Battle of Fombio

The Battle of Fombio was fought between the French Army of Italy led by Napoleon Bonaparte and the Austrian army under Feldzeugmeister Johann Peter Beaulieu between 7 and 9 May 1796. It was the decisive strategic point of the campaign, as Bonaparte crossed the Po River at Piacenza in Beaulieu's rear, threatening both Milan and the Austrian line of communications. This threat forced the Austrian army to withdraw to the east.

After forcing the Kingdom of Sardinia-Piedmont to sue for peace at the end of the Montenotte Campaign, Bonaparte turned on the Austrians, who retreated to the north bank of the Po. The French army commander ordered General of Division Jean-Mathieu-Philibert Sérurier to launch a pinning attack on Beaulieu's positions near Valenza. Forming an advance guard of 3,500 grenadiers and 1,500 cavalry, Bonaparte placed it under General of Brigade Claude Dallemagne. Then he sent Dallemagne on a rapid march to the east along the south bank of the Po. The advance guard was followed by General of Division Amédée Emmanuel François Laharpe's division. Bonaparte intended to turn the Austrian left flank by crossing the Po near Piacenza.
