Swiss Confederacy

The Battle of St. Jakob an der Birs was fought between the Old Swiss Confederacy and French (mostly Armagnac) mercenaries, on the banks of the river Birs. The battle took place on 26 August 1444 and was part of the Old Zürich War. The site of the battle was near Münchenstein, Switzerland, just above 1 km outside the city walls of Basel, today within Basel's St-Alban district.

In 1443, the seven cantons of the Old Swiss Confederacy invaded the canton of Zürich and besieged the city. Zürich had made an alliance with Frederick III, Holy Roman Emperor, who now appealed to Charles VII of France to send an army to relieve the siege.
