The retreating enemy were driven through the town of Roveredo, without having it in their power to make a stand. The extreme strength of the position of Calliano seemed to afford them rallying ground. The Adige is there bordered by precipitous mountains, approaching so near its course, as only to leave a pass of forty toises' breadth between the river and the precipice, which opening was defended by a village, a castle, and a strong defensive wall resting upon the rock, all well garnished with artillery. The French, in their enthusiasm of victory, could not be stopped even by these obstacles. Eight pieces of light artillery were brought forward, under cover of which the infantry charged and carried this strong position; so little do natural advantages avail when the minds of the assailants are influenced with an opinion that they are irresistible, and those of the defenders are depressed by a uniform and uninterrupted course of defeat. Six or seven thousand prisoners, and fifteen pieces of cannon captured, were the fruits of this splendid victory; and Massena the next morning took possession of Trent in the Tyrol, so long the stronghold where Wurmser had maintained his headquarters.[185] The wrecks of Davidowich's army fled deeper into the Tyrol, and took up their position at Lavisa, a small village on a river of a similar name, about three leagues to the northward of Trent, and situated in the principal road which communicates with Brixen and Inspruck. Buonaparte instantly pursued them with a division of his army, commanded by Vaubois, and passed the Lavisa with his cavalry, while the enemy were amused with an assault upon the bridge. Thus he drove them from their position, which, being the entrance of one of the chief defiles of the Tyrol, it was of importance to secure, and it was occupied accordingly by Vaubois with his victorious division. [Sidenote: THE TYROL.] Buonaparte, in consequence of his present condition, became desirous to conciliate the martial inhabitants of the Tyrol, and published a proclamation, in which he exhorted them to lay down their arms, and return to their homes; assuring them of protection against military violence, and labouring to convince them, that they had themselves no interest in the war which he waged against the Emperor and his government, but not against his subjects.[186] That his conduct might appear to be of a piece with his reasoning, Napoleon issued an edict, disuniting the principality of Trent from the German empire, and annexing it in point of sovereignty to the French Republic, while he intrusted, or seemed to intrust, the inhabitants themselves with the power of administering their own laws and government.
