What happened June 1800 AD

After spending several days looking for each other, the two armies collided at the Battle of Marengo on 14 June. General Melas had a numerical advantage, fielding about 30,000 Austrian soldiers while Napoleon commanded 24,000 French troops. The Battle of Marengo was fought on 14 June 1800 between French forces under the First Consul Napoleon Bonaparte and Austrian forces near the city of Alessandria, in Piedmont, Italy. Late in the afternoon, a full division under Louis Desaix arrived on the field and reversed the tide of the battle. A series of artillery barrages and cavalry charges decimated the Austrian army, which fled over the Bormida River back to Alessandria, leaving behind 14,000 casualties.

The Austrian army agreed to abandon Northern Italy once more with the Convention of Alessandria, which granted them safe passage to friendly soil in exchange for their fortresses throughout the region.
