Ming Dynasty Double Pillars

In the third month of Jiashen, the capital fell. Chongzhen abandoned his destiny of martyrdom for the imperial city and broke out with his close secret guards, rushing to Shanhaiguan, the most powerful pass in the world. At that time, Wu Sangui was trapped with his family hostages and was in a dilemma. On one side were the invading troops who were threatening and luring him, and on the other side were the Eight Banners outside the Pass, which were eyeing him. The defense line in northern Xinjiang was crumbling. Zhu Youjian quietly resolved the shackles of the Wu family, stabilized the 40,000 Guanning cavalry with the supply of grain and grass, and promised real power. With Shanhaiguan in northern Xinjiang as the northern pillar, he personally took charge of the three-party war situation. At the same time, he sent the prince south to Nanjing to rectify the Jiangnan gentry, collect money and food, train troops and consolidate the foundation, and build the foundation of the south. The north-south dual-pillar pattern was thus formed. Li Zicheng was sitting in the capital, with limited supplies and low military morale. He stormed Shanhaiguan several times but failed. Dorgon stood still and waited for an opportunity to reap the benefits. Zhu Youjian was not in a hurry for a decisive battle. He used inside secret moves to harass the enemy's food routes, used divisive tactics to disintegrate latent alliances between Chuang and Qing, and relied on Xiongguan to defend instead of attack, weakening his opponent's energy step by step. The emperor who was trapped in the palace in the past jumped out of the deadlock of national subjugation and no longer clung to false fame. He locked the enemy in the north and supported the war in the south, and gradually accumulated the power to turn the tables in the three-party game. When the invading army was exhausted and the Eight Banners' patience ran out, all the long-dormant back forces attacked, shattering the established tragedy of Jiashen, rebuilding the country in troubled times, and continuing to write the unfinished road of the Ming Dynasty.
