Part 33

On the 29th Quasdanovich attacked Sauret at Salo, drove him towards Desenzano, and pushed on to Gavardo and thence into Brescia. Wurmser expelled Massena's advanced guard from La Corona, and captured in succession the Monte Baldo and Rivoli posts. The Brenta column approached Verona with little or no fighting. News of this column led Napoleon early in the day to close up Despinoy, Massena and Kilmaine at Castelnuovo, and to order Augereau from Legnago to advance on Montebello (19 m. east of Verona) against Davidovich's left rear. But after these orders had been despatched came the news of Sauret's defeat, and this moment was one of the most anxious in Napoleon's career. He could not make up his mind to give up the siege of Mantua, but he hurried Augereau back to the Mincio, and sent order after order to the officers on the lines of communication to send all convoys by the Cremona instead of by the Brescia road. More, he had the baggage, the treasure and the sick set in motion at once for Marcaria, and wrote to Serurier a despatch which included the words "perhaps we shall recover ourselves ... but I must take serious measures for a retreat." On the 30th he wrote: "The enemy have broken through our line in three places ... Sauret has evacuated Salo ... and the enemy has captured Brescia. You see that our communications with Milan and Verona are cut." The reports that came to him during the morning of the 30th enabled him to place the main body of the enemy opposite Massena, and this, without in the least alleviating the gravity of the situation, helped to make his course less doubtful. Augereau was ordered to hold the line of the Molinella, in case Davidovich's attack, the least-known factor, should after all prove to be serious; Massena to reconnoitre a road from Peschiera through Castiglione towards Orzinovi, and to stand fast at Castelnuovo opposite Wurmser as long as he could. Sauret and Despinoy were concentrated at Desenzano with orders on the 31st to clear the main line of retreat and to recapture Brescia. The Austrian movements were merely the continuation of those of the 29th. Quasdanovich wheeled inwards, his right finally resting on Montechiaro and his left on Salo. Wurmser drove back Massena to the west side of the Mincio. Davidovich made a slight advance.

Relief of Mantua.

In the late evening Bonaparte held a council of war at Roverbella. The proceedings of this council are unknown, but it at any rate enabled Napoleon to see clearly and to act. Hitherto he had been covering the siege of Mantua with various detachments, the defeat of any one of which might be fatal to the enterprise. Thus, when he had lost his main line of retreat, he could assemble no more than 8000 men at Desenzano to win it back. Now, however, he made up his mind that the siege could not be continued, and bitter as the decision must have been, it gave him freedom. At this moment of crisis the instincts of the great captain came into play, and showed the way to a victory that would more than counterbalance the now inevitable failure. Serurier was ordered to spike the 140 siege guns that had been so welcome a few days before, and, after sending part of his force to Augereau, to establish himself with the rest at Marcaria on the Cremona road. The field forces were to be used on interior lines. On the 31st Sauret, Despinoy, Augereau and Kilmaine advanced westward against Quasdanovich. The first two found the Austrians at Salo and Lonato and drove them back, while with Augereau and the cavalry Bonaparte himself made a forced march on Brescia, never halting night or day till he reached the town and recovered his depots. Meantime Serurier had retired (night of July 31), Massena had gradually drawn in towards Lonato, and Wurmser's advanced guard triumphantly entered the fortress (August 1).

Lonato and Castiglione.

The Austrian general now formed the plan of crushing Bonaparte between Quasdanovich and his own main body. But meantime Quasdanovich had evacuated Brescia under the threat of Bonaparte's advance and was now fighting a long irregular action with Despinoy and Sauret about Gavardo and Salo, and Bonaparte, having missed his expected target, had brought Augereau by another severe march back to Montechiaro on the Chiese. Massena was now assembled between Lonato and Ponte San Marco, and Serurier was retiring quietly on Marcaria. Wurmser's main body, weakened by the detachment sent to Mantua, crossed the Mincio about Valeggio and Goito on the 2nd, and penetrated as far as Castiglione, whence Massena's rearguard was expelled. But a renewed advance of Quasdanovich, ordered by Wurmser, which drove Sauret and Despinoy back on Brescia and Lonato, in the end only placed a strong detachment of the Austrians within striking distance of Massena, who on the 3rd attacked it, front to front, and by sheer fighting destroyed it, while at the same time Augereau recaptured Castiglione from Wurmser. On the 4th Sauret and Despinoy pressed back Quasdanovich beyond Salo and Gavardo. One of the Austrian columns, finding itself isolated and unable to retreat with the others, turned back to break its way through to Wurmser, and was annihilated by Massena in the neighbourhood of Lonato. On this day Augereau fought his way towards Solferino, and Wurmser, thinking rightly or wrongly that he could not now retire to the Mincio without a battle, drew up his whole force, close on 30,000 men, in the plain between Solferino and Medole. The finale may be described in very few words. Bonaparte, convinced that no more was to be feared from Quasdanovich, and seeing that Wurmser meant to fight, called in Despinoy's division to the main body and sent orders to Serurier, then far distant on the Cremona road, to march against the left flank of the Austrians. On the 5th the battle of Castiglione was fought. Closely contested in the first hours of the frontal attack till Serurier's arrival decided the day, it ended in the retreat of the Austrians over the Mincio and into Tirol whence they had come.

Thus the new way had failed to keep back Wurmser, and the old had failed to crush Napoleon. Each was the result of its own conditions. In former wars a commander threatened as Napoleon was, would have fallen back at once to the Adda, abandoning the siege in such good time that he would have been able to bring off his siege artillery. Instead of this Bonaparte hesitated long enough to lose it, which, according to accepted canons was a waste, and held his ground, which was, by the same rules, sheer madness. But Revolutionary discipline was not firm enough to stand a retreat. Once it turned back, the army would have streamed away to Milan and perhaps to the Alps (cf. 1799), and the only alternative to complete dissolution therefore was fighting.

As to the manner of this fighting, even the principle of "relative superiority" failed him so long as he was endeavouring to cover the siege and again when his chief care was to protect his new line of retreat and to clear his old. In this period, viz. up to his return from Brescia on the 2nd of August, the only "mass" he collected delivered a blow in the air, while the covering detachments had to fight hard for bare existence. Once released from its trammels, the Napoleonic principle had fair play. He stood between Wurmser and Quasdanovich, ready to fight either or both. The latter was crushed, thanks to local superiority and the resolute leading of Massena, but at Castiglione Wurmser actually outnumbered his opponent till the last of Napoleon's precautionary dispositions had been given up, and Serurier brought back from the "alternative line of retreat" to the battlefield. The moral is, again, that it was not the mere fact of being on interior lines that gave Napoleon the victory, but his "tact," his fine appreciation of the chances in his favour, measured in terms of time, space, attacking force and containing power. All these factors were greatly influenced by the ground, which favoured the swarms and columns of the French and deprived the brilliant Austrian cavalry of its power to act. But of far greater importance was the mobility that Napoleon's personal force imparted to the French. Napoleon himself rode five horses to death in three days, and Augereau's division marched from Roverbella to Brescia and back to Montechiaro, a total distance of nearly 50 m., in about thirty-six hours. This indeed was the foundation of his "relative superiority," for every hour saved in the time of marching meant more freedom to destroy one corps before the rest could overwhelm the covering detachments and come to its assistance.

Wurmser's plan for the relief of Mantua, suited to its purpose, succeeded. But when he made his objective the French field army, he had to take his own army as he found it, disposed for an altogether different purpose. A properly, combined attack of convergent columns framed _ab initio_ by a good staff officer, such as Mack, might indeed have given good results. But the success of such a plan depends principally on the assailant's original possession of the initiative, and not on the chances of his being able to win it over to his own side when operations, as here, are already in progress. When the time came to improvise such a plan, the initiative had passed over to Napoleon, and the plan was foredoomed.

By the end of the second week in August the blockade of Mantua had been resumed, without siege guns. But still under the impression of a great victory gained, Bonaparte was planning a long forward stride. He thought that by advancing past Mantua directly on Trieste and thence onwards to the Semmering he could impose a peace on the emperor. The Directory, however, which had by now focussed its attention on the German campaign, ordered him to pass through Tirol and to co-operate with Moreau, and this plan, Bonaparte, though protesting against an Alpine venture being made so late in the year, prepared to execute, drawing in reinforcements and collecting great quantities of supplies in boats on the Adige and Lake Garda. Wurmser was thought to have posted his main body near Trent, and to have detached one division to Bassano "to cover Trieste." The French advanced northward on the 2nd, in three disconnected columns (precisely as Wurmser had done in the reverse direction at the end of July)--Massena (13,000) from Rivoli to Ala, Augereau (9000) from Verona by hill roads, keeping on his right rear, Vaubois (11,000) round the Lake of Garda by Riva and Torbole. Sahuguet's division (8000) remained before Mantua. The French divisions successfully combined and drove the enemy before them to Trent.

There, however, they missed their target. Wurmser had already drawn over the bulk of his army (22,000) into the Val Sugana, whence, with the Bassano division as his advanced guard, he intended once more to relieve Mantua, while Davidovich with 13,000 (excluding detachments) was to hold Tirol against any attempt of Bonaparte to join forces with Moreau.

Thus Austria was preparing to hazard a second (as in the event she hazarded a third and a fourth) highly trained and expensive professional army in the struggle for the preservation of a fortress, and we must conclude that there were weighty reasons which actuated so notoriously cautious a body as the Council of War in making this unconditional venture. While Mantua stood, Napoleon, for all his energy and sanguineness, could not press forward into Friuli and Carniola, and immunity from a Republican visitation was above all else important for the Vienna statesmen, governing as they did more or less discontented and heterogeneous populations that had not felt the pressure of war for a century and more. The Austrians, so far as is known, desired no more than to hold their own. They no longer possessed the superiority of _moral_ that guarantees victory to one side when both are materially equal. There was therefore nothing to be gained, commensurate with the risk involved, by fighting a battle in the open field. _In Italien siegt nicht die Kavallerie_ was an old saying in the Austrian army, and therefore the Austrians could not hope to win a victory of the first magnitude. The only practicable alternative was to strengthen Mantua as opportunities offered themselves, and to prolong the passive resistance as much as possible. Napoleon's own practice in providing for secondary theatres of war was to economize forces and to delay a decision, and the fault of the Austrians, viewed from a purely military standpoint, was that they squandered, instead of economizing, their forces to gain time. If we neglect pure theory, and regard strategy as the handmaiden of statesmanship--which fundamentally it is--we cannot condemn the Vienna authorities unless it be first proved that they grossly exaggerated the possible results of Bonaparte's threatened irruption. And if their capacity for judging the political situation be admitted, it naturally follows that their object was to preserve Mantua _at all costs_--which object Wurmser, though invariably defeated in action, did in fact accomplish.

Bassano.

When Massena entered Trent on the morning of the 5th of September, Napoleon became aware that the force in his front was a mere detachment, and news soon came in that Wurmser was in the Val Sugana about Primolano and at Bassano. This move he supposed to be intended to cover Trieste, being influenced by his own hopes of advancing in that direction, and underestimating the importance, to the Austrians, of preserving Mantua. He therefore informed the Directory that he could not proceed with the Tirol scheme, and spent one more day in driving Davidovich well away from Trent. Then, leaving Vaubois to watch him, Napoleon marched Augereau and Massena, with a rapidity he scarcely ever surpassed, into the Val Sugana. Wurmser's rearguard was attacked and defeated again and again, and Wurmser himself felt compelled to stand and fight, in the hope of checking the pursuit before going forward into the plains. Half his army had already reached Montebello on the Verona road, and with the rear half he posted himself at Bassano, where on the 8th he was attacked and defeated with heavy losses. Then began a strategic pursuit or general chase, and in this the mobility of the French should have finished the work so well begun by their tactics.

But Napoleon directed the pursuers so as to cut off Wurmser from Trieste, not from Mantua. Massena followed up the Austrians to Vicenza, while Augereau hurried towards Padua, and it was not until late on the 9th that Bonaparte realized that his opponent was heading for Mantua via Legnago. On the 10th Massena crossed the Adige at Ronco, while Augereau from Padua reached Montagnara. Sahuguet from Mantua and Kilmaine from Verona joined forces at Castellaro on the 11th, with orders to interpose between Wurmser and the fortress. Wurmser meantime had halted for a day at Legnago, to restore order, and had then resumed his march. It was almost too late, for in the evening, after having to push aside the head of Massena's column at Cerea, he had only reached Nogara, some miles short of Castellaro, and close upon his rear was Augereau, who reached Legnago that night. On the 12th, eluding Sahuguet by a detour to the southward, he reached Mantua, with all the columns of the French, weary as most of them were, in hot pursuit. After an attempt to keep the open field, defeated in a general action on the 15th, the relieving force was merged in the garrison, now some 28,000 in all. So ended the episode of Bassano, the most brilliant feature of which as usual was the marching power of the French infantry. This time it sufficed to redeem even strategical misconceptions and misdirections. Between the 5th and the 11th, besides fighting three actions, Massena had marched 100 m. and Augereau 114.

Feldzeugmeister Alvintzi was now appointed to command a new army of relief. This time the mere distribution of the troops imposed a concentric advance of separate columns, for practically the whole of the fresh forces available were in Carniola, the Military Frontier, &c., while Davidovich was still in Tirol. Alvintzi's intention was to assemble his new army (29,000) in Friuli, and to move on Bassano, which was to be occupied on the 4th of November. Meantime Davidovich (18,000) was to capture Trent, and the two columns were to connect by the Val Sugana. All being well, Alvintzi and Davidovich, still separate, were then to converge on the Adige between Verona and Legnago. Wurmser was to co-operate by vigorous sorties. At this time Napoleon's protective system was as follows: Kilmaine (9000) investing Mantua, Vaubois (10,000) at Trent, and Massena (9000) at Bassano and Treviso, Augereau (9000) and Macquard (3000) at Verona and Villafranca constituting, for the first time in these operations, important mobile reserves. Hearing of Alvintzi's approach in good time, he meant first to drive back Davidovich, then with Augereau, Massena, Macquard and 3000 of Vaubois's force to fall upon Alvintzi, who, he calculated, would at this stage have reached Bassano, and finally to send back a large force through the Val Sugana to attack Davidovich. This plan practically failed.

Caldiero.

Instead of advancing, Vaubois was driven steadily backward. By the 6th, Davidovich had fought his way almost to Roveredo, and Alvintzi had reached Bassano and was there successfully repelling the attacks of Massena and Augereau. That night Napoleon drew back to Vicenza. On the 7th Davidovich drove in Vaubois to Corona and Rivoli, and Alvintzi came within 5 m. of Vicenza. Napoleon watched carefully for an opportunity to strike out, and on the 8th massed his troops closely around the central point of Verona. On the 9th, to give himself air, he ordered Massena to join Vaubois, and to drive back Davidovich at all costs. But before this order was executed, reports came in to the effect that Davidovich had suspended his advance. The 10th and 11th were spent by both sides in relative inaction, the French waiting on events and opportunities, the Austrians resting after their prolonged exertions. Then, on the afternoon of the 11th, being informed that Alvintzi was approaching, Napoleon decided to attack him. On the 12th the advanced guard of Alvintzi's army was furiously assailed in the position of Caldiero. But the troops in rear came up rapidly, and by 4 P.M. the French were defeated all along the line and in retreat on Verona. Napoleon's situation was now indeed precarious. He was on "interior lines," it is true, but he had neither the force nor the space necessary for the delivery of rapid radial blows. Alvintzi was in superior numbers, as the battle of Caldiero had proved, and at any moment Davidovich, who had twice Vaubois's force, might advance to the attack of Rivoli. The reserves had proved insufficient, and Kilmaine had to be called up from Mantua, which was thus for the third time freed from the blockaders. Again the alternatives were retreat, in whatever order was possible to Republican armies, and beating the nearest enemy at any sacrifice. Napoleon chose the latter, though it was not until the evening of the 14th that he actually issued the fateful order.

The Austrians, too, had selected the 15th as the date of their final advance on Verona, Davidovich from the north, Alvintzi via Zevio from the south. But Napoleon was no longer there; leaving Vaubois to hold Davidovich as best he might, and posting only 3000 men in Verona, he had collected the rest of his small army between Albaro and Ronco. His plan seems to have been to cross the Adige well in rear of the Austrians, to march north on to the Verona-Vicenza highway, and there, supplying himself from their convoys, to fight to the last. On the 15th he had written to the Directory, "The weakness and the exhaustion of the army causes me to fear the worst. We are perhaps on the eve of losing Italy." In this extremity of danger the troops passed the Adige in three columns near Ronco and Albaredo, and marched forward along the dikes, with deep marshes and pools on either hand. If Napoleon's intention was to reach the dry open ground of S. Bonifacio in rear of the Austrians, it was not realized, for the Austrian army, instead of being at the gates of Verona, was still between Caldiero and S. Bonifacio, heading, as we know, for Zevio. Thus Alvintzi was able, easily and swiftly, to wheel to the south.

Arcola.

The battle of Arcola almost defies description. The first day passed in a series of resultless encounters between the heads of the columns as they met on the dikes. In the evening Bonaparte withdrew over the Adige, expecting at every moment to be summoned to Vaubois's aid. But Davidovich remained inactive, and on the 16th the French again crossed the river. Massena from Ronco advanced on Porcile, driving the Austrians along the causeway thither, but on the side of Arcola, Alvintzi had deployed a considerable part of his forces on the edge of the marshes, within musket shot of the causeway by which Bonaparte and Augereau had to pass, along the Austrian front, to reach the bridge of Arcola. In these circumstances the second day's battle was more murderous and no more decisive than the first, and again the French retreated to Ronco. But Davidovich again stood still, and with incredible obstinacy Bonaparte ordered a third assault for the 17th, using indeed more tactical expedients than before, but calculating chiefly on the fighting powers of his men and on the exhaustion of the enemy. Massena again advanced on Porcile, Robert's brigade on Arcola, but the rest, under Augereau, were to pass the Alpone near its confluence with the Adige, and joining various small bodies which passed the main stream lower down, to storm forward on dry ground to Arcola. The Austrians, however, themselves advanced from Arcola, overwhelmed Robert's brigade on the causeway and almost reached Ronco. This was perhaps the crisis of the battle, for Augereau's force was now on the other side of the stream, and Massena, with his back to the new danger, was approaching Porcile. But the fire of a deployed regiment stopped the head of the Austrian column; Massena, turning about, cut into its flank on the dike; and Augereau, gathering force, was approaching Arcola from the south. The bridge and the village were evacuated soon afterwards, and Massena and Augereau began to extend in the plain beyond. But the Austrians still sullenly resisted. It was at this moment that Bonaparte secured victory by a mere ruse, but a ruse which would have been unprofitable and ridiculous had it not been based on his fine sense of the moral conditions. Both sides were nearly fought out, and he sent a few trumpeters to the rear of the Austrian army to sound the charge. They did so, and in a few minutes the Austrians were streaming back to S. Bonifacio. This ended the drama of Arcola, which more than any other episode of these wars, perhaps of any wars in modern history, centres on the personality of the hero. It is said that the French fought without spirit on the first day, and yet on the second and third Bonaparte had so thoroughly imbued them with his own will to conquer that in the end they prevailed over an enemy nearly twice their own strength.
