The siege of Mantua ended on 2 February 1797 when Austrian field marshal Dagobert Sigmund von Wurmser surrendered the fortress city to French forces under Napoleon Bonaparte. The capitulation concluded a blockade begun in June 1796, and, combined with losses from four failed relief attempts, helped push Austria toward peace negotiations in 1797.

Background and detail

Background. After defeating Feldzeugmeister Johann Beaulieu's Austrian army at the Battle of Borghetto, the French under General of Division Bonaparte forced the Austrians to abandon the Mincio River line, leave a strong garrison in Mantua, and retreat north to Trento. The French then invested the fortress in early June 1796, beginning a blockade that would dominate the Italian Campaign of 1796–1797.

The Fortress. In 1796 Mantua was nearly surrounded by water and linked by causeways to the fortified suburbs of Cittadella to the north and San Giorgio to the east. Its position made it a formidable obstacle, and the siege became the hinge point determining which side would control Northern Italy.

Relief Attempts. Wurmser led attempts to relieve the garrison of Joseph Canto d'Irles. The first, launched at the end of July 1796, was a three-pronged attack by 49,000 men; further reliefs are documented in the Castiglione, Bassano, Arcola, and Rivoli campaign orders of battle. The eventual surrender, together with the heavy losses incurred during four unsuccessful relief attempts, contributed to Austria's decision to seek peace in 1797.

Surrender and Consequences. With no hope of further help, Wurmser surrendered Mantua in early February 1797, ending a siege that had run from 4 June 1796 to 2 February 1797. The surrender, together with losses from the failed reliefs, enabled Napoleon to invade Austria and convince the Austrians to sue for peace in 1797.
