Seeing a mass of French troops approaching, the Austrians abandoned Veronetta and fell back to San Michele. The French mauled Rosenberg's division and forced Johann Maria Philipp Frimont out of San Michele after street fighting. By the end of the day, Masséna's troops closed up to the main defense line of Archduke Charles. The French counted losses of 527 killed and wounded, plus 157 captured. Again, Austrian casualties were heavier, numbering 1,926 killed and wounded, with 1,114 prisoners. Archduke Charles of Austria-Teschen, himself acutely aware of the dire consequences of the fall of Ulm, was planning to move towards Vienna, in order to reinforce the remains of the Austrian army and link up with the Russians. However, in order to avoid having Masséna's men on his heels, he decided to suddenly turn and face the French, hoping that by defeating them he would ensure the success of his march towards inner Austria. Archduke Charles had already made preparations for a French attack, occupying the strategic village of Caldiero, through which passed the main Lombardian road ('the Verona road') and deploying no less than 58 cannons and 24 mortars. The Austrian forces were divided into three main groups: to the right, Joseph Anton von Simbschen occupied the heights of Colognola and the ravine of San Zeno, where his cavalry was massed; in the centre, General Count Heinrich von Bellegarde covered the Verona road, holding the entrenchments north of the road as well as Monte Rocca and Ponterotta, to the south of the road; the left was formed by Prince Heinrich XV of Reuss-Plauen's forces, which extended the Austrian line to Chiavighette and had the detached division of General Joseph Armand von Nordmann cover the Adige in front of Chiavica del Christo. Upon reconnoitering the Austrian position, Masséna drew up his plan. General Gardanne was to form the apex of the army, deploying his forces on both sides of the Verona road, supported by Partouneaux's reserve, Jean Louis Brigitte Espagne's cavalry and a part of Julien Augustin Joseph Mermet's dragoons. To the left Molitor's division would deploy close to Ca dell'Ara and would set out to take the heights of Colognola. To the right, Duhesme would march on Gombione in order to fall upon Caldiero, but he was ordered to make his move towards midday.
