In the meanwhile, Provera communicated with the garrison of Mantua across the lake, and concerted the measures for its relief with Wurmser. On the 16th of January, being the morning after the battle of Rivoli, and the unsuccessful attempt to surprise the suburb of Saint George, the garrison of Mantua sallied from the place in strength, and took post at the causeway of La Favorita, being the only one which is defended by an enclosed citadel or independent fortress. Napoleon, returning at the head of his victorious forces, surrounded and attacked with fury the troops of Provera, while the blockading army compelled the garrison, at the bayonet's point, to re-enter the besieged city of Mantua. Provera, who had in vain, though with much decision and gallantry, attempted the relief of Mantua, which his Imperial master had so much at heart, was compelled to lay down his arms with a division of about five thousand men, whom he had still united under his person. The detached corps which he had left to protect his bridge, and other passes in his rear, sustained a similar fate. Thus one division of the army, which had commenced the campaign of January only on the 7th of that month, were the prisoners of the destined conqueror before ten days had elapsed. The larger army, commanded by Alvinzi, had no better fortune. They were closely pursued from the bloody field of Rivoli, and never were permitted to draw breath or to recover their disorder. Large bodies were intercepted and compelled to surrender, a practice now so frequent among the Austrian troops, that it ceased to be shameful.[224]
