She purchased, at a high price, the libraries of D'Alembert, and of Voltaire, immediately after the death of those illustrious men. She also purchased the valuable cabinet of
natural curiosities collected by Professor Pallas. The most accomplished engineers she could obtain were sent to explore the mountains of Caucasus, and even to the frontiers of China. When we consider the trackless deserts to be explored, the inhospitable climes and barbarous nations to be encountered, these were enterprises far more perilous than the circumnavigation of the globe. The scientific expedition to China was escorted by a corps of eight hundred and ten chosen men, led by one hundred and seven distinguished officers. The savans were provided with every thing which could be thought of to promote their comfort and to aid them in their explorations, and three years were alloted as the probable term of service required by the mission. At the same time a naval expedition was fitted out to explore the northern seas, and ascertain the limits of the Russian empire. But the greatest work of Catharine's reign was the completion of the canal which united the waters of the Volga and the Neva, and thus established an inland navigation through all the countries which lie between the Caspian Sea and the Baltic.
In the year 1786 the empress announced her intention of making a magnificent journey to the Crimea, in order to be crowned sovereign of her new conquests. This design was to be executed in the highest style of oriental pomp, as the empress was resolved to extend her sway over all the nations of the Tartars. But the Tartars of those unmeasured realms, informed of the contemplated movement, were alarmed, and immediately combined their energies for a determined resistance. The Grand Seignior was also goaded to the most desperate exertions, for the empress had formed the design, and the report was universally promulgated, of placing her second grandchild, Constantine, on the throne of Constantinople.
The empress set out on her triumphal journey to the Crimea, on the 18th of January, 1787, accompanied by a magnificent suite. The sledges, large, commodious and so lined with furs as to furnish luxurious couches for repose,
traveled night and day. Relays of horses were collected at all the stations and immense bonfires blazed at night all along the road. Twenty-one days were occupied in the journey to Kief, where the empress was met by all the nobles of that portion of the empire. Here fifty magnificent galleys, upon the ice of the Dnieper, awaited the arrival of the empress and the opening of the river. On the 6th of May the ice was gone, the barges were afloat, and the empress with her suite embarked. The King of Poland, who had now assumed his old name of Count Poniatowski, here met, in the barge of the empress, his rival, Stanislaus Augustus.
The passage down the river, in this lovely month of spring, was like a fairy scene. The banks of the Dnieper were lined with villages constructed for the occasion. Peasants, in the most picturesque costumes, tended their flocks, or attended to various industrial arts as the flotilla drifted by. The Emperor of Germany, Joseph II., met the empress at Kaidak, from whence they proceeded together, by land, to Kherson. Here Catharine lodged in a palace where a throne had been erected for the occasion which cost fourteen thousand dollars. The whole expense of this one journey exceeded seven millions of dollars. From Kherson the empress proceeded to the inland part of the Crimean peninsula. Her body guard consisted of an army of one hundred and fifty thousand men, stationed at but a short distance from her. The entertainments in the Crimea were of the most gorgeous character, and were arranged without any regard to expense. On the return of the empress she reached St. Petersburg the end of July, having been absent six months and four days. All Europe was surprised at the supineness which the sultan had manifested in allowing Catharine to prosecute her journey unobstructed; but Turkey was not then prepared for the commencement of hostilities.
A squadron of thirty ships of war soon sailed from Constantinople and entered the Euxine. The Turks were apprehensive
that the Greeks might rise and disarmed them all before commencing the campaign. The empress had equipped, at Azof and Kherson, eight ships of the line, twelve frigates, and two hundred gun-boats. She had, in addition, a large squadron at Cronstadt, ready to sail for the Mediterranean. Eighty thousand soldiers were also on the march from Germany to Moldavia. Every thing indicated that the entire overthrow of the Ottoman empire was at hand.
The thunders of battle soon commenced on the sea and on the land. Both parties fought with desperation. Russia and Austria endeavored to unite France with them, in the attempt to dismember the Turkish empire as Poland had been partitioned, but France now stood in dread of the gigantic growth both of Russia and of Austria, and was by no means disposed to strengthen those powers. England was also secretly aiding the Turks and sending them supplies. Influenced by the same jealousy against Russia, Sweden ventured to enter into an alliance with the Turks, while Prussia, from the same motive, secretly lent Gustavus III. money, and England sent him a fleet. Thus, all of a sudden, new and appalling dangers blazed upon Russia. So many troops had been sent to the Crimea that Catharine was quite unprepared for an attack from the Swedish frontier.
The Grand Duke Paul begged permission of his mother that he might join the army against the Turks. The empress refused her consent.
