Despite being vastly outnumbered, forces of the Old Swiss Confederacy defeated an Austrian army at the Battle of Näfels.

The Old Swiss Confederacy, also known as Switzerland or the Swiss Confederacy, was a loose confederation of independent small states, initially within the Holy Roman Empire. It is the precursor of the modern state of Switzerland.

The Battle of Näfels was fought on 9 April 1388 between the Swiss canton of Glarus, supported by its allies of the Old Swiss Confederation, and the Duchy of Austria ruled by the House of Habsburg. It was a decisive victory for Glarus and led to its independence from Habsburg rule. The battle was the last of the Swiss-Austrian conflicts that stretched through most of the 14th century.
