Verona, it must be remembered, is on the left bank of the Adige--on the same with the point which was the object of Buonaparte's attack. At nightfall, the whole forces at Verona were under arms; and leaving fifteen hundred men under Kilmaine to defend the place from any assault, with strict orders to secure the gates, and prevent all communication of his nocturnal expedition to the enemy, Buonaparte commenced his march at first to the rear, in the direction of Peschiera; which seemed to imply that his resolution was at length taken to resign the hopes of gaining Mantua, and perhaps to abandon Italy. The silence with which the march was conducted, the absence of all the usual rumours which used in the French army to precede a battle, and the discouraging situation of affairs, appeared to presage the same issue. But after the troops had marched a little way in this direction, the heads of columns were wheeled to the left, out of the line of retreat, and descended the Adige as far as Ronco, which they reached before day. Here a bridge had been prepared, by which they passed over the river, and were placed on the same bank with Arcola, the object of their attack, and lower than the heights of Caldiero. [Sidenote: FIRST BATTLE OF ARCOLA.] [Sidenote: Nov. 15.] There were three causeways by which the marsh of Arcola is traversed--each was occupied by a French column. The central column moved on the causeway which led to the village so named. The dikes and causeways were not defended, but Arcola and its bridge were protected by two battalions of Croats with two pieces of cannon, which were placed in a position to enfilade the causeway. These received the French column with so heavy a fire on its flank, that it fell back in disorder. Augereau rushed forward upon the bridge with his chosen grenadiers; but enveloped as they were in a destructive fire, they were driven back on the main body.
