On the same day Bonaparte signed at Milan a treaty of alliance with the envoys of the new Venetian Government. His friendship was to be dearly bought. In secret articles, which were of more import than the vague professions of amity which filled the public document, it was stipulated that the French and Venetian Republics should come to an understanding as to the _exchange_ of certain territories, that Venice should pay a contribution in money and in materials of war, should aid the French navy by furnishing three battleships and two frigates, and should enrich the museums of her benefactress by 20 paintings and 500 manuscripts. While he was signing these conditions of peace, the Directors were despatching from Paris a declaration of war against Venice. Their decision was already obsolete: it was founded on Bonaparte's despatch of April 30th; but in the interval their proconsul had wholly changed the situation by overthrowing the rule of the Doge and Senate, and by setting up a democracy, through which he could extract the wealth of that land. The Directors' declaration of war was accordingly stopped at Milan, and no more was heard of it. They were thus forcibly reminded of the truth of his previous warning that things would certainly go wrong unless they consulted him on all important details.[80] This treaty of Milan was the fourth important convention concluded by the general, who, at the beginning of the campaign of 1796, had been forbidden even to sign an armistice without consulting Salicetti!
