Francesco I Sforza
Although Gianfrancesco I Gonzaga, Marquess of Mantua was nominally commander-in-chief, Colleoni was in fact the real leader of the army. He recaptured many towns and districts for Venice from the Milanese, and when Gonzaga went over to the enemy, Colleoni continued to serve the Venetians under Erasmo of Narni (known as Gattamelata) and Francesco I Sforza, winning battles at Brescia, Verona, and on the Lake of Garda.
