In 1435 he led a small fleet to Gaeta at the rescue of Francesco Spinola, besieged by Alfonso V of Aragon, and was victorious in the following Battle of Ponza.
Despite his refusal to continue due war, due to the lack of troops to invade the Neapolitan mainland, he received the fief of Serravalle Scrivia and, by the Genoese ally Filippo Maria Visconti, the position of governor of Milan. Later he was ducal commissar in Parma and commander of the Milanese army in the war against Venice. At Casalmaggiore he defeated the Venetian admiral Andrea Quirini (July 1448).

His friends included Enea Silvio Piccolomini, the future pope Pius II.
