Burgundian Wars - The Conflict

The Conflict

Initially in 1469, Duke Sigismund of Habsburg of Austria assigned his possessions in the Alsace as a fiefdom to the Duke of Burgundy, Charles the Bold, to have them protected better against the expansion of the Eidgenossen (or Old Swiss Confederacy). Charles' involvement west of the Rhine gave him no reason to attack the confederates as Sigismund had wanted, but his embargo politics against the cities of Basel, Strasbourg, and Mulhouse, directed by his reeve Peter von Hagenbach, prompted these to turn to Bern for help. Charles' expansionist strategy suffered a first setback in his politics when his attack on the Archbishopric of Cologne failed after the unsuccessful Siege of Neuss (1473–1474).

In a second phase, Sigismund sought to achieve a peace agreement with the Swiss confederates, which eventually was concluded in Konstanz in 1474 (later called the Ewige Richtung). He wanted to buy back his Alsace possessions from Charles, which the latter refused. Shortly afterwards, von Hagenbach was captured and executed by decapitation in Alsace, and the Swiss, united with the Alsace cities and Sigismund of Habsburg in an "anti-Burgundian league", conquered part of the Burgundian Jura (Franche-Comté) when they won the Battle of Héricourt in November 1474. The next year, Bernese forces conquered and ravaged Vaud, which belonged to the Duchy of Savoy, who was allied with Charles the Bold. In the Valais, the independent republics of 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, which belonged to Pierre de Romont of Savoy, but which had recently been taken by the Swiss, where he had the garrison hanged or drowned in the lake despite their capitulation. When the Swiss confederate forces arrived a few days later, he was defeated in the Battle of Grandson, and he was forced to flee the battlefield, leaving behind his artillery and many provisions and valuables. Having rallied a new army, he was dealt a devastating blow by the confederates in the Battle of Morat. Charles the Bold fell in the Battle of Nancy in 1477, where the Swiss fought alongside an army of René II, Duke of Lorraine.
