CHAPTER VIII
Neutrality of Venice—The Archduke Charles—Battle of Tagliamento—Retreat of the Archduke—Treaty of Leoben—War with Venice—Venice conquered.
Napoleon was now master of all northern Italy, with the exception of the territories of Venice, which antique government, though no longer qualified to keep equal rank with the first princes of Europe, was still proud and haughty, and not likely to omit any favourable opportunity of aiding Austria in the great and common object of ridding Italy of the French. Buonaparte heard without surprise that the Doge had been raising new levies, and that the senate could command an army of 50,000, composed chiefly of fierce and semi-barbarous Sclavonian mercenaries. He demanded what these demonstrations meant, and was answered that Venice had no desire but to maintain a perfect neutrality. Meantime there was not wanting a strong party, throughout the Venetian territories of the mainland, who were anxious to emulate the revolutionary movements of the great cities of Lombardy, and to emancipate themselves from the yoke of the Venetian oligarchy, as their neighbours had done by that of the Austrian crown. Insurrections occurred at Bergamo, Brescia, and elsewhere; and Buonaparte, though little disposed to give the inhabitants of these places the boon they were in quest of, saw and profited by the opportunity of dividing, by their means, the resources, and shaking the confidence, of the senate. After some negotiation, he told the Venetian envoy that he granted the prayer of his masters. "Be neuter," said he, "but see that your neutrality be indeed sincere and perfect. If any insurrection occur in my rear, to cut off my communications in the event of my marching on Germany—if any movement whatever betray the disposition of your senate to aid the enemies of France, be sure that vengeance will follow—from that hour the independence of Venice has ceased to be."
More than a month had now elapsed since Alvinzi's defeat at Rivoli; in nine days the war with the Pope had reached its close; and, having left some garrisons in the towns on the Adige, to watch the neutrality of Venice, Napoleon hastened to carry the war into the hereditary dominions of the Emperor. Twenty thousand fresh troops had recently joined his victorious standard from France; and, at the head of perhaps a larger force than he had ever before mustered, he proceeded to the frontier of the Frioul, where, according to his information, the main army of Austria, recruited once more to its original strength, was preparing to open a sixth campaign—under the orders, not of Alvinzi, but of a general young like himself, and hitherto eminently successful—the same who had already by his combinations baffled two such masters in the art of war as Jourdan and Moreau—the Archduke Charles; a prince on whose high talents the last hopes of the empire seemed to repose.
To give the details of the sixth campaign, which now commenced, would be to repeat the story which has been already five times told. The Archduke, fettered by the Aulic Council of Vienna, saw himself compelled to execute a plan which he had discrimination enough to condemn. The Austrian army once more commenced operations on a double basis—one great division on the Tyrolese frontier, and a greater under the Archduke himself on the Friulese; and Napoleon—who had, even when acting on the defensive, been able, by the vivacity of his movements, to assume the superiority on whatever point he chose to select—was not likely to strike his blows with less skill and vigour, now that his numbers, and the acquiescence of Italy behind him, permitted him to assume the offensive.
Buonaparte found the Archduke posted behind the river Tagliamento, in front of the rugged Carinthian mountains, which guard the passage in that quarter from Italy to Germany. Detaching Massena to the Piave, where the Austrian division of Lusignan were in observation, he himself determined to charge the Archduke in front. Massena was successful in driving Lusignan before him as far as Belluno, (where a rear guard of 500 surrendered,) and thus turned the Austrian flank. Buonaparte then attempted and effected the passage of the Tagliamento. After a great and formal display of his forces, which was met by similar demonstrations on the Austrian side of the river, he suddenly broke up his line and retreated. The Archduke, knowing that the French had been marching all the night before, concluded that the general wished to defer the battle till another day; and in like manner withdrew to his camp. About two hours after Napoleon rushed with his whole army, who had merely lain down in ranks, upon the margin of the Tagliamento, no longer adequately guarded—and had forded the stream ere the Austrian line of battle could be formed. In the action which followed (March 12) the troops of the Archduke displayed much gallantry, but every effort to dislodge Napoleon failed; at length retreat was judged necessary. The French followed hard behind. They stormed Gradisca, where they made 5000 prisoners; and—the Archduke pursuing his retreat—occupied in the course of a few days Trieste, Fiume, and every stronghold in Carinthia. In the course of a campaign of twenty days, the Austrians fought Buonaparte ten times, but the overthrow on the Tagliamento was never recovered; and the Archduke, after defending Styria inch by inch as he had Carinthia, at length adopted the resolution of reaching Vienna by forced marches, there to gather round him whatever force the loyalty of his nation could muster, and make a last stand beneath the walls of the capital.
This plan, at first sight the mere dictate of despair, was in truth that of a wise and prudent general. The Archduke had received intelligence from two quarters of events highly unfavourable to the French. General Laudon, the Austrian commander on the Tyrol frontier, had descended thence with forces sufficient to overwhelm Buonaparte's lieutenants on the upper Adige, and was already in possession of the whole Tyrol, and of several of the Lombard towns. Meanwhile the Venetian Senate, on hearing of these Austrian successes, had plucked up courage to throw aside their flimsy neutrality, and not only declared war against France, but encouraged their partizans in Verona to open the contest with an inhuman massacre of the French wounded in the hospitals of that city. The vindictive Italians, wherever the French party was inferior in numbers, resorted to similar atrocities. The few troops left in Lombardy by Napoleon were obliged to shut themselves up in garrisons, which the insurgent inhabitants of the neighbouring districts invested. The Venetian army passed the frontier; and, in effect, Buonaparte's means of deriving supplies of any kind from his rear were for the time wholly cut off. It was not wonderful that the Archduke should, under such circumstances, anticipate great advantage from enticing the French army into the heart of Austria; where, divided by many wide provinces and mighty mountains and rivers from France, and with Italy once more in arms behind them, they should have to abide the encounter of an imperial army, animated by all the best motives that can lend vigour to the arm of man; fighting for their own hearths under the eyes of their own sovereign; seconded everywhere by the loyalty of the peasants; and well convinced that, if they could compel their enemy to a retreat, his total ruin must be the consequence.
The terror of the Aulic Council stepped in to prevent the Archduke from reaping either the credit or the disgrace of this movement. Vienna was panic-struck on hearing that Buonaparte had stormed the passes of the Julian Alps; the imperial family sent their treasure into Hungary; the middle ranks, whose interest is always peace, became clamorous for some termination to a war, which during six years had been so unfortunate; and the Archduke was ordered to avail himself of the first pretence which circumstances might afford for the opening of a negotiation.
