Why did Zheng Chenggong recover Taiwan Province Province?

Zheng Chenggong sent his troops to recover Taiwan Province, and Taiwan Province was in a passive position. Because, under the heavy suppression of the Qing army, the southeast coast is in jeopardy, and Zheng Chenggong's strategic room for manoeuvre is getting smaller and smaller. In order to find a safe base to resist the Manchu Dynasty and engage in the great cause of fighting against the Qing Dynasty and restoring sight, he had to send troops to Taiwan Province Province. The following is a concrete analysis of this problem:

After Manchu entered the customs, it gradually gained a foothold in the mainland and its national strength became stronger and stronger; On the contrary, the Ming dynasty was exhausted and unable to organize a large-scale counterattack. Especially after the defeat of Nanjing Battle, Zheng Chenggong suffered heavy losses and his strength was greatly weakened. The space for maneuver is Xiamen and Kinmen, and it is impossible to confront the powerful Qing army. On the premise of shrinking living space, he must expand new "base areas", otherwise he will sit still.

Regarding the above situation, Zheng Chenggong is very clear. At this time, although Emperor Nanming had the support of Li Zicheng and Zhang, he could not resist the attack of the Qing army and had retreated into Myanmar. Only by capturing Taiwan Province Province can Zheng's great cause of resisting the Qing Dynasty have a way out (see Zhao Erxun and others' Biography of the History of Qing Dynasty: "Success is defeated in the south of the Yangtze River, and it is not easy to enter; Wang Gui entered Myanmar, United absolutely, and the situation shrank, so Taiwan Province was adopted. " )。

In other words, the imperial court of Li Yong in the southwest was devastated, and the coastal islands effectively controlled by Zheng Jun could not support the logistics supply of the huge army. In order to continue to compete with the Qing court, Zheng Chenggong naturally turned his attention to Taiwan Province. As Shen, a famous scholar in the late Ming and early Qing Dynasties and known as "Confucius in Taiwan Province", said in "Fu on Taiwan Province": "Golden Gate is not enough to raise soldiers; Xiamen Marukong, is it gathering people? "

At this time, He Bin (also known as He Tingbin, from Nan 'an, Fujian), one of Zheng Zhilong's subordinates, came to Jinmen from Taiwan Province Province to talk about Taiwan Province Province. It is said that before He Bin fled Taiwan Province Province, he secretly sent someone to measure the Luermen waterway entering Daguan Bay. After arriving in Xiamen, he showed Zheng Chenggong a secret map, indicating how the ship bypassed the Dutch battery and landed at Luermen. He Bin volunteered as a guide, which undoubtedly provided favorable conditions for Zheng Chenggong to lead the army back to Taiwan.

Besides, I am familiar with Taiwan Province Province and Zheng Chenggong. His father, Zheng Zhilong, was a thief in Taiwan Province Province in his early years. "Draft of the Qing Dynasty" contains: "Taiwan Province Province, Fujian Island in the sea, lives in Holland with red hair. When Zhilong and Yan Siqi were thieves, they tasted it here. " At that time, Zheng Zhilong recruited tens of thousands of victims in Quanzhou, Zhangzhou, Fujian Province to make a living in Taiwan Province Province. "One person gives three taels of silver, and three people give a cow a head" (Biography of Huang Zongxi's Giving Family Names). In Taiwanese history, Zheng Zhilong was probably the first person to organize large-scale immigration to Taiwan Province Province. In other words, there are many followers of Zheng Zhilong in Taiwan Province Province. Zheng Chenggong was overjoyed. He knows that going to Taiwan Province Province requires a good mass base.

To sum up, there are only two factors that really prompted Zheng Chenggong to make up his mind to recover Taiwan Province. First, he needs a rear base that can supply hundreds of thousands of soldiers. Second, according to various channels (including the information provided by He Bin), understand the deployment of the Dutch army in Taiwan Province Province, so as to know fairly well and win the war. The arrow is on the string, as the saying goes: "Everything is ready, except the east wind." Zheng Chenggong is full of expectations. Once the right seasonal wind comes, his fleet will break the waves and sail to the scheduled target.

The above is just a simple discussion. I will revise the answer, supplement the information and discuss it in detail in the near future. A moment, please.
