In the west he touched the dominions of Mohammed, sultan of Carizme, who reigned from the Persian Gulf to the borders of India and Turkestan; and who, in the proud imitation of Alexander the Great, forgot the servitude and ingratitude of his fathers to the house of Seljuk. It was the wish of Zingis to establish a friendly and commercial intercourse with the most powerful of the Moslem princes; nor could he be tempted by the secret solicitations of the caliph of Bagdad, who sacrificed to his personal wrongs the safety of the Church and state. A rash and inhuman deed provoked and justified the Tartar arms in the invasion of the southern Asia. A caravan of three ambassadors and one hundred and fifty merchants was arrested and murdered at Otrar, by the command of Mohammed; nor was it till after a demand and denial of justice, till he had prayed and fasted three nights on a mountain, that the Mogul emperor appealed to the judgment of God and his sword. Our European battles, says a philosophic writer, are petty skirmishes, if compared to the numbers that have fought and fallen in the fields of Asia. Seven hundred thousand Moguls and Tartars are said to have marched under the standard of Zingis and his four sons. In the vast plains that extend to the north of the Sihon or Jaxartes, they were encountered by four hundred thousand soldiers of the sultan; and in the first battle, which was suspended by the night, one hundred and sixty thousands Carizmians were slain. The Persian historians will relate the sieges and reduction of Otrar, Cogende, Bochara, Samarcand, Carizme, Herat, Merou, Nisabour, Balch, and Candahar; and the conquest of the rich and populous countries of Transoxiana, Carizme, and Chorasan. The destructive hostilities of Attila and the Huns have long since been elucidated by the example of Zingis and the Moguls; and in this more proper place I shall be content to observe, that, from the Caspian to the Indus, they ruined a tract of many hundred miles, which was adorned with the habitations and labors of mankind, and that five centuries have not been sufficient to repair the ravages of four years. The Mogul conqueror yielded with reluctance to the murmurs of his weary and wealthy troops, who sighed for the enjoyment of their native land. Incumbered with the spoils of Asia, he slowly measured back his footsteps, betrayed some pity for the misery of the vanquished, and declared his intention of rebuilding the cities which had been swept away by the tempest of his arms. After he had repassed the Oxus and Jaxartes, he was joined by two generals, whom he had detached with thirty thousand horse to subdue the western provinces of Persia. They had trampled on the nations which opposed their passage, penetrated through the gates of Derbend, traversed the Volga and the Desert, and accomplished the circuit of the Caspian Sea, by an expedition which had never been attempted and has never been repeated.
