A Mongol military general named Khara Bator…
1372 CE
A Mongol military general named Khara Bator (Mongolian: Black hero) is in 1372 surrounded at Khara-Khoto with his troops by the armies of China's Ming dynasty, according to a legend of the local Torghut population.
The Chinese divert the Ejin River, the city's water source that flows just outside the fortress, to deny Khara-Khoto water for its gardens and wells.
As time passes and Khara Bator recognizes his fate, he murders his family and then himself.
After his suicide, Khara Bator's soldiers wait within the fortress until the Ming finally attack and kill the remaining inhabitants.
Another version of the legend holds that Khara Bator made a clearance in the northwestern corner of the city wall and escaped through it.
The remains of the city has a clearance through which a rider can pass.
The defeat of the Mongols at Kharakhoto is described in the Ming dynasty annals: "In the fifth year of Hungu (1372) General Feng Sheng and his army reached Edzina. The town's defender Buyan'temur, surrendered, and Chinese troops reached the mountains of Bojiashan. The ruler of Yuan, Gyardzhipan', fled. His minister... and 27 others were captured, together with ten or more thousand head of horses and cattle."
After the defeat, and also possibly due to real water shortage, the city is abandoned and left in ruins.
Its exceedingly remote location will preserve it from looters.
