When The Yellow River Turned Red (1403-1406)
"The Great Timur gallops freely across the land of the infidels, cutting through them like a scythe mowing through grass. He knows and fears nothing but the Almighty himself for what the world means to him when he shall visit the afterlife."
- Sharaf al-Din Ali Yazdi, detailing his triumph against the Chinese in the Zafarnama - Book of Victories (1415)
From dusk to dawn, lasting over five days, over 150,000-320,000 men, women, and children are slaughtered. Beijing's riches, from the largest jade to the tiniest golden scrap, were striped to reward the emir's men and enrich his beloved capital, Samarkand. Despite the onslaught, only the tradesmen, from artisans to engineers, were spared to support the war effort or migrate to Tranxosanian proper.
When Bunyashiri - Timur's protege and recently-crowned Khagan of the Yuan Dynasty
[1], and his 50,000 men bore witness after emerging from the Yanshan Mountains, he recollected:
"The capital of my forebears is no longer of my own, being stolen by the rebellious. As retribution, the Commander of the Chaghatay smites it into a smoldering black spot as an example to the rest."
Since 1404, in a calculated strategy to create massive waves of refugees heading toward the south, Timur committed his greatest atrocities across the North China Plain. From erecting spikes of the impaled to be displayed across towns to the disemboweling of selected village peasants and elders, he encouraged his commanders to employ whatever means necessary for them to achieve his grand design. Many cities, especially Taiyuan and Liaocheng, followed the example of their Beijing counterparts as their people were slaughtered in the thousands; the emir ordered the construction of towers to display their heads for the survivors and refugees to witness.
In consequence, hundreds of thousands (350,000-1,250,000) were butchered, and millions flocked towards Southern China to seek sanctuary from the rather indecisive Jiawen Emperor; many accounts cited hauling ships sinking into the depths of the Yellow River due to the brunt of overcrowding. The sudden crisis has strained the already indecisive imperial government as Nanjing faces rapid overpopulation, worsened by food shortages due to the loss of the northern farmlands.
Realizing that the Army was a greater threat to his imperial authority than the princely fiefdoms, he set course for diplomatic couriers to grant amnesty to his uncles and levied 350,000 men to repel the invaders, with Li Jinglong
[2] - son of an influential duke, as appointed commander-in-chief.
In 1405, After witnessing the Ming army crossing through the Yellow River during autumn, Timur splintered his 175,000-manned forces into four mobile formations to avoid capture; Muhammad Sultan, Totkhamysh, and Bunyashiri led their respective detachments. Instead of fighting against impossible odds, he attempted to deprive them until they were weak enough to be crushed, using tactics such as destroying their wagon supply routes, committing night raids against stationed camps, skirmishing marching formations, and razing the farmlands and grain depot. He was able to deprive Li Jinglong's forces; his army dwindled from 350,000 to 225,000.
While his army is regrouping near Jinan, Muhammad Sultan — by Timur's orders, deceives Li Jinglong into believing that he is the emir; he dresses in colorful garbs and carries large ornate yurts to display a pretense of an invading royalty. Marching from Yuncheng, the commander-in-chief's relentless pursuit against him deprived the levies of decent rest, which caused exhaustion and even desertion. Li Jinglong seemed to corner the heir apparent in a mountain valley southeast of Jinan but was too late to realize the emir's ploy as eighty thousand soldiers - veterans of numerous campaigns since Timur's rise, had emerged from the forested mountain slopes. Believing he could still win through sheer numbers, Li Jinglong ordered a massive charge to end the nomadic threat. However, he later discovered that their infamous cavalry (numbering over 55,000) emerged against his rear, with the actual Timur leading its vanguard. Thus, the battle ended in a Timurid triumph when he led the charge against an exhausted army's exposed formation.
With the largest contingent of the Ming Army destroyed within a single battle, the army was free to cross the Yellow River unchallenged. Across the entire year of 1406, Timur exploited such opportunity extensively: They galloped to pillage cities and villages stretching from Xuzhou and Yancheng, eventually diverting towards the Xian to crush the resisting Prince of Jin and finally occupying China's breadbasket region, Sichuan. From the arid plains of Jiayuguan to the shores of Yancheng, all of Northern China is under the reign of the Timurid Empire, closely resembling the Mongol Empire of the old.
However, despite the numerous triumphs, new problems arise: The Yangtze River seems impenetrable due to the patrolling Ming riverboats, and the further they dive into the southern mountains, the further they are from the logistics of Moghulistan caravans, unable to live off the land when the people tilling the fields are gone. His army became more anxious and sickly for home; even Muhammad Sultan himself questioned his grandfather's grand design.
As for Timur himself, he collapsed during his march towards Xian and, for the remainder of the invasion, was carried by an ornate carriage
[3]. For the first time in his life, the emir realizes that death is at his doorstep.

[1] Bunyashiri - or Öljei Temür was granted asylum under Timur's court and converted to Islam. Timur planned to restore Yuan rule across Mongolia and China through him, but some scholars disagreed due to his legitimacy revolving around the Chaghatayid throne.
[2] Li Jinglong was appointed commander-in-chief due to the frequent failures of Marquis Geng Bingwen - his predecessor. Since his appointment, he attempted to recruit 500,000-600,000 levies and was tricked into marching his armies during severe winter, losing countless soldiers in the process.
[3] According to Spanish envoy, Ruy González de Clavijo, Timur was occasionally carried by a litter, especially as he aged.
