Napoleon, who had left Milan and taken up a strong position at Stradella, was in a state of the utmost anxiety, fearing that Melas was about to escape the net. The 10th and 11th of June passed without any definite information of the Austrian movements. On the 12th of June his impatience became so great that he abandoned his position at Stradella and advanced to the heights of Tortona. On the next day he passed the Scrivia and entered the plain of Marengo, and drove a small Austrian force from the village. Napoleon was convinced that Melas had escaped, and it is queer commentary upon the kind of scouting done at the time that the whereabouts of the Austrian army was totally unknown to the French, although the two were but a few miles apart. Leaving Victor in possession of the village of Marengo, and placing Lannes on the plain, Napoleon started back to headquarters at Voghera. By a lucky chance the Scrivia had overflowed its banks, and he could not cross. Thus he remained near enough to Marengo to repair his terrible mistake in concluding that Melas meant to shut himself up in Genoa. Desaix, just returned from Egypt, reached headquarters June 11, and was at once put in command of the Boudet division. On June 13 Desaix was ordered to march upon Novi, by which route Melas would have to pass to Genoa. Thus on the eve of one of the most famous battles in history, the soldier who won it was completely at fault as to the position and the purpose of his foe. His own army was widely scattered, and it was only by accident that he was within reach of the point where the blow fell. The staff-officer whom he had sent to reconnoitre, had reported that the Austrians were not in possession of the bridges over the Bormida. In fact they were in possession of these bridges, and at daybreak, June 14, they began to pour across them with the intention of crushing the weak French forces at Marengo and of breaking through Napoleon’s net. About thirty-six thousand Austrians fell upon the sixteen thousand French. Victor was driven out of the village, and by ten o’clock in the morning his troops were in disorderly retreat. The superb courage of Lannes stayed the rout. With the utmost firmness he held his troops in hand, falling back slowly and fighting desperately as he retired. At full speed Napoleon came upon the field, bringing the consular guard and Monnier’s division. Couriers had already been sent to bring Desaix back to the main army; but before these messengers reached him, he had heard the cannonade, guessed that Melas had struck the French at Marengo, and at once set his columns in motion toward the field of battle.
