After the battles of Grandson and Murten, both decisive Swiss victories, Vaud was again conquered by the Swiss and lost to Jacques of Savoy. Bern demanded Vaud and threatened Geneva and Savoy. Meanwhile, Duchess Yolande had fallen into the hands of Charles the Bold. King Louis XI intervened in favor of his sister and forced the Swiss to accept an armistice. On 14 April 1476 the Swiss Confederacy and Savoy concluded a peace treaty under the sponsorship of the French King.
