Eugène had an army of 41,000, but detached 7,000 troops to guard his southern flank on the Po River, leaving 34,000 for the upcoming battle. His army consisted of the Italian Royal Guards, a cavalry division, and two pseudo-corps (not at full strength) under generals Paul Grenier and Jean-Antoine Verdier. The former's troops were positioned around Mantua while those of the latter defended the fortress of Peschiera at the northern edge of the battlefield. Eugène's plan called for a double envelopment that would eventually unite Grenier's and Verdier's forces and allow them to drive the Austrians from the field. It was a good plan on paper, but double envelopment, especially on this scale, usually works with heavy numerical superiority or tactical mobility, neither of which the French had.
