Zavkhan lay north across the Gobi from the oasis where Ismayil had his stronghold, and it was difficult for him to cross such a vast, dry expanse with a large army. For him to make a campaign so far away from his base would have attracted the attention of the Ming army along the Chinese frontier, and they might have seized the oases that they claimed, but which he controlled. If he lost control over the oases, he would also have lost control of the Silk Route. He would have been left without a military or a commercial base.
Because he could not send in a large force to protect his claim on the Oirat territory, Ismayil sought to govern the Oirat by controlling their access to Chinese and Middle Eastern trade goods. Manduhai had no such material incentive with which to entice the Oirat. Nevertheless, from the time of Genghis Khan’s daughter Checheyigen, the Mongols and the Oirat had maintained close social and marriage ties. Manduhai came from the Choros clan of the Oirat, as did Dayan Khan’s great-grandfather Esen. In addition, many of Dayan Khan’s female ancestors had been Oirat of different clans.
The chronicles do not explain how Manduhai chose the area or how she came to have the strategic knowledge that she exhibited consistently throughout her military career. Did she know about the battles of Qaidu Khan and Khutulun? Had she learned about the techniques of Genghis Khan? Did she follow the direction of her best general, Une-Bolod? Or did she merely possess some kind of born genius for strategic thinking?
Manduhai’s expedition of conquest resulted in a number of moderately sized skirmishes, but few large battles. She found little opposition in the west. She came with the true khan, the descendant of Genghis Khan; even the most ardent supporter of the taishi knew that the Great Khan outranked him and that it was to the Great Khan that they owed their ultimate allegiance. Some of the Oirat sided with Manduhai from the start, and others eventually came to her side.
In the midst of one of the battles, Manduhai’s helmet slipped. This was her first military campaign, and she may not yet have been accustomed to the battlefield. Since craftsmen usually made helmets to fit men, her helmet likely was large on her head and insecure. The displaced helmet dangled briefly from her neck before falling away completely and landing in the dirt.
For any warrior, much less for a commander, only the loss of the horse would be more dangerous than the loss of the helmet. Without it, her head immediately became an open target for any Oirat who wanted to shoot her or attack her with a sword. But for her or one of her underlings to dismount to retrieve the helmet would be to face the even more dangerous prospect of being trampled under the hooves of either the enemy or her own soldiers.
An Oirat warrior was the first to notice the unfortunate loss. “The Queen has no helmet,” he called out. Such a cry almost certainly seemed like an invitation to mob her like wolves on a wounded deer, but instead of taking advantage of her unexpected vulnerability, the Oirat soldier shouted for someone to “bring another.” When it appeared obvious that no one had a spare helmet to offer, he removed his own helmet in the midst of the battle and presented it to her. The chronicles do not name the Oirat who, quite probably, saved her life; they only specify his ethnicity. She possibly had a contingent of Oirat fighting with her, or he could have been a chivalrous enemy warrior. No matter whether he had already joined Manduhai’s side or fought against her in the skirmish, the record of the incident showed the level of respect she maintained among the Oirat.
Manduhai cleverly managed to turn the loss of her helmet to her advantage. The headgear of a person is so closely associated with the soul and its heavenly protection, since the sky is seen as the hat of the Earth, that Mongols sometimes deliberately discard a hat as a way of changing that fate and striving for a new one. Realizing that the sight of the commander losing her helmet could frighten her followers enough to cause them to flee from the battle, Manduhai dashed forward even more boldly and fiercely, determined to demonstrate that her change of headdress promised certain victory. In the words of the Altan Tobci, her enemy reportedly swarmed at her as thick as a cloud of dust, but she fell upon them and “destroyed them entirely, and annihilated them.” She took prisoners beyond counting, and she killed their leaders who had been disloyal to her and Dayan Khan.
Victory was often marked by imposition of some relatively unimportant but symbolically meaningful laws on the defeated. The Yellow Chronicle of the Oirat (Shira Tughuji) listed several such punitive laws issued by Manduhai after her victory. She limited the crest on the Oirat helmets to a length of two fingers. They could not call any ger in their land an ordon, the Mongol word for palace; and when in the presence of khans, they had to sit on their knees.
The text also mentions a law that the Oirat could no longer eat with a knife but instead had to gnaw their meat. Such a law probably never existed, but Manduhai may have confiscated their knives as a security measure, thereby temporarily depriving them of knives for eating meat until they were again allowed to acquire them.
Manduhai had reunited the Mongols, and she now controlled the strategic area of Zavkhan, necessary to assert her power over the west. Without that control, she would face the dangers posed by a rebel tribe, foreign warlords, or even the possibility of wealthy merchants luring her followers away. Une-Bolod gave her control of the east, and now she had added control of the west.
In addition to its strategic importance, the western campaign against the Oirat was a notable propaganda victory, demonstrating that Manduhai had the blessing of the Shrine of the First Queen and the Eternal Blue Sky. Manduhai showed that she was in control of her country. The khan may have been a small boy in a box, but her strength and determination inspired confidence. For the first time in more than a century, a united and strong central government had control of Mongolia. Manduhai had succeeded in uniting western and eastern Mongolia under the Borijin clan for the first time since Elbeg Khan’s fateful encounter with the rabbit in 1399, nearly a century earlier.
Going to war in a basket box may have been an odd way for the young Dayan Khan to grow up, but after the trauma of his earliest years, Manduhai provided the boy with a stable and secure, albeit unusual, childhood. For much of the prior centuries, the domineering warlords had kept a sequence of boy khans as prisoners, whom they exploited, abused, and humiliated. The warlords certainly showed no interest in educating or preparing these boys for leadership because they would never lead. No one expected any of the boys to live to become a fully functioning adult, much less the ruling khan. At most, a boy might be required to reproduce a male heir before being dispatched, or some other male relatives could be substituted as khan or as progenitor.
From the start, Manduhai’s actions made clear that she planned for Dayan Khan to rule. He would be a fully functioning and ruling khan, not a figurehead. Manduhai could easily have left him under the charge of nurses or have built a small, isolated camp for him in one of the many canyons of the Gobi or the Altai Mountains. She could have sent him to live in the remote steppe where she had lived with her first husband, Manduul. Instead, they bore the campaign hardships together. Although we have no quotes from him at this time in his life, he well might have said the same words that Genghis Khan said to one of his most loyal followers: “When it was wet, we bore the wet together, when it was cold, we bore the cold together.”
