War of the First Coalition: Napoleon Bonaparte wins his first victory as an army commander at the Battle of Montenotte, splitting the Austrian and Piedmontese armies away from each other, and marking the beginning of the Piedmontese surrender in the war.

The War of the First Coalition was a set of wars that several European powers fought between 1792 and 1797, against France. They were only loosely allied and fought without much apparent coordination or agreement; each power had its eye on a different part of France it wanted to appropriate after a French defeat, which never occurred.

Napoleon Bonaparte, later known by his regnal name Napoleon I, was a French general and statesman who rose to prominence during the French Revolution and led a series of military campaigns across Europe during the French Revolutionary and Napoleonic Wars from 1796 to 1815. He led the French Republic as First Consul from 1799 to 1804, then ruled the French Empire as Emperor of the French from 1804 to 1814, and briefly again in 1815. He was King of Italy from 1805 to 1814 and Protector of the Confederation of the Rhine from 1806 to 1813.

The Battle of Montenotte was fought on 12 April 1796, during the French Revolutionary Wars, between the French army under General Napoleon Bonaparte and an Austrian corps under Count Eugène-Guillaume Argenteau. The French won the battle, which was fought near the village of Cairo Montenotte in the Kingdom of Piedmont-Sardinia. The modern town is located in the northwestern part of Italy. On 11 April, Argenteau led 3,700 men in several assaults against a French mountaintop redoubt but failed to take it. By the morning of the 12th, Bonaparte concentrated large forces against Argenteau's now-outnumbered troops. The strongest French push came from the direction of the mountaintop redoubt, but a second force fell on the weak Austrian right flank and overwhelmed it. In its hasty retreat from the field, Argenteau's force lost heavily and was badly disorganized. This attack against the boundary between the Austrian and Sardinian armies threatened to sever the link between the two allies. This action was part of the Montenotte Campaign.
