Buonaparte heard in the beginning of October that Alvinzi's columns were in motion: he had placed Vaubois to guard Trent, and Massena at Bassano to check the march of the field-marshal: but neither of these generals was able to hold his ground. The troops of Vaubois were driven from that position of Calliano, the strength of which has been already mentioned, under circumstances which Napoleon considered disgraceful to the character of the French soldiery. Massena avoided battle; but such was the overwhelming superiority of Alvinzi, that he was forced to abandon the position of Bassano. Napoleon himself hurried forward to sustain Massena; and a severe rencontre, in which either side claimed the victory, took place at Vicenza. The French, however, retreated, and Buonaparte fixed his headquarters at Verona. The whole country between the Brenta and the Adige was in the enemy's hands; while the still strong and determined garrison of Mantua in Napoleon's rear, rendering it indispensable for him to divide his forces, made his position eminently critical.

His first care was to visit the discomfited troops of Vaubois. "You have displeased me," said he, "you have suffered yourselves to be driven from positions where a handful of determined men might have bid an army defiance. You are no longer French soldiers! You belong not to the army of Italy." At these words, tears streamed down the rugged cheeks of the grenadiers. "Place us but once more in the van," cried they, "and you shall judge whether we do not belong to the army of Italy." The general dropped his angry tone; and in the rest of the campaign no troops more distinguished themselves than these.

Having thus revived the ardour of his soldiery, Buonaparte concentrated his columns on the right of the Adige, while Alvinzi took up a very strong position on the heights of Caldiero, on the left bank, nearly opposite to Verona. In pursuance of the same system which had already so often proved fatal to his opponents, it was the object of Buonaparte to assault Alvinzi, and scatter his forces, ere they could be joined by Davidowich. He lost no time, therefore, in attacking the heights of Caldiero; but in spite of all that Massena, who headed the charge, could do, the Austrians, strong in numbers and in position, repelled the assailants with great carnage. A terrible tempest prevailed during the action, and Napoleon, in his despatches, endeavoured to shift the blame to the elements.

The country behind Caldiero lying open to Davidowich, it became necessary to resort to other means of assault, or permit the dreaded junction to occur. The genius of Buonaparte suggested to him on this occasion a movement altogether unexpected. During the night, leaving 1,500 men under Kilmaine to guard Verona, he marched for some space rearwards, as if he had meant to retreat on Mantua, which the failure of his recent assault rendered not unlikely. But his columns were ere long wheeled again towards the Adige: and finding a bridge ready prepared, were at once placed on the same side of the river with the enemy,—but in the rear altogether of his position, amidst those wide-spreading morasses which cover the country about Arcola. This daring movement was devised to place Napoleon between Alvinzi and Davidowich; but the unsafe nature of the ground, and the narrowness of the dykes, by which alone he could advance on Arcola, rendered victory difficult, and reverse most hazardous. He divided his men into three columns, and charged at daybreak (Nov. 15) by the three dykes which conduct to Arcola. The Austrian, not suspecting that the main body of the French had evacuated Verona, treated this at first as an affair of light troops; but as day advanced the truth became apparent, and these narrow passages were defended with the most determined gallantry. Augereau headed the first column that reached the bridge of Arcola, and was there, after a desperate effort, driven back with great loss. Buonaparte, perceiving the necessity of carrying the point ere Alvinzi could arrive, now threw himself on the bridge, and seizing a standard, urged his grenadiers once more to the charge.

The fire was tremendous: once more the French gave way. Napoleon himself, lost in the tumult, was borne backwards, forced over the dyke, and had nearly been smothered in the morass, while some of the advancing Austrians were already between him and his baffled column. His imminent danger was observed: the soldiers caught the alarm, and rushing forwards, with the cry, "Save the general," overthrew the Germans with irresistible violence, plucked Napoleon from the bog, and carried the bridge. This was the first battle of Arcola.

This movement revived in the Austrian lines their terror for the name of Buonaparte; and Alvinzi saw that no time was to be lost if he meant to preserve his communication with Davidowich. He abandoned Caldiero, and gaining the open country behind Arcola, robbed his enemy for the moment of the advantage which his skill had gained. Napoleon, perceiving that Arcola was no longer in the rear of his enemy but in his front, and fearful lest Vaubois might be overwhelmed by Davidowich, while Alvinzi remained thus between him and the Brenta, evacuated Arcola, and retreated to Ronco.

Next morning, having ascertained that Davidowich had not been engaged with Vaubois, Napoleon once more advanced upon Arcola. The place was once more defended bravely, and once more it was carried. But this second battle of Arcola proved no more decisive than the first; for Alvinzi still contrived to maintain his main force unbroken in the difficult country behind; and Buonaparte again retreated to Ronco.

The third day was decisive. On this occasion also he carried Arcola; and, by two stratagems, was enabled to make his victory effectual. An ambuscade, planted among some willows, suddenly opened fire on a column of Croats, threw them into confusion, and, rushing from the concealment, crushed them down into the opposite bog, where most of them died. Napoleon was anxious to follow up this success by charging the Austrian main body on the firm ground behind the marshes. But it was no easy matter to reach them there. He had, in various quarters, portable bridges ready for crossing the ditches and canals; but the enemy stood in good order, and three days' hard fighting had nearly exhausted his own men. In one of his conversations at St. Helena, he thus told the sequel. "At Arcola I gained the battle with twenty-five horsemen. I perceived the critical moment of lassitude in either army—when the oldest and bravest would have been glad to be in their tents. All my men had been engaged. Three times I had been obliged to re-establish the battle. There remained to me but some twenty-five Guides. I sent them round on the flank of the enemy with three trumpets, bidding them blow loud and charge furiously. Here is the French cavalry, was the cry; and they took to flight."... The Austrians doubted not that Murat and all the horse had forced a way through the bogs; and at that moment Buonaparte commanding a general assault in front, the confusion became hopeless. Alvinzi retreated finally, though in decent order, upon Montebello.

It was at Arcola that Muiron, who ever since the storming of Little Gibraltar had lived on terms of brotherlike intimacy with Napoleon, seeing a bomb about to explode threw himself between it and his general, and thus saved his life at the cost of his own. Napoleon, to the end of his life, remembered and regretted this heroic friend.

In these three days Buonaparte lost 8000 men: the slaughter among his opponents must have been terrible. Davidowich, in never coming up to join Alvinzi after his success over Vaubois, and Wurmser, in remaining quiet at Mantua, when by advancing with his garrison he might have incommoded the French rear, were guilty of grievous misjudgment or indecision. Once more the rapid combinations of Napoleon had rendered all the efforts of the Austrian cabinet abortive. For two months after the last day of Arcola, he remained the undisturbed master of Lombardy. All that his enemy could show, in set-off for the slaughter and discomfiture of Alvinzi's campaign, was that they retained possession of Bassano and Trent, thus interrupting Buonaparte's access to the Tyrol and Germany. This advantage was not trivial; but it had been dearly bought.
