In 1542, the mongol Tumut chieftain Li Da became the biggest enemy of the ming dynasty in the north, in exchange for iron, cloth and other materials in the Central Plains, he sent people to Beijing to ask for tribute (in fact, he asked for rewards), resumed mutual market trade at the passes of the Great Wall, and secretly sent troops to harass the towns at the border passes.
When the news came, the Jiajing Emperor Zhu Houxi, who had just used his own opinion, was furious and ordered that he refuse all requests and send Jinyi guards to hunt down and kill Shi Tianjue, the emissary of Li Da, and others.
Therefore, he brazenly sent troops, attacking the Hetao area from time to time, and going deep into the Daming border to plunder people and livestock.
The military attendant of the governor's three-sided military affairs had milled on the order to resist the enemy.
At this time, Xia Yan, who had been expelled by Yan Song, was recalled to the central government and served as the first assistant of the cabinet, he supported Zeng Milling's proposal and strongly recommended it in front of Jiajing, and in this way, in the twenty-sixth year of Jiajing (1547), Zeng Milling was ordered to send troops to fight against the Mongols and achieved a major victory.
It is said that after Xia Yan's comeback, Yan Song's mood has always been unhappy, so he complained to Jiajing the following year, saying that Xia Yan and Zeng Qiao secretly colluded, lightly opened up border challenges, and ruined state affairs.
At this time, the Jiajing Emperor was so addicted to cultivation that he listened to Yan Song's words and ordered Zeng Qian to be arrested and imprisoned, and soon after he sent a message to ask for beheading.
Once Zeng Milling died, Xia Yan was terrified and tried his best to expose Yan Song's crimes such as bribery and perverting the law. Coincidentally, Li Da once again led the army to invade, and Yan Song took the opportunity to provoke Jiajing and said, "This is caused by the border police provoked by Xia Yan and Zeng Qiao!" ”
In a fit of rage, Jiajing sent Jinyi guards to hunt down and kill Xia Yan at the age of sixty-seven. Shoufu was sentenced to capital punishment, and Yan Song's power quickly shook the government and the opposition, and after that, no one in the DPRK and China dared to mention the recovery of Hetao.
In June of the twenty-ninth year of Jiajing (1550), When he led his troops to attack Datong in a big way, Zhang Da, the commander-in-chief of the Ming Army, and Lin Chun, the deputy general of the Ming Army, were killed in battle, and Qiu Luan, who had been appointed as the commander-in-chief of Xuanda because of bribing Yan Song's father and son, was terrified and uneasy, and this house was a wreck, and he had no military ability at all, and when he saw the enemy soldiers approaching the city, he had to show his housekeeping skills, and sent his henchmen to bribe Li Da with heavy gold, begging him not to offend Datong, sparing himself a horse, and turning to attack the important town of Daming.
After agreeing with a smile, he led his troops to the east, quickly captured Gubeikou, and continued to move south with his division, forcing the outskirts of Beijing.
After the "civil change", the Beijing Division was invincible for a hundred years, and the soldiers and civilians had long been slack, and now that the troops led by Li Da had suddenly killed, all the government and the public were terrified.
Jiajing immediately declared martial law at the Nine Gates and ordered the gathering of soldiers and horses to fight. However, most of the soldiers in the Beijing Division were illusory, with only 40,000 to 50,000 forbidden troops, of which the old and weak accounted for half of them, and most of them were still doing miscellaneous service in the homes of the chief soldiers, admirals, and eunuchs.
This is not to mention, there is still a lack of weapons and armor in the army, and the combat effectiveness is really weak. There was no way, Jiajing had no choice but to order the Minister of Culture and Military Affairs to guard the nine gates of the Beijing Division, send generals to the people to recruit volunteers, and at the same time, Fei Tan summoned the defenders of the towns to quickly enter the King of Jingqin.
Soon, the soldiers and horses of Baoding, Yansui, Hejian, Xuanfu, Liaoyang and other places arrived in Beijing one after another, and the datong general Qiu Luan wanted to take the opportunity to ask for credit, and also led 20,000 soldiers to arrive, and under the recommendation of Yan Song, Jiajing ordered him to be the general of Pingyu and restrain the soldiers and horses of the qin king in various towns.
However, all kinds of reinforcements came in a hurry, they did not prepare too much grain and grass, when the soldiers were hungry, they ganged up to rob the nearby people, Jiajing had to order the army to treat, but because of the great construction of civil engineering and Taoist temples in these years, the household department could not come up with money, grain and various expenses for a while, after three or four days, each soldier barely got two thin cakes, seeing the shortage of grain and grass, who has the combat effectiveness to fight against the Mongol Army?
The soldier in charge of military affairs, Shangshu Ding Rukuo, seemed to have no plan for a while, so he went to Yan Song for advice. Yan Song brushed his beard and said to him, "If you fight at the border, everything can still be hidden from the emperor." If today's feet are at their feet and they have suffered defeat, it is obvious to all, who is willing to bear the responsibility? In the old man's opinion, it was better to let the Army grab enough and soon retreat. ”
Ding Rukui heard that if he had a clever plan, he would go back and pass on the orders to the generals, and no one would allow them to act rashly and allow the Li Army to plunder at will. The soldiers then plundered outside beijing for eight consecutive days, and only then did they withdraw under the condition of allowing tribute and peace, and along the way they divided their troops and plundered on a large scale.
At this time, Qiu Luan thought that he could sneak up on Li Da li gong, so he led his army to follow him, but unexpectedly, Li Da suddenly turned back halfway, and the two sides fought an encounter near Changping, resulting in a major defeat of the Ming army, killing and wounding more than a thousand people.
Qiu Luan had no choice but to kill some people along the way, and returned to Beijing to repay Jiajing, who did not distinguish between true and false, and instead promoted him to the post of Taibao.
But Ding Rukui did not have such good luck, the moody Jiajing later blamed him for not moving, allowing Hu Yu to plunder, and ordered the Jinyi guards to take him to prison, Ding Rukui was in a hurry, sent someone to yan song for help, Yan Song told the people who came, with him everything at ease! On the day of the imperial trial, Jiajing angrily rushed to the crown and scolded Ding Rukuo for bringing calamity to the country and the people, while Yan Song only looked at his nose and nose from the sidelines, and did not say a word, until the guards pushed out Ding Rukuo to ask for a beheading, Ding Rukui realized that he had been betrayed by Yan Song and carried a big black cauldron for this battle, so he shouted loudly: "Yan Song misled me——".
