In 1428, Zawisza, with his retinue as a commander of a light cavalry banner of 500 horsemen, joined the forces of Sigismund in the king's war against the Ottoman Turks. During that disastrous campaign he fought them at the Siege of Golubac on the Danube in modern-day Serbia. Sigismund's army was defeated and had to retreat across the Danube, with only a few boats to ferry the troops over to safety. Zawisza's banner was guarding the retreating army. Being a man of importance, he was personally sent for by King Sigismund. Disheartened by the king's apparent cowardice, he allegedly refused to retreat, saying, "There is no boat big enough to lift my honour." He was either killed in combat at Golubac or executed in Ottoman captivity.
