The 'Battle of Casalecchio' took place on
June 26,
1402 near the town of
Casalecchio di Reno, near
Bologna. At this battle, a Bolognese army under
Giovanni I Bentivoglio opposed
Gian Galeazzo Visconti, Duke of
Milan, and his allies, the
Malatesta of
Rimini and the
Gonzaga of
Mantua.
Bologna was aided by
Florence in these cities' struggle to halt the expansion of Visconti's power.
Visconti was aided by many Italian lords and
condottieri. The commander in chief was the famous leader
Alberico da Barbiano. Chiavello Chiavelli, lord of
Fabriano, was present at the battle. With Facino Cane, the
condottiere Ludovico Gabriotto Cantelli (Ludovico da Parma) commanded the Milanese vanguard of 2,000
cavalry. Cantelli fought Bernardo della Serra and captured Rigo Galletto, Pietro da Carrara, and Brunoro Della Scala, who were taken to
Parma.
The Bolognese-Florentine army was under
Muzio Attendolo.
The Bolognese were routed and their leader Giovanni I Bentivoglio was killed. Gian Galeazzo Visconti took Bologna and planned to assault Florence next. However, he fell ill on
August 10,
1402 and died on
September 3.
