Frederick was reached by the news at Melfi, and immediately raised an army to set the matter, while the rebel citizens of Viterbo requested help from Frederick's traditional enemy, the pope. The emperor led the siege personally, but the maneuvers of his troops were unsuccessful, and the defenders were able to set on fire the imperial siege towers. The siege thus resulted in a humiliation for Frederick.[2] Pope Innocent IV, fearing that the event could start a war with the emperor, intervened; his legate, cardinal Otto of San Nicola in Carcere, convinced the rebels to sign a treaty of peace. However, after the signature, they treacherously attacked and massacred the imperial garrison. The pope punished the citizens of Viterbo only with a pecuniary mulct, and retained control of the city in the person of his legate, Ranieri of Viterbo. See also
