Davidovich placed Colonel Karl Weidenfeld and the "Preiss" Infantry Regiment 24 in a formidable position in the Adige gorge to cover the retreat of his forces. However, the regiment's morale was poor after suffering casualties and being hustled out of several defensive lines. Aided by artillery fire directed by General of Brigade Elzéar Auguste Cousin de Dommartin, Masséna's troops attacked in heavy columns and broke through. Believing themselves well-covered by Weidenfeld's force, Vukassovich and Spork allowed their troops to cook dinner when they arrived in Calliano. Without warning, the French interrupted the proceedings by storming into the camp in the late afternoon. The result was a rout of the surviving Austrians.
