Beaulieu now withdrew into the Tyrol. Sardinia made peace, and terms were offered by the pope and by Naples. Leghorn was garrisoned with French troops; all the English goods lying in this harbor, to the value of twelve million pounds, were confiscated. The strongly fortified city of Mantua, defended by the Austrians under their gallant leader, Canto d'Irles, was besieged by Bonaparte. A fresh body of Austrian troops under Wurmser crossed the mountains to their relief; but Wurmser, instead of advancing with his whole force, incautiously pressed forward with thirty-two thousand men through the valley of the Adige, while Quosdanowich led eighteen thousand along the western shore of the Lake of Garda. Bonaparte instantly perceived his advantage, and, attacking the latter, defeated him on the 3d of August, at Lonato. Wurmser had entered Mantua unopposed on the 1st, but, setting out in search of the enemy, was unexpectedly attacked, on the 5th of August, by the whole of Bonaparte's forces at Castiglione, and compelled, like Quosdanowich, to seek shelter in the Tyrol. This senseless mode of attack had been planned by Weirotter, a colonel belonging to the general staff. Wurmser now received reinforcements, and Laner, the general of the engineers, was intrusted with the projection of a better plan. He again weakened the army by dividing his forces. In the beginning of September, Davidowich penetrated with twenty thousand men through the valley of the Adige and was defeated at Roveredo, and Wurmser, who had, meanwhile, advanced with an army of twenty-six thousand men through the valley of the Brenta, met with a similar fate at Bassano. He, nevertheless, escaped the pursuit of the victorious French by making a circuit, and threw himself by a forced march into Mantua, where he was, however, unable to make a lengthy resistance, the city being over-populated and provisions scarce. A fresh army of twenty-eight thousand men, under Alvinzi, sent to his relief[1] through the valley of the Brenta, was attacked in a strong position at Arcole, on the river Alpon. Two dams protected the bank and a narrow bridge, which was, on the 15th of November, vainly stormed by the French, although General Augereau and Bonaparte, with the colors in his hand, led the attack. On the following day, Alvinzi foolishly crossed the bridge and took up an exposed position, in which he was beaten, and, on the third day, he retreated. Davidowich, meanwhile, again advanced from the Tyrol and gained an advantage at Rivoli, but was also forced to retreat before Bonaparte. Wurmser, when too late, made a sally, which was, consequently, useless. The campaign was, nevertheless, for the fifth time, renewed. Alvinzi collected reinforcements and again pushed forward into the valley of the Adige, but speedily lost courage and suffered a fearful defeat, in which twenty thousand of his men were taken prisoners, on the 14th and 15th of January, A.D. 1797, at Rivoli. Provera, on whom he had relied for assistance from Padua, was cut off and taken prisoner with his entire corps. Wurmser capitulated at Mantua with twenty-one thousand men.
