At Sempach in 1386 the Confederates again beat the Habsburgs, and this time Duke Leopold III himself was killed on the field. Legend credits the sacrifice of Arnold Winkelried, said to have gathered an armful of enemy pikes into his own body to open a gap for his comrades to pour through. The victory broke Habsburg power in the region, drew more communities into the alliance, and sealed the fearsome reputation of Swiss pike-and-halberd infantry that would dominate European battlefields for a century.
