The misfortunes of the unhappy young Princess Tarrakanoff supply M. Blanc with materials for the most interesting chapter in this volume of his work. The Empress Elizabeth, daughter of Peter the Great, and predecessor of Peter III.--whose marriage with the Princess of Anhalt Zerbest, afterwards Catherine the Great, was brought about by her--had had three children by her secret marriage with Alexis Razumoffski. The youngest of these was a daughter, who was brought up in Russia under the name of the Princess Tarrakanoff. When Catherine trampled the rights of Poland under foot, the Polish prince, Charles Radzivil, carried off the young princess, and took her to Italy, thinking to set her up at some future day as a pretender to the Russian throne. Informed of this, Catherine confiscated his estates; and in order to live, he was compelled to sell the diamonds and other valuables he had taken with him to Italy. These resources exhausted, Radzivil set out for Poland to seek others, leaving the young princess, then in her sixteenth year, at Rome, under the care of a sort of governess or duenna. On reaching his native country he was offered the restoration of his property if he would bring back his ward to Russia. He refused; but he was so base as to promise that he would take no further trouble about her, and leave her to her fate. Catherine pardoned him, and forthwith put Alexis Orloff on the scent. He was a keen bloodhound, she well knew, capable of any villany that might serve his ambition. Gold unlimited was placed at his disposal, and promise of high reward if he discovered the retreat of the princess, and lured her within Catherine's reach. Orloff set out for Italy; and on arriving there he took into his employ a Neapolitan named Ribas, a sort of spy, styling himself a naval officer, who pledged himself to find out the princess, but stipulated for rank in the Russian navy as his reward. M. Blanc asserts that he demanded to be made admiral at once; and that Orloff, afraid, notwithstanding the extensive powers given him, to bestow so high a grade, or compelled by the suspicions of Ribas to produce the commission itself, wrote to Catherine, who at once sent the required document. Whether this be exact or not, more than one historian mentions that Ribas subsequently commanded in the Black Sea as a Russian vice-admiral. When certain of his reward, Ribas, who then had spent two months in researches, revealed the retreat of the unfortunate princess. With some abridgment we will follow M. Blanc, whose narrative agrees, in all the main points, with the most authentic versions of this touching and romantic history.
