The empire seems at this time to have been at the height of its splendor, and historians, as well as students and readers of history, have been fortunate in possessing the shrewd and candid observations of Marco Polo, whose unique narratives still preserve their simple charm, nowise impaired by comparison with our stricter historical methods.
It is our desire to treat of the great and admirable achievements of the Grand Khan now reigning, who is styled Kublai Khan; the latter word implying, in our language, lord of lords, and with much propriety added to his name; for in respect to number of subjects, extent of territory, and amount of revenue he surpasses every sovereign that has heretofore been or that now is in the world; nor has any other been served with such implicit obedience by those whom he governs.
Kublai Khan is the lineal and legitimate descendant of Genghis Khan, the first emperor, and the rightful sovereign of the Tartars. He obtained the sovereignty by his consummate valor, his virtues, and his prudence, in opposition to the designs of his brothers, supported by many of the great officers and members of his own family. But the succession appertained to him of right. It is forty-two years since he began to reign, and he is fully eighty-five years of age. Previously to his ascending the throne he had served as a volunteer in the army, and endeavored to take a share in every enterprise. Not only was he brave and daring in action, but in point of judgment and military skill he was considered to be the most able and successful commander that ever led the Tartars to battle. From that period, however, he ceased to take the field in person, and intrusted the conduct of expeditions to his sons and his captains; excepting in one instance, the occasion of which was as follows.
A certain chief named Nayan, who, although only thirty years of age, was kinsman to Kublai, had succeeded to the dominion of many cities and provinces, which enabled him to bring into the field an army of four hundred thousand horse. His predecessors, however, had been vassals of the Grand Khan. Actuated by youthful vanity upon finding himself at the head of so great a force, he formed, in the year 1286, the design of throwing off his allegiance, and usurping the sovereignty. With this view he privately despatched messengers to Kaidu, another powerful chief, whose territories lay toward the greater Turkey, and who, although a nephew of the Grand Khan, was in rebellion against him, and bore him determined ill-will, proceeding from the apprehension of punishment for former offences. To Kaidu, therefore, the propositions made by Nayan were highly satisfactory, and he accordingly promised to bring to his assistance an army of a hundred thousand horse. Both princes immediately began to assemble their forces, but it could not be effected so secretly as not to come to the knowledge of Kublai, who, upon hearing of their preparations, lost no time in occupying all the passes leading to the countries of Nayan and of Kaidu, in order to prevent them from having any information respecting the measures he was himself taking.
He then gave orders for collecting, with the utmost celerity, the whole of the troops stationed within ten days' march of the city of Kambalu. These amounted to three hundred and sixty thousand horse, to which was added a body of a hundred thousand foot, consisting of those who were usually about his person, and principally his falconers and domestic servants. In the course of twenty days they were all in readiness. Had he assembled the armies kept up for the constant protection of the different provinces of Cathay, it must necessarily have required thirty or forty days; in which time the enemy would have gained information of his arrangements, and been enabled to effect their junction, and to occupy such strong positions as would best suit with their designs. His object was, by promptitude, which is ever the companion of victory, to anticipate the preparations of Nayan, and, by falling upon him while single, destroy his power with more certainty and effect than after he should have been joined by Kaidu.
In every province of Cathay and of Manji,[65] as well as in other parts of his dominions, there were many disloyal and seditious persons, who at all times were disposed to break out in rebellion against their sovereign, and on this account it became necessary to keep armies in such of the provinces as contained large cities and an extensive population, which are stationed at the distance of four or five miles from those cities, and can enter them at their pleasure. These armies the Grand Khan makes it a practice to change every second year, and the same with respect to the officers who command them. By means of such precautions the people are kept in quiet subjection, and no movement nor innovation of any kind can be attempted. The troops are maintained not only from the pay they receive out of the imperial revenues of the province, but also from the cattle and their milk, which belong to them individually, and which they send into the cities for sale, furnishing themselves from thence, in return, with those articles of which they stand in need. In this manner they are distributed over the country, in various places, to the distance of thirty, forty, and even sixty days' journey. If even the half of these corps were to be collected in one place, the statement of their number would appear marvellous and scarcely entitled to belief.
Having formed his army in the manner above described, the Grand Khan proceeded toward the territory of Nayan, and by forced marches, continued day and night, he reached it at the expiration of twenty-five days. So prudently, at the same time, was the expedition managed, that neither that Prince himself nor any of his dependents were aware of it, all the roads being guarded in such a manner that no persons who attempted to pass could escape being made prisoners. Upon arriving at a certain range of hills, on the other side of which was the plain where Nayan's army lay encamped, Kublai halted his troops and allowed them two days of rest. During this interval he called upon his astrologers to ascertain, by virtue of their art, and to declare in presence of the whole army, to which side the victory would incline. They pronounced that it would fall to the lot of Kublai. It has ever been the practice of the grand khans to have recourse to divination for the purpose of inspiriting their men.
Confident, therefore, of success, they ascended the hill with alacrity the next morning, and presented themselves before the army of Nayan, which they found negligently posted, without advanced parties or scouts, while the chief himself was asleep in his tent, accompanied by one of his wives. Upon awaking, he hastened to form his troops in the best manner that circumstances would allow, lamenting that his junction with Kaidu had not been sooner effected. Kublai took his station in a large wooden castle, borne on the backs of four elephants, whose bodies were protected with coverings of thick leather hardened by fire, over which were housings of cloth of gold. The castle contained many cross-bowmen and archers, and on the top of it was hoisted the imperial standard, adorned with representations of the sun and moon. His army, which consisted of thirty battalions of horse, each battalion containing ten thousand men, armed with bows, he disposed in three grand divisions; and those which formed the left and right wings he extended in such a manner as to outflank the army of Nayan. In front of each battalion of horse were placed five hundred infantry, armed with short lances and swords, who, whenever the cavalry made a show of fight, were practised to mount behind the riders and accompany them, alighting again when they returned to the charge, and killing, with their lances, the horses of the enemy. As soon as the order of battle was arranged, an infinite number of wind instruments of various kinds were sounded, and these were succeeded by songs, according to the custom of the Tartars before they engage in fight, which commences upon the signal given by the cymbals and drums, and there was such a beating of the cymbals and drums, and such singing, that it was wonderful to hear. This signal, by the orders of the Grand Khan, was first given to the right and left wings; and then a fierce and bloody conflict began. The air was instantly filled with a cloud of arrows that poured down on every side, and vast numbers of men and horses were seen to fall to the ground.
The loud cries and shouts of the men, together with the noise of the horses and the weapons, were such as to inspire terror in those who heard them. When their arrows had been discharged, the hostile parties engaged in close combat with their lances, swords, and maces shod with iron; and such was the slaughter, and so large were the heaps of the carcasses of men, and more especially of horses, on the field, that it became impossible for the one party to advance upon the other. Thus the fortune of the day remained for a long time undecided, and victory wavered between the contending parties from morning until noon; for so zealous was the devotion of Nayan's people to the cause of their master, who was most liberal and indulgent toward them, that they were all ready to meet death rather than turn their backs to the enemy. At length, however, Nayan, perceiving that he was nearly surrounded, attempted to save himself by flight, but was presently made prisoner, and conducted to the presence of Kublai, who gave orders for his being put to death. This was carried into execution by enclosing him between two carpets, which were violently shaken until the spirit had departed from the body; the motive for this peculiar sentence being that the sun and the air should not witness the shedding of the blood of one who belonged to the imperial family. Those of his troops which survived the battle came to make their submission and swear allegiance to Kublai.
Nayan, who had privately undergone the ceremony of baptism, but never made open profession of Christianity, thought proper, on this occasion, to bear the sign of the cross in his banners, and he had in his army a vast number of Christians, who were among the slain. When the Jews and the Saracens perceived that the banner of the cross was overthrown, they taunted the Christian inhabitants with it, saying: "Behold the state to which your (vaunted) banners, and those who followed them, are reduced!" On account of these derisions the Christians were compelled to lay their complaints before the Grand Khan, who ordered the former to appear before him, and sharply rebuked them. "If the cross of Christ," he said, "has not proved advantageous to the party of Nayan, the effect has been consistent with reason and justice, inasmuch as he was a rebel and a traitor to his lord, and to such wretches it could not afford its protection. Let none therefore presume to charge with injustice the God of the Christians, who is himself the perfection of goodness and of justice."
