Conradin was captured at Torre Astura. Most of his retainers were summarily executed, but Conradin and his friend, Frederick I, Margrave of Baden, were brought to trial for robbery and treason in Naples. They were sentenced to death and beheaded on 29October. Conrad of Antioch was Conradin's only partisan to be released, but only after his wife threatened to execute the Guelph lords she held captive in her castle. The Ghibelline noblemen of the Regno fled to the court of Peter III of Aragon, who had married Manfred's daughter, Constance.
