It was on the banks of the Ganges that Timour was informed, by his speedy messengers, of the disturbances which had arisen on the confines of Georgia and Anatolia, of the revolt of the Christians, and the ambitious designs of the sultan Bajazet. His vigor of mind and body was not impaired by sixty-three years, and innumerable fatigues; and, after enjoying some tranquil months in the palace of Samarcand, he proclaimed a new expedition of seven years into the western countries of Asia. [27] To the soldiers who had served in the Indian war he granted the choice of remaining at home, or following their prince; but the troops of all the provinces and kingdoms of Persia were commanded to assemble at Ispahan, and wait the arrival of the Imperial standard. It was first directed against the Christians of Georgia, who were strong only in their rocks, their castles, and the winter season; but these obstacles were overcome by the zeal and perseverance of Timour: the rebels submitted to the tribute or the Koran; and if both religions boasted of their martyrs, that name is more justly due to the Christian prisoners, who were offered the choice of abjuration or death. On his descent from the hills, the emperor gave audience to the first ambassadors of Bajazet, and opened the hostile correspondence of complaints and menaces, which fermented two years before the final explosion. Between two jealous and haughty neighbors, the motives of quarrel will seldom be wanting. The Mogul and Ottoman conquests now touched each other in the neighborhood of Erzeroum, and the Euphrates; nor had the doubtful limit been ascertained by time and treaty. Each of these ambitious monarchs might accuse his rival of violating his territory, of threatening his vassals, and protecting his rebels; and, by the name of rebels, each understood the fugitive princes, whose kingdoms he had usurped, and whose life or liberty he implacably pursued. The resemblance of character was still more dangerous than the opposition of interest; and in their victorious career, Timour was impatient of an equal, and Bajazet was ignorant of a superior. The first epistle [28] of the Mogul emperor must have provoked, instead of reconciling, the Turkish sultan, whose family and nation he affected to despise. [29] "Dost thou not know, that the greatest part of Asia is subject to our arms and our laws? that our invincible forces extend from one sea to the other? that the potentates of the earth form a line before our gate? and that we have compelled Fortune herself to watch over the prosperity of our empire. What is the foundation of thy insolence and folly? Thou hast fought some battles in the woods of Anatolia; contemptible trophies! Thou hast obtained some victories over the Christians of Europe; thy sword was blessed by the apostle of God; and thy obedience to the precept of the Koran, in waging war against the infidels, is the sole consideration
