Buonaparte remained but five days in Milan; the citadel of that place still held out against him; but he left a detachment to blockade it, and proceeded himself in pursuit of Beaulieu. The Austrian had now planted the remains of his army behind the Mincio, having his left on the great and strong city of Mantua, which has been termed "the citadel of Italy," and his right at Peschiera a Venetian fortress, of which he took possession in spite of the remonstrances of the Doge. Peschiera stands where the Mincio flows out of "its parent lake," the Lago di Guarda. That great body of waters, stretching many miles backwards towards the Tyrolese Alps, at once extended the line of defence, and kept the communication open with Vienna. The Austrian veteran occupied one of the strongest positions that it is possible to imagine. The invader hastened once more to dislodge him.
The French Directory, meanwhile, had begun to entertain certain not unnatural suspicions as to the ultimate designs of their young general, whose success and fame had already reached so astonishing a height. They determined to check, if they could, the career of an ambition which they apprehended might outgrow their control. Buonaparte was ordered to take half his army, and lead it against the Pope and the King of Naples, and leave the other half to terminate the contest with Beaulieu, under the orders of Kellerman. But he acted on this occasion with the decision which these Directors in vain desired to emulate. He answered by resigning his command. "One half of the army of Italy," said he, "cannot suffice to finish the matter with the Austrian. It is only by keeping my force entire that I have been able to gain so many battles and to be now in Milan. You had better have one bad general than two good ones." The Directory durst not persist in displacing the chief whose name was considered as the pledge of victory. Napoleon resumed the undivided command, to which now, for the last time, his right had been questioned.
Another unlooked-for occurrence delayed, for a few days longer, the march upon Mantua. The heavy exactions of the French, and even more perhaps the wanton contempt with which they treated the churches and the clergy, had produced or fostered the indignation of a large part of the population throughout Lombardy. Reports of new Austrian levies being poured down the passes of the Tyrol were spread and believed. Popular insurrections against the conqueror took place in various districts: at least 30,000 were in arms. At Pavia the insurgents were entirely triumphant; they had seized the town, and compelled the French garrison to surrender.
This flame, had it been suffered to spread, threatened immeasurable evil to the French cause. Lannes instantly marched to Benasco, stormed the place, plundered and burnt it, and put the inhabitants to the sword without mercy. The general in person appeared before Pavia; blew the gates open; easily scattered the townspeople; and caused the leaders to be executed, as if they had committed a crime in endeavouring to rescue their country from the arm of a foreign invader. Everywhere the same ferocious system was acted on. The insurgent commanders were tried by courts-martial, and shot without ceremony. At Lugo, where a French squadron of horse had been gallantly and disastrously defeated, the whole of the male inhabitants were massacred. These bloody examples quelled the insurrections; but they fixed the first dark and indelible stain on the name of Napoleon Buonaparte.
The spirit of the Austrian and Catholic parties in Lombardy thus crushed, the French advanced on the Mincio. The general made such disposition of his troops, that Beaulieu doubted not he meant to pass that river, if he could, at Peschiera. Meantime he had been preparing to repeat the scene of Placenza;—and actually, on the 30th of May, forced the passage of the Mincio, not at Peschiera, but further down at Borghetto. The Austrian garrison at Borghetto in vain destroyed one arch of the bridge. Buonaparte supplied the breach with planks; and his men, flushed with so many victories, charged with a fury not to be resisted. Beaulieu was obliged to abandon the Mincio, as he had before the Adda and the Po, and to take up the new line of the Adige.
Meanwhile an occurrence, which may be called accidental, had nearly done more than repay the Austrians for all their reverses. The left of their line, stationed still further down the Mincio,—at Puzzuolo, no sooner learned from the cannonade that the French were at Borghetto, than they hastened to ascend the stream, with the view of assisting the defence of their friends. They came too late for this; the commander at Borghetto had retreated before they arrived. They, however, came unexpectedly; and, such was the chance, reached Valleggio after the French army had pursued the Austrians through it and onwards—and, at the moment when Buonaparte and a few friends, considering the work of the day to be over, and this village as altogether in the rear of both armies, were about to sit down to dinner in security. Sebetendorff, who commanded the Puzzuolo division, came rapidly, little guessing what a prize was near him, into the village. The French general's attendants had barely time to shut the gates of the inn, and alarm their chief by the cry "To arms." Buonaparte threw himself on horseback, and galloping out by a back passage, effected the narrowest of escapes from the most urgent of dangers. Sebetendorff was soon assaulted by a French column, and retreated, after Beaulieu's example, on the line of the Adige. Buonaparte, profiting by the perilous adventure of Valleggio, instituted a small corps of picked men, called Guides, to watch continually over his personal safety. Such was the germ from which sprung the famous Imperial Guard of Napoleon.
The Austrian had, in effect, abandoned for the time the open country of Italy. He now lay on the frontier, between the vast tract of rich provinces which Napoleon had conquered, and the Tyrol. The citadel of Milan, indeed, still held out; but the force there was not great, and, cooped up on every side, could not be expected to resist much longer. Mantua, which possessed prodigious natural advantages, and into which the retreating general had flung a garrison of full 15,000 men, was, in truth, the last and only Italian possession of the imperial crown, which, as it seemed, there might still be a possibility of saving. Beaulieu anxiously waited the approach of new troops from Germany, to attempt the relief of this great city; and his antagonist, eager to anticipate the efforts of the imperial government, sat down immediately before it.
Mantua lies on an island, being cut off on all sides from the main land by the branches of the Mincio, and approachable only by five narrow causeways, of which three were defended by strong and regular fortresses or entrenched camps, the other two by gates, drawbridges, and batteries. Situated amidst stagnant waters and morasses, its air is pestilential, especially to strangers. The garrison were prepared to maintain the position with their usual bravery; and it remained to be seen whether the French general possessed any new system of attack, capable of abridging the usual operations of the siege, as effectually as he had already done by those of the march and the battle. His commencement was alarming: of the five causeways, by sudden and overwhelming assaults, he obtained four; and the garrison were cut off from the main land, except only at the fifth causeway, the strongest of them all, named, from a palace near it, La Favorita. It seemed necessary, however, in order that this blockade might be complete, that the Venetian territory, lying immediately beyond Mantua, should be occupied by the French. The power of this ancient government was no longer such as to inspire much respect, and Buonaparte resolved that the claim of neutrality should form no obstacle to his measures. The French Directory had already most ungenerously trampled on the dignity of Venice, by demanding that she should no longer afford a retreat to the illustrious exile, the Count of Provence, eldest surviving brother of Louis XVI.[9] That unfortunate prince had, accordingly, though most reluctantly, been desired to quit the Venetian states, and had already passed to the Rhine, where his gallant cousin, the Prince of Condé, had long been at the head of a small and devoted army composed of the expatriated gentry of France. Buonaparte, however, chose to treat the reluctance with which Venice had been driven to this violation of her hospitality, as a new injury to his government: he argued that a power who had harboured in friendship, and unwillingly expelled, the Pretender to the French monarchy, had lost all title to forbearance on the part of the Revolutionary forces. This was a gross and ungenerous insult, and it was a gratuitous one; for he had a far better argument behind. The imperial general had, as we have seen, neglected the reclamations of the Doge, when it suited his purpose to occupy Peschiera. "You are too weak," said Buonaparte, when the Venetian envoy reached his headquarters, "to enforce neutrality on hostile nations such as France and Austria. Beaulieu did not respect your territory when his interest bade him violate it; nor shall I hesitate to occupy whatever falls within the line of the Adige." In effect, garrisons were placed forthwith in Verona, and all the strong places of that domain. The tricolor flag now waved at the mouth of the Tyrolese passes; and Napoleon, leaving Serrurier to blockade Mantua, returned to Milan, where he had important business to arrange.
The King of Naples, utterly confounded by the successes of the French, was now anxious to procure peace, almost on whatever terms, with the apparently irresistible Republic. Nor did it, for the moment, suit Buonaparte's views to contemn his advances. A peace with this prince would withdraw some valuable divisions from the army of Beaulieu; and the distance of the Neapolitan territory was such, that the French had no means of carrying the war thither with advantage, so long as Austria retained the power of sending new forces into Italy by the way of the Tyrol. He concluded an armistice accordingly, which was soon followed by a formal peace, with the King of the Two Sicilies; and the Neapolitan troops, who had recently behaved with eminent gallantry, abandoning the Austrian general, began their march to the south of Italy.
This transaction placed another of Napoleon's destined victims entirely within his grasp. With no friend behind him, the Pope saw himself at the mercy of the invader; and in terror prepared to submit. Buonaparte occupied immediately his legations of Bologna and Ferrara, making prisoners in the latter of these towns four hundred of the papal troops, and a cardinal, under whose orders they were. The churchman militant was dismissed on parole; but, being recalled to headquarters, answered that his master, the Pope, had given him a dispensation to break his promise. This exercise of the old dispensing power excited the merriment of the conquerors. The Vatican, meanwhile, perceived that no time was to be lost. The Spanish resident at the Roman court was despatched to Milan; and the terms on which the holy father was to obtain a brief respite were at length arranged. Buonaparte demanded and obtained a million sterling, a hundred of the finest pictures and statues in the papal gallery, a large supply of military stores, and the cession of Ancona, Ferrara, and Bologna, with their respective domains.
