It is said that Wuliang (35): Drive away from Nanliang and move the capital to Guzang
MengXun of the Northern Liang Depression Canal formulated a grand goal of capturing Guzang and unifying Hexi.
Before the fall of Houliang, Nanliang and Beiliang joined forces to attack Houliang; after the demise of Houliang, the military alliance of Nanliang and Beiliang came to an end, and in order to compete for Hexi, the southern and northern Liangs rose again.
At that time, Nanliang bald-haired Tan tan obtained Gu Zang from Later Qin. How to seize Guzang from Nanliang's hands was a long-brewed plan for Beiliang. The two sides attacked and defended, and the war continued. There were three large-scale wars.
The first is the Battle of Junshi. The campaign was launched by Nanliang. In 407 AD, Nanliang Bald led an army of 50,000 to attack Mengxun in Northern Liang. Frustrated, Mengxun waited for work, and the two sides fought at Junshi (present-day eastern Zhangye), where they were defeated by Nanliang. The Southern Liang army retreated to Xi County (西郡, southeast of present-day Shandan County), and due to the increase in numbers, the grain and grass in Xi County were insufficient, and the defenders could not sustain themselves. When bald-haired Tan tan led 20,000 cavalry to carry 40,000 stones of grain to supply Xi County, Frustrated Canal Mengxun took the opportunity to attack, and finally conquered Xi County, captured Taishou Yang Tong, and captured 40,000 stones of military food.
"Jin Shu Frustrated Canal Mengxun Biography": Meng Xun led a foot ride of 30,000 bald hair, second to Xi County. The wind came from the northwest, and the air was five colors, Russian and dim. To the most beautiful, thousands of households and return. Yu Tan chased after Meng Xun and Meng Xun in poor springs, and Meng Xun attacked, lost, and took advantage of the victory to Gu Zang, and thousands of households descended. Fear, please, and return home.
The second is the Battle of Poor Springs. It was Nanliang who provoked the incident this time. In 410 AD, The Bald Man of Southern Liang attacked Northern Liang and plundered more than a thousand households and returned. In order to retaliate against Southern Liang, MengXun personally led an army of 30,000 to fight against baldness. At this time, there was a sudden sandstorm, and the wind came from the northwest, and after a while the day was dark. Overcoming the effects of bad weather, Mengxun led his army to Xianmei (present-day Yongchang County), not far from Guzang, and also abducted thousands of residents to return.
Nan Liang's bald haired Tan Tan could not sit still and decided to personally pursue the Northern Liang army. The subordinates vigorously advised that the troops would be defeated, but the bald man did not listen, and said angrily: "Frustrated by the canal Mengxun invaded my frontier, destroyed my crops, deceived people too much, committed a terrible crime, I want to be ashamed of the snow, er, do not demoralize!" He led his army to Qianquan (present-day eastern Zhangye) and ordered the army to camp and prepare for a decisive battle with Northern Liang. Frustrated, Monson did not play his cards according to the norm, and he took advantage of the unstable foothold of the Southern Liang army and launched a surprise attack. Bald was caught off guard and returned in defeat. Frustrated, Mengxun did not give up, taking advantage of the victory to pursue Guzang, and more than 10,000 people outside the city surrendered to Northern Liang. The bald man was frightened and sent the hostages to ask for peace, but He withdrew his troops and returned.
The third is the Battle of Guzang. After the Battle of Qianquan, Nanliang was seriously injured and could no longer gain a foothold in Guzang. The bald-haired Yu Tan had to abandon Gu Zang and retreat to Ledu, leaving Dasi Nongcheng Gongxu to guard Gu Zang. As soon as the bald man left on his front foot, Guzang rebelled, and the army and the people elected Jiao Lang to occupy Guzang. Frustrated, Mengxun commanded 30,000 troops and besieged Guzang. Jiao Lang could not resist and Kaesong surrendered. At this point, Beiliang occupied Guzang. After entering the city, Fengqu Mengxun rewarded The Wenwu soldiers at the Qianguang Hall of Guzang City.
In October 412, Mengxun moved the capital of Northern Liang from Zhangye to Guzang.
"Jin Shu · Depressed Canal Mengxun Biography": Ru and Mengxun moved to Guzang, with Yixi eight years to the throne of Hexi, amnesty in the territory, changed the Yuan Xuanshi. Put bureaucrats, such as Lü Guang as the story of the King of the Three Rivers. The palace, from the city gate to the view.
After capturing Guzang, Mengxun took advantage of the victory to pursue, and several times led his troops into the capital of Southern Liang, Ledu, in an attempt to completely overthrow Southern Liang. But I did not expect that when the Western Qin State took advantage of the decline of Southern Liang, it attacked the capital of Ledu and Southern Liang perished.
To this end, Northern Liang and Western Qin competed for the Huangzhong area in the east of present-day Qinghai, and the two sides launched a tug-of-war, and you came and went, and each other won or lost. Because Western Liang seriously threatened the security of Northern Liang's territory, Northern Liang and Western Qin made peace, and the two sides called off the war.
Next, Frustrated Canal Mengxun concentrated his forces against Xiliang, and the great showdown between Northern Liang and Western Liang was about to erupt.
