It will be remembered, that, in exchange for the cession of Flanders, and of all the countries on the left side of the Rhine, including the strong city of Mayence, which she was to yield up to France in perpetuity, Austria stipulated an indemnification on some other frontier. The original project bore, that the Lombardic republic, since termed the Cisalpine, should have all the territories extending from Piedmont to the river Oglio. Those to the eastward of that river were to be ceded to Austria as an equivalent for the cession of Belgium, and the left bank of the Rhine. The Oglio, rising in the Alps, descends through the fertile districts of Brescia and Cremasco, and falls into the Po near Borgo-forte, enclosing Mantua on its left bank, which strong fortress, the citadel of Italy, was, by this allocation, to be restored to Austria. There were farther compensations assigned to the Emperor, by the preliminaries of Leoben. Venice was to be deprived of her territories on the mainland, which were to be confiscated to augment the indemnity destined for the empire; and this, although Venice, as far as Buonaparte yet knew, had been faithful to the neutrality she had adopted. To redeem this piece of injustice, another was to be perpetrated. The state of Venice was to receive the legations of Bologna, Ferrara, and Romagna, in lieu of the dominions which she was to cede to Austria; and these legations, it must not be forgotten, were the principal materials of the Cispadane republic, founded by Buonaparte himself. These, however, with their population, which he had led to hope for a free popular government, he was now about to turn over to the dominion of Venice, the most jealous oligarchy in the world, which was not likely to forgive those who had been forward in expressing a desire of freedom. This was the first concoction of the treaty of Leoben, from which it appears that the negotiators of the two great powers regarded the secondary and weaker states, whether ancient or of modern erection, merely as make-weights, to be thrown into either scale, as might be necessary to adjust the balance.
