What did Wei Qing achieve in the Battle of Henan?

In the second year of Yuan Shuo (BC 127), tarquin invaded Shanggu and Yuyang again, killing thousands of officials and people. The struggle between the Western Han Dynasty and the Xiongnu has reached a white-hot level. Emperor Wu of the Han Dynasty decided to fully recover Henan to eliminate the threat of Xiongnu. Henan Province in the Western Han Dynasty, that is, the Hetao area of the Yellow River today, is rich in water and grass, suitable for agriculture and animal husbandry, and its land is close to Chang 'an, the capital of the Western Han Dynasty, which occupies a very important position both economically and militarily. So it has always been a battleground for military strategists. As this war was the first strategic attack launched by the Western Han Dynasty on the Huns, in terms of war guidance, Emperor Wu of the Han Dynasty, after careful consideration, adopted the tactics of riding east and west to avoid the real and attack the virtual, and the implementation of this major military decision fell to Wei Qing.

Wei Qing led 40,000 fighters, braved the cold wind and sand, set out from the cloud (now Tuoketuo, Inner Mongolia), adopted the tactic of "circuitous attack", crossed the cloud, immediately bypassed the west, bypassed the Huns' rear, quickly captured Gaoque (now Hangjinhou Banner, Inner Mongolia), and cut off the connection between the Xiongnu Aries King and Loufan Wang Tong Khan Wang Ting stationed in Henan. Then Wei Qing led the Han army on horseback, flew south, marched thousands of miles, and entered Longxi, quickly forming the situation of Aries King and Loufan King through camp. The Aries King and Loufan King saw that the situation was not good. In order to get rid of the besieged fate, they hurriedly led the troops to cross the river and escape. The Han army captured thousands of enemy troops alive, seized more than one million horses, cattle and sheep, and completely controlled the Hetao area. In this way, the threat of Xiongnu rulers to Chang 'an, the capital of the Han Dynasty, was lifted. Wei Qing was named Changping Hou because of his meritorious service in fighting back against the Huns, and he had 3,800 food cities.

After the war, Emperor Wu of the Han Dynasty adopted the suggestion of Minister Zhu and established Shuofang County in Hetao. The old Great Wall, built along the river in Meng Tian in the Qin Dynasty, was restored and held as a barrier. Emperor Wu of the Han Dynasty also issued a letter to recruit 100,000 people to settle in Hetao area. These measures, to a certain extent, strengthened the Han Dynasty's defense against the Huns.
