William fought in France as an ally of the English. (He was the brother-in-law of Edward III.) He went on crusade against the Saracens and the Lithuanians. He besieged Utrecht, because his one-time favourite bishop John van Arkel of Utrecht had turned against him. He died at Warns, near Stavoren, during one of the battles of Warns against the Frisians in 1345.

William was succeeded by his sister, who was married to emperor Louis IV. Hainaut, Holland and Zeeland became a part of the imperial crown domains.
