The first phase of the campaign satisfactorily settled, Napoleon was free to turn his attention to the "arch-enemy" to whom he was now considerably superior in numbers (35,000 to 25,000). The day after the signature of the armistice of Cherasco he began preparing for a new advance and also for the role of arbiter of the destinies of Italy. Many whispers there were, even in his own army, as to the dangers of passing on without "revolutionizing" aristocratic Genoa and monarchical Piedmont, and of bringing Venice, the pope and the Italian princes into the field against the French. But Bonaparte, flushed with victory, and better informed than the malcontents of the real condition of Italy, never hesitated. His first object was to drive out Beaulieu, his second to push through Tirol, and his only serious restriction the chance that the armistice with Piedmont would not result in a definitive treaty. Beaulieu had fallen back into Lombardy, and now bordered the Po right and left of Valenza. To achieve further progress, Napoleon had first to cross that river, and the point and method of crossing was the immediate problem, a problem the more difficult as Napoleon had no bridge train and could only make use of such existing bridges as he could seize intact.[10] If he crossed above Valenza, he would be confronted by one river-line after another, on one of which at least Beaulieu would probably stand to fight. But quite apart from the immediate problem, Napoleon's intention was less to beat the Austrians than to dislodge them. He needed a foothold in Lombardy which would make him independent of, and even a menace to, Piedmont. If this were assured, he could for a few weeks entirely ignore his communications with France and strike out against Beaulieu, dethrone the king of Sardinia, or revolutionize Parma, Modena and the papal states according to circumstances. Piacenza. Milan, therefore, was his objective, and Tortona-Piacenza his route thither. To give himself every chance, he had stipulated with the Piedmontese authorities for the right of passing at Valenza, and he had the satisfaction of seeing Beaulieu fall into the trap and concentrate opposite that part of the river. The French meantime had moved to the region Alessandria-Tortona. Thence on the 6th of May Bonaparte, with a picked body of troops, set out for a forced march on Piacenza, and that night the advanced guard was 30 m. on the way, at Castel San Giovanni, and Laharpe's and the cavalry divisions at Stradella, 10 m. behind them. Augereau was at Broni, Massena at Sale and Serurier near Valenza, the whole forming a rapidly extending fan, 50 m. from point to point. If the Piacenza detachment succeeded in crossing, the army was to follow rapidly in its track. If, on the other hand, Beaulieu fell back to oppose the advanced guard, the Valenza divisions would take advantage of his absence to cross there. In either case, be it observed, the Austrians were to be _evaded_, not brought to action.
