 They defeated the imperial garrison under the imperial "podestà" Enrico Testa near Borghetto di Taro and occupied the city with no resistance, since the garrison of Enzio of Sardinia, Frederick's son, was besieging Quinzano.Frederick immediately diverted his troops to Emilia, and at the same time he called for reinforcements from friendly lords and communes.The imperial army was also joined by Enzio, who raised the siege of Quinzano, and by a Cremonese contingent led by Ezzelino III da Romano, as well as by soldiers from Padua, Verona, and Vicenza.
