Buonaparte penetrated the design of the veteran general, and suffered him without disturbance to march towards Bassano upon the Brenta, in order to occupy the line of operations on which he intended to manœuvre, with the secret intention that he would himself assume the offensive, and overwhelm Davidowich as soon as the distance betwixt them precluded a communication betwixt that general and Wurmser. He left General Kilmaine, an officer of Irish extraction[183] in whom he reposed confidence, with about three thousand men, to cover the siege of Mantua, by posting himself under the walls of Verona, while, concentrating a strong body of forces, Napoleon marched upon the town of Roveredo, situated in the valley of the Adige, and having in its rear the strong position of Calliano. The town is situated on the high road to Trent, and Davidowich lay there with twenty-five thousand Austrians, intended to protect the Tyrol, while Wurmser moved down the Brenta, which runs in the same direction with the Adige, but at about thirty miles' distance, so that no communication for mutual support could take place betwixt Wurmser and his lieutenant-general. It was upon Davidowich that Buonaparte first meant to pour his thunder. [Sidenote: Sept. 4.] The battle of Roveredo, fought upon the 4th of September, was one of that great general's splendid days. Before he could approach the town, one of his divisions had to force the strongly intrenched camp of Mori, where the enemy made a desperate defence. Another attacked the Austrians on the opposite bank of the Adige, (for the action took place on both sides of the river,) until the enemy at length retreated, still fighting desperately. Napoleon sent his orders to General Dubois, to charge with the first regiment of hussars:--he did so, and broke the enemy, but fell mortally wounded with three balls. "I die," he said, "for the Republic--bring me but tidings that the victory is certain."[184]
