1796

The French prepared a great advance on three fronts, with Jourdan and Moreau on the Rhine, and Bonaparte in Italy. The three armies were to link up in Tyrol and march on Vienna. Jourdan and Moreau advanced rapidly into Germany, and Moreau had reached Bavaria and the edge of Tyrol by September, but Jourdan was defeated by Archduke Charles at Amberg, and both armies were forced to retreat back across the Rhine.

Napoleon, on the other hand, was completely successful in a daring invasion of Italy. He left Paris on 11 March for Nice to take over the weak and poorly supplied Army of Italy, arriving on 26 March. The army was already being reorganised and supplied when he arrived, and he found that the situation was rapidly improving. He was soon able to carry out the plan for the invasion of Italy that he had been advocating for years, which provided for an advance over the Apennines near Altare to attack the enemy position of Ceva.

The Montenotte Campaign opened after Johann Beaulieu 's Austrian forces attacked the extreme French eastern flank near Genoa on 10 April. Bonaparte countered by attacking and crushing the isolated right wing of the allied armies at the Battle of Montenotte on 12 April. The next day he defeated an Austro-Sardinian force at the Battle of Millesimo. He then won a victory at the Second Battle of Dego, driving the Austrians northeast, away from their Piedmontese allies. Satisfied that the Austrians were temporarily inert, Bonaparte harried Michelangelo Colli 's Piedmontese at Ceva and San Michele Mondovi before whipping them at the Battle of Mondovì. A week later, on 28 April, the Piedmontese signed the Armistice of Cherasco, withdrawing from the hostilities. On 18 May they signed the Treaty of Paris (1796), ceding Savoy and Nice and allowing the French bases to be used against Austria.

After a short pause, Napoleon carried out a brilliant flanking manoeuvre, and crossed the Po at Piacenza, nearly cutting the Austrian line of retreat. The Austrians escaped after the Battle of Fombio, but had their rear-guard mauled at Lodi on 10 May, after which the French took Milan. Bonaparte then advanced eastwards again, drove off the Austrians in the Battle of Borghetto and in June began the Siege of Mantua. Mantua was the strongest Austrian base in Italy. Meanwhile, the Austrians retreated north into the foothills of the Tyrol.

During July and August, Austria sent a fresh army into Italy under Dagobert Wurmser. Wurmser attacked toward Mantua along the east side of Lake Garda, sending Peter Quasdanovich down the west side in an effort to envelop Bonaparte. Bonaparte exploited the Austrian mistake of dividing their forces to defeat them in detail, but in so doing, he abandoned the siege of Mantua, which held out for another six months (Carl von Clausewitz mentioned in On War that the siege might have been able to be kept up if Bonaparte had circumvallated the city). Quasdanovich was overcome at Lonato on 3 August and Wurmser at Castiglione on 5 August. Wurmser retreated to the Tyrol, and Bonaparte resumed the siege.

In September, Bonaparte marched north against Trento in Tyrol, but Wurmser had already marched toward Mantua by the Brenta valley, leaving Paul Davidovich 's force to hold off the French. Bonaparte overran the holding force at the Battle of Rovereto. Then he followed Wurmser down the Brenta valley, to fall upon and defeat the Austrians at the Battle of Bassano on 8 September. Wurmser elected to march for Mantua with a large portion of his surviving troops. The Austrians evaded Bonaparte's attempts to intercept them but were driven into the city after a pitched battle on 15 September. This left nearly 30,000 Austrians trapped in the fortress. This number rapidly diminished due to disease, combat losses, and hunger.

The Austrians sent yet another army under József Alvinczi against Bonaparte in November. Again the Austrians divided their effort, sending Davidovich's corps from the north while Alvinczi's main body attacked from the east. At first they proved victorious over the French at Bassano, Calliano, and Caldiero. But Bonaparte ultimately defeated Alvinczi in the Battle of Arcole southeast of Verona. The French then turned on Davidovich in great strength and chased him into the Tyrol. Wurmser's only sortie was late and ineffectual.

The rebellion in the Vendée was also finally crushed in 1796 by Hoche, but Hoche's attempt to land a large invasion force in Ireland was unsuccessful.
