in an "anti-burgundian league", conquered part of the Burgundian Jura (Franche-Comté), and the next year, Bernese forces conquered and ravaged the Vaud, which belonged to the Duchy of Savoy, which in turn was allied with Charles the Bold. The "Sieben Zenden", with the help of Bernese and other confederate forces, drove the Savoyards out of the lower Valais after a victory in the Battle on the Planta in November 1475. In 1476, Charles retaliated and marched to Grandson with his army, but suffered three devastating defeats in a row, first in the Battle of Grandson, then in the Battle of Murten, until he was killed in the Battle of Nancy in 1477, where the confederates fought alongside an army of René II, Duke of Lorraine. There is a proverbial saying in Switzerland summarizing these events as ""Bi Grandson s'Guet, bi Murte de Muet, bi Nancy s'Bluet" (hät de Karl de Küeni verloore)" ("[Charles the Bold lost] his goods at Grandson, his boldness at Murten and his blood at Nancy").
