In the fourth relief of Mantua, the new army commander József Alvinczi assigned Reuss to command the largest column in his army, nearly 7,900 soldiers. Reuss followed the west bank of the Adige, while Vukassovich's column marched on the east bank, and the rest of the army followed roads and trails farther west near Monte Baldo. During the Battle of Rivoli, the troops under Reuss bravely fought their way out of the river bottom to the plateau against tenacious resistance. At this moment, a desperate French counterattack panicked some Austrians from the other columns and drove them to seek refuge in the river valley. Disordered by fleeing troops and attacked from two sides by the French, Reuss' column retreated to the bottom of the gorge where their commander managed to rally them. With Reuss checked, Bonaparte defeated the remaining Austrians on the plateau and won the battle.
