The Battle of Bicocca or La Bicocca was fought on 27 April 1522, during the Italian War of 1521–26. A combined French and Venetian force under Odet of Foix, Viscount of Lautrec, was decisively defeated by an Imperial–Spanish and Papal army under the overall command of Prospero Colonna. Lautrec then withdrew from Lombardy, leaving the Duchy of Milan in Imperial hands.
