Through the first half of 1215, the Year of the Pig, the Mongols slowly set out with caravans of people, animals, and goods from the smoldering ruins of Zhongdu to the high, arid plateau of Inner Mongolia. They gathered again at Dolon Nor, where Genghis Khan had waited unsuccessfully to cross back home one year earlier, and they waited for the summer to pass before venturing across the Gobi. Genghis Khan had, once again, shown his ability to win in war, and now he demonstrated, on a scale unprecedented in the history of steppe khans, his ability to bring the goods home to his people.
A river of brightly colored silk flowed out of China. It was as though Genghis Khan had rerouted all the different twisting channels of the Silk Route, combined them into one large stream, and redirected it northward to spill out across the Mongol steppes. The caravans of camels and oxcarts carried so much of the precious cloth that the Mongols used silk to wrap their other goods and as packing material. They threw away their rawhide ropes and used twisted cords of silk instead. They bundled robes embroidered with silver and golden thread in the designs of blooming peonies, flying cranes, breaking waves, and mythical beasts, and they packed silk slippers sewn with tiny pearls. The Mongols filled carts with silk rugs, wall hangings, pillows, cushions, and blankets, as well as silk sashes, braid, fringe, and tassels. They carried bolts of raw silk, silken threads, and cloth worked into every imaginable type of clothing or decorations and in more colors than the Mongol language could identify.
In addition to silk, satin, brocade, and gauze, the bundles contained whatever objects the Mongol eye fancied and could be moved, including lacquered furniture, paper fans, porcelain bowls, metal armor, bronze knives, wooden puppets, iron kettles, brass pots, board games, and carved saddles. The Mongols carried jugs of perfume and makeup made from ocher, yellow lead, indigo, flower extracts, fragrant waxes, balsam, and musk. They brought hair ornaments and jewelry crafted from precious metals, ivory, or tortoiseshell and studded with turquoise, pearls, cornelian, coral, lapis lazuli, emeralds, and diamonds. Wagons loaded with skins of wine, casks of honey, and bricks of black tea followed camels that smelled of incense, medicines, aphrodisiacs, and special woods of cinnabar, camphor, and sandalwood.
Long lines of clerks laboriously cataloged, checked, and rechecked the goods of each caravan of camels and oxcarts. Musicians played and sang to delight their captors as the caravan moved. Whenever the caravan paused, acrobats, contortionists, and jugglers performed while young girls gathered dried dung for the fire, milked the animals, cooked a meal, and offered whatever else might be asked of them. Boys tended the animals and lifted the heavy loads. Behind the animals came the endless lines of marching captives—thousands upon thousands. Princes and priests. Tailors and pharmacists. Translators and scribes. Astrologers and jewelers. Artists and soothsayers. Magicians and goldsmiths. Anyone evidencing a skill had been rounded up, together with those who merely attracted the attention of one of the Mongols for whatever reason or fancy.
In all the centuries of raiding and trading, no leader had brought back to his homeland nearly the amount of goods as Genghis Khan. But vast as the quantities were, the appetites of his own people were insatiable. As he returned from his campaigns, his caravans were laden with valuable goods, but each load created the desire for yet more. Every Mongol could sit in his ger on lacquered furniture draped in silk; every maiden was perfumed, painted with makeup, and bejeweled. Every riding horse was fixed with metal fittings, and every warrior with bronze and iron weapons. To work their crafts, the thousands of new craftsmen needed more raw materials—everything from wood, clay, and cloth to bronze, gold, and silver. To feed these workers, constant supplies of barley, wheat, and other food commodities had to be hauled across the vast wasteland separating the herders’ pastures and the agricultural fields of the south; and the more captives Genghis Khan brought home, the more food and equipment he had to obtain to supply them. Novelties became necessities, and each caravan of cargo stimulated a craving for more. The more he conquered, the more he had to conquer.
The steppes could no longer be isolated. Genghis Khan had to organize supply lines, maintain production, and coordinate the movement of goods and people on an unprecedented scale. What began as a quick raid on cities south of the Gobi for silks and baubles had turned into three decades of the most extensive war in world history. Genghis Khan would spend the next fifteen years of his life fighting across the face of Asia, and at his death, he bequeathed the war to his descendants to expand into new countries and against new people for two more generations.
After the Jurched campaigns, the Great Khan returned directly to his steppes of Khodoe Aral between the Kherlen and the Tsenker Rivers. In keeping with his prior practices, Genghis Khan immediately began to distribute the accumulated booty to his generals and officers, who in turn made the appropriate divisions among their own men. For the first time in his career, however, he simply had too much loot and material to distribute, and he needed to find ways to administer it and store it until needed. To solve this problem of affluence, Genghis Khan allowed the construction of some buildings. He situated them near the small Avarga Stream, somewhat to the side of the steppe where a spring bubbled up out of the ground. According to tradition, Borte treated her young son Ogodei with the water from this spring in order to cure a disease. Collectively, the buildings were named the Yellow Palace, and they served mostly as warehouses for the goods brought back from the campaigns. With rivers on both sides and a small clump of hills in the middle, the area was easily protected, and made a surprise attack virtually impossible.
After his long absence, Genghis Khan had many pending problems to solve, not only among his Mongol subjects, but also with the Siberian tribes of the north and the Uighur farmers of the south. Some of the Siberian tribes that had first submitted to Mongol rule during Jochi’s invasion of 1207 used Genghis Khan’s lengthy absence on the Jurched campaign to quit sending tributary furs, forest products, and young women. When a Mongol envoy arrived to investigate, however, he found that in keeping with the fame of their women, they now had a woman chief whom they called Botohui-tarhun, a name that meant roughly Big and Fierce. Rather than surrender thirty maidens to the Mongols as wives, she took the Mongol himself captive. When the messenger did not return, Genghis Khan eventually sent another negotiator, and she took him captive as well.
In 1219, the Year of the Hare, Genghis Khan sent a trusted general with a detachment of good soldiers to find out what had happened. Accustomed to campaigning on the open steppes and in the farmlands, the Mongols had little experience fighting or traveling in the dense forest. Usually, the Mongols crossed the steppe by spreading out and moving forward on a broad front. In the forest, however, they had to follow one another along the narrow trails. Botohui-tarhun’s forces heard them coming long before they arrived in her territory, and like any experienced forest hunter, she set a trap for them. She sent a contingent of her troops to seal off the trail behind the men to prevent their escape, then she ambushed them from the front. Botohui-tarhun’s forces triumphed—and in the battle, her warriors killed the Mongol general.
Such a loss was highly unusual, and it enraged Genghis Khan. At first, he threatened to lead the army himself in vengeance against the victorious queen. His advisers soon convinced him otherwise. They prepared a large expedition, and this time the Mongols were determined to win by whatever means necessary. A small detachment of Mongol warriors moved out as a decoy pretending to guard the frontier trail and passes between the Mongols and the queen’s territory. Meanwhile, the Mongol soldiers in the main force of the army secretly cut a new road through the forest from another direction. With axes, adzes, saws, chisels, and all the tools and weapons they could muster, the Mongols laboriously cleared a path by following the mountain trail of the “red bull,” probably the large reddish deer or elk. After completing the secret road, the Mongol soldiers swooped down on the queen’s headquarters so fast that in the words of the Secret History, it seemed as though they had descended “through the top of the smoke-holes of their tents.”
