Returned in Montefiascone, Ottone lost his powerful ally Urban IV, died on October 1264. Della Torre, however, never get Raimondo formal appointment, and after Martino's death, the once loyal Pallavicino family switched side to Visconti, scheming the assassination of Paganino della Torre, podestà of Vercelli, on January 1266. In response, the new lord of Milan Napoleone della Torre executed 53 nobles, suspected of conjuring. This vicious act undermined Della Torre's grab on Milan, aggravated by Pope Gregory X, a Visconti of Piacenza, who in 1273 confirmed Ottone Visconti as legal Archbishop of Milan. Napoleone della Torre reacted exiling all noble families who don't supported him, causing the formation of an émigré coalition in Novara and Pavia. Using their financial and military support, Ottone's nephew Teobaldo Visconti led an army in Vercelli, occupying Castelseprio. Defeated by Torriani's forces, Teobaldo fled to Lurate, near Como, but after a battle in Gallarate, his last forces were defeated and he was beheaded by Napoleone della Torre in 1276. Ottone, returned in Lombardy in the same year, recruited his supporters near Desio, where he was canon, and after a bloody battle on January 1277, Visconti emerged victorius. Napoleone della Torre was imprisoned and tortured to death in Castel Baradello, while his brother Francesco was executed after the battle. Ottone entered in Milan on 22 January 1277, becoming the first Visconti de facto ruler of the city.
