Peter upon this sent to demand satisfaction of the emperor Hussein, who was then disputing the throne with the rebel Mahmoud, who had usurped it, and likewise of Mahmoud himself. The former of these was willing to do the czar justice, the other refused it; Peter therefore resolved to right himself, and take advantage of the distractions in the Persian empire.

Mir-Mahmoud still pushed his conquests in Persia. The sophi hearing that the emperor of Russia was preparing to enter the Caspian Sea, in order to revenge the murder of his subjects at Shamache, made private application to him, by means of an Armenian, to take upon him at the same time the defence of Persia.

Peter had for a considerable time formed a project to make himself master of the Caspian Sea, by means of a powerful naval force, and to turn the tide of commerce from Persia and a part of India through his own dominions. He had caused several parts of this sea to be sounded, the coasts to be surveyed, and exact charts made of the whole. He then set sail for the coast of Persia the 15th day of May, 1722. Catherine accompanied him in this voyage, as she had done in the former. They sailed down the Wolga as far as the city of Astracan. From thence he hastened to forward the canals which were to join the Caspian, the Baltic, and the Euxine seas, a work which has been since executed in part under the reign of his grandson.

While he was directing these works, the necessary provisions for his expedition were arrived in the Caspian Sea. He was to take with him twenty-two thousand foot, nine thousand dragoons, fifteen thousand Cossacks, and three thousand seamen, who were to work the ships, and occasionally assist the soldiery in making descents on the coast. The horse were to march over land through deserts where there was frequently no water to be had, and afterwards to pass over the mountains of Caucasus, where three hundred men are sufficient to stop the progress of a whole army; but the distracted condition in which Persia then was, warranted the most hazardous enterprises.

The czar sailed about a hundred leagues to the southward of Astracan, till he came to the little town of Andrewhoff. It may appear extraordinary to hear of the name of Andrew on the coasts of the Hyrcanian Sea; but some Georgians, who were formerly a sect of Christians, had built this town, which the Persians afterwards fortified; but it fell an easy prey to the czar's arms. From thence he continued advancing by land into the province of Daghestan, and caused manifestoes to be circulated in the Turkish and Persian languages.[115] It was necessary to keep fair with the Ottoman Porte, who reckoned among its subjects, not only the Circassians and Georgians, who border upon this country, but also several powerful vassals, who had of late put themselves under the protection of the grand seignior.

Among others there was one very powerful, named Mahmoud d'Utmich, who took the title of sultan, and had the courage to attack the czar's troops, by which he was totally defeated, and the story says, that his whole country was made a bonfire on the occasion.

Sept. 14, 1722.] In a short time afterwards Peter arrived at the city of Derbent, by the Persians and Turks called Demir Capi, that is, the Iron Gate, and so named from having formerly had an iron gate at the south entrance. The city is long and narrow, its upper part joins to a rocky branch of Mount Caucasus, and the walls of the lower part are washed by the sea, which in violent storms make a breach over them. These walls might pass for one of the wonders of antiquity, being forty feet in height, and six in breadth, defended with square towers at the distance of every fifty feet. The whole work seems one uniform piece, and is built of a sort of brown free-stone mixed with pounded shells, which served as mortar, so that the whole forms a mass harder than marble. The city lies open from the sea, but part of it next the land appears impregnable. There are still some ruins of an old wall like that of China, which must have been built in the earliest times of antiquity, and stretched from the borders of the Caspian Sea to the Pontus Euxinus; and this was probably a rampart raised by the ancient kings of Persia against those swarms of barbarians which dwelt between those two seas.

According to the Persian tradition, the city of Derbent was partly repaired and fortified by Alexander the Great. Arrian and Quintus Curtius tell us, that Alexander absolutely rebuilt this city. They say indeed that it was on the banks of the Tanais or Don, but then in their time the Greeks gave the name of Tanais to the river Cyrus, which runs by the city. It would be a contradiction to suppose that Alexander should build a harbour in the Caspian Sea, on a river that opens into the Black Sea.

There were formerly three or four other ports in different parts of the Caspian Sea, all which were probably built with the same view; for the several nations inhabiting to the west, east, and north of that sea, have in all times been barbarians, who had rendered themselves formidable to the rest of the world, and from hence principally issued those swarms of conquerors who subjugated Asia and Europe.

And here I must beg leave to remark, how much pleasure authors in all ages have taken to impose upon mankind, and how much they have preferred a vain show of eloquence to matter of fact. Quintus Curtius puts into the mouths of Scythians an admirable speech full of moderation and philosophy, as if the Tartars of those regions had been all so many sages, and that Alexander had not been the general nominated by the Greeks against the king of Persia, sovereign of the greatest part of southern Scythia and the Indies. Other rhetoricians, thinking to imitate Quintus Curtius, have studied to make us look upon those savages of Caucacus and its dreary deserts, who lived wholly upon rapine and bloodshed, as the people in the world most remarkable for austere virtue and justice, and have painted Alexander, the avenger of Greece, and the conqueror of those who would have enslaved him and his country, as a public robber, who had ravaged the world without justice or reason.
