It is to him Russia owes, in the founding of Odessa, one of her most precious commercial centres. Up to that period, the duke was only distinguished for his military exploits. Having been sent to the shores of the Black Sea by Emperor Alexander, who understood all the importance of the site, Richelieu displayed in his fresh sphere of activity the greatest talent, from an administrative standpoint. In a few years, a harbour without life, and a few houses without tenants, were replaced by an accessible and spacious port and a rich and elegant town. The loyalty of his character contributed to draw around him merchants and colonisers. In spite of the plague and of the suspension of all commercial operations, Odessa, under his firm and enlightened administration, instead of declining, increased each day in prosperity. At present it is one of the most important points of the East. Thereafter, M. de Richelieu passed from the government of the Taurida to that of his own country. He hesitated for a long while before assuming a burden he fancied to be beyond his strength, and only yielded at the repeated instances of Emperor Alexander. Obliged, in virtue of his office, to sign the disastrous treaties of 1815, he bore with patriotic fortitude their odious consequences. Students of history will remember his efforts at the Congress of Aix-la-Chapelle (1818), and the happy results which crowned them. History may not, perhaps, acquiesce in his sufficient knowledge of the men and places which he had governed, but she will always refer with grateful remembrance to his sterling virtues and his exalted patriotism. The conversation became general, and followed the direction given to it by the personages, interesting in so many respects, taking part in it. M. Pozzo di Borgo, whom I saw on that occasion for the first time, seemed to me to unite the finesse, the liveliness of intellect, and the imagination of his countrymen. An avowed enemy of Bonaparte since the beginning of his career, he had never disguised his joy at the latter’s fall. In a few words he summed up all the causes which were inevitably to lead to the acceleration of that great catastrophe.[37]
