A legend from the battle tells of Arnold von Winkelried, a Swiss soldier who, in a self-sacrificial act, seized a number of enemy pikes and formed a breach in the Austrian lines, allowing his compatriots to exploit the break in the formidable Habsburg defense.

This battle is celebrated as a symbol of Swiss unity and resilience against external domination, contributing to the eventual establishment of Switzerland as an independent confederation of states.

Sempach remains a critical moment in Swiss national history, highlighting the efficacy of infantry against cavalry in medieval warfare and symbolizing the power of a united front against an imposing adversary.
