The battle of the 16th November was thus far favourable to the French, that they had driven back the Austrians, and made many prisoners in the commencement of the day; but they had also lost many men; and Napoleon, if he had gained ground in the day, was fain to return to his position at night, lest Davidowich, by the defeat of Vaubois, might either relieve Mantua, or move on Verona. The 17th was to be a day more decisive. [Sidenote: SECOND BATTLE OF ARCOLA.] [Sidenote: Nov. 17.] The field of battle, and the preliminary manœuvres, were much the same as on the preceding day; but those of the French were nearly disconcerted by the sinking of one of the boats which constituted their bridge over the Adige. The Austrians instantly advanced on the demi-brigade which had been stationed on the left bank to defend the bridge. But the French having repaired the damage, advanced in their turn, and compelled the Austrians to retreat upon the marsh. Massena directed his attack on Porcil--General Robert pressed forward on Arcola. But it was at the point where he wished to cross the Alpon that Buonaparte chiefly desired to attain a decided superiority; and in order to win it, he added stratagem to audacity. Observing one of his columns repulsed, and retreating along the causeway, he placed the 32d regiment in ambuscade in a thicket of willows which bordered the rivulet, and saluting the pursuing enemy with a close, heavy, and unexpected fire, instantly rushed to close with the bayonet, and attacking the flank of a column of nearly three thousand Croats, forced them into the marsh, where most of them perished. It was now that, after a calculation of the losses sustained by the enemy, Napoleon conceived their numerical superiority so far diminished, and their spirit so much broken, that he need no longer confine his operations to the dikes, but meet his enemy on the firm plain which extended beyond the Alpon. He passed the brook by means of a temporary bridge which had been prepared during night, and the battle raged as fiercely on the dry level, as it had done on the dikes and amongst the marshes. The Austrians fought with resolution, the rather that their left, though stationed on dry ground, was secured by a marsh which Buonaparte had no means of turning. But though this was the case, Napoleon contrived to gain his point by impressing on the enemy an idea that he had actually accomplished that which he had no means of doing. This he effected by sending a daring officer, with about thirty of the guides, (his own body-guards they may be called,) with four trumpets; and directing these determined cavaliers to charge, and the trumpets to sound, as if a large body of horse had crossed the marsh. Augereau attacked the Austrian left at the same moment; and a fresh body of troops advancing from Legnago, compelled them to retreat, but not to fly.
