The Ming Dynasty was founded, Hongwu Dingding and Yongle expanded the territory. After the two sects of Ren and Xuan recuperated, the world was peaceful and the people lived in peace, and it was like a prosperous age. However, the peak will inevitably decline, whether the peak will rise or not, the flow of luck has been difficult since ancient times.
In the early years of Zhengtong, Xuanzong Bintian and Yingzong Zhu Qizhen ascended the throne at the age of nine. The master of the young country is in doubt, and the mother is hanging up the curtain. There are still three Yangs in the court who are assisting in the government. They are old and in charge of the country, and the government is still clear and clear. When San Yang died, the Empress Dowager died, and all the pillars of the court fell. After the young emperor took charge, he showed no concern for the government and only doted on Wang Zhen, the eunuch and eunuch.
Wang Zhenben was an old servant of the East Palace. He was cunning and charming, and he was the best at understanding the holy will. Relying on the emperor's favor, he gradually gained power, formed cliques for personal gain, and deceived the Holy Spirit. Civil and military officials who disobey a little will be demoted or thrown into prison in the most serious cases. The government and the public are as silent as cicadas. The dignified Ming Dynasty was actually controlled by eunuchs, and the rules and regulations were gradually falling apart.
In the autumn of the 14th year of Zhengtong, the leader of the Wala tribe outside the Great Wall also took the lead, organized his troops and horses, and invaded the Datong border in large numbers. The news from the side is urgent, and the smoke is rising everywhere. Wang Zhen always liked great achievements and was greedy for military achievements, so he encouraged the Ying clan to lead six divisions and lead the northern expedition.
Hundreds of civil and military officials throughout the dynasty were admonishing the emperor. They all said that the autumn in the north was cold, food and grass were difficult to sustain, and the enemy's situation was unpredictable. They must not abandon the foundation of the capital. However, Yingzong was young and energetic, so he believed Wang Zhen's slanderous words and refused to listen to loyal advice, so he decided to conquer it himself.
Within ten days, 500,000 elite troops from the capital camp and dozens of important civil and military officials were hastily mobilized to accompany them north out of Juyongguan. The army's journey was chaotic, food and fodder were not available, and the soldiers were exhausted. Before they could engage in battle, their morale had already been weakened. Wang Zhen was an eunuch who did not know the battle formations. He exercised military power indiscriminately. He changed his orders from morning to night and lost control of his advance and retreat.
