However, late in the day Moreau committed Paul Grenier's French division to the struggle and the Austrians were driven from the field.

Moreau was supposed to cooperate with Jacques MacDonald's army which was grappling with Alexander Suvorov's Austro-Russians at the Battle of the Trebbia (1799) to the east.

When Moreau moved north, Bellegarde offered battle because his task was to keep the French from joining MacDonald.

Moreau was too late; that day MacDonald's defeated army began to retreat from the Trebbia River.

The French victory was barren because Moreau soon had to withdraw to the mountains to avoid being caught by Suvorov's returning soldiers.
