In 1688 Zungarian chieftain and warlord Galdan Boshigt invaded Khalkh Mongolian and proceed to trash Erdene Zuu, Khögnö Tarnyn Khiid, and Saridgiin Khiid. Zanabazar, the First Bogd Gegeen of Mongolia and head of the Khalkh Mongols, was forced to flee southward to China. In 1690 news reached Beijing that Galdan Bolshigt had reached Khulun Nuur (Dalai Nuur) area in what is now Inner Mongolia and was proceeding southward along the Khalkh River. On July 26, 1690, Galdan’s army overran Qing outposts south of the Seyelki Mountains in what is now Inner Mongolia. To the emperor’s advisors in Beijing it now appeared as if the Zungarian upstart intended to actually march on Beijing. It was decided to sent two armies north to confront Galdan. First, however word was sent out to Galdan that Kangxi wished to met with him and negotiate a peace treaty. Hopefully this would slow down Galdan long enough to allow the armies to get in place and then administer the coup de grace.
General Fu-ch’uan (1653-1703) was chosen to lead one part of the Qing army. He was the second son of Emperor Shih-su; his mother a third-rank concubine from the Donggo clan. The half-brother of Kangxi, Fu-ch’uan had earlier been given him the title of Prince Yü by the emperor, and on August 6, 1690 Kangxi named him “Generalissimo for the Pacification of Distant Lands.” On August 10 Fu-ch’uan and his army left Beijing and proceeded north through Gubeikou Pass, seventy miles from Beijing, the first pass through the Lesser and Greater Jin Shan (Golden Mountains) near the Jinshanling Great Wall. Kangxi’s younger brother Ch’ang-ning was given command of another army and sent through another nearby pass. Kangxi himself accompanied one of these armies, it is not sure which, to the Great Wall, but soon became ill and had to return to Beijijng.
Jean F. Gerbillon had accompanied the Qing army from Beijing and later gave an eye-witness account of the battle. Toward evening Qing Duke Tong Gougang was killed by Mongol musket fire in what must have been a devastating blow to the morale of the Qing army.
At night-fall the fighting ended and each army returned to their camp. There had been no clear victor, but nevertheless “Generalissimo” Fu-ch’uan sent a dispatch to Beijing claiming the Mongols had been decisively defeated. In fact, further engagements over the next day or two again ended with no clear victor. The tenacious Mongols simply refused to give up. In order to break the stalemate Fu-ch’uan called in a high-ranking lama to begin negotiations with Galdan. An agreement was reached whereby Galdan could return to Mongolia after swearing an oath to his “war-god” (perhaps a Tibeto-Mongolian Buddhist diety), that he would never again invade Qing territory. Thus ended the Battle of Ulaan Butang.
As for Duke Tong Guogang, who had been killed at Ulaan Butong, according to legend a lake sprang up at the site of his death. This lake is now known as Jiangjun Paozi (General’s Lake). There is ger camp nearby and the lake, as well as the battlefield itself, are now minor tourist attractions.
