With this view, ere Buonaparte broke up from Ivrea, Lannes, who had commanded his vanguard with so much gallantry, victorious at Romano, seemed about to improve his advantage. He had marched on Chiavaso, and seizing on a number of boats and small vessels, appeared desirous to construct a bridge over the Po at that place. This attracted the attention of Melas. It might be equally a preliminary to an attack on Turin, or a movement towards Genoa. But as the Austrian general was at the same time alarmed by the descent of General Thurreau's division from Mont Cenis, and their capture of Susa and La Brunette, Turin seemed ascertained to be the object of the French; and Melas acted on this idea. He sent a strong force to oppose the establishment of the bridge, and while his attention was thus occupied, Buonaparte was left to take the road to Milan unmolested. Vercelli was occupied by the cavalry under Murat, and the Sesia was crossed without obstacle. The Ticino, a broad and rapid river, offered more serious opposition; but the French found four or five small boats, in which they pushed across an advanced party under General Gerard. The Austrians, who opposed the passage, were in a great measure cavalry, who could not act on account of the woody and impracticable character of the bank of the river. The passage was accomplished; and, upon the 2d of June, Buonaparte entered Milan,[553] where he was received with acclamations by a numerous class of citizens, who looked for the re-establishment of the Cisalpine Republic. The Austrians were totally unprepared for this movement. Pavia fell into the hands of the French; Lodi and Cremona were occupied, and Pizzighitone was invested.[554]
Meanwhile, Buonaparte, fixing his residence in the ducal palace of Milan, employed himself in receiving the deputations of various public bodies, and in re-organizing the Cisalpine government, while he waited impatiently to be joined by Moncey and his division, from Mont Saint Gothard. They arrived at length, but marching more slowly than accorded with the fiery promptitude of the first consul, who was impatient to relieve the blockade of Genoa, which place he concluded still held out. He now issued a proclamation to his troops, in which he described, as the result of the efforts he expected from them, "Cloudless glory and solid peace."[555] On the 9th of June his armies were again in motion.
SITUATION OF MELAS.
Melas, an excellent officer, had at the same time some of the slowness imputed to his countrymen, or of the irresolution incident to the advanced age of eighty years,—for so old was the opponent of Buonaparte, then in the very prime of human life,—or, as others suspect, it may have been orders from Vienna which detained the Austrian general so long at Turin, where he lay in a great measure inactive. It is true, that on receiving notice of Buonaparte's march on Milan, he instantly despatched orders to General Ott, as we have already stated, to raise the siege of Genoa, and join him with all possible speed; but it seemed, that in the meantime, he might have disquieted Buonaparte's lines of communication, by acting upon the river Dorea, attacking Ivrea, in which the French had left much baggage and artillery, and relieving the fort of Bard. Accordingly, he made an attempt of this kind, by detaching 6000 men to Chiavaso, who were successful in delivering some Austrian prisoners at that place; but Ivrea proved strong enough to resist them, and the French retaining possession of that place, the Austrians could not occupy the valley of the Dorea, or relieve the besieged fortress of Bard.[556]
The situation of Melas now became critical. His communications with the left, or north bank of the Po, were entirely cut off, and by a line stretching from Fort Bard to Placentia, the French occupied the best and fairest share of the north of Italy, while he found himself confined to Piedmont. The Austrian army, besides, was divided into two parts,—one under Ott, which was still near Genoa, that had so lately surrendered to them,—one with Melas himself, which was at Turin. Neither were agreeably situated. That of Genoa was observed on its right by Suchet, whose army, reinforced with the garrison which, retaining their arms, evacuated that city under Massena, might soon be expected to renew the offensive. There was, therefore, the greatest risk, that Buonaparte, pushing a strong force across the Po, might attack and destroy either the division of Ott, or that of Melas himself, before they were able to form a junction. To prevent such a catastrophe, Ott received orders to march forward on the Ticino, while Melas, moving towards Alexandria, prepared to resume his communications with his lieutenant-general.
Buonaparte, on his part, was anxious to relieve Genoa; news of the fall of which had not reached him. With this view he resolved to force his passage over the Po, and move against the Austrians, who were found to occupy in strength the villages of Casteggio and Montebello. These troops proved to be the greater part of the very army which he expected to find before Genoa, and which was commanded by Ott, but which had moved westward, in conformity to the orders of Melas.
9th June.
General Lannes, who led the vanguard of the French, as usual, was attacked early in the morning, by a superior force, which he had much difficulty in resisting. The nature of the ground gave advantage to the Austrian cavalry, and the French were barely able to support their charges. At length the division of Victor came up to support Lannes, and the victory became no longer doubtful, though the Austrians fought most obstinately. The fields being covered with tall crops of grain, and especially of rye, the different bodies were frequently hid until they found themselves at the bayonet's point, without having had any previous opportunity to estimate each other's force; a circumstance which led to much close fighting, and necessarily to much slaughter. At length the Austrians retreated, leaving the field of battle covered with their dead, and above 5000 prisoners in the hands of their enemies.[557]
General Ott rallied the remains of his army under the walls of Tortona. From the prisoners taken at the battle of Montebello, as this action was called, Buonaparte learned, for the first time, the surrender of Genoa, which apprised him that he was too late for the enterprise which he had meditated. He therefore halted his army for three days in the position of Stradella, unwilling to advance into the open plain of Marengo, and trusting that Melas would find himself compelled to give him battle in the position which he had chosen, as most unfavourable for the Austrian cavalry. He despatched messengers to Suchet, commanding him to cross the mountains by the Col di Cadibona, and march on the river Scrivia, which would place him in the rear of the Austrians.
