Bernabò Visconti
In 1354 he entered the service of cardinal Gil de Albornoz at Milan, to fight against the Ghibelline leader Bernabò Visconti. In November of the following year he became Captain General of the Papal Army, receiving half the fief of Onano in the Marche. In 1359, always for Albornoz, he directed the military operations against Forlì and Forlimpopoli, which were stormed in July. The following year Giovanni Visconti da Oleggio, lord of Bologna, declared war on Bernabò Visconti, but was forced to ask (in exchange for the lordship over his city) the help of Albornoz, who sent Pietro Farnese to take possession of it.
