Buonaparte soon after showed that he was serious in his design of enlarging the Cisalpine republic, as opportunity could be made to serve. There are three valleys, termed the Valteline districts, which run down from the Swiss mountains towards the lake of Como. The natives of the Valteline are about one hundred and sixty thousand souls. They speak Italian, and are chiefly of the Catholic persuasion. These valleys were at this period the subjects of the Swiss Cantons, called the Grisons, not being a part of their league, or enjoying any of their privileges, but standing towards the Swiss community, generally and individually, in the rank of vassals to sovereigns. This situation of thraldom and dependence was hard to endure, and dishonourable in itself; and we cannot be surprised that, when the nations around them were called upon to enjoy liberty and independence, the inhabitants of the Valteline should have driven their Swiss garrisons out of their valleys, adopted the symbol of Italian freedom, and carried their complaints against the oppression of their German and Protestant masters to the feet of Buonaparte. The inhabitants of the Valteline unquestionably had a right to assert their natural liberty, which is incapable of suffering prescription; but it is not equally clear how the French could, according to the law of nations, claim any title to interfere between them and the Grisons, with whom, as well as with the whole Swiss Union, they were in profound peace. This scruple seems to have struck Buonaparte's own mind.[298] He pretended, however, to assume that the Milanese government had a right to interfere, and his mediation was so far recognised, that the Grisons pleaded before him in answer to their contumacious vassals. Buonaparte gave his opinion, by advising the canton of the Grisons, which consists of three leagues, to admit their Valteline subjects to a share of their franchises, in the character of a fourth association. The moderation of the proposal may be admitted to excuse the irregularity of the interference.
