The Siege of Mantua came to an end on February 2, 1797, when AustrianField MarshalDagobert Sigismund von Würmser capitulated to the army of GeneralNapoleon Bonaparte. Only 16,000 members of the garrison were capable of marching out as prisoners of war. Leaving General Jean-Mathieu-Philibert Sérurier to oversee the surrender, Bonaparte invaded Romagna, which formed part of the Papal States. The Papal army was led by Austrian Field Marshall-Lieutenant Michelangelo Alessandro Colli-Marchi, a veteran of the Seven Years' War. Colli had served in the army of the Kingdom of Sardinia-Piedmont from 1793 to 1796 and had faced Bonaparte before in the disastrous Montenotte Campaign. He was an intelligent and capable officer, but sometimes had to be carried on a stretcher due to old wounds. The French Revolutionary Army was highly skilled, and fresh off recent successes in Italy. The Papal army, on the other hand, consisted of several “permanent regiments” and organized town or regionally trained militia battalions or cavalry squadrons called out in times of need. This was typical of many minor Italian state armies of this period including the Sardinian-Piedmontese army defeated by Bonaparte in 1796. The Papal army included several fortress garrison battalions, tasked with defending the state fortresses dotting the seacoast, ports and major towns.
Battle
On February 3, Victor sighted Colli's troops on the Senio at Castel Bolognese near Faenza. The Papal artillery began firing upon the advancing French forces, inflicting casualties. The French army then launched an assault over the Senio, dispersing the Papal infantry and cavalry and capturing 14 artillery guns. The French army made short work of their adversaries- for a loss of 100 casualties, Victor's soldiers inflicted 800 casualties on the Papal troops. In addition, the French captured 1,200 men, 14 artillery pieces, eight caissons, and eight colors. Victor's corps included a grenadier reserve commanded by General Jean Lannes.
Aftermath
The port of Ancona surrendered to Victor on 9 February with its Papal garrison of 1,200 men and 120 artillery guns. There were no French casualties. By the Treaty of Tolentino on 19 February, Pope Pius VI was forced to deliver works of art, treasures, territory, and 30 million francs to France.
