Zheng Chenggong is a famous national hero, and his recovery of Taiwan is even more well-known. At that time, Zheng successfully recovered Taiwan mainly for two purposes, one of which was because the Qing Dynasty did attack a little fiercely, and Zheng Chenggong was a loyalist of the Eight Classics of Zheng'er, so he spent his whole life opposing the Qing Dynasty and restoring the Ming Dynasty, and Taiwan happened to be a suitable foothold. The second is that Taiwan has been China's territory since ancient times, just as Zheng Chenggong wrote to the Dutch colonial leader in a letter of persuasion: "However, Taiwan has long been operated by Chinese, and the land of China is also." There is no doubt about this, even if Zheng Chenggong fights with the Qing Dynasty, it is also a civil war, but when the Netherlands came to colonize Taiwan, it would be an invasion, so Zheng Chenggong also attacked Taiwan with a national ideology.
At that time, after Zheng successfully landed in Taiwan, although there was no detailed record of all the troops, we can speculate. When he fought the Netherlands, he led 25,000 soldiers and horses, which was already most of Zheng Chenggong's troops, after all, he had experienced the failure of the Northern Expedition before, which could be described as heavy casualties. That is to say, Zheng Chenggong's total military strength was 50,000 or 60,000, and the Qing Dynasty alone had hundreds of thousands of soldiers and horses available near the coast, so from the defeat of the Dutch in 1662 when Zheng Successfully completely recovered Taiwan, to 1683 when his descendants surrendered to the Qing Dynasty, how did Zheng Chenggong and the Zheng family resist the Qing Dynasty in Taiwan for twenty-one years?
First of all, there is the problem of civil strife in the Qing Dynasty, the emperor of the Qing Dynasty is very familiar to everyone, that is, the Kangxi Emperor, known as the Emperor of the Ages, Kangxi ascended the throne in 1661 AD, that is to say, Zheng successfully recovered Taiwan, he was only nine years old, completely a small child, so the power was in the hands of Ao Bai. When Kangxi grew up and surrendered to Aobai, this is another five years, and kangxi after surrendering to Aobai still needs a certain period of rectification, as well as San Francisco and other things, these things are enough for Kangxi to annoy, so for a while and a half there will be no effort to care about Zheng Chenggong, after all, Zheng Chenggong is far away in Taiwan, and the distance between Beijing and Taiwan may be a ticket now, but in ancient times it was several months.
Moreover, most of the Manchu Qing army was cavalry, the peoples on the grassland, the most powerful cavalry is the plains combat, a rush can be said to be one enemy three in the face of infantry is absolutely not exaggerated. But Taiwan is not a plain, if you want to go to Taiwan, you still have to take a boat, and when it comes to taking a boat, it is difficult to stop these Manchu cavalrymen, they are experts in riding horses, but many people have never taken a boat at all, and even faint to death, losing combat effectiveness.
Zheng Chenggong's side is different, they are all people who fight on the seashore all year round, and the water is very good. This part of Taiwan is also somewhat easy to defend and difficult to attack, so it is really not an easy task for the Qing army to capture Taiwan. It is a bit of a pity that Zheng Chenggong died a little too early, and zheng chenggong died a few months after the attack on Taiwan, and he was only in his thirties when he died, which is definitely a prime age. If Zheng Chengfu had been alive, the Qing court would have wanted to attack Taiwan in 1683, but it would not have been possible.
