Marcognet led his division at the Battle of the Mincio River on 8 February 1814. The Franco-Italian army advanced and blundered into Count Heinrich von Bellegarde's Austrian army, resulting in a confused meeting engagement. Eugène and Grenier advanced across the Mincio River on the right and center, pushing back the Austrians in front of them. The divisions of Rouyer and Quesnel led the attack with cavalry on both flanks, supported by Marcognet and Teodoro Lechi's Italian Guard. Meanwhile, Jean-Antoine Verdier's troops were barely holding out against greatly superior Austrian forces on the left flank. As Eugène directed Rouyer and Quesnel to the left to help Verdier, he brought Marcognet into the first line. In the end, the French advance was halted by a mass of Austrians and both sides pulled back. The French suffered 3,000 killed and wounded plus 500 captured, while inflicting losses of 2,800 killed and wounded and 1,200 captured on the Austrians.
