Antoine-Guillaume Rampon joined the French army as a private soldier and rose in rank to become a general officer during the French Revolutionary Wars. He fought in many battles under Napoleon Bonaparte in Italy and Egypt. In one celebrated battle, he rallied his troops to defend the key Monte Negino redoubt against the Austrians. He saw limited service during the Napoleonic Wars. His surname can be found among the names inscribed under the Arc de Triomphe.

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.
