At first the Imperialists gained important successes; for though the French held their own on the Brenta, yet their forces in the Tyrol were driven down the valley of the Adige with losses so considerable that Bonaparte was constrained to order a general retreat on Verona. He discerned that from this central position he could hold in check Alvintzy's troops marching westwards from Vicenza and prevent their junction with the Imperialists under Davidovich, who were striving to thrust Vaubois' division from the plateau of Rivoli.
But before offering battle to Alvintzy outside Verona, Bonaparte paid a flying visit to his men posted on that plateau in order to rebuke the wavering and animate the whole body with his own dauntless spirit. Forming the troops around him, he addressed two regiments in tones of grief and anger. He reproached them for abandoning strong positions in a panic, and ordered his chief staff officer to inscribe on their colours the ominous words: "They are no longer of the Army of Italy."[66] Stung by this reproach, the men begged with sobs that the general would test their valour before disgracing them for ever. The young commander, who must have counted on such a result to his words, when uttered to French soldiers, thereupon promised to listen to their appeals; and their bravery in the ensuing fights wiped every stain of disgrace from their colours. By such acts as these did he nerve his men against superior numbers and adverse fortune.
Their fortitude was to be severely tried at all points. Alvintzy occupied a strong position on a line of hills at Caldiero, a few miles to the east of Verona. His right wing was protected by the spurs of the Tyrolese Alps, while his left was flanked by the marshes which stretch between the rivers Alpon and Adige; and he protected his front by cannon skilfully ranged along the hills. All the bravery of Masséna's troops failed to dislodge the right wing of the Imperialists. The French centre was torn by the Austrian cannon and musketry. A pitiless storm of rain and sleet hindered the advance of the French guns and unsteadied the aim of the gunners; and finally they withdrew into Verona, leaving behind 2,000 killed and wounded, and 750 prisoners (November 12th). This defeat at Caldiero—for it is idle to speak of it merely as a check—opened up a gloomy vista of disasters for the French; and Bonaparte, though he disguised his fears before his staff and the soldiery, forthwith wrote to the Directors that the army felt itself abandoned at the further end of Italy, and that this fair conquest seemed about to be lost. With his usual device of under-rating his own forces and exaggerating those of his foes, he stated that the French both at Verona and Rivoli were only 18,000, while the grand total of the Imperialists was upwards of 50,000. But he must have known that for the present he had to deal with rather less than half that number. The greater part of the Tyrolese force had not as yet descended the Adige below Roveredo; and allowing for detachments and losses, Alvintzy's array at Caldiero barely exceeded 20,000 effectives.
Bonaparte now determined to hazard one of the most daring turning movements which history records. It was necessary at all costs to drive Alvintzy from the heights of Caldiero before the Tyrolese columns should overpower Vaubois' detachment at Rivoli and debouch in the plains west of Verona. But, as Caldiero could not be taken by a front attack, it must be turned by a flanking movement. To any other general than Bonaparte this would have appeared hopeless; but where others saw nothing but difficulties, his eye discerned a means of safety. South and south-east of those hills lies a vast depression swamped by the flood waters of the Alpon and the Adige. Morasses stretch for some miles west of the village of Arcola, through which runs a road up the eastern bank of the Alpon, crossing that stream at the aforenamed village and leading to the banks of the Adige opposite the village of Ronco; another causeway, diverging from the former a little to the north of Ronco, leads in a north-westerly direction towards Porcil. By advancing from Ronco along these causeways, and by seizing Arcola, Bonaparte designed to outflank the Austrians and tempt them into an arena where the personal prowess of the French veterans would have ample scope, and where numbers would be of secondary importance. Only heads of columns could come into direct contact; and the formidable Austrian cavalry could not display its usual prowess. On these facts Bonaparte counted as a set-off to his slight inferiority in numbers.
In the dead of night the divisions of Augereau and Masséna retired through Verona. Officers and soldiers were alike deeply discouraged by this movement, which seemed to presage a retreat towards the Mincio and the abandonment of Lombardy. To their surprise, when outside the gate they received the order to turn to the left down the western bank of the Adige. At Ronco the mystery was solved. A bridge of boats had there been thrown across the Adige; and, crossing this without opposition, Augereau's troops rapidly advanced along the causeway leading to Arcola and menaced the Austrian rear, while Masséna's column denied north-west, so as directly to threaten his flank at Caldiero. The surprise, however, was by no means complete; for Alvintzy himself purposed to cross the Adige at Zevio, so as to make a dash on Mantua, and in order to protect his flank he had sent a detachment of Croats to hold Arcola. These now stoutly disputed Augereau's progress, pouring in from the loopholed cottages volleys which tore away the front of every column of attack. In vain did Augereau, seizing the colours, lead his foremost regiment to the bridge of Arcola. Riddled by the musketry, his men fell back in disorder. In vain did Bonaparte himself, dismounting from his charger, seize a flag, rally these veterans and lead them towards the bridge. The Croats, constantly reinforced, poured in so deadly a fire as to check the advance: Muiron, Marmont, and a handful of gallant men still pressed on, thereby screening the body of their chief; but Muiron fell dead, and another officer, seizing Bonaparte, sought to drag him back from certain death. The column wavered under the bullets, fell back to the further side of the causeway, and in the confusion the commander fell into the deep dyke at the side. Agonized at the sight, the French rallied, while Marmont and Louis Bonaparte rescued their beloved chief from capture or from a miry death, and he retired to Ronco, soon followed by the wearied troops.[67]
[Illustration: PLAN TO ILLUSTRATE THE VICTORY OF ARCOLA.]
This memorable first day of fighting at Arcola (November 15th) closed on the strange scene of two armies encamped on dykes, exhausted by an almost amphibious conflict, like that waged by the Dutch "Beggars" in their war of liberation against Spain. Though at Arcola the republicans had been severely checked, yet further west Masséna had held his own; and the French movement as a whole had compelled Alvintzy to suspend any advance on Verona or on Mantua, to come down from the heights of Caldiero, and to fight on ground where his superior numbers were of little avail. This was seen on the second day of fighting on the dykes opposite Arcola, which was, on the whole, favourable to the smaller veteran force. On the third day Bonaparte employed a skilful ruse to add to the discouragement of his foes. He posted a small body of horsemen behind a spinney near the Austrian flank, with orders to sound their trumpets as if for a great cavalry charge. Alarmed by the noise and by the appearance of French troops from the side of Legnago and behind Arcola, the demoralized white-coats suddenly gave way and retreated for Vicenza.
Victory again declared for the troops who could dare the longest, and whose general was never at a loss in face of any definite danger. Both armies suffered severely in these desperate conflicts;[68] but, while the Austrians felt that the cup of victory had been snatched from their very lips, the French soldiery were dazzled by this transcendent exploit of their chief. They extolled his bravery, which almost vied with the fabulous achievement of Horatius Cocles, and adored the genius which saw safety and victory for his discouraged army amidst swamps and dykes. Bonaparte himself, with that strange mingling of the practical and the superstitious which forms the charm of his character, ever afterwards dated the dawn of his fortune in its full splendour from those hours of supreme crisis among the morasses of Arcola. But we may doubt whether this posing as the favourite of fortune was not the result of his profound knowledge of the credulity of the vulgar herd, which admires genius and worships bravery, but grovels before persistent good luck.
Though it is difficult to exaggerate the skill and bravery of the French leader and his troops, the failure of his opponents is inexplicable but for the fact that most of their troops were unable to manoeuvre steadily in the open, that Alvintzy was inexperienced as a commander-in-chief, and was hampered throughout by a bad plan of campaign. Meanwhile the other Austrian army, led by Davidovich, had driven Vaubois from his position at Rivoli; and had the Imperialist generals kept one another informed of their moves, or had Alvintzy, disregarding a blare of trumpets and a demonstration on his flank and rear, clung to Arcola for two days longer—the French would have been nipped between superior forces. But, as it was, the lack of accord in the Austrian movements nearly ruined the Tyrolese wing, which pushed on triumphantly towards Verona, while Alvintzy was retreating eastwards. Warned just in time, Davidovich hastily retreated to Roveredo, leaving a whole battalion in the hands of the French. To crown this chapter of blunders, Würmser, whose sortie after Caldiero might have been most effective, tardily essayed to break through the blockaders, when both his colleagues were in retreat. How different were these ill-assorted moves from those of Bonaparte. His maxims throughout this campaign, and his whole military career, were: (1) divide for foraging, concentrate for fighting; (2) unity of command is essential for success; (3) time is everything. This firm grasp of the essentials of modern warfare insured his triumph over enemies who trusted to obsolete methods for the defence of antiquated polities.[69]
The battle of Arcola had an important influence on the fate of Italy and Europe. In the peninsula all the elements hostile to the republicans were preparing for an explosion in their rear which should reaffirm the old saying that Italy was the tomb of the French. Naples had signed terms of peace with them, it is true; but the natural animosity of the Vatican against its despoilers could easily have leagued the south of Italy with the other States that were working secretly for their expulsion. While the Austrians were victoriously advancing, these aims were almost openly avowed, and at the close of the year 1796 Bonaparte moved south to Bologna in order to guide the Italian patriots in their deliberations and menace the Pope with an invasion of the Roman States. From this the Pontiff was for the present saved by new efforts on the part of Austria. But before describing the final attempt of the Hapsburgs to wrest Italy from their able adversary, it will be well to notice his growing ascendancy in diplomatic affairs.
